Interact with Nvidia GPUs via the windows command line.
The state of command line utilities for controlling an Nvidia graphics card on Windows is a little sad. nvidia-smi will give you your monitoring stats (although I have found these disagree with both MSI afterburner and this utility for some stats) but the command is unable to actually set the fan speed in response to the information it is gathering. While those using linux are able to utilize nvidia-settings to acheive custom programatic fan curves, those on Windows are left to battle with a C library: nvapi which is very difficult to follow with a lot of undocumented functions and also has compatibility issues with RTX cards.
nv-settings-cli makes use of NvAPIWrapper to access headscratchingly hard to find in documentaton functions to do things that MSIAfterburner makes look easy.
nv-settings-cli is a standard C# Console project and was built in Visual Studio. Simply clone the repo, open it with Visual Studio and fetch the NuGet packages.
Since this utility sets the GPU fan to a single speed. Its recommended that you install MSI Afterburner so that you can set the fan speed back to Automatic or Curve based once you are finished with testing.
Current functionality can be listed with the --help flag:
Usage: nv-settings-cli [OPTIONS]
Interact with Nvidia GPUs via the windows command line.
If there are no options the GPU fan speed will be set to 50%
Options:
-r, --repl enter a read-evaluate-print-loop which will keep
prompting
for new speeds.
-d, --debug show debug logging
-s, --speed=VALUE set the fan to this speed.
this must be an integer between 1 and 100.
-t, --temp get the current GPU temperature.
-h, --help show this message and exit.
