Hi n, and welcome to Apple Discussions.
I've been experiencing thermal shutdowns over the last few weeks and I suspect I may have temperature sensor(s) that have failed.
Find the original install disc with the Apple Hardware Test on it. Boot from this disc while holding down the d key and run AHT to see if it will identify the fault.
Is this CPU designed to step down voltage to run cooler(/slower) if it gets too hot?
I have never heard that, but cannot say for sure.

Thanks for the response. My issue is resolved, so I'll post up in case anyone finds this thread in the future and is looking for answers. Unfortunately my resolution won't be very satisfying, since I pulled a co-worker's first generation Core 2 Duo (A1211) MBP out of a closet and swapped my disk into it. The CPU Core temps on this new laptop fluctuate quite a bit, which supports the suspicion that the sensors in my old laptop were dead.
