Whats a healthy PWM temp I should see with my q6600 at idle and load?
Taken from the offical IP35-E thread just a few threads down is what I posted a few days ago...
----------
Q6600 @ 3.2Ghz (400x8 1.312v) Hottest CPU Core = 80c, PWM = 77c
PIC
E6750 @ 3.6Ghz (450x8 1.46v) Hottest CPU Core = 56c, PWM = 54c
PIC
A delta of 23c and according to your previous posts, the B3 Q6600 increase PWM temps ~20c. So, really, it was
not any better with a DC considering that less wattage is running through it.
So the logical conclusion that I have a 'bum' B3 isn't so logical. Lets be sure to compare apples to apples here. A Q6600 B3 is not a 'bum' chip, it is an older stepping. So, if my particular B3 were not within the ~20c delta, then I would agree that my chip is 'bum'. But this is clearly not the case as my B3 is responding as it should.
For those wondering, my current temps @ 3.33Ghz @ 1.35v is ~70c at hottest core and ~80c PWM.
For those wondering, even at 80c the board is perfectly safe for use. The motherboards threshold for warning is 100c and shutdown occours at 120c. The motherboard can handle these temperatures, I just don't particular like them.

I just finished the heatpipe mod and temps are indeed lower, particularly the PWM which feel from almost 90C after 30 mins of Prime95 to 78C. I have 2 40mm fans blowing on the PWM and Northbridge.[IP35Pro + QC 3.4]

Let me guess, you're OCing a Pentium D processor.
PWM is a reflection of how much power you are using for your motherboard. As we both know, the Pentium Dual Cores can eat up more than 250W especially when overclocked and overvolted thus the high PWM. People overclocking 5XX and 6XX wouldn't have temps above 50C.
To put it in perpective, the PWM mosfets/chips should handle temps up to 150C so yours is not a big problem.

On first glance, it would appear the PWM temps are out of control. That is not really the case here, the PWM is safe to temperatures in excess of 100C
I don't plan on spending anymore time discussing the PWM temperature, but these should be enough evidence that high temperatures are not rare and abnormal and the MOSFETs run hot depending on how much wattage is running through them.
