If your system is Intel / NVIDIA mixed setup and is having random issues when not reaching 95*C or above, then most likely it is an issue with your Heatsink/Fan/Thermal Compound. auth /var/run/sddm/ nvidia-settings -a /GPUFanControlState=1 -a /GPUTargetFanSpeed=95Ĭhange the values to what you need.U can't control the CPU/GPU Fan simple as that, it has a hardcoded firmware based preset within the BIOS that controls the fan speed curve, based on temps. Here's the simpler version: ps -ax | grep Xorgįind the path to the Authorization File string that looks like I didn't need that since I can just plug a monitor (powered off) into the HDMI outlet. (Note: you may need to plug in the monitor first and turn it on, otherwise, there's a super interesting workaround option to run a new X server (e.g., X :0 & export DISPLAY=:0 avialable on the nvidia forums). Get the Xauthority for the current Xserver. (Note: I have SDDM (Simple Desktop Display Manager) rather than GDM (Gnome Desktop Manager) installed). Here's the bash commands that enabled me to change my fan speed from the cli, when ssh tunneled into my desktop. None of the above answers worked for me using the nvidia-settings GUI. 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.
In my limited experience, setting it too high had no effect. If you set this too low, you will get an error. Where the 0 is my GPU number, and the 90 is the maximum power in watts. =END OF ANSWER=Īnd 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 nvidia-settings -a "/GPUFanControlState=1" -a "/GPUTargetFanSpeed=55"įor a much more detailed overview of this feature including multiple GPU fans, check out this thorough documentation Nvidia Overclocking and Coolingįor a somewhat rambling and wayward thread which lead me to the above link, check out Set Fanspeed in Linux from Terminal Importantly I note that my 1070 Ti is GPU 0.
Gives information about the GPU(s) and their numbers. To tell nvidia-xconfig to allow the fan to be controlled in the command line. To control Nvidia GPU fan speed via Terminal on Linux Mint 20 with a 1070 Ti: sudo nvidia-xconfig -cool-bits=4
