Question about peltier

post #1 of 6
Thread Starter 
Ok I just saw this: http://www.sidewindercomputers.com/pemo622212vd.html

From what little I know about peltier cooling (well peltier heat transfer)
says that I could just sandwich that between my cpu and block, power it up (of course adding condensation proofing) and viola.....

Am I right? I realize that was a very simple description but isn't that basically it?

That is the basic concept, yes. Make sure it faces the right way. lol

Yes - it will keep the CPU cooler, but then you will have to come up with a scheme to cool the hot side of the Pelltier device - add in the power you will have to drive through the Pelltier device, and you end up with spending a bunch of cash on the device, because you will still have to have a heatsink and fan for cooling.

Really, if it was that easy, they would do it, but the laws of thermodynamics limit such stuff to those environments where cooling can not be direct, like in hermetically sealed systems.

Right I wasn't sure if my MCR-320 rad would take that heat load wouldn't it?
I'd have the capacity to disapate enough heat using my current loop
though the question then is would the apogee gtz be able to transfer enough
heat away?

I also have a 400w psu I thought would easily power it....
This wasn't a serious idea, although had someone said yeah just through it in and hook it up in the right direction..... $25 isn't much to add to my loop and I wasn't expecting ridiculous temps but near ambient loads maybe....
Anyway thanks for the input

First of all, I doubt a 225W Qmax will be enough for an overclocked Q9550. Secondly that figure is rated at Umax 30v, and Im guesing that 400W PSU is a standard ATX PSU. Which will limit you to 12v, meaning Qmax will be substantially decreased.

You will need to purchase a coldplate and hotplate, that covers the entire TEC, and will require 150-300PSI.

You could use an eBay 545W TEC and undervolt to 12v.


These figure are rated at hotside of 27C, and I doubt a single 120.3 radiator can cool a heatload of 538W to anywhere near that.

I did that a year ago. Used a 226W TEC.
The problem was... One GTX360 rad. wasn't able to cool it, so... I doubt that Swiftech rad will do it
