Installed the 313.30 (or similar drivers)? No nf file? No Problem. You also have to set PowerMizer to 'Prefer Maximum Performance'. You must go into the NVidia X Server after every restart and set the Thermal Settings. I suggest you keep the temps below 70☌ if possible. You can also see the GPU temperature from there. Once you do this you can directly control the fan speed by sliding the slide bar. On the left hand side, under your GPU, ' GPU 0 - (GeForce GTX 570)' for example, you should see a Thermal Settings entry.Ĭlick on it, scroll down, and accept the agreement.

Restart the system and open NVIDIA X Server. Note that you will need a cable plugged into each GPU for this to work (or tell the system to think that the cards are plugged in). If there is more than one device, 'Device1', 'Device2', then you will need to add Option 'Coolbits' '4' to each section. The following also works for Ubuntu 12.04 and 13.04Īfter installing the NVidia drivers, you can facilitate fan controlled cooling by adding Coolbits.Ĭoolbits is basically an optional NVIDIA X Server component that adds a slide bar to control GPU fan speed.Įdit /etc/X11/nf, by pressing Alt+F2 and typing gksu gedit /etc/X11/nfĪdd Option 'Coolbits' '4' under the Device section, and save the file.
