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.

sudo apt-get install git
git clone https://github.com/f1vefour/odroid-xu4-fan-control.git
