Zap, I think you might be correct. I did some searching on google and it looks like it is the NB temp, or at least it's supposed to be.
After testing it with some extra fans, I am pretty sure it has to be a faulty reading. I tried both a chipset fan and a 80mm case fan. both did little to change the temp. It still hovered aorund 92. The highest reading I've seen, even under full load, is 93C btw.
I also touched the heat sink with my finger, and it barely felt warm. Not hot at all.
I'm running a Antec 900, so air flow shuld be fine. And the rest of my temps are normal. 4 CPU's are reporting below 40 idle, GPU around 38, Case temp 26, and HD temp 25.
Here are a couple screen shots of the 80mm fan blowing air onto the heatsink. The room temp was pretty cool this morning too, around 60F. It was a cool night here in the mountains last night
I also added another screen shot of the temps, using cpuid HW monitor.

Now, one last question. In the off chance it is an accurate reading. I know its definitely hot, but how hot is too hot? From the little reading I did, it looks like most chipsets can hanlde higher temps, compared to CPU/GPU's, but shoud I be concerned if it's a true reading?
I guess the only other thing I could do, would be to install a better heatsink and or re-seat it with some better paste. in case the chip is not making a good connection with the heatsink
Thanks again for your help
