If you have the proprietary drivers installed, there should be a nvidia-settings utility which will enable you to make all sorts of changes to the configuration (but see below). I use this in conjunction with the nvdock taskbar application.

To adjust the GPU fan control, you will also need to add following to the /etc/X11/xorg.conf file, under "Device":
Option "Coolbits" "4" 

I hope this helps!

Hey @Robvv thank you for your reponse! I have coolbits enabled and I can manually adjust the fan settings, I also managed to find a script that manages coolbits configuration depending on the temperature of the GPU, however it would be nice if we found someone who could make a GUI for such a script so we would be more open to newcomers that would like to do the same, I personally like to keep my temps of gpu bellow 60 degrees because it extends the life expectancy of the gpu a lot and a fan can be replaced.

I am wondering does anyone know how to make practical simple GUIs for bash scripts?
