I have an XP1500 at 1.33Ghz overclocked to 1.64Ghz and have heard it will go faster. I have Artic Silver 3 on the CPU along with a Thermoengine Cooler. Using an IWILL-KK266+R Mobo and have the CPU running at 1.85v.
I think that the thermoengine is an excellent HS w/ that fan.
I was hitting 35c under full load (Prime95 running over 7hours)
w/ the same HSF until I tired of the fan's noise.
How much lower does his cpu temp need to be in order to his speed go faster and by how much?
