Run as a service?

[millercentral]

Thanks for this. If I want to load my custom fan curve at system start and have it maintained while the system is active can I run the fan.sh script as a service? If so, could you provide an example of what that could look like?

Thanks, I think it is possible, you can choose to launch fan.sh or nvidia_fan_control.py when system start, here is an example, I think it should work.(Which means I haven't tested it yet.)

Create and edit a systemd service file:

sudo nano /etc/systemd/system/nvidia_fan.service

[Unit]
Description=NVIDIA Fan Control
After=multi-user.target

[Service]
Type=simple
ExecStart=/path/to/nvidia_fan_control_linux/fan.sh
User=root
Group=root
Restart=always

[Install]
WantedBy=multi-user.target

Enable and start the service:

sudo systemctl enable nvidia_fan.service
sudo systemctl start nvidia_fan.service
sudo systemctl status nvidia_fan.service

This should ensure the script runs with root privileges at start.

I'll give it a try, thanks!

This worked for me on ubuntu 24.04 with my fan flickering evga 3060ti, thank you so much!

if you have SELinux active (e.g., in Fedora) it can block the execution of the shell in the service from your home dir.
You can move it to e.g. /usr/local/bin by running sudo install -m755 ./fan.sh /usr/local/bin then you'll need to modify the service like this: ExecStart=/usr/local/bin/fan.sh.

Alternatively, you can just set ExecStart=/bin/bash -c 'cd /path/to/nvidia_fan_control_linux && source fan/bin/activate && python nvidia_fan_control.py'.
