Any TEC Tutorials out there?

post #1 of 9
Thread Starter 
Hi, I was just browsing on frozencpu.com for parts that I am about to order next week and I've always been interested on Peltier plates.


I just don't know how exactly you make them work, I know one side gets cool while the other is hot and you need to cool down the hot side enough so that you don't mess things up, anyways I am not looking into a extreme peltier plate cooling but if if this 80watts peltier plate can make my CPU temps cooler than a straight up EK Supremacy block on my FX8350 lower, then why not?


I know these things may require quite the amount of power, my PSU is 1250watts, my system specs is as follows.

FX8350
Gigabyte 990FXA-UD3 rev. 1.1
XFX HD7970
Seasonic X1250
Corsair Vengeance 8Gb (2x4Gb) 1866Mhz
Corsair 128GB SSD



The CPU and GPU will be in a single loop, I don't know if the 80watts peltier plate would produce so much heat that it would affect my GPU temps dramatically, if so I would use 2 separate loops for them if I have to.


Things I want to know is from the very basics, how would it affect my temps and what improvement should I expect from straight up watercooling vs. w/ 80watts peltier plate.

and anything else that you guys think I need to know, and how to make them work properly. I believe I read somewhere that to take advantage of the full 80watts of the peltier plate you need to put it under 16v which is equivalent to 8pin power connector that can continuously supply 8.5amps, I don't really care if I only have to put it under 12v (4pin molex) power connector as long as it will still have big impact on temps vs straight up watercooling.



so just post away guys! give me the advices on how to make that peltier plate work, what to expect and whatnot. I am open to learn about this thing.

My rule of thumb is: to cool a given amount of CPU heat you need TECs with Qmax of about twice of that to be optimal.
Check this thread to get some idea:

You are right about that. TECs will significantly raise the loop temperature. It's better to use two loops.

Your idea won't work as it stands unfortunately. A peltier will only ever move as much heat as it's rated for. This means if your CPU has a heatload over 80watts, which it absolutely will at load on stock clocks, it will insulate all the rest of the heatload creating an ever escalating temperature until your CPU reaches its thermal failsafe and shuts down.

You need to move /at least/ as much heat as your CPU creates. As foxrena said for optimal performance you want a TEC that will move twice your intended heatload. An FX-8350 will have 120watt heatload at stock clocks and a 235watt heatload at a 5GHz overclock.


TECs aren't as simple as slap on a block and it will increase your performance.

And if you are going to just slap it on the block, you're gonna have to watch out for condensation issues.
Best thing to do is just make yourself a chiller setup and have your cpu AND gpu running nice and chilly.

Any idea about the wattage a 7950 GPU throws out?? I am curious if the idea would work on a GPU instead of a CPU???
post #7 of 9
I'd say between 150 and 250 depending how much loading you got on it.

The thermal design power of a 7970 is 230watts unoverclocked, so probably around 190-220watts. If I remember correctly the GPU is NOT voltage locked, so you can push it much further than that if you want. You want a TEC to move 200% the devices heatload for optimal efficiency. There's a thread up on the TEC forums about a 700Qmax peltier, so that may interest you if you're looking to make a TEC GPU watderblock.

While GPUs use a lot of wattage, they are easier to cool since the die is huge and the extra surface area makes it easy to pull heat off it.

This is why a crappy little H50 AIO can keep an overclocked 7970 in the 50s, but would have no chance against an overclocked IB with a MUCH higher heat density.
