Hey Laserspewpew - your name looks familiar. Do you play CSS on DOP Hightimes? As for your temps, they look a little high. Are you using stock cooling? I just built a Q6600 PC and I used a Thermalright Ultra extreme 120 heatsink. My idle temps are approximately 42 c on all 4 cores using Core Temp with an ambient of 26 c. I tried Speed Fan but the reported temps were approx. 15 c less than what Core Temp reported. I have heard that there is a 15 c margin using Speed Fan to report Q6600 temps. I am running XP 64 and Core Temp works fine so it might also work in Vista. Another good program is Everest. See you on HighTimes.
Hit control-alt-delete and bring up the "Task Manager"..take a look at the CPU usage, just to make sure you have no problems with any program running in a loop, as that will increase CPU usage, and drive higher temps..you might also try reseating the CPU heatsink...also, what is the ambient room temperature where your computer is? Goodluck
