So i was thinking of getting a peltier for my i5, or rather i did.
i work at an electronics store so i was able to get a couple 140watt peltiers for like 10 bucks each. of course it couldnt handle the OC 3570k (idle was fine, but load was lulz) so i put it back to stock and it was pretty cool, got me -5 to -10 C at idle, and load it got up to about 35-40C (i was using my true120 to cool it)

unfortunately i was playing with it late at night when i was tired, and was just planning to test it then shut it off before going to sleep (hadn't insulated anything yet) well i left it on over night, without keeping it under load (DOH!) and went to work the next morning without checking on it. get home and it wont come out of sleep..... oh . i remembered then that i had the peltier on it. so i shut everything down and take it apart to find a few drops of water in and around the socket (SONOFABISCUIT!) well, i replaced the motherboard (my z77 sabertooth, RIP, served me well) with an asrock xtreme 4. pretty nice board, once i updated the bios, the boot time which was bothering me shortened significantly.

anyways, the cpu is no longer prime stable at any clock, minimum 1, most often 2 cores fail while the other 2 or 3 keep on trucking. I'm fine with that though as it still runs my games and whatnot.

I had a h100i ready for the peltier, which im now using alone to cool the cpu. and my boss just ordered a couple 12v 29A power supplies im guessing i need around a 250-300watt unit (3570k @ 4.8-5ghz). (i plan to get a new cpu sooner or later)

so my questions are as follows:
does anyone know where to get a peltier of this wattage that is an appropriate size? i've found some that i think are like 55-65mm, im not sure if that's too big or not. but even if that would be a good physical size, the places i found them aren't for retail, and i dont need 100+ of them.
and will the h100i cool it and the cpu?
i've got liquid electrical tape that i plan to coat all around, inside (not the pins but the little pcb section) and behind the socket with, and i've got a mousepad i can cut up for neoprene, is there anything else i need for insulation?
