Thanks gotvoltage! I was thinking of modding the NB/PWM sink to accept a waterblock is all. Wasnt sure if it would be worth the trouble. Board does seem rather cool now prolly just leave it alone. Its great to be WC again for sure! Cant wait for a Calisto chip to torture!!! Question: Will my NB clock be determined by CPU or the board? IE will a new phenom 2 possibly give me more NB clock?
