One system I have (an AMD K6/233 with a VIA motherboard) has an
audible overtemperature alarm on it which somehow works even while
NetBSD is running.

I noticed this last summer when running the distributed.net rc5/des
cracker on a very hot day.  The system was *very* hot; one
contributing factor was a non-working power supply fan (bad bearings).
