I am extremely stable to 4GHz but I am not getting my work done for any more. My CPU temperature is 56C. I want to replace my Zalman fan and put a cooler on it (Titan Fenrir xmas) rpm is slower so I think another 120mm Fan might be needed. Goal is 4GHz stable overclock and I need to get 470FSB speed and currently I am having a 440FSB. any help to this would be really appreciated. Thank you in advance for your valuable suggestions.
