ok so ive been looking into thermoelectric cooling. from what i have found out if a cpu runs at 100w the tec needs to be at least 100w aswell to cool it adequately. now would placing a 100w tec between a core2duo and a hsf of sufficient size be viable. the tec would be connected to a variable resistor and then to the psu's 12v rail.
does anybody have any knowledge relating to this sort of thing?
 
A air cooled heatsink won't likely cope with the heat output of both the CPU and the TEC. Also the VR will need to cope with upto 100W output as well, depending on the level of trimming back you go for.
 
You need to cool the CPU with the Pelt then cool the Pelt plus the CPU load. Unless you have a really powerful PSU you should use a dedicated PSU such as a Meanwell. A HSF will be no where near adequate. You will need at least a PA120.2 size rad and some powerful fans. Have a look in the advanced overclocking sticky. Any more Q's let me know. I had a play around with Jokesters pelt a few years ago. Never thought I could get a PA120.3 with 6 fans to run hot! :eek:

Edit: Speak of the devil.
 
thanks guys, i guess untill i get some spare money this idea has been crushed.

ive just been looking at the freezone tec cooler and it appears to use 6 tecs cooled by one central hsf, how is this achievable when with my idea 1 tec needs a 120.3 rad to cool it?

Good advice - Although the threads are somewhat outdated. you will see that modern cpu's arent really suited to this sort of cooling anymore - but some users have successfully managed some good results. Good water-cooling will almost always equal or out-perform pelts. The size of an adequate pelt wont fit over a modern CPU which leaves cascading smaller ones - a subject all of its own...
 
How so? It's completely inappropriate for your processor, that doesn't mean it shouldn't be for sale.

Peltiers are difficult to use. I don't think you've done any research into them based on your posts here. You have to deal with considerably more heat load than with conventional water cooling and provide a adequate current source to drive them. Control circuitry is a challenge unto itself, a variable resistor is not sufficient.

If you're looking for better cooling than air, you want water. You don't want to attempt air cooled peltiers.

The only viable use for peltiers I've been able to come up with so far is building a chiller based on them, and running below ambient water through an otherwise conventional cooling loop. The days of putting one directly between cpu and waterblock are behind us, though a means of mounting four or so pelts (not stacked) directly above the cpu socket may have potential.

If you're not dissuaded by any of this, read this handbook. It's from a thermoelectrics manufacturer and contains a lot of good information.

Using pelts in a water cooling setup is possible/reasonable from what I've read....and believe me I've read quite a bit.
I'm put off pelts for direct cooling and/but I like to understand things so I've got ideas of trying to use them for a chilled setup. You might find that a modded chiller unit will be far more effective and cheaper.
