This is exactly what i'm gonna do, but the hot plate's measure must be 11cm x 6cm, to have enough room for 2x OCZ blocks. Can you give me the depth of your cold plate?
@Chruschef: Of course i lap these block until they're flat.

11 cm ? 6cm ?
Each block is just over 11mm thick ... and the step is 5mm .. so total hight above components when measured from the motherborad* is 13mm
* assuming the top of the CPU is 8mm from the motherboard
im making a better block than what's pictured right this second if you'd like one
i just read back. ok you want it that large to fit to water blocks on ... i could make the hot plate 12cm long no problems .. it still need to be wider than 60mm though.. why / where does it need to be smaller
i came up with this in a minute ..would this work

As you can tell, we have run into a snag with our TEC vendor. The initial TEC I chose wasn't giving me satisfaction, so I spec'd another unit that can run at close to max efficiency on a 12v PSU. Problem is I am still waiting for the sample module...don't laugh! since this isn't a top priority, I haven't bugged my vendor on a daily basis as I usually do, and he slacked off. I'm back on it now, and hopefully should get the module soon so I can resume testing.
Sorry for the delay, and not posting updates. It's been quite busy around here lately!
yay updates finally!!!
It will have to be well over 250w. I have a 226 pelt hooked up to a 320-15 Meanwell. Just for grins I put in on my i7 920 overclocked to 4.0ghz under a really good water cooling system. As I was told to expect it promptly was overwhelmed by the heat of the 920. I had my alarms set at 75c and they went off at about 2 minutes and temps were still climbing rapidly. Without TEC the same water cooling holds temps at 4.0 to about 70c fully stressed.
If Gabe can come up with something at ~400 watts I will go for it. Much less and I don't think it will be worth it.
The problem is Gabe said he was looking for efficiency at 12v...
Well half the world thinks the efficiency point of a TEC is 75% max power which might indicate he is planning to use a 15.6v TEC. A 15.6v TEC is a 127 couple unit and there are some hefty ones about especially as it was hinted it was a custom unit. To be bigger than 275w at 75% power it will have to be at least 350w + Qcmax so it will be at the limits of 62mm 127 couple design I believe. You certainly wont get the 400w your looking for....well not in my estimation anyway - that's why I thought his original posting was very hard to believe. I think it was a brave thing to do to make an announcement like that when at that point he didn't even have a TEC to test let alone consider how he was going to power it- -I just hope that hasty decision does not impinge on his business too much !
He could be using a TEC with a higher couple number especially as it was hinted it was custom but the undervolting efficiency point is the COP efficiency point of around 30% max power but to get 275w at this point is just ridiculous. Not least the average Joe bloggs wil have difficulty getting the 20ºC delta needed to reach that efficiency anyway.
So he could use a TEC with a large couple number and carefully choose the undervolting to 12v but he will be a way off the so called "max efficiency" he was referring to. Besides I wouldn't to run a 400w TEC at a COP of 0.5 - 0.75 (which is what it will be in this scenario.) for any length of time not with the massive cooling system that be required with it.
So what was Gabe talking about ?
It really will be a magic TEC.....
To be honest I think single TEC direct die cooling has nearly had it's day due to todays high TDP's a multi-TEC cooler is a much better proposition - Coolit's offerings are about at their peak due to their use of molex connectors for power so all that remains really is self-builds - with too few people around who know enough about TEC's to implement it effectively.
i don't see why you'd want to run the TEC at 12volts anyway? i mean your gonna have to buy a new psu of this thing any way what difference does it make if it's a 12volt one or 24?
Hey guys, what thermal is the best for TEC? AS5 or AS ceramique?
Your quite right...but I am thinking his is concerned at the cost of a PSU to run his unit. He will sell more if he can keep the PSU cheap but as I already said unless his TEC can pack some oomph there will be a mighty lot of disappointed peps here. He may ultimately NEED to use a 24v supply.
It has been awfully quiet for a while now. Has anyone heard anything from Gabe. I would love to see an i7 strength TEC.
Well, besides the 15-20 folks who've read about this project here (and I hope everyone understands that it is in development), I doubt that there's much harm done. If anything, he was testing the water by announcing it and seeing what kind of response it would get :P
Besides, he stated that it wasn't a top priority anyway for his business hehe ;)
Now the real question is: Why not plan ahead for 32nm since core i7 cooler market is already well saturated? It seems like the best move would be to plan ahead for next gen and really look sharp when you can do a simultaneous launch.
I'm watching this thread now, as well. If a decent PSU and power requirements solution could be worked out, this could be interesting.
Gabe keeps rolling out the goodies. First the MCR420, now this. It's like christmas for overclockers.
I wouldn't be surprised if it actually happened, I've warned some large number of people about the PSU issue and I'm sure I havn't even skimmed the surface. I suppose if people wish to be stupid it is their right to do so.
1. You should probably check the output capacity of your 24V DC supply. For a 437W TEC, you will need at least a quality 400W DC PSU or better a 450W one. Also, use some meter thingy to ensure your TEC do indeed is draining 400+ wattage. (There might be also a small chance that you got an over marked TEC.)
2. Please also check the temperature on your TEC's hot side. From what you wrote, you may not have sufficient cooling on the hot side since you indeed, need to dissipate as much as 437W of heat.
The 437W TEC you used I am assuming it specs as 24V 18.2A, then the cooling capacity is 437 x 0.6 = 262.2W.
In order to produce 262.2W of heat, your Q6600 will absolutely need to use more than 262.2W electricity to produce that, since no chips would have 100% efficiency on heat conversion. (If so, we would probably use all those fail-to-meet spec chips from Intel/ AMD for very efficient heaters. It is just like if you have 1 lb of orange, you can never produce more than 1 lb of juice, please don't use the add water thing as a joke:P)
So how much electricity can your Q6600 use at 3.9 OC? Well, if referring to Intel's technical paper on core 2 quad processors (doc number 315592-005, table 2, 4) and ATX specs, if running your CPU at 1.6V (ouch), you will use at most around 325W electricity (which will never ever ever happen!) Consider 80% of that turned to heat, then your Q6600 ended up producing 260W of heat (TDP). What about the other 20%? Well, that's the computing power you gain, right? In reality, your Q6600 produce far less than 260W TDP.
From the look of your TEC's spec it should be able to handle your processor easily and should have achieve far lower temperature when system is loaded. With your TEC's hot side being cooled around 60C, you should be able to get near zero when full loaded.
Currently, assuming if you are truly able to dissipate 437W of heat successfully from the hot side, then according to your CPU's reading of 45C, with 60C delta added to TEC's hot side, that's 105C... It's just insane, something does not add up here. So please check 1 and 2 mentioned above.
On the other hand, I have checked ChillerZero's work log on the site he listed on his post (25+ pages, now he's into phase change cooling, lol) All his numbers and results looked very legit to me. He was close to find the holly grail, but he missed a number of important factors. Also, his post didn't provide enough data for analysis, especially room/ ambient temperature, TEC hot side temperature, TEC's actual specification (need label printed on the plate), his CPU's default voltage (when mobo posted w/o OC). But then, it will be too much for me to write, lol
DBC
Actually the 437w he's talking about is a 437w Qmax (50C) or 360w Qmax (27C) so we must be slightly careful about how we tackle this the PSU has to be closer to 700w to actually give the full 360w Qmax and even then you won't get the best performance of any TEC.
You are not exactly right, actually a 600W PSU can do 360 Qmax just fine with efficiency of 0.6. Now days, a 600W PSU can handle 600W or overload a bit I believe. Also, there's really no way you could find a TEC rated 16V with 527W Qmax (mountable on any CPU) from the post I quoted. So I believe the 437W he (Bond Number) referred to was power usage but not Qmax.
On the other hand though, it is absolutely possible to get a 24V DC PSU rated at 600W or even 1000W (just look for communication/ surveillance equipments). The only problem here is money... We could however though, pair up two 320W DC PSU together for 600W :shocked:, lol.
From my previous post, the point I was trying to make was, with ChillerZero's 24V 320W DC supply, at most Qmax he could pull is 192, and with that 192W, he was able to cool his i7-920 to near 30c full load w/ OC close to 4 ghz, so Gabe's proposal is DEFINITELY doable.
Lots people on this forum claiming i7 pulling 300W TDP OCed at 4 ghz is just way off the proportion. That's why I ran through Intel's tech paper and ATX spec for the actual answers (by looking at Vmax and Imax allowed).
In fact, an i7 OC to 4.7 ghz with 1.5V will generate at most 298W TDP, and 5.0 ghz with 1.6V will get 340W. So how many would actually hit 4.7 ghz or use 1.5V above?
DBC
Im still surprised that no one credible has tried a 62mm TEC on a i7 yet ?
In theory ChillerZero's results are impossible. But thats based on the CPU load calculators being correct. Which they may not be. So for me im still waiting for someone else to give it a try. I've got a 62mm TEC and water block pitty i dont have a i7 id be happy to sell it too
duckbillclinton, I suggest you read a bit more on TEC's before making claims you are unable to back up. A 360w Qmax TEC requires nearly 600w of power to run at 360 Qmax. Assuming the voltage is lower than Umax then you no longer get the full 360w Qmax. As muffy stated these results just don't make any sense.
Muffy is me by the way . i got the nick name from eating a muffin everyday for 5 years
BY THE WAY ChillerZero wasn't using a 62mm TEC he was using a 50 mm TEC ... hes said he was using a 226 watts of QMAX TEC. A 62mm TEC wouldn't have fitted his block anyway
Hey, bud, I did say on my post a 360W TEC will need 600W PSU. What I tried to say was we don't need 700W PSU, lol, since a 600W can overload a bit (+- 5 to 15% depending on spec). I do undertand lots TEC rated 24V is indeed 24.1V, and a 360W Qmax TEC will need 360/ 0.6 = 600W power. I have been working in far east for 3.5 years now, and yes, before I posted here, I made 2 phone calls to 2 TEC factories here and talked to their engineers (the sales people routed my calls since they can't handle my questions).
Please don't get me wrong, dude. You are the one that is cool enough to know one of the key factor for TEC cooling is power supply, but you need to really read through my posts, lol.
However, one thing that puzzles me on this forum is that even ChillerZero is so hardcore on extreme cooling (with his 20+ pages work log covering modded SwiftTec TEC cooling), lots still don't believe him, even there's no reasons he should scam on the screenies. In fact, i think both of us do know ChillerZero's biggest problem on his setup is him having a gimpy 320W PSU.
By the way, I do have a question for you though, does Qmax change base on temperature? How come you mentioned 437W Qmax (50c), and 360W Qmax (27C)? If the temperature does play a factor, isn't that suppose to go the other way around?
Peace,
DBC
lol, yes, the calculator you used is off. I had the same doubts as you at first, and that's why i went through all the trouble to dig through Intel's tech papers and ATX 2.2+ documents. With ChillerZero's gimpy 320W PSU, the most Qmax his TEC could do is 192W. So, it is actually more shocking to know a 192W Qmax tech could actually manage the heat produced from 4.0 ghz OC with full load.
DBC
Swiftech MCW7000-T the waterblock phantome:confused:
There's no doubt that a TEC will use more electricity to cool a load to 20c if it's hot side is 60 over 20 but that doesn't make our statements wrong.
Na, dude, what I meant is besides the simple and complicate answer of NOs, I need some reference for reading, as it is an unknown territory for me. :yepp: I am not saying anyone is wrong, but if i have doubts, i would seek answers. :) Could you give me more details on the 2 big NOs thing? Thanks
DBC
This is a great site
http://www.tetech.com/FAQ-Technical-Information.html#2
Here is a link to a TEC that's rated at 25c and 50c
http://www.tetech.com/temodules/grap...99-1.4-0.8.pdf
And as you can see we're 100% correct :)
good stuff, thanks! Now i need to print all these out and find me a pen and some papers for calculation, reading is always good.
By the way, I didn't really question the legitamacy on anyone's comments but merely was trying to discuss, but I guess the bad part about internet discussion is, words don't carry a tone with them, so it does sound awkward sometimes by just reading, lol.
You my find this of some serious use
http://www.overclock.net/peltiers-te...bout-tecs.html
oh and here's a calculator so you dont have to do the number . it's not perfect but it'll give you an idea
http://watercooling.co.nz/node/60
It certainly seems to me that you shouldn't have been commenting on ChillerZero system since you clearly dont know enough to make that judgement call ?
Well, to be honest, the part I don't know is temperature affecting Qc, and it has really not that much to do with ChillerZero's setup. Because the assumption i was taking is the hot side of TEC being properly cooled, and it is a fact seen from ChillerZero's MCW-6500 setup. Also, we did see his CPU temp was at -10c when idle, and the increased heat from full load changed the temp to 30c. Though I can not be 100% sure on his rig, but one thing I can be sure is i7's TDP since I digged through all the spec documents and did calculations on my own. The error margin I used was pretty high, and no matter how hard i tried to inflated the TDP number, an i7 shall never exceed 360W TDP running at 5 Ghz with 1.6V Vcore (for 360W TDP, the i7 will need to draw at least 360W electricity from ATX power supply, and it is unlikely). Those 2 numbers are already insanely high. So Gabe's proposal is legit given that if his MCW7000-T could really cool the hot side fast enough.
Also, regarding ChillerZero, we all saw is he's pretty hardcore now running to phase change cooling. So one thing we can assume is, it is unlikely he lied on the 226W (192W actual on 320W PSU) TEC cooling part. He used a not so powerful 50mm TEC on his MCW-6500 was just taking a blind shot, but somehow it worked, lol. However though, using a 50mm TEC by him is a pretty damn good choice. You know, one of the TEC factory I called in mainland here from China confirmed they have 50mm TECs that with 199 couples can do 24.1V with 28A, 675W, and that's a whooping 405W Qc converted. In conjunction with a 1000W PSU (i could only find 600W or 1000W, no in between), and if we could cool the TEC's hot side at 50s while full load (edit: it should be 30s, not 50s, giving if i7 pump out 200W heat, and TEC being 100% efficient at 405W), we might be to able to get sub zero. IMHO using 62mm TEC is not optimum, as the extra space not covering the CPU die went to waste (even with large copper plate). Smaller TEC and cold plate are always more effective, but the hot side will be harder to cool. On the other hand, the pity part though, is the factory i called won't sell it to me unless i order them in min quantity of 100, lol, bastards.
After all, like I said before, this whole original thread is Gabe announcing MCW-7000T block, and we all want to see if that's a dud, right? For me, i am a firm believer it will work:)
i personally have not debated whether or not gabe's block with the 360 will work .. i have no dobt it WILL work. im debating ChillerZero results.
However moving to the 360watts Qc TEC and lets say a load of 359watts with a hot side temp of 27c whats the ruff temp of the cold side ?
That will be up to the TEC's spec, and also it has something related to the stuff you sent me to read early. For now, TEC1 in general has a dT of 60-70C if running in full efficiency. So, I will say, if it's 100% efficient on the TEC, the cold side should be still close to 27C (edited here, i misread your post, my previous post was wrong on calc as well, with i7 pumping 200W TDP, and TEC being 405 Qc, with hot side being 30, not 50, we might get sub zero). The actual number will all depends. You can certainly point out i am wrong on the answer, but on the other hand, it seems to me that after so many rounds of our discussion today, you are still trying to discredit ChillerZero, but before you do that, at least check his worklog from the other site, then you will know he also tried another TEC with higher Qc with 2 large HSF with heatpipes, later he gave up and went to phase change cooling.
In addition, if you really want to prove CZ is wrong, setup your own rig with worklog like him, then we will see. I myself however, is planning to do some experiments on my own by year end, and that's why I called the TEC manufacturer. I also called a DC PSU manufacturer as well, and confirmed I can order a 24V 600W or 1000W PSU through one of its distributor. Also I found work shops that can do custom milling and laser cuts for my custom made water block. But this will all depend on my personal life, at this stage, I am not promising anything as PC cooling is just one of my hobby.
By the way, dude, this whole thing is not about CZ rig being legit or not, the problem is we had too much speculation on i7's TDP and no one really bother to find the real answer, and on some threads, some even questioned if Gabe's proposal is doable.
Oh i've read as much of his work log i can via google translation. I dont need to discredit him .. as i originally posted when he brought it up ether the TDP is wrong or he's for getting to tell us all something.
Your not helping him cos at every place you can you spout forth something thats not ture and your discrediting your self quite nicely which is not helping him.
Ie the answer to my question is the hot and cold side of the TEC is virtually the same temp it doesn't matter the size of the original TEC . All you have is 360 watts of Qc. Qc is the amount of heat that can be moved from the cold side of the TEC to the hot side to a delta of 0
SO if you load it with 359 then the temp of the cold and hot side will be virtually the same of 27c
So the answer to my question is not -33 its 27c ish. The Qmax of the TEC or the efficiency it's running at is irrelevant.
On the topic of efficiency you can't have something that's 100 efficient
Stop claim to know something when you clearly know nothing. you'd learn alot more if you just asked question instead if making up rubbish and posting it.
UMM as for me TECing stuff .. i have no problem with that.. i have a quad TEC water to water chiller under my desk and a Direct die 62mm TEC block
Both of which i made on MY CNC Milling machine .. i have plenty of detailed work logs . The Quad TEC chiller work log is at 26,346 view so far and my 62mm TEC block work log is up to 315 relevant posts so far.
You are right this whole debate we have been having has had nothing to do with Gabe or ChillerZero or their rigs .. it's about you posting rubbish claiming that it's right. It would be a dis-service to the TEC community as a whole to let it slid. Cos people like me will have to mop it up later.
So im trying to discredit you and i think i've done a pretty good job so far.
How can you possibly have a valid opinion about Gabe or ChillerZero systems when you CLEARLY DON'T KNOW ANYTHING ABOUT TEC ? Seem crazy to me ?
I ACTUALLY WANT TO HELP YOU which is why i've sent you those links
dude, no need to cry out, read my post on the edit time (5:37am US EST timezone versus your 5:54am EST). I corrected my mistake before your post. It's still near 27c, since (360 - 359)/ 360 * DT = aprox 0. I didn't cheat to catch my own error.
I did expect a flaming post from you crying out loud as soon as I realize I misread your post and made an obvious mistake. I am here to debate but not to make war.
If you do look into your post time versus my original post's edit time, and acknowledge I did get the answer right, then I would like to apologize for confusion caused and make peace. After all, you are a very knowledgebale person to be a friend. :) Also, FYI, i edited this post as well, because the words i used was a bit arrogant.
If you disagree, then this post should be the end of our discussion.
the problem was in fact that the two TRUE's with the copper plate didn't get the heat enough out from the TEC.
Or maybe try with a less power TEC, maybe 170w or so.
it was tested on a P4 955 extreme with has almost the same heat as a i7, + the P4 955 EX was overclocked to give more heat and see what the TEC was handling.
but the TRUE getting mega hot, they didn't get the heat away from the TEC.
And it's taken you 3 months to come up with that......hmmmm
This is pretty much a dead thread Duckbillclinton hasn't been back....after stirring up a hornets nest....
and Gabes new i7 cooler is no nearer appearing on the horizon...
Check dates before replying !!!
You all got me excited to go back to TEC for no reason.
????
Oh sorry..... chillerzero bought back up the i7 thread and you thought it was on....
No sorry about that...nothing haappening with the i7 yet.
Do you check this thread Gabe? It would be awesome if you could drop in here ant let us know what the status of this block is. I think there are quite a few excited at the possibilities, yet wary of the results. An update either way would be appreciated. If for some reason this block isn't going to be delivered, that information would be nice as well. I'm sure the community would understand if there were some technical or performance limitations. Don't keep us in the dark man! :D
Sorry guys, I spoke privately to a number of you but never officially updated this thread. I am sorry to report that I could not meet my goals with any of the TEC modules that I tried. The TDP of these quad cores is still too high for current TEC modules, and the results are not worth the energy expenditure. The solution would work fine for non-overcloked CPU's, but as soon as you increase the voltage and frequency, the performance curves intersect in favor of straight liquid cooling.
I am not giving up yet, as there might be upcoming technologies that could allow us to reach our goals, but for the time being, this project is shelved.
Alright. Thanks for the direct response Gabe.
So I suppose that would confirm something that some of us have already said for sometime....single TECs for direct die cooling has had it's day...the TDP's are too high...untill we have bigger TEcs but then you get a problem powering the things.
Only way forward on TECs is to build a chiller...
now i'm using Freezone Elite and a Eliminator chiller.
i got two new MadMouse Glaciator TCT's TEC units to play with to :
http://i50.tinypic.com/345ngaa.jpg
Ar top cool
They have a habit of periodically posting adds in forums
SO lest summariser both sized of the top cool discussion
Firstly we’ll take the issues that top cool cannot refute because they come from TEC manufactures secs
1 top cool units don’t use a heat spreader on both side of the TEC. This means that Top cool units aren’t applying even pressure to the TEC’s entire surface. Most of their surface has NO pressure.
Pressure is required to be applied to the entire surface of the TEC because magnetic forces are trying to push the TEC apart.
2top cool rates their units at 45- 50c hot side temps. They do this because increasing the hot side temp increases the achievable delta and watts moved. Which means their units look more powerful than what they are @ a more realistic 20-25c
Right now for practical issues
There is no condensation management / insulations os when the chiller goes sub dew point it’s gonna bet very wet
Their Chillers are very large for their cooling power
Given all the above their chillers aren’t cheap
FOR The Chiller
It has a patent
It’s pretty much the only chiller available
I've tried the 226W S775 TEC by Swiftech on both C0 and D0 chips. I can cope with heat being pumped out by the i7 @ 4.5Ghz in "normal" conditions nicely hitting no more than 40C while gaming but it can't cope with stress proggies such as Prime/LinX.
Here's a screenshot of my old 940 C0 that could barely do 4.2Ghz on air and 4.3Ghz on water with HT OFF. By the way could somebody tell me the heat output of an i7 at 4.5Ghz and say, 1.475V? That's what my D0 used to run at while being cooled by the 226W TEC.
By the way i fed the TEC 12V from PCI-E line (1000W Silverstone PSU) using my custom 6-pin cable. No probs with overheating wires.
http://img42.imageshack.us/img42/1512/tec2t.jpg
Your CPU is using about 246 watts in that pic which is why a 226Qmax TEC can't get the job done
it could be time to bin the swiftech toy and get a real TEC water block one that can take up to 660Qmax
http://thermo-electric-cooling.com/pic/50x2v2/50-8
Yeah i know but i'm not into ghetto stuff anymore.
Oh yeah and i ran a GTX480 at 900/2100 on the same loop.
no... we dont need to because he broke physics.
So either he's wrong.. or he has a very cold i7.
mmm... u really dont want ultra to go bye bye... next to uncle jimbo, ultra knows his stuff.
But i have to agree with ultra.. it didnt sound like you were asking him.. it sounded like you were trying to teach him.
Which is probably why he got mad.
But heres a long lesson i learned from all my years of tec research, and play.
1. They dont work unless u mass them.
2. They work a ton better when you run them at a lower voltage.
3. They work the best under water because of waters capacity to hold heat, and they work awesome when you mass them downvolted.
4. You are asking for it if you plug one into your psu molex. A power spike in your grid can mean it frying, even tho u dont feel it getting hot.
5. Mass them and down volt them.
Did i tell you, you need to mass them and downvolt them for them work real good? :X
LOL... piff.. only 4 TEC's??
*calling that dude who was gonna build that 80 tec system*
:P
Why you quoting duckbillclinton.....
He dissappeared off the scene ages ago and hasn't been back....
The glaciator from top cool here pi?ce of crap. I vive them away for Free to domebody for playing with them.
The best tec cooling solution i ever had is coolit boreas and freezone or home made tec coolers
