Update: Since Karmic came out I no longer need to run this….

Update: I have gone back to using this script because my laptop was getting too hot. I also tweaked it a bit for my new macbook pro 7,1.

Here’s a daemon written in python to monitor the temperature and control the fan speed in linux. It depends on the applesmc module available from: https://wiki.ubuntu.com/MactelSupportTeam/PPA.

Main Script:
copy to /usr/local/sbin/mb-fancontrol (note that the .py is removed!)

Init Script:
copy to /etc/init.d/mb-fancontrol  (note the .sh is removed!) and
run ‘update-rc.d mb-fancontrol defaults’
