Fan control for ASUS devices running Linux.

In default, some ASUS devices running Linux control their system fans inappropriately. Typical symptoms include:

• Running fans even when not under any load
• Not running fans under load appropriately
• Spinning up fans in short performance peaks

Asus-fan-control solves the problems above and even more. Tested devices with links to their first testers:

• Install
  • Dependencies
  • Using GitPack
  • From AUR
• Usage
  • Custom Temperatures
  • GUI
• Useful Resources

• systemd suite
• acpi_call module (see below)
• dmidecode tool (see below)

Asus-fan-control supports GitPack. Global installation/update:

sudo gitpack install github.com/dominiksalvet/asus-fan-control

If your system has APT, GitPack will install acpi_call and dmidecode automatically.

We have an AUR package available. Global installation/update:

mkdir -p /tmp/asus-fan-control/ && cd /tmp/asus-fan-control/ &&
git clone https://aur.archlinux.org/asus-fan-control.git . &&
sudo makepkg -si

It may be a good idea to also enable running asus-fan-control automatically:

sudo systemctl enable afc

Asus-fan-control does not run in the background (i.e., it is not a daemon process). It is executed automatically whenever necessary (e.g., on OS boots) to keep the effect of a permanent change. It is also possible to invoke it manually as shown below:

sudo asus-fan-control

It uses custom temperatures if previously set, otherwise the default temperatures are used.

The fan speed policy is usually defined by 8 increasing numbers representing temperature boundaries in degrees Celsius between individual fan speed levels. E.g., UX430UA's default temperatures are 55 60 62 65 68 72 76 80 as shown:

To use your custom temperatures, use the set-temps command. For example:

sudo asus-fan-control set-temps 45 50 55 60 65 70 75 80
