asus-fan-control (AFC)

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

AFC solves the problems above and even more. Tested devices with links to their first testers:

ProTip! Your device is not in the table? Take a look at contributing.md file and you can easily add it.

Compatibility notes:

• Devices with AMD processors do not work with AFC.
• Devices with the 7th gen Intel processors work well.
• Other devices may vary.

Install

Dependencies

• systemd suite
• acpi_call module (see below)

Using GitPack

AFC supports GitPack. Global installation/update:

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

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

From AUR

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

For AUR installations, enable running AFC automatically:

sudo systemctl enable afc

Usage

AFC 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.

Custom Temperatures

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

GUI

Did you know that AFC has a graphical user interface extension? Visit afc-gui for more details.
