Default Re: Fan speed of GTX 580 stuck at about 30 %

I have an old 6600GT which does the graphics (and is used by X). The GTX580 is only used for calculations.

Thank you very much in advance!

Just follow these instructions:

i.e. temporary connect a second monitor (there is also another way) and then just add in the Section "Screen":
Option "ConnectedMonitor" "CRT"
Option "Coolbits" "5"
and you will be able to control the fans. I use that and it works under Suse and GTX580 3GB.
