If this helps, it's in my personal archive here:

I'll attach my own versions of Paul's scripts I nabbed at the time -
from memory all I did was add some chkconfig lines for Red Hat/Fedora
to the init - will be ignored by other distros - and a signal trap
in the main script for ^C and exit to always turn the fan back on in
case I was testing.  I maybe also changed the path to /usr/local/sbin.
The credit for the idea and script should go entirely to Paul.

To install just:
# cp ibm_manage_fan.sh /usr/local/sbin/
# cp init-script /etc/init.d/ibm_manage_fan

and turn on the service for your distro in the usual way - for
Fedora/RH:
# chkconfig ibm_manage_fan on
# service ibm_manage_fan start

You can tweak the battery and AC temperature limits.  Be *very*
careful using the scripts obviously.  I haven't checked for other
possible cases where they may crash and the fan stay off - in which
case you'll melt.  I don't really use it much.
