Adjust ATI Fan Speed in Ubuntu

I found this post hovering in my Drafts folder today, the blog post is old but the information still applies.

Currently ATI drivers do not have the ability to modify fan speeds from their GUI. Here is a quick and easy way to manually adjust  fan speeds via Terminal. The commands below work with my ATI Radeon 4870 card, I would assume they will also work with any ATI card with a fan though. Note: ATI drivers from ATI website are required.

To check the temperature of your card:
aticonfig --adapter=0 --od-gettemperature

To change the fan speed:
aticonfig --pplib-cmd "set fanspeed 0 XX"
(Where the XX is replace it with the fan speed percentage)

  1. Thx, my 4850 doesn’t sound like a airplane taking off XD.

    For people that get the message to aticonfig –initial an that don’t work try:

    sudo aticonfig –initial -f

    :D
