Or, another sequence that can be tested and might work: Add the setting gpu=true to the Extra Clients Options panel of the Expert tab of FAHControl. (... and you may have to restart the service).

NB: I've used this method on single card installations only so you may need to adjust one of more steps to account for multiple cards.

Open nvidia-settings.
Select "X Server Display Configuration" from the options on the left.
Click on "Save to X Configuration File".
The save screen should show /etc/X11/xorg.conf as the file to merge with.
Click on Save.
Quit nvidia-settings.

Open a terminal and type(replace gedit with you favorite text editor):

Code: Select all

gksudo gedit /etc/X11/xorg.conf

Scroll down to Section "Screen"
Within that Section and before EndSection add the following:

Code: Select all

Option    "Coolbits"  "4"

Save and quit.
You need to pause folding at this point and reboot in order for the setting to take effect. (logoff and logon may also work but I prefer reboot)

After your o/s comes back up you again start nvidia-settings and this time select Thermal Settings.

You should now see a box next to "Enable GPU Fan Setting". Check that box and change the fan speed to your new setting ... press enter and click on Apply. (You can also use the slider in which case pressing enter is not necessary)

You might need to quit and restart nvidia-settings before it will properly show the new speed. Assuming the new speed is higher than it was before performing the above your temperature should be lower.

If you find your new fan setting does not survive a reboot of your system you can do the following:
Create a file in your home directory called gpu_fan.sh and add the following to it:

Code: Select all

#!/bin/bash
nvidia-settings -a [gpu:0]/GPUFanControlState=1
nvidia-settings -a [fan:0]/GPUCurrentFanSpeed=70

The above is for one GPU so you would add two more lines for gpu:1 and fan:1 ... and may need to adjust the Speed from 70 or create two separate files ... one for each GPU and add both to Startup Applications.

Now you need to find Startup Applications and add gpu_fan.sh so that it runs when Linux starts. Use the full path in the command line:
/home/yourusername/gpu_fan.sh

You may also need to make gpu_fan.sh executable although I'm not sure if it's necessary.
Open a terminal and type:
chmod +x gpu_fan.sh

Here's a related link but I have changed quite a few steps:

sudo nvidia-xconfig
sudo nvidia-xconfig --cool-bits=4
sudo reboot
