Ah, that would explain a few things.  Guess I'll shut it off then
until I get enough time to see what state it's really in.

Turned out not to be too difficult to roll my own.  One of the
attached two files use my "extract" program


and lm_sensors and that's pretty much it to monitor CPU T and Fan
speeds, with a final poweroff if a value gets too badly out of range,
logs and warnings otherwise.

[For Unix purists extract could be eliminated and replaced with
sed, set, awk or the like, but it's my Swiss army
knife program and builds and runs on every OS I've tried so
far, so I tend to use it a lot.]

sensor_monitor is the /etc/rc.d/init.d script and should work as
is on Mandrake, RedHat, and other similar systems. 

sensor_monitor.sh is the daemon script, mine lives in /usr/local/sbin

When running it doesn't go above .3% CPU, and then only once every
5 seconds, so the load is negligible.
