oh my god pelts are badass!! My friend and I put one on my GF3 Ti200 about a year back and ran it at 280MHz (the stock speed was 175).

Anyway yeah, it was watercooled, you pretty much need watercooling because pelts don't JUST move the heat from one side to the other, they add a lot of heat of their own. They're only about 30-40% efficient. So a 70W peltier will move 70W and add like 100W to the hot side. Yowza. Actually I don't remember the numbers, I might be pulling those out of my *** so don't quote me... Anyway peltiers rule if you can handle them
