|I'm finally convinced that it's not software. I did find a BIOS page with temperature readings.|
So here's where I'm at now:
System 1: Ubuntu (in a rack, and working fine) CPU 37, Board 36, Remote 27.
System 2: Win2k (on my desk, working for the moment) CPU 55, Board 33, Remote 25.
That's right - I'm getting an insanely high CPU reading on the bad system, even though the other temps are stable.
The BIOS also reads that the CPU fan's running at 7300rpm, and I can guarantee from observation that it is indeed running.
So why is my CPU temp so high? Any guesses?
