Changing fan speed of ATI under linux


Having multiple GPUs under Linux means you are especially interested in wanting to adjust fan speeds manually. The trick is to change the DISPLAY to the device you want to alter.


Example for two devices:

$ export DISPLAY=:0
$ aticonfig --pplib-cmd "set fanspeed 0 60"

$ export DISPLAY=:0.1
$ aticonfig --pplib-cmd "set fanspeed 0 60"
