I recently heard of something called a "peltier unit" (give it a quick google if you don't know what one is)


I have considered buying one just for messing about with, then I thought "what if I was to put one between my CPU and heatsink (with a bit of modification).

Considering one side gets to -17 celcius when exposed to air it could keep your CPU very cool when under load. They are very in efficient so your heatsink would get very hot.

Was just wondering what everyone thinks about this idea???
 
My first impression is that switching from very cold to even warm, or having both close to each other, would cause condensation, which wouldnt be good.
 
Peltier cooling is generally a pain and inefficient. It's best used in high-end watercooling.

What CPU are you cooling? You'll need to consider the CPU's TDP and the wattage of the peltier and being able to get rid of that heat. If you've only just stumbled across peltiers and aren't experienced in high-end cooling then i would advise you to read up on people's successes and those the have failed miserably before turning around walking away from the idea.

Peltiers were quite popular in overclocking circles about 15 years ago. The drawbacks outweigh the advantages hence why big air coolers and water is more common.
 
High end watercooling is a real must for cooling TEC setups , i use to have 2 x 172w tecs & i had to cope with cooling 500w+.
I used an ECT (evaporative cooling tower) to keep my temps under control ,
was a huge project , killed a number of CPU's before getting everything sorted but not really practical @ all but really absorbing to get it right.
 
Used to love my Peltier back in the days when AMd heat was a huge issue, but to be honest air and water cooling is a lot better now and CPUs are much more tolerant to high temps now.

Seriously not worth the effort any more unless you're experienced and just like the challenge.
 
Perhaps if you put your PC in the fridge?

I would strongly advise to stay away from peltiers. As has been said they were popular when it was acceptable to cover motherboards in dielectric grease, when we used pond pumps and chevy heatercores and bongs and all manner of nonsense. Just don't - even for kicks.
 
I haven't even seen a TEC for sale in the past few years, never mind TEC blocks etc. They've fallen out of usage for good reason. I remember a mate who had an 80w (modest) TEC on his ATI 9800 and the effect on his WC loop and room temp was astounding, though his GPU core was very cold, he was practically sat in his pants in winter :p
