I've seen people recommend using sensord to shutdown on overheat but
can't see howto, also this wouldn't do anything for the hard drives,
similarly hddtemp seems to just do reporting with no option to shutdown.
collectd has options to monitor both but no tools that I can see to do
anything if an error condition arises.
My reading has led me to believe that the kernel can do at least the CPU
part of this for you, if you've got a better supported sensor chip,
which I don't, but I can't be alone, so what do others do in this situation?

Hi David
A shell script did occur to me, but I thought with so many hardware
monitoring daemons, and so many hardware monitor logging daemons, and so
many GUI widgets for outputting the results of the previous 2 in
practically every desktop environment ever conceived, some of which
allow you to automate tasks on event conditions, there *MUST* be an
option for headless systems other than some loopy shell script. (pun
intended, not offense)
Have you tried to get sensord to control your fans? I tried this first,
have the fans off until the CPU hits 50 or whatever, sadly doesn't work
with my MB (which was very cheap 4~5 years ago) but you may have more luck.

Nice script though, short, obvious, to the point, I may well end up
nicking it and adding an hddtemp call.
Sorry for relaying out your email, some people get really narky about
top posting.
