“After a day or two of complete stability I found it so much fun that I decided to remove the mainboard from the casing again and equip it with some watercooling to see how well it overclocked. I opted for Asetek watercooling as it’s high-performance and these Prescott based Pentium 4’s run ridiculously hot. With watercooling we where able to get the temperature in Degrees C below 50 at full processor utilization.
Overclocking was quite a weird experience. As within seconds we had a 3.6 GHz CPU running at 4.12 GHz… 100% Stable. We settled for 4 GHz though as we are including some results from our nForce 4 AMD 64 4000+ SLI test system and wanted to match performance as closely as possible.”
