ever heard of this dual heatpipe cooler for the x1x00 series and 7x00 series?

:confused:

i did a search on google and only this came up:

http://www.aocusa.com/pview.php?g=PC...odel=EC-VC-RHC


second link has better pictures

the fan looks dinky but with a little modding maybe? :D too bad its out of stock or i'd give it a try for a mere 16.99usd


----------------------------------------------------edit--------------------------------------------------------

test results:

648/724.5 - 1.4/2.086/2.086/1.486 - AMD dual core X2 cpu cooler with two 80mm fans - 63c after ten mins of artifact scanning


648/724.5 - 1.4/2.086/2.086/1.486 - stock evercool - 80c after 3 mins and 35 secs of artifact scanning before i cancelled


648/724.5 - 1.4/2.086/2.086/1.486 - evercool with stock amd fan in the center - 76-77c after 10 mins of scanning


648/724.5 - 1.4/2.086/2.086/1.486 - evercool with two 80mm fans (same as ones used for stock amd x2 cooler) - 82c after 4 mins before i cancelled



mounting is not a variable because i did not have to unmount the cooler to change fans at all (used Arctic Silver 5)



my thoughts:

-fins actually get hot! unlike xp120 at 60c...this says something about how well the contact is between the fins and the heatpipes

-only thing that is transferring heat from base to the rest of the cooler are the two heat pipes, definitely not enough

-as previously said, it would be better if the cooler was attached to the base somehow rather than connected only through two pipes

-design could definitely be improved upon, but good idea for a universal cooler

-you lose the ability to use a heatsink on one memory module (see pic)

-supplied fan weak


finally someone (cantankerous) asked whether or not you can still use ramsinks, the answer is most likely yes, unless your sinks are one inch high

or taller. not sure? then look at the height of the red aluminum cooler that cools the power area...it shouldnt be taller than that if u want

them to fit. but i bolded the fact that you lose the ability to use a sink on one module because the heatpipes get in the way


conclusion: stick with the stock cooler with the fan at around 50 percent. then it will be better than this cooler cuz no modding is required and heat is exhausted out ur case. i'll try this cooler on my x700

later...see how well it fares on a card with lower heat output.

the cooler...as you can see its missing two heatpipes in the middle to save on costs i guess

hmm never seen one of those before, its definetly cheap enough to be a good modding project. would be cool to rip off the existing plastic and fan, and try to rig up a shroud with 2 80mm fans.

Yeah, I saw that before, you should search in the 3D Mark section, it was posted there long ago...

I wonder how this cooler will do as well. From the pic of the bottom of the cooler in the second link it looks pretty beefy in size. Should do quite well I would think but no one has tested it. It may have been out for awhile but compatibility must have just been approved as the X1800/X1900 cards are fairly new and arrived after this cooler hit the market. I am trying to find the best alternative on air over the stock cooler. If this is a candidate then bring it on! The more choices the better as right now we only have the Accelero X2 and the Zalman VF900.

found the actual product link:

http://www.evercool.com.tw/products/vc_rhc.htm

and here is a "review":

http://www.tech-mods.net/modules.php...wreview&id=174

pretty useless info in the review though...but useful for good pics of the cooler

i'd totally buy this and be the guinea pig...but i duno where to buy it from...lol

if someone finds it in stock i'll be the guinea pig (assuming from a reputable reseller)

Very kind of you chinkgai, someone hook him up, his help could be valuable to us all!

Subscribed.

Find that cooler! Looks awsome... :)

With a price like this, how could I refuse? :D

http://img.photobucket.com/albums/v2...XT/ordered.jpg

We'll know soon enough.

EDIT: Forgot ramsinks, oops. Can I get away without those at stock speeds? I wanna make sure the cooler's up to snuff before I order some of those.

nice! its in stock at newegg again! i ordered one too :D

Wow... so this isn't new?

I can't wait to see how well it works.......

OH ME EITHER! Thanks to you both who ordered, looking very forward to results. If they are good I have to find one in Canada. The X2 is out now in Canada but I think I will hold off to see how this does first.

... upon checking the evercool page it seems this this is very easy to mount, maybe a little too easy lol. Should be done in a matter of minutes with the application of the thermal paste takign the most amount of time.

PITCH D is what we need for the latest ATI offerings.

http://www.evercool.com.tw/install/instal_vcrhc.htm

It says for X1800 cards though with the PCB and mounting holes being the same for the X1900 as the X1800 it should pose no issues at all. I think it will just be a matter of time before evercool updates their page with the X1900 as being compatible. I am surprised there are no other reviews on this cooler, even if on other cards. Could this be the XP-120 for VGA cards?

I am just curious on the noise, it says 80mm at 2000rpm but says nothing about the noise factor, I hope its quiet. Better cooling is one thing but I also want a much quieter fan.

For the guys who do get this cooler, check and see how much clearance there is for ramsinks since this comes with none. It would be nice to know if some ramsinks are going to be uncompatible with this cooler due to height restraints. If any sinks will do what is recommended do you think as best? The Swiftech ones?

funny, i said this the other day to my buddy when i linked him to the cooler...:toast:

lets hope.

as for ur other questions, i'll try to address them and snap a pic or two when i receive it.

i might also test stock fan vs modded fan (80mm fan probably) depending on how anxious i am...lol

i'll compare all that to stock ati hsf temps (from memory cuz im not putting that damn thing on again) lol

and also to temps received from this mod:
http://www.xtremesystems.org/forums/...ad.php?t=90888

cuz i did that mod already also :p:

Chinkgai:
The egg's got Step 5 on mine. Being in Phoenix, I should recieve Fri or Sat. How bout you?

step 5 as well for me..i ordered three hours ago :toast:

i might be a bit closer than u...im in california :D

but, i'll bet we both get it the same day. (lets shoot for friday!!)

sounds great, thanks.

You better get that sucker on the hot seat ASAP! I'm can't wait to see if this is a viable solution to that evil sonic assault my poor ears are being violated with right now. :woot:

Hey guys what do you think of new Zalman passive cooler ?

http://www.xbitlabs.com/images/edito...P1020651_s.jpghttp://www.xbitlabs.com/images/edito...P1020645_s.jpg

Might be very interesting with decent fan on it. But it`s ment for 7600 cards. Don`t know if it will fit R520/R580/G71 cards

if you look real close at those pictures, you'll see the cooler after a minute or two :D

freal tho. that thing looks humonstrous and i'd buy that to test too if it fit and was available ;)

got a model name? (the cooler, not the chicks)

i would be very pleased if i got my hands on one fo those chick to test ;)

but really with modern vga cards i won't trust any fanless solution anymore

Hehe. You know what?
It's not the XP120 for GFX. It's the Big Typhoon for GFX :D
Take a look at the sleeving on the fan connector..

I like the girls on the background better :slap:

Reminds me of the 7800GTX 512 / 7900GTX stock HSF without the fan

Look at the pics of the zalman. It is NOT installable :slap:

What do you mean :confused:

1 no spot for a fan, so what? Ghetto mod it
2 screws not obvious, but they must be there

Wow, those are some nice pics x-bit has, hehe.

PHOENIX, AZ, US 03/16/2006 1:11 P.M. ARRIVAL SCAN

Well Carlz0r saw what i meant. And sure got a valid point.
But what i meant was that the heatsinkis langer towards the back than the card itself.

Could care less about the coolers i like the girl on the right that is holding it up lol....

Dragon

need more pics of chics and hardware. Boy if a magazine ever started...

just got the cooler and ripped it open.

kind of disappointed at the quality and design.

will post more after some testing.

Good idea! Lets team up and do it!

Well what do expect for only around $20? Results?

let us just wait and see what is said. I may do alright still. It is kinda late and I was hoping for results but I will be patient till the morning. Another site said it wasn't too bad in terms of build quality and performance so we will see.

Thanks again chinkgai for your testing on this.

Grrr, sorry to vent so much, but now UPS can't tell me why it wasn't delivered. They can't tell me why it was rescheduled. And they can't tell me where the hell it is?!

Oh I just hate being at the mercy of other people...

Can we just get a bunch of hot chics and buy an island? The xTreme iSland...that sounds nice.

I am in but if only there will be lots and lots of Quad 7900GTx and qaud cpu mobos and so on :), no need for chicks then

lol

updated OP with results and pics

looks good :)

Booo...so I should just refuse shipment lol!

man, not looking good. Up to 80c before you stopped it. I wonder what it would get too if you left it going? Was this witht he fan set to 100% via ATITool or overclocker utility? I am not insulting your testing just thought maybe you might have left it on default fan speed with 100% bringing better results. Switching the fan may bring better results but with it more noise. It seems the Accelero X2 is still better in this case. It too doesn't exhaust air out of the case but it is DEAD silent and still seems to keep temps around mid 70's which isn't too bad. The only other choice is the Zalman VF900 which I am still waiting for results on how it does on the X1900XTX. If not I guess I have no choice but to get the Accelero as I want to stick with air. I am not liking how one ram chip can't be cooled either. It will be that one chip that will die over time bringing the whole card down.

I appreciate greatly the time and money you put into testing this chinkgai, it is too bad it didn't turn out better. The fact that the fins get very hot means the cooler is working but still not enough for the high heat output of the X1900 cards. I am sure it will be fantastic for the X700. I think if they didn't remove 2 of the heatpipes it would bring temps down to the 70C for sure. I would have gladly payed a little more coin for that.

http://img65.imageshack.us/img65/4899/dsc000437wi.jpg

Just 2 long machine screws 2 wide body washers and to nuts would do the job. Is this 92 or 120mm??


I would go all the way with a thin 120mmx28mm fan

I'll just throw down my opinion here.

There is probably a significant problem with appropriate airflow on the the fan mods. The 2 blocks of fins that immediately surround the heatpipes hardly get any airflow except for the dual 80mm, and that's only a small portion.

To maximize airflow, I'd probably go with 2x80's, but mount them right above the fin blocks, or at angles to direct the flow mostly thru the 2 blocks. I'd also consider the suck position to avoid high back pressure from the video card surface.

If you want to go with a single center fan, you should cut away the fan housing and use the shroud.

Does seem like somewhat disappointing results for a fairly good idea. I think it wouldn't be a problem that the main block is only connected to the fins via heatpipes, if they used 4 heatpipes. But they didn't.

Not sure why companies are so shy about making big coolers. I think a fair number of folks would be happy to have a quiet high performance exhaust video card cooling solution that would occupy 3 extra slots (leaving 2 slots open for a sound card and one spare). Yes, it won't work for SLI configurations, but I doubt this one would either.

can we get clear pics of all 4 corners please :toast:

Yes! Yes! Yes!

Down with itty bitty coolers on the BEST cards! They get hot! No one likes the noise, haha.

pedophile?

yes, all the fans: the stock one, amd one, and two 80mm fans were all running at 100% so good observation cantank...if the stock fan was left at default...it'd most likely lock up cuz of heat

why did u leave it at 100%? cuz the connector it comes with does not fit on the connector on the card itself...so i plugged it in elsewhere

eastcoast...what do u mean two longs screws? i dont understand your point for saying what you said and quoting that picture?

navig, if i did what you suggested, the flow is still not enough to remove the high amount of heat...unless u increase the flow significantly...but then it wont be quiet or even near quiet anymore. the pipes were very very hot to touch. it just needs to be dispersed with more heatpipes.


as for testing with the x700...works superb! no pics...but i'll jes give u a quick result:

x700pro with ghetto 9800 pro heatsink - 59c after 15 min of scanning with atitool
x700pro with evercool left in stock form (100%fan) - 46c after 15 min and 48c after 30 hr cuz the case got heated up i guess

A) If you told me I'd want to @#$% a video card cooler yesterday, I'd of told you your nutz.... COUGH the one on the right COUGH.

The heatpipes are upside down. The fins need to be on the bback of the card, have the pipes come out and around the otherside, and then it would be designed correctly.

Heat pipe works by boiling water on the core, the steam rises to the fins, condenses, and the water rolls back down hill to the core, to be boiled again.

If the core is HIGHER than the fin end of the pipe, the water will settle in the lower cooler end of the pipe, and its effectiveness will be reduced.

We need a 4 copper pipe cooler, which runs the pipes up with a 90degree bend at the top of the card, and the fin section would then sit straight up in the case, with a fan on it...or door fan blowing across it, or sucking air through the fins out of the case.

If you know what I mean. Then the pipes would work 100% and all the geometry would be correct.

BTW, I did a ghetto mod, took the fan section off the stock cooler, used a mod'd 60mm-to-80mm fan adapter, which I glued onto the stock cooler, alowing me to mount a 80mm fan directly where the stock buzzsaw fan sat.

Much quieter, 66C max load at 657/725.... cost $10.

You probably don`t know exact heatpipe structure and thermodynamics in it.
btw I don`t think there`s water in the pipes (maybe i`m wrong) but it`d be more efficient to use liquids with lower boiling point.
But I agree that it should have 4 heatpipes like stock NV GTX cooler

Can we get a pick of that? I wonder how well that might work for me...

Ill take a pic Jod, post it here tommorrow.

On the fluid, most use water but manufacture the tubes in a low pressure atmosphre, so the inside of the tube is at a much lower pressure and the water boils at 100F instead of 212F. Makes for a very cheap solution.

The water molecules in the pipe can reach supersonic speeds moving from liquid to steam and back.

But given the stock Opteron heatpipe cooler is a 4pipe, I think 2 pipes for a much hotter core (GPU) warrents 4 pipes.

On my solution, I know its working well, the flow out of the fan (I have it rigged to suck air through the sink like the stock fan) feels like a blowtorch its so hot. So the stock sink is very efficient at etting the heat from the core, just needs a better flow of air than the stock buzzsaw fan provides.

the stock X1900 heatsink IS also a heatpipe... when you disassemble it, you find 2 pipes built into it.

Well I finally gave up on waiting for my cooler, so I picked up the Tide Water from Fry's today. For $100 bucks I get my silence back. It's completely silent and a run through 3d2k5 gets me 61c. Previously I had 83c with stock fan @ 50% and it was highly annoying.

Not sure if I'll keep it tho...since I'm highly excited about pursuing other H2O stuffs now. :p

Most modern heatpipes have wicking in them and so are not affected by gravity. I think most are using hydrocarbon chain refrigerants.

I've got some squirrel cage blowers here which I could slap onto it. But with such poor performance, its probably not worth the money.

the bad thing about using the stock sink with an 80mm fan like uwackme did is that you are stuck using those stock thermal pads as well...which are teh suck!! i have no idea why ati chose to use such garbage...

strap the stock amd hsf on there, its way better than stock and will allow you to use ramsinks as well.

I don't have access to the newer AMD coolers so I think I am just going to get the Accelero X2 this week. The main dilema now is whether I should use AS5 or Ceramique. I am usually a ceramique guy, especially when it comes to video cards but with the X1900 running as hot as it does im desperate for every last temperature drop even if very minor. If one of the pastes will do better than the other I will use that.

Never seen a definitive difference. There's probably more variance in batch to batch of either product than between the two. I use both.

navig

ok thanks, I may stick with ceramique then cause its non conductive.

I think they use pads cuz it's easier to get contact with the core if you don't have to machine the thing to have contact with RAM too. The pads fix up tolerance concerns. My Arctic Cooling ATI Silencer for my X850 uses them too. The metal plate in contact with the RAM still gets plenty warm, so it's obviously transfering heat a bit.

I was wondering if we could eliminate the pads and just use a glob of ceramique instead.

nope...it'll require too much for contact and then it'll jes overflow over the edges when heated up...gap is just too big

ok, thanks for the clear up. I assumed that but don't have the actual unit in my hands to see for myself. I hope to get my X2 by Wed. or Thurs. of this week.

hmmmm, whats the cheapest 'air cooler' that is out there that'll be an improvement for my old computers 6800GT (AGP)???

i was talking about the stock cooler, i have no idea about the accelero's gap size

probably not much different I am assuming.

There's a guy who just stuck an Accelero on his X1900XT. Trying to more infos from him now. Join the fight HERE!

Refusing my shipment put a big fat smile on my face, hehe. They even stuck it in my tracker notes:

thanks for the link on the accelero installation. Much appreciated.

Mine came in today. The only complaint I have is the location of the heatpips; they block off two of my ram chips so I cant put sinks on them. The cpu core temp dropped considerably though; from 65c full load to 47c.
