Experimenting with TEC cooling for research project at university...

post #1 of 9
Thread Starter 
As stated in title, I will be experimenting with TEC cooling of cpu's for my physics research project this semester, as well as air/water cooling setups, given I can attain the proper equipment.

Any suggestions/ideas/tips that you guys might have about this?

Also, any suggestions on the best way to set up a TEC setup, provided I don't have access to equipment to machine specialized copper blocks?


Thanks for anything and everything!

What you are trying to cool and what's your goal?
If it's not much thermal load, you can use a large CPU water block, and a 50mm TEC (plus a cold plate).

The cpu I will be cooling is a C2Q Q6600 at stock frequency.

I've been provided with 3 50mm TEC's, each with a Qmax of 77 watts. I also have access to many power supplies with manual voltage and current controls, plenty enough to power the TECs.

those peltier units are way to weak to use for direct die cooling. You'll either need to buy a stronger unit or make a chiller out of them basically what most people do here is put a peltier between a cpu and waterblock to cool the cpu. You can only fit a single peltier between the cpu and waterblock so it needs to remove at least heat than the cpu is generating in order to cool it or else the temp of the coldside will keep climbing until your cpu begins throttling or goes into thermal shutdown failsafe.

If it's at the stock frequency I think it's fine. Obviously to use 3 50mm TECs a chiller or something equivalent have to be used.

The CPUs thermal design power is 105w

Dunno but demonstrating the cpu being cold @idle and it overheating at full power might make a cool project for a college presentation but realistically speaking he'll probably need a better tec to make it handle the heat under load.

Stack all 3 under a water block like a boss.




















Just kidding biggrin.gif. Make a 3x50mm chiller with all three of them and don't bother using one as direct die. They are too weak individually to be separated.

I'll see what I can do.

I'll probably to one direct die as an example of being underpowered for the job and just to see what happens.

Then will try and do all 3 chilling water.. If I can get the equipment to do it from the department. Which may not happen.



For the direct die option, do you think I will need to insulate and protect the board?

Unless you have a auto adjusting controller always insulate, problem is the CPU generates very little heat at idle, so the TEC may dip down below dewpoint on idle, water condenses on the mobo and cpu and bam, sparks smoke and lost money. wink.gif
