so i just bought 2 of these things cus they look cool and i wanted to play with them. however, i thought maybe i could do some decent cooling with them. i have an nzxt havik 140 and my temps are really low, but is it possible to hoook one of these things up to to my cpu and use that also. and is it possible to rig this on my gpu. i have a sapphire hd 7950 if that helps and an i5-3550
Just don't do it. I've done the math on it before in this forum. Basically what you do is create a heatsource in your PC with a TDP of the CPU's TDP + the energy that the Peltier element requires. You still have to cool the peltier element, and it will require more cooling than just the CPU.
