PWM Reading On ABit IP35 Pro in uGuru Very High!!!

[lettuce]

Am in the process of OC my Q6600 am at 3.4GHz with 1.4250 volts at the moment, but looking at uGuru readings its saying:

CPU 56c
SYS 26c
PWM 90c!!!!!

What is PWM and my is the temp so high, after 12 minutes of Prime95, is uGuru reading the temps correctly??

I am running Prime95 though as im overclocking atm, guess that would add to the heat?

Strange, i open my case up to change the fan i had on my heatsink, and i pushed the spring load bolts down and few times on all the heatsinks on the heatpipe, and now under load im getting a read of 75c. I have been lowering the volts on the cpu though which is right next to it, so its either that or the higher rpm fan ive suck on the heatsink now or both
