Either the temp sensors are off, or they really do run this cool. Last night it was idling with CnQ at 21C. Played that FEAR demo and left HWMonitor running and it never got above 37C. Ambient is 20C. That's with the OEM HSF that has no heatpipes on it.

I was able to sorta get an old version of Overdrive working but I don't think it supports the Phenom II X3s very well, I couldn't change the multi on the 1st core, but i could sort on the 2 and 3... if i set it to 16, it would drop back to 15.5 when I clicked Apply.
