You guys are NOT going to believe this!!!!
My Clawhammer (A64 3200+) normally runs at 37C (99F) under full load.
While working with the BIOS, I accidentially enabled Q-fan without installing the driver.
The CPU temp rose to 130F and was running at that temp for at least 30 minutes without even flinching. I disabled Q-fan in the BIOS until I could find the driver (which turns the fan back up to normal speed) and the temp immediately came back to where it belongs...
I KNOW my P4 would FRY if it went that up 40+F for that long...
Thank God for AMD!
