This is for the latest 6.1.y XU4 kernel as of October 2023

What does it do?

Makes Odroid XU4 fan silent on idle load and quite on medium load

Is it safe to use?

When script quits it brings fan mode back to automatic "factory" settings.

Usage

sudo apt-get install git
git clone https://github.com/f1vefour/odroid-xu4-fan-control.git
cd odroid-xu4-fan-control
chmod +x odroid-xu4-fan-control.sh
sudo ./odroid-xu4-fan-control.sh

Installation

To make it start when system boots:

edit odroid-fan-controller and add the path of the odroid-xu4-fan-control.sh script (full-pathname), then do the following to add it to the runlevels

cd /etc/init.d/
#adjust to correct, absolute path below
sudo ln -s ~/odroid-xu4-fan-control /etc/init.d/odroid-fan-controller
sudo update-rc.d odroid-fan-controller defaults

you can also use the following to start the controller

sudo /etc/init.d/odroid-fan-controller start

or

sudo /etc/init.d/odroid-fan-controller stop

to stop the controller
