GN90 check out this video guys, AMD phenom II broke the record when it was overclocked to 7.08GHz using massive amount of watercooling http://www.youtube.com/watch?v=z6Hf6d404QY&feature=player_embedded
Xsever I know they let it get to -190 C before they start benchmarking. Some videos show you the temperature sensor with similar numbers as they are running the benchmarks.
J4D at one point i wanted to make a watercooling system but now i use a laptop , any donors ? i would be glad to make one for any pc
