Fan control scripts for RockPro64

I've got a RockPro64 in a NAS enclosure with a bunch of 2.5" hard drives and the standard issue PWM controlled fan. I was frustrated with the complexity of all the other solutions, when all I wanted was something that would turn the default fan speed down from 255 to 20 on boot. So I wrote it.

A future improvement might be to add some kind of thresholding for increasing the speed and make the service persistent. But hopefully it won't be required for my home setup.

NB the fan speed is always set to 20. If you have CPU/disk intensive tasks, you should probably increase it!

How to use this:

I'm running Armbian 21.02.2 Focal with Linux 5.10.16-rockchip64 on my box, it's probably fine for all recent Ubuntus, with other distros your mileage may vary.

1. git clone https://github.com/pingud98/rockpro64fanctrl.git
2. modify the files as follows: move the fancontrol.sh script to where you would like it to live (I keep mine in /home/jimmy.. probably not the best location, but it works) chmod +x fancontrol.sh edit the fanctrl.service file to modify the path statement to wherever you put the fancontrol.sh script (i.e. /home/$USER) (sudo) move the fanctrl.service file to the /etc/systemd/system/ directory
3. sudo systemctl daemon-reload
4. sudo systemctl enable fanctrl.service
5. sudo systemctl start fanctrl.service At this point the fan (if it's been running at full speed) should slow down to a barely audible level.
