I've got an old GTX 1080 which I've had to do a fan replacement on. But now when my PC is idle and every other fan in the computer are off, the fans on the GPU will keep spinning up and down every 2 seconds or so, and these aftermarket fans are very rattly when they spin up and cause a very loud burping sound. I'd rather they were always spinning slow on idle as that would be silent in comparison... How can I control the fans of the GPU?

Love this fan control program. Super lightweight and allows a lot of customization for fan curves.

In the terminal run:
sudo nvidia-xconfig
sudo nvidia-xconfig --cool-bits=4
restart your computer and search for NVIDIA X Server Settings in the Dash. There should be an option to change fan speed under Thermal Settings.
To control Nvidia GPU fan speed via Terminal on Linux Mint 20 with a 1070 Ti:
sudo nvidia-xconfig --cool-bits=4
to tell nvidia-xconfig to allow the fan to be controlled in the command line. You may need to reboot here.
nvidia-smi
Gives information about the GPU(s) and their numbers. Importantly I note that my 1070 Ti is GPU 0.
nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUTargetFanSpeed=55"
For a much more detailed overview of this feature including multiple GPU fans, check out this thorough documentation Nvidia Overclocking and Cooling

And as an extra tidbit not asked for in this question, you can also adjust the power output of your Nvidia GPU with:
sudo nvidia-smi -i 0 -pl 90
Where the 0 is my GPU number, and the 90 is the maximum power in watts. If you set this too low, you will get an error. In my limited experience, setting it too high had no effect. I found I can get 95%+ performance for ~75% energy cost by setting the power level to 100 in the above command in my mining rig, but I imagine other power conscious users would appreciate this too.
