OK, I think I know why my full load temps were so high (even tho I only have the Intel stock HSF)

My mobo is not allowing PWM to make my cpu fan run at 100%!

When I set the cpu fan speed control to disabled rather than auto... it runs at max speed, which is 2100 rpm or something.

35 minutes of Prime95 small fft gives me 78 degrees on core 0, occasionally it jumps to 80 for a few seconds. almost a 10 degrees improvement from before...

this is without adding any extra case fans(which my case does need!)

is this a problem with F10d BIOS??
