:shocked::shocked::shocked:

Would not want to be moving my PC much with that installed.

[wickedld9]

Looks heavy, might have to give it a go. Price.....wow.

[Chewbenator]

Oh God. 3kg? That's three EeePCs.

[Tonucci]

Wow, its beautiful ! :clap:

If someone lap it until it forcefully become HDT it will be perfect :p:

[loonym]

Very nice for the boards on the rack but I don't think I'll hang any. :D

[coo-coo-clocker]

need to mount the mobo flat or have some suspension hangers if you have your mobo vertical in your case! Even then, you'd probably not get even contact with it being that heavy...

[apexracing]

Should work well, provided it actually mounts firmly.

[IKIKUINTHENUTZ]

Very nice indeed

So who will post a user review on it? :D

[saaya]

no pic or link?

[Dami3n]

3kg??:down:

[Toferman]

Good mother of the smelting gods, we accept your offering. :):p:

[ChinStrap]

soooooooo.... whos gonna be selling it? :)

[AndrewZorn]

I thought all the normal ones were nickel-plated copper. So why is this one 3kg instead of 1?

[Tonucci]

I thought all the normal ones were nickel-plated copper. So why is this one 3kg instead of 1?

Only the base and heatpipes were made of cooper :up:

[Fungus]

a thing of beauty!

[fragmasterMax]

99 dollars wtf?
limited quality!!!?
Come on thermalright, you can do much better than this.
(i'm disappointed by the price, but no doubt this will be the reigning cpu cooler champ)
damn you thermalright

[Swatrecon_]

looks like the statue of liberty.

[NapalmV5]

this the real true thermalright :clap:

99$ ? ill take two! :)

[brinox]

i wouldnt dare jump to conclusions with 3kg of copper... thats a lot of heat capacity with not as much ability to move the heat over to the air...

[awdrifter]

That looks cool. But $100 + $20-30 for two fans are almost in water cooling territory. Can it compete with water?

[Spawne32]

source? doesnt look like a TRUE at all, far to small width wise from what i can tell on the pic

[NapalmV5]

^ lol there were a bunch who suggested the black true 120 was also a fake

[Spawne32]

^ lol there were a bunch who suggested the black true 120 was also a fake

the difference was a few months ago when asked about this at computex, thermalright stated there would be no copper edition as it was too heavy on the motherboards to be practical for production, and it raised saftey concerns.


Edit: yes it does look like a ultima 90 copper edition judging by the width

[NapalmV5]

if its not the true120.. maybe copper ultra90 ?

[Spawne32]

since theres no source on this and no official release from TR, i sent a email off to hank, see if theres any official specs or dates or anything.

[STEvil]

i wouldnt dare jump to conclusions with 3kg of copper... thats a lot of heat capacity with not as much ability to move the heat over to the air...

False.


Guys, 3kg is nothing unless you're tossing your machine around like a prat.

[@@@@]

Waiting for the reviews but don't worry the x58 motherboards has 8 layers now so it is much thicker than other motherboards it should be able to handle the stress of a estimated 3kg CPU heat sink

[spursindonesia]

Is copper made fin really that heavy compared to aluminum made one ? Can't believe the difference that huge beetween the two.

[Pyroe_Inc]

Aluminum: 2.70 g·cm^3
Copper: 8.96 g·cm^3

Over 3 times the density.

[spursindonesia]

Oh, i see, dang, the thing can really be used as weapon thrown at the enemy, LOL. :D

[largon]

i wouldnt dare jump to conclusions with 3kg of copper... thats a lot of heat capacity with not as much ability to move the heat over to the air...What?
:shakes:

[RejZoR]

Why the hell no one uses retention mechanism like on Akasa Evo Blue (AK-922)!? Especially with weight like this...

[redrumy3]

im pretty sure its the ultra-120

earlier pic of it

[BulldogPO]

Too heavy and too pricey, gets too close with watercooling.

[RejZoR]

Well, you have to understand that 3 kilos of copper aren't cheap. Especially when we're talking about crafted copper, not just solid block of it...

[AuDioFreaK39]

OMG. the true pwnage tool

*camps out for that :banana::banana::banana::banana::banana:*


Please tell me there will be a Socket LGA 1366 version :)

[tajoh111]

I think 99 is the cheapest they can sell it for. If this thing is limted to 3000, I wouldn't doubt that this product is being release for only publicity and get the undisputed crown for performance. I am guessing dealer cost for this to be 66 dollars. Thats only 200,000 dollars which is chump change when you remove expenses. Take into account the cost of 3kg of copper, manufacturing, heatpipe and etc. Its pretty easy to see why this cost 99 dollars.

There are atleast 3000, people in this world that probaly think hell with performance, its a true thats copper and it's beautiful. Especially when it hard to get a cooler which is 500g of copper for 30 dollars, you begin seeing that their is actually value here. Sure it might be knocking on cheap waters door. But people don't want the annoyances associated with water such as installation and want to stay on air. This will probaly beat a 100 water kit anyways.

[tiro_uspsss]

I'm willing to buy..... but I aint believing it till its officially launched by TR - y? cause if it is 3kg, I'm willing to bet thats too much as per socket quide-lines (i'm just guessing tho :D - anyone know where to look this stuff up, ie intel/amd white papers etc? )

[naokaji]

found this on the Zalman website, they have it at the bottom of the product descriptions:
The maximum weight for a cooler is specified as 450g for Intel Socket 775/478 and AMD Socket 754/939/940.

or to say it differently, every cooler that is considered by the enthusiast community exceeds the weight spec's by a lot.

:shocked::shocked::shocked: thats that low, i wonder if thats real! :D - cause like u said, that pretty much means every ethusiast hs is over that :eek: :shrug:

[LuckyNV]

:shocked::shocked::shocked: thats that low, i wonder if thats real! :D - cause like u said, that pretty much means every ethusiast hs is over that :eek: :shrug:

It is real, but its an Intel spec remember, something like this will always be heavily exaggerated just to cover all bases.

[demonkevy666]

Why not get the heat pipes to touch directly ?

it seems to work much better, beside the bottom doesn't need to be that huge.

that would lower the price and weight by a few $.

it also looks like it's got more pipes then a normal one.

[Kondik]

It has 6 double Heatpipes but looks to narrow to me .. Ultima , It doesn't look like TRUE to be honest yet still it's amazing ...

6KG's Thermalright IFX -14 anyone ? :hehe:

Add: After I saw the pics from redrumy3 I started to cry

[bowman]

Please tell me there will be a Socket LGA 1366 version :)

Just needs a new adapter..

Anyways, aluminium case, aluminium mobo tray (which already bends).. And this thing. Interesting recipe at least :p:

[tiro_uspsss]

if thing does come out & if I do get one, i think i'll strictly mount it on a mobo that is horizontal ;)

[brinox]

False.

so you mean to say that aluminum does not in fact radiate heat better than copper?

[drteming]

I will buy it just as an art piece and display it on a shelf. Imagine how pretty it will be with a coat of green patina. $99 is cheap for an all copper postmodern industrial sculpture.

[cegras]

The Ultima doesn't have bent 'wingtips' though.

Also, for anyone who doesn't get it yet: Copper is simply better than aluminum for heatsink applications. The problem is that marketing has brainwashed you - the only reason why aluminum is used is because it's cheaper and copper is really not worth the small performance increase.

[ryboto]

Are you serious? Explain it to us how that's possible.

you cant forget that aluminum is also much lighter, the other main reason why companies use aluminum

[[XC] Synthetickiller]

I want to see it weighed. 3kg? pssh, no. Whats the difference? Copper fins? that's not 2/3 of the mass of the heatsink. Did they add extra copper just to get to this weight? I would not a trust a mobo to hold up 6.6 lbs + the weigh of a fan on the cpu. There would be more contact on the lower half of the cpu just due to the weight shift unless you had some industrial quality brace.

Its pretty and will probably do a very good job of cooling and looking pretty, but unless my mobo is horizontal, forget it.

[Baron_Davis]

so so awesome...im getting one

[Baron_Davis]

the main reason they use aluminum is cause steel is cheaper and they cant profit as much from it. Whatever gets them more $$$ for no intelligent reason is their motto...

ps. im not being a hypocrite for wanting the TRUE copper...yes it's expensive and "flashy" but I coulda gone for the Ninja copper if i was a drone. The reason I'm 99% getting one is because the performance you will get from it with a nice push/pull setup using high powered fans should be amazing. Remember, since copper's thermal conductivity is much MUCH higher than aluminum's, you need really good fans + air flow in your case to cool this baby down and get rid of all the heat it stores.

[ryboto]

That's crazy talk. The EXACT same amount of heat that was produced when you were using an aluminum heatsink will still be produced, not more, not less. Assuming you're using the same CPU at the same voltage/clock. The only thing that's changing now is that your conductive surface conducts heat much much faster. In both cases(Al/Cu), the limiting factor for heat transfer is the convective heat transfer resistance, since heat transfer to the air is dependent on the convective heat transfer coefficient, which is directly related to the velocity of the air over the surface you are cooling. So, in either situation, high speed fans will help. You wont need higher speed fans just because it's all copper.

Buddy, copper has the 3rd highest thermal conductivity on Earth, behind diamond and silver. That means that whatever heat was transferred to the aluminum was dependent on the aluminum's ability to conduct heat energy. Now, since copper's conductivity is HIGHER, much MUCH higher (401 vs 237 W/(m·K)). That means that at any given time, it will be transferring and thus storing more heat energy than the aluminum version. Soooo that means that in order for the heatsink to not become overpowered by its own thermal conductivity, it needs to GET RID of the heat it conducts at a faster pace as well. Hence, the reason for more powerful fans.

Take a heat transfer course and what I was saying might make more sense to you. The rate of heat transfer to the air is dependent on two things, a thermal gradient and the convective heat transfer coefficient. The thermal gradient is dependent on the temperature of the surface, and bulk air temperature. Now, the rate of heat transfer directly increases with increasing temperature delta, Q = h A (T-Ta). The hotter surface aids in cooling already. With the same heat source, same convection type(forced/unforced), copper will cool the surface better.

[Baron_Davis]

That is purely theoretical. You forget that the heat transfer that occurs between the CPU and the copper heatsink is greater than that of the heatsink and the air. Although copper's heat capacity is a lot bigger than aluminum's, eventually, if the fans aren't getting rid of the heat at a greater rate than the heatsink is absorbing it, then the copper will start getting hotter and hotter and become useless.

Think of it like this:

1st hour: a lot of heat transferred to heatsink, not so much going out of the case
2nd hour: ambient case temps start increasing, copper heatsink starts struggling trying to stay cool
3rd hour: high ambient case temp has overpowered the heatsink, heatsink is now useless

That's why just looking at thermal conductivity doesn't tell the whole story. In a lab, yeah it does, but in real life it does not.

No, it wont become hotter and hotter, it will, like any heat exhanger, reach a steady state temperature given a consistent heat load. What you're proposing should happen to ANY heatsink. I'm not just looking at the thermal conductivity, I'm considering the convective conductivity which will increase. If a lab simulates "real life", how is it not accurate? Just stop misinforming people. A Copper heatsink does not need higher airflow than an aluminum one. If your logic even was applicable, then this would be true for aluminum heatsinks as well.

An aluminum heatsink doesn't conduct as much, so its fans can remove the heat from the case without becoming overburdened. So this gradual temperature increase would take a lot longer. On a copper heatsink like the TRUE, which is designed extremely well, this gradual increase in temperature would take a lot less time, and while for the first hour or so, it would cool rather well, the ambient temp would start to "choke", and things would go down hill from there.

You CANNOT expect a copper heatsink to cool well if you aren't removing that excess heat from the case. That's all I'm saying.

And for ^^^ to happen, you need better cooling. If you already have good cooling, this is obviously not an issue. Just don't waste money on a $100 heatsink only to slap on some weak ass 800rpm "silent" fans on it.

Theres no "EXCESS HEAT"! it's the same heat source...Copper doesn't generate heat you know...it just conducts it faster, REMOVING heat faster under the same conditions. A copper heastink with an 800rpm fan will perform better than an aluminum heatsink with the same fan. It might be a marginal improvement, but it will conduct heat faster. If an aluminum heatsink doesn't conduct as much heat, its fins would be cooler than a copper version, and in that sense, you're going to have a hotter CPU.

Why will the ambient temp "Choke"? any decent fans are basically removing the entire case volume of air every minute, so the ambient air is going to be close to ambient room temp, and on top of that, you'll reach a steady state. Things aren't going to generate more heat because you change your material of conduction.

First off, yeah a copper heatsink will be removing more heat but at the cost of ambient temperature rising IF YOU DON'T HAVE GOOD AIR FLOW.

Second, if you don't have intelligent placement of good fans, your ambient temp will indeed choke. Getting good air flow in most case is very hard, and I think you're being pretty idealistic in thinking that a case worth of air is getting moved every minute. Grills kill air flow. Poor case design does the same, and most cases (even $300 ones) don't have close to the perfect air flow you seem to think exists. Again, consumer PC's are not a lab. We don't live in a vacuum, figuratively speaking. I think you're applying absolute scientific laws in a chaotic environment without thinking outside the box and realizing that there are a few important factors that kill this naive thinking.

[ryboto]

First off, yeah a copper heatsink will be removing more heat but at the cost of ambient temperature rising IF YOU DON'T HAVE GOOD AIR FLOW.

Those scientific laws apply to the real world. Case air flow has NOTHING to do with the fact that a copper heat sink will perform better than an aluminum heat sink. Here's the skinny. An aluminum heatsink transfers heat slowly, so, compared to a copper version, it's bulk temperature is lower. To compensate, and increase heat transfer from the aluminum version, you can only increase the airflow, to increase the convective heat transfer. Because copper is warmer(due to greater heat capacity and conductivity), the temperature gradient for convective heat transfer is higher, so heat transfer to the air is greater.

Given the same airflow, the copper heatsink will outperform the aluminum. If you put the two versions in the same system, the copper will provide better cooling. This might be marginal though, considering the heatpipes on most coolers are nickel plated copper, so the only new copper here is the fins.


Either way you look at it, you're going to have to deal with the same amount of heat if your system isn't changing. You use an Aluminum heatsink, the rate of heat transfer is lower, so the rate that you heat the ambient case air is lower, but your CPU is hotter. Use a copper heatsink, rate of heat transfer to the air is higher, ambient might rise, but CPU temperature decreases.

[RejZoR]

Lets wait for coolers made out of diamond. 2 to 4 times the copper thermal conductivity. Don't ask about price... :P

just make a diamond microprocessor, thermal limits on that would mean we probably wouldn't need a heatsink.

[Biker]

I'm going to buy 10 and then sell it back when Copper reaches $999/kg :D

[@@@@]

it could happen they could use synthetic Diamonds but your right the price would be unbearable

[RejZoR]

Synthetic of course. Getting natural diamond of that size (or even 1/4 of it) is pretty much impossible.

[PrometheusCon]

Hell... I'll buy one just cause it's so shiny. I won't even use it. Just keep it in a acrylic box and have a small 5 watt bulb inside to make it GLOW

[demonkevy666]

stock True nickel plated says it weights 790G grams

there is no way copper would make this weigh 3KG

only a Stainless steel one would weigh that much.

I'm betting this would be about 1,000-1500 grams Max.

I like that that carbon idea instead of silicon.

why isn't anyone using it to make dies because of it's meltting point of

Hasn't there been a lot of news about Graphene? Silicon still works for the current designs.

[nfm]

p of nickel: 8.902 g/cm^3
p of copper: 8.940 g/cm^3

p = m/V
V = m/p

V = 790 g / 8.902 cm^3 = 88.744 cm^3
m = 88.744 cm^3 * 8.940 g/cm^3 = 793.37 g or 0.793 kg :shrug:

Sure. But what about other characteristics, like resistance?

You use an Aluminum heatsink, the rate of heat transfer is lower, so the rate that you heat the ambient case air is lower, but your CPU is hotter. Use a copper heatsink, rate of heat transfer to the air is higher, ambient might rise, but CPU temperature decreases.

Also remember the difference between heat, thermal energy, and temperature. Heat is the transfer of thermal energy. The hotter something feels the more thermal energy it is transferring.

So first we have to ask ourselves what we're transferring the thermal energy to. It turns out that air has a terrible specific heat and has trouble absorbing the energy fast enough causing a build up of average thermal energy, or temperature. We constantly need to be pushing the air that has already reached or is nearing the average temperature of the system out of the way. The greater the temperature difference between the air and the heatsink the faster the transfer of thermal energy.

Comparing copper to aluminum is tricky. Copper may not be able to dissipate the thermal energy as fast as aluminum, but because it has a higher specific heat it can contain and absorb the energy at a higher rate. From what I understand aluminum cannot contain thermal energy worth crap. If you heat up one end of an aluminum rod the other end will have a significant temperature difference. This is why if you remove something on an aluminum sheet from an oven at 450 degrees you can immediately touch the sheet. Copper on the other hand is great at containing and transferring the energy but is not so great at getting rid of it. This is why heatsink manufacturers us copper to transfer the energy and aluminum to dissipate it.

So if aluminum heat pipes were used you'd end up with less energy transfer away from the origin and because the air can't absorb the concentrated energy efficiently you'll end up with a higher average thermal energy at the origin, or high temp CPU.

With the all copper TRUE the thermal energy will be able to disperse more evenly to the far corners of the heatsink, however in theory without aluminum's inability to contain the energy, despite this all copper monstrosity's ability to contain more energy it should result in a higher temperature.

[ryboto]

Utterly ridiculous. Really, did no one study heat transfer? So what if it's heat capacity is greater, it means it can handle greater heat loads, it doesn't mean it "holds onto heat more tightly"...Like I said before, with higher surface temperature comes the added benefit of increased temperature gradient with the ambient air, which directly INCREASES the convective heat transfer rate.

Sure The copper sink will be warmer, because the rate of heat transfer to/through it is greater, and because it can store more energy, but that energy will never be greater than the thermal source because of the temperature gradient that will exist with the bulk air. Who taught you guys this stuff?

This is why heatsink manufacturers us copper to transfer the energy and aluminum to dissipate it.
You have a source to back that up?

here's a sweet and short discussion on the matter, because I can't seem to get the point across.
http://www.jonnyguru.com/forums/showthread.php?p=43184

[cegras]

Marketing has gotten you to absorb the 'copper for transfer, al to dissipate.'

The correct statement should be aluminum used for more cost effective heat transfer.

And I think baron_davis has a point, ryboto. Over time the copper will equilibrate with a higher TEMPERATURE given constant input of heat. Heat != temperature.


Also, ha! That thread was mine : )

[HousERaT]

I'll consider it if it will work with x58. Looks like the kind of heatsink I want next.

[AndrewZorn]

Transfer IS dissipation. Dissipation IS transfer. Right?

it depends on the context.

[Pyroe_Inc]

stock True nickel plated says it weights 790G grams

there is no way copper would make this weigh 3KG

only a Stainless steel one would weigh that much.

I'm betting this would be about 1,000-1500 grams Max.

I like that that carbon idea instead of silicon.

why isn't anyone using it to make dies because of it's meltting point of

The melting point of graphite is 3550ºC (6332ºF)

The melting point of Silicon is 1410ºC

Stainless steel is less dense than pure copper.
Graphite is not suitable for semiconductor. graphene is, they are essentially the same, but the technology is not there yet.

p of nickel: 8.902 g/cm^3
p of copper: 8.940 g/cm^3

p = m/V
V = m/p

V = 790 g / 8.902 cm^3 = 88.744 cm^3
m = 88.744 cm^3 * 8.940 g/cm^3 = 793.37 g or 0.793 kg :shrug:

if the entire true was made out of alu and that was swithed with copper, it would weigh approx 2622g. But since it is part copper part alu it cant be measurred that way.
The nickelplating is very thin and won't mean much for the equation.

[ryboto]

Marketing has gotten you to absorb the 'copper for transfer, al to dissipate.'

The correct statement should be aluminum used for more cost effective heat transfer.

And I think baron_davis has a point, ryboto. Over time the copper will equilibrate with a higher TEMPERATURE given constant input of heat. Heat != temperature.


Also, ha! That thread was mine : )

The copper itself might be warmer, but that's only because it's conducting heat faster. Look at the equations

1.) conduction through heatsink from heat source
Q1= K*A*(T1-T2)
where Q1 is the heat load, or rate of heat(watts from a CPU), K is the thermal conductivity, A is the interfacial surface area, T1 and T2 are the heat source temp and heat exchanger temp resepctively.

2.) Convective heat transfer from heat exchanger to air
Q2 = h*A*(T2-Ta)
where h is the convective heat transfer coefficient of the fluid(air in this case), and Ta is the bulk temperature of the fluid(air). Heat transfer to the air is dependent on the properties of the air(temp/velocity/h), and the temperature gradient between the exchanger and air.

If we had two heatsinks of the same design, the only difference being their material of construction, Al vs Cu, the number we change in equation 1 is K. T1 and T2 will be different for Al vs Cu. The base temp, T1 will be lower, T2 will be greater, meaning a lower CPU temp. In Eq. 2, the heat transfer is highly dependent on the temperature difference, if T2 is greater, the heat transfer to the air will increase.

The only variable changed between the two is K, the heat transfer is determined based on the conductivities, therefore Copper is the better choice.

In short, conductivity is dependent on the material of the heatsink, heat transfer(or dissipation) to the air is dependent on the properties of the bulk air.

[Xope_Poquar]

Utterly ridiculous. Really, did no one study heat transfer? So what if it's heat capacity is greater, it means it can handle greater heat loads, it doesn't mean it "holds onto heat more tightly"...Like I said before, with higher surface temperature comes the added benefit of increased temperature gradient with the ambient air, which directly INCREASES the convective heat transfer rate.

Sure The copper sink will be warmer, because the rate of heat transfer to/through it is greater, and because it can store more energy, but that energy will never be greater than the thermal source because of the temperature gradient that will exist with the bulk air. Who taught you guys this stuff?


You have a source to back that up?

here's a sweet and short discussion on the matter, because I can't seem to get the point across.
http://www.jonnyguru.com/forums/showthread.php?p=43184


I do fully apologize. I'm looking at a text that contains the specific heat and heat transfer coefficients of several materials. It shows aluminum with a lower specific heat and higher heat transfer coefficient. It turns out it's a misprint. The decimal is in the wrong place on the aluminum's coefficient.

Well what I said would be true given aluminum could dissipate heat 10 times what it actually does. :p:

Yep, I was just summing up what I felt was baron's point.

The copper is warmer because it's doing it's job better. Al is cooler, not because it is dissipating heat a lot faster, but because there wasn't much there to begin with : D

[dengyong]

That thing would have to be solid copper to weigh 6.6lbs (3kg). It might weigh 1lb.

Don't you guys get it? The prettier the material, the better it cools!

[Baron_Davis]

I think the source meant 3lbs, not 3kg. The Ninja Copper is around 1kg, so let's say the copper TRUE is 3lbs, 3/2.25= 1.33kg. Sounds about right...

My head was about to explode when people were saying that Aluminum would be better at getting rid of heat than Copper.

I was just reading thru this thread and I've come to a few conclusions:
1) Lots of people like to argue any point at all just for the sake of arguing!
2)A great many of you people are a hell of a lot smarter than I am.
3) I always thought copper was used for the base and alum used for the fins as copper transferred heat faster but aluminum dispersed the heat faster.
That's what I think not know and reading here I may well be wrong.
4) Pretty looking heatsink.
5) We'll find out how effective it is when someone here tests it and not before.

It'll probably be effective, just how effective over the original version is questionable, since think aluminum fins are probably pretty effective as is..

Man, that $99 is looking attractive as a good start for a watercooling loop instead.

a 99 dollars watercooling loop (new, not used parts) are almost equal or it could be wrost than the thermalright ultra 120 extreme. besides, not everyone will want to go through the hassels of watercooling and worrying about their loop whether is leaking or not. On the other hand, air cooling is way faster and easier to mount or disassemble.

[Bo_Fox]

Regarding all this debate over copper vs. aluminum.. let me tell you from years of my fetish with customizing my own heatsinks... I've customized them in so many different creative (unique) ways that none of you guys have ever done that I've gotten so close to patenting a few of the designs.

In short words:

Copper fins are better for high-speed air flow.
Aluminum fins are better for low-speed air flow. (EDIT: cheaper and lighter, plus the difference from copper is not really noticeable)



I know for a fact that copper is more efficient at heat transfer as long as the air flow is fast enough. Say, if copper can transfer heat more quickly from the base to the heatpipes than aluminum, the copper fins might just as well transfer more quickly via HIGH air pressure/flow. Many of us only pay attention to the CFM of air flow, while overlooking another important aspect of the inch or mm-H20 (or Hg) of the air pressure. For example, Thermaltake's Volcano 12 fan (which is 80mm x 32mm and has only 3 blades -- http://www.thermaltake.com/product/Cooler/Retail/A1745/a1745 http://www.thermaltake.com/product/Cooler/Retail/A1745/+A1745_image/fan.jpg) exerts higher pressure than a similar 5-blade fan operating at the same RPM. It actually gives lower CFM than a 5-blade fan would, but the pressure more than makes up for it (given that the fan is 38mm thick rather than 25mm). The noise generated remains pretty much the same.

It is very important for the copper fins to remain as thin as possible and also as close together as possible, while being optimally soldered to the heatpipes. As long as the dust does not build up, it is what made Thermalright's XP-90c perform better than the larger XP-120, at 2000+rpm fan speeds.

Although aluminum fins do pretty well with heatpipes, copper is just better if you have at least a 2000+ rpm fan blowing directly on it. I do not know exactly what the threshold would have to be (airflow CFM and air pressure) in order for copper fins to be more efficient than aluminum, but let's just say 2000 rpm for most heatpipe heatsinks out there. Zalman's hugely popular CNPS9700 would be nowhere nearly as good if the fins were aluminum instead of copper. On that heatsink, aluminum fins would perform just as well as copper only if it came with a super-quiet fan (say, 1500 rpm max). For fan-less heatsinks, aluminum is a god-send!

At any fan speed, copper is a better material for heat transfer vs aluminum. I have done term papers on this, it's thermodynamic fact. My Zalman did come with a low speed fan(1500rpm is in no way at all super-quiet, you don't see that until you go below 1000rpm), and it worked fine. Unless you can show us some testing results proving your assertion, it's just wrong to make these kind of claims about copper v. aluminum. The heat transfer from the material to the air is a function of the air and temperature delta, not a function of the material.

[ryan92084]

from my understanding of just basic principles

1)copper gives you lower cpu temps while causing your case to heat up more quickly under load
2)alluminum gives you a higher cpu temp but heats your case up more slowly
3)under a constant load with inadequate ventilation both sinks will even out eventually (after the internal case temperature stabilizes, this should happen faster on the copper which might be why people think its worse)
4)under constant load with adequate vetilation (including cool air intake) the copper cooler will perform better

[NotFred]

My take on the Copper Vs Aluminium argument:

Alternative way of visualising things, working backwards (I find this easier):

Let’s consider the computer as a single unit. It has energy going in from the power cable, and energy leaving in the form of hot air.

No matter what is going on inside with different heat sinks etc, we have the same energy going in. Also, for the same case, we have the same amount of airflow produced by the fans, and so the same volume of air leaving the case.

For a steady state, the energy entering and leaving the system must be the same. Therefore, for a fixed energy input, and a fixed airflow, we must stabilise at a fixed temperature of the air leaving the case, no matter what we have changed inside.

How does this affect our CPU? The heat sink provides a temperature gradient between the CPU and the case air. The better at conducting heat the heat sink is, the shallower this gradient can be (i.e the closer in temperature the CPU can be to the air). This means that, as case air temperature is fixed for a given heat input and airflow, a heat sink with higher conductivity will give a lower CPU temperature, as there will be a lower temperature gradient between the CPU and the air.

:up:

The key thing to keep in mind is that aluminum is way, way cheaper, easier to work with, and the performance increase going from a hybrid design (Al fins w/ copper where it really counts like the base) to pure copper really doesn't give that much of a difference.

I think you misunderstood him. Cause you're both saying the same thing.
Copper is better. You just have to have more airflow, to be able to notice the difference...

[Calmatory]

An aluminum heatsink doesn't conduct as much, so its fans can remove the heat from the case without becoming overburdened. So this gradual temperature increase would take a lot longer. On a copper heatsink like the TRUE, which is designed extremely well, this gradual increase in temperature would take a lot less time, and while for the first hour or so, it would cool rather well, the ambient temp would start to "choke", and things would go down hill from there.

You CANNOT expect a copper heatsink to cool well if you aren't removing that excess heat from the case. That's all I'm saying.

And for ^^^ to happen, you need better cooling. If you already have good cooling, this is obviously not an issue. Just don't waste money on a $100 heatsink only to slap on some weak ass 800rpm "silent" fans on it.

You sir, should go back to school. :ROTF:

You also say that when you use better GPU cooler(neither blowing heat out), your CPU temperature lowers as the card doesn't put so much hot air in the case because the GPU temperature is lower? :clap:

Edit: Some of the reasons why copper is better:
The bottleneck might lie in heat transferring between fins and heatpipes. Using copper will help this a little.
The another bottleneck might lie in the fact that alu fins are too thin. The heat doesnt transfer to the center of the fins. The temperature in the center of the fin is lower than nearby the heatpipes. This means that heat doesn't conduct to the air as well as what it conducts at the edges(near the heatpipes). Actually, if the delta between ambient and the spot temperature halves, the heat dissipation halves aswell.

I am not sure how thin the fins are(IIRC they are 0.4 mm, but I might be wrong, correct me if necessary), but if the fins were 0.53 mm, the heat should(in theory) transfer as well to the middle of the fins as with 0.4 mm copper fins. They could've used a lot thicker alu fins, but the costs would've gone up, with the weight and "FULL COPPER HEATSINKS OMG" sells better.

[tiro_uspsss]

Remember, since copper's thermal conductivity is much MUCH higher than aluminum's, you need really good fans + air flow in your case to cool this baby down and get rid of all the heat it stores.

epic fail... seriously...

Buddy, copper has the 3rd highest thermal conductivity on Earth, behind diamond and silver. That means that whatever heat was transferred to the aluminum was dependent on the aluminum's ability to conduct heat energy. Now, since copper's conductivity is HIGHER, much MUCH higher (401 vs 237 W/(m·K)). That means that at any given time, it will be transferring and thus storing more heat energy than the aluminum version. Soooo that means that in order for the heatsink to not become overpowered by its own thermal conductivity, it needs to GET RID of the heat it conducts at a faster pace as well. Hence, the reason for more powerful fans.

whats it with the word 'store' - theres thermal conductance & thermal resistance

u make it sound as if a Alu HS doesnt need as powerful fans :shakes:

That is purely theoretical.

what a crock of poo - I guess its only known as the Laws of Physics in a lab too then? :rofl: :down:

You forget that the heat transfer that occurs between the CPU and the copper heatsink is greater than that of the heatsink and the air. Although copper's heat capacity is a lot bigger than aluminum's, eventually, if the fans aren't getting rid of the heat at a greater rate than the heatsink is absorbing it, then the copper will start getting hotter and hotter and become useless.

lol. so do tell what would happen to the Alu HS? :rolleyes:

That's why just looking at thermal conductivity doesn't tell the whole story. In a lab, yeah it does, but in real life it does not.

I sense... fail

An aluminum heatsink doesn't conduct as much, so its fans can remove the heat from the case without becoming overburdened.

repeat that ^ to urself a few times, till u realise what u have said....

You CANNOT expect a heatsink to cool well if you aren't removing that excess heat from the case. That's all I'm saying.

I fixed that sentence for u ;)

First off, yeah a copper heatsink will be removing more heat but at the cost of ambient temperature rising IF YOU DON'T HAVE GOOD AIR FLOW.

u say that like its a bad thing... we want/need the air surrounding/passing the HS to rise in temp - it lets us know we are being successful in transferring heat from HS to air :up:

don't have close to the perfect air flow you seem to think exists. Again, consumer PC's are not a lab. We don't live in a vacuum, figuratively speaking. I think you're applying absolute scientific laws in a chaotic environment without thinking outside the box and realizing that there are a few important factors that kill this naive thinking.

pfft. let me repeat it for u: Laws of Physics (in this case, thermal dynamics)
I'm afraid they apply all the time, everywhere, everyday
they are not askew just cause they have been proven in a lab.. air flow is air flow, 'perfect' or not - it will have the same affect, relative to its amount, so the Laws still apply, the formulas are still true, fair'n'square - the only thing that has changed are the numbers that are plugged in to their corresponding symbols, thus changing the answer, thats all..

...it's traumatizing.

the only thing traumatizing is the lack of knowledge displayed by a few pplz, esp. RE: Cu vs Al & thermal properties etc..



*unbelievable*

[ryboto]

I think you misunderstood him. Cause you're both saying the same thing.
Copper is better. You just have to have more airflow, to be able to notice the difference...

No, you really don't. Copper will conduct faster, at the same air flow rates. NotFred made a very good point here. The copper version will transfer the energy at a faster rate than Al, so it might increase the bulk/ambient air temperature, so to combat that, you raise fan speeds, but in reality, the same amount of energy is released using an Al heatsink, so at steady state your energy balance is the same regardless of heatsink. Either you have a warmer CPU, or you release the energy to the air at a higher rate, and increase your air temperature. You've reduced the resistance to heat transfer from the heat source, so you're cooling it more effectively.

[ryboto]

*unbelievable*

I think his lack of response to my posts suggest he might have seen the light, I just wish this was common knowledge among the community.

Wrong, it is also a function of the material. The air/material temperature delta also holds true, as you claim.

Sorry, I should have said 1000rpm instead of 1500rpm-- I was just making an example by saying "a super quiet fan (1500rpm MAX, which is far quieter than the 2800rpm fan that it comes with).. and I said that I was not sure exactly what the fan threshold would be where you would start *noticing* a difference between aluminum and copper. For really noticeable results, it would have to be in the generic 2000+rpm ballpark. It's like having 0.5 degree difference, which would be within the margin of error (of course, your term papers would not include the margin of error that comes with real-life testing that I have done for many years). If the difference is so slight at low fan rpm speeds, aluminum is the obvious choice since it's far more cost-efficient and much lighter. That's why aluminum is a god-send for fan-less heatsinks.

I think you misunderstood him. Cause you're both saying the same thing.

Thanks, Pyroe.. you said it all.

[Baron_Davis]

Lol sorry if I haven't seen YOUR light. Copper does STORE more heat at any point in time. Just because because the electrons move from one orbit to another doesn't mean they aren't IN ONE PLACE AT ONE TIME DURING THIS TRANSFER OF ENERGY. The one guy's long ass post is pretty crap. Only insecure people need to break down a post sentence by sentence to make themselves look special. You just look retarded imo anyway.

The point I have been making since the start is that THE COPPER TRANSFERS MORE HEAT FROM THE CPU. YES, IT'S OBVIOUS TO A CHILD THAT THE HEAT PRODUCED BY THE PROCESSOR IS THE SAME REGARDLESS OF HEATSINK, BUT THAT EXCESS HEAT THAT ISN'T TRANSFERRED BY LESS CONDUCTIVE MATERIALS SUCH AS ALUMINUM IS DISPERSED IN A CHAOTIC AND UNPREDICTABLE MANNER, TO LOCATIONS UNKNOWN TO USE SINCE NOBODY HERE HAS DONE TESTS TO SEE WHERE THE HEAT IS GOING. THE SAME HEAT BEING TRANSFERRED BY THE COPPER HEATSINK IS GOING IN THE CASE, RESULTING IN A POTENTIALLY HIGHER AMBIENT TEMPERATURE IF MORE POWERFUL FANS AREN'T PUSHING THE HEAT OUTSIDE THE CASE. THAT IS ALL I'M SAYING FFS.

Wrong, it is also a function of the material. The air/material temperature delta also holds true, as you claim.

I didn't say anything about the accuracy or error margins, whether or not copper outperforms Al outside a margin of error. I'm just saying based on Heat transfer, and the governing energy balance equations, heat transfer from a material to the air or fluid is not a direct function of the material, but a function of the properties of the fluid, and the driving force for heat transfer, temperature difference. If anything, this alone would make copper a better choice for passive heatsinks, or fanned heatsinks. The copper will be warmer because it has a higher thermal conductivity, the greater temperature difference will increase the rate of heat transfer to the air. I posted the governing equations earlier.

Considering the heatpipes are already copper, and they transfer heat incredibly fast, having thin copper fins vs thin aluminum fins for this specific heatsink might show hardly any difference. If you were comparing a finned block of cu vs al, the differences would probably be more noticeable.

Anyway, I don't think you understand what I was saying (or anyone else for that matter, seeing as how your grasp on the English language is total :banana::banana::banana::banana:), so it's not worth responding to you.

So that is your counter argument? At least I am willing to discuss this.

You are really saying that Alu works better than Cu? Why don't they use brass or cast iron instead? They must work SO well. :clap:

Ill just say that cooper cools better, in any aspect/condition. Unfortunately, the misconception is not dead yet...

[Baron_Davis]

There are a variety of materials in a case, and heat can be trapped which is why there is such a thing as hot spots. To think that because copper is a better thermal conductor automatically makes better cooling is foolish. It isn't that simple...

Ill just say that cooper cools better, in any aspect/condition. Unfortunately, the misconception is not dead yet...

Probably through the PCB, surrounded materials the chip is in contact with, etc, etc, etc.

If the Al won't wick away the heat fast enough from the CPU, it'll disperse with whatever else it is in contact with.

That makes total sense. Baron's point does make sense, though it's a bit .. confusing in presentation.

[ryboto]

There are a variety of materials in a case, and heat can be trapped which is why there is such a thing as hot spots. To think that because copper is a better thermal conductor automatically makes better cooling is foolish. It isn't that simple...

it is that simple. Copper is better at cooling a surface than Aluminum. That is what you were arguing against. Now you're modifying your argument to say that because copper allows for lower thermal resistance of heat transfer from the CPU it's heating the ambient air faster(true), and causing hot spots and this makes copper not as acceptable. Well, it's cooling the CPU better, and I really don't think it's going to be of the magnitude that we'll see even a 2-3C increase in case temps, unless of course you're trying to use this in an extremely quiet system, which I'm assuming no one will do.

[[XC] Lead Head]

If your CPU puts out 50 watts of heat, and say with a copper cooler it runs at 35*C, and with an aluminum it runs at 45*C, and those are steady temperatures, they don't increase at all after that point. 50 watts is 50 watts, whether it is at 35*C or 45*C. You put the copper cooler on the CPU, it simple is able to take the heat away from the CPU faster, but the same 50 watts of heat is still being dumped into the case from the aluminum heatsink.

There is no such thing as a free lunch. If 50 watts is being dissipated by the alu sink, 50 watts is going to be dissipated by the copper sink. With the copper sink you will get more cooler air, while with the alu sink you get less hotter air. It all works out the same in the end.

No, what happens with Al as opposed to Cu is that the rate of heat transfer is lower, so instead the CPU is hotter as a result. Sure, you'll have some heat transfer to the socket, and to other places, but the surface area for heat transfer in those directions are much much smaller, so their resistance to heat transfer is much much greater that they don't really do much in the grand scheme.

Yes, I got the point, I was just kiddin. He obviously knows that the "location" is inside the case lol. I understand that the real point is, "where" in the case.

Its an matter of heat distribution inside the case, since the heat source output the same watts regardless of the heatsink material.

With cooper, you get colder hot spots, therefore you get hotter surrounding air. This is ideal, it makes easier getting the heat out of the case by using fans.

With alu the inverse is true. More heat build up in the different materials, like the cpu itself, socket area etc, rather than surrounding air, so its harder to get the heat out of the case.

Yes, an better thermal conductor automatically makes better cooling. Its that simple. Colder hot spots, in detriment of surrounding air, is obviously better than the opposite.

My english is not the best, so dont take it too literally :)

You are totally off...show me one post where I said Aluminum is better than copper at transferring heat. What I've been saying all along is that with greater heat transfer comes the risk of greater ambient temps IF you don't have good fans (which HAS been my point all along...the need for powerful fans to offset copper's much great heat transferring ability).

Earlier you said-
That means that at any given time, it will be transferring and thus storing more heat energy than the aluminum version. Soooo that means that in order for the heatsink to not become overpowered by its own thermal conductivity, it needs to GET RID of the heat it conducts at a faster pace as well. Hence, the reason for more powerful fans.

You didn't mention anything about case fans, just a fan for the heatsink itself. Here's what I don't get, you're saying we should have higher speed case fans if we use Cu heatsinks, well, what happens if we use Al heatsinks? Should we need less airflow?

In reality, if you use Al, your CPU is warmer, so, you'd use a higher speed fan to force convection from the heatsink faster. You don't need to offset anything. How much of an increase in case temps do you think a copper version is going to give you?

I don't mean to put you on the spot, but looking through it seems like you've expanded and changed your initial stance on the subject.

This thread started out pretty badly anyway, with the 3kg claim and all.. I dont blame some of you guys since there were quite a number of review sites giving the wrong idea that aluminum fins cool better than copper fins.

Too much is being said on this thread, and not enough facts/numbers/statistics being shown. As Movieman said, only tests (benchmarks) will show the proof.

We could just look up the old comparisons of Thermalright's XP-90 vs. Xp-90c:

XP-90's weight: 360g
XP-90c's weight: 690g

(note: The copper version is not even twice the weight of the aluminum version.)

By looking at behardware's test, the aluminum XP-90 actually performs identically to the copper version when a low-speed fan is being used at o/c speeds, the delta temperature is 29.9 degrees for both versions, see: http://www.behardware.com/articles/568-17/test-25-cpu-coolers.html

[lawrywild]

Oh man this thread is packed full of fail.. the cpu heat goes to places "unknown" bahahaha!!

Alu dissapates heat to air better than copper? Umm no.

As ryboto said, the rate as which the heat transfers to the air is caused by the temperature delta between the ambient air and the heatsink, assuming others things constant like rate of airflow etc. It's complete bull:banana::banana::banana::banana: that aluminium does this better than copper and you're an idiot if you believe it. Copper is ALWAYS better than than aluminium for thermal and electrical applications, period.

What I've been saying all along is that with greater heat transfer comes the risk of greater ambient temps IF you don't have good fans (which HAS been my point all along...the need for powerful fans to offset copper's much great heat transferring ability).which is total bs
a 50W chip doesn't pump more heat into the case because you put a better cooler on it
the point you are implying about more heat being transferred to the PCB when you have a poorer heatsink doesn't change that

since the rate of heat transfer between air and a surface is dependant only on the rate of air-flow and temperature difference between the surface and the air i think if you were to say "the copper and aluminium heatsink versions would be the same temperature in the same conditions (same air flow, air temperature, and cpu load), but the temperature difference between the heatsink and CPU would be lower with the copper heatsink" you'd be 90% correct (there'd be slight differences, eg with the copper heatsink the base would be cooler due to the cooler CPU underneath, while the heat on the fins would be less concentrated around the heatpipes)

[NotFred]

Have we all completely ignored my post previously where I demonstrated that for a given power draw, and a given airflow, the ambient temperature inside the case is the same? No matter what cooling is going on inside the case.

The heat from the CPU cannot disappear into mysterious magical places; it all has to leave the case once the system is in steady state. The only way to do this is via the airflow (the case itself will never get hot enough to start radiating heat).

If anyone can point out the flaw in this argument I’d appreciate it…

[ryboto]

3) Conversely, if an aluminum heatsink is less thermally conductive, and it transfers LESS heat to the CPU area through the heatsink, where does the rest of the heat go? (this is a big one, if you feel faint, just let this one go and let the big boys take a stab at it)


If it's less thermally conductive, the surface it's cooling will become hotter, that's where the "heat" or heat energy goes.

Hot air moves up, you can not stop it. So yeah even with 0 airflow hot air will find a way to escape your case. These things are not air tight. BUT the question is how quick it does it? That's where airflow is getting in to play, if you got good airflow that warm air will go out the case faster thus lowering the overall temperature.

I agree with everything you just said, but fail to see how it invalidates anything I said. I was talking about a situation with constant case airflow (be it through fans moving air around or from air escaping out the top through convection). If you increase airflow then yes, case temperature and thus component temperature. will drop. This will affect things equally no matter what heat sink is being used however.

There are three ways to transfer thermal energy.


If there is a completely sealed case and components generating heat inside, the air inside will will heat. As the hot air goes up, the heat from the air transfers to the metal case because the casing metal is cooler than the air in the case. This then creates delta between the metallic case and the ambient room temperature. The bigger the delta is, the more heat is being transfered off from the case. Method like this, of course, is very inefficient when compared to a case coolers, but it works to a some degree. Better with hot components.

Well, as I said, the method is inefficient. But however, the case CAN heat up. It can burn your fingers. It can cause a fire in your room etc. Of course, the components would die before such an accident would happen, but nothing prevents that from happening if the components inside the sealed case generate enough heat. Enough being more than the case can radiate or conduct heat until the case temperature is high enough to e.g. start a fire.

Just a note for some people here:

If you have a isolated case, with 400 W(static, measured from the wall plug) "worth" (;)) of hardware, the ambient air in the room will be heated with 400 W, no matter how many fans or coolers it has. Same with water cooling. Same with peltier elements(as long as the 400 W is drawn from the wall.) Even if you had no fans, no coolers, 6 CPUs and 4 GFX cards with 64 GB of RAM and the system draws 400 W, it will not heat up the room any more or less than a single 400 W hair drier, or any other household item which draws the 400 W from the wall.

For some it seems that if you have a passive CPU heatsink(80C), it will heat the case more than a active(same heatsink with a fan attached) heatsink(45C) would. Same goes with GFX cards, unless the air is blown out of the case due to added fan/increased RPM. Some people keep thinking that if you have e.g. HD4850 with 15 % fan RPM and the card tops at 95C under load, it will heat the case more than it would with 100 % fan. Which is false(more RPM translates to more energy needed by the rotor of the fan, which means more heat).

After speaking to the guys downstairs about the cooler they have stated that in a few tests it has been a massive 10 degrees cooler than the standard TRUE 120 edition and about 7 degrees cooler than the TRUE 120 black edition cooler.

Therefore it does appear to be very good at cooling, but a bit on the heavy side which is causing them to stroke their chins and hum a lot

:shakes:

This is not true. A large majority of that 400W is converted to "work" (either mechanical or electrical). Inefficiency and resistance leads to heat generation, but it is nowhere near the full 400W that the system is drawing at the wall.

[Calmatory]

10C says nothing. Is it from 190C to 180C under -120C ambient?

The delta between ambient(case) temperature and the CPU temperature would help more. If the delta for TRUE is e.g. 33C, and this drops it to 23C..... :D :) Then again, if the delta is 95C and this drops it to 85C, then the performance increase isn't THAT remarkable.

Oh and for the hypocrites, and as you can see, my values are intended not to be practical, so don't even think about picking on that.

Work like what? Do you know what word "efficiency" means in this context?

Inefficiency? What does the energy turn into? Sound waves? Fotons which show up as a visible light inside the CPU core? :ROTF: Even if so, what does light turn into when it collides a solid object? Some of it will reflect, and the rest will turn into heat. Same goes with the sound. Everything turns into heat.

Even if the energy was stored as kinetic energy to the rotating blades of a fan, the rotating blades would cause friction inside the motor of the fan and some friction between the air and the surface of the blade. Some of the energy would be drained due to the air resistance, and that would make air move. Kinetic energy again. Which would later turn into heat thanks to the viscosity of air, friction again.

Here is something for you to think about: If not all of the 400 W goes to the heat, where does it go? Where does THAT energy store itself?

IF it is possible to store energy that way(in your opinion), please share! That would be major breaktrough.

[biohead]

it's only going to perform significantly better than its predecessor when the heat load is huge, passing the break-even point and then when awesome fans are used to remove that heat.

like the XP-90c. it's got potential due to it's capacity, but a great amount of airflow is a must.

obviously not a physics buff. heat is just one form of energy. a lot turns into heat eventually, of course, but your reasoning is flawed.

just consider the energy needed to ride a bicycle. if everything went into heat, how would you move forward?

Maybe I made it unclear a bit. But thats exactly what I am talking about. All the consumed energy will turn into heat. It will heat the room with the same amount of energy which is taken from the wall.

Well, you are right. I put it in a bad fashion. Of course, if the case is completely sealed and isolated, it will not necessarily heat the room with the 400 W at any given time, but eventually all the energy taken from the wall will turn into heat and thus the room will be heated with the same amount of energy.

Should be a tad more clear now. :)

That is the arguement you are trying to prove here. Work is always being done in any system.. This takes some % of the watts. Watts are a measure of work done over time.

Get a haircut too....

Oh the irony! You tell me to get a book, when you obviously haven't read yours.

If you do X amount of work, you will also eventually generate X amount of heat, no matter what. How is this different inside a sealed computer case?

You were talking about efficiency. Let's take a simple example: Take a 60W lightbulb and let it light your room. Now, the efficiency of the particular bulb is, let's say, 5,86 %. 5,86 % of the energy consumed is visible light. That would mean that (60*0.0586=)3.51 watts goes into visible light. Now, do you think that (60-3,51=)56.49 watts goes into heat and sound due to the bad efficiency? What happens to the light energy when it collides with something? Does it disapprear? Does it go somewhere we can't see? Under your bed? No. Some of it will reflect. Some of it will be absorbed by the matter it collides with. All that absorbed energy now turns into heat. Same happens with sound. When all the light the bulb emits eventually turns into heat, it means that all the energy consumed by the bulb indee
