Faulty CPU temp monitor?

My E5200 box, which I've moved to media PC duties after 'upgrading' to an PhII X4, has gotten a new CPU, an E7500. As both CPUs are 45nm, I didn't anticipate any issues, and indeed, it seems to be working well, aside from one oddity.

When I boot, it gives an error about the cpu fan and cpu temp, I have to hit F1 to 'resume', and then it boots (Vista Ultimate x86). I've run Speedfan and Asus PC-Probe, and both report a CPU temp of 100c exactly, with no change either at idle or running benches. The cpu cooler feels firmly attached, no wiggle, and it's one of the Cooler Master tower heatpipe coolers with those stupid push-pins. All 4 push-pins have fully extended and latched into the board evenly. I am using some AS5, the usual amount. The E5200 @ 3.15ghz was reporting temps in the ~40-50c range, and I could see the temps rise and fall. With this E7500 (running at 300fsb / 3.3ghz) it just reports 100c no matter what. The heatsink doesn't feel hot, and the chipset temp is low just like it was with the E5200.

Is this some kind of glitch? I doubt an actual 100C+ C2D would be stable enough to complete benches. Windows Experience Index, Sandra, 3dmark Vantage, etc complete without issue with predictable scores for the hardware at hand.

The mobo is an Asus P5KPL-CM mATX G31 mobo.

Any thoughts? Should I ignore it?

Weird. I cleared the CMOS and took the battery out for a few minutes, put it back in, put in all the settings, and everything is golden. 31C in Windows now, didn't expect it to run so cool, I guess the IHS is really cherry on this one!
