Fan Control for Nvidia GPUs for Linux. It gives control back to the driver after work is finished, can be used as standalone Python script. It was a passion project of mine, being a learning experience into how drivers and fan curves work.
Controlling nvidia gpu fan requires an X server to be running and be on Linux.
Follow these commands to set up the X server.
$ nvidia-xconfig --enable-all-gpus --cool-bits=7 --connected-monitor=Monitor0 --allow-empty-initial-configuration --force-generate
$ xinit &
$ pip install gpufan
You can use command line script:
$ gpufan constant -g 0 -s 60
Or in a python script:
import gpufan
first_gpu = 0
gpufan.constant(first_gpu, 60)The above script, puts GPU 0 in constant mode with 60% speed. You can use aggressive or driver modes too.
In aggressive mode, a small increase in temperature causes a large increase in fan speed.
gpufan.aggressive(second_gpu)
The bottom commands give control back to the driver manually. Please note that after execution is finished, this line is automatically called so you don't have to.
gpufan.driver(first_gpu)
gpufan.driver(second_gpu)
