Not "strangely" but because Win* doesn't put the CPU into HALT mode
when idle, while Linux does. There's a "cpuidle" program for Win* that
cools the CPU down :-)

Perhaps it also depends on how old the CPU is. Apparently AMD uses a
different manufacturing process since summer or fall 1997, and the
newer ones work with 2.9 or even 2.8 V even though they are still
marked 3.2 V (of course, less volts means less heat).

I have a 1998 vintage K6/233 running at 240 MHz with 2.8 V core. Rock
solid by now under Linux. By now I haven't tested that machine with
crashme but it sometimes has considerable load spikes. The mobo has a
temperature sensor under the CPU and it has never reported more than
60 deg C for me; if this is correct, it's fairly good for the small
(but too loud :-() cooler on it and should also be non-dangerous.
