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:

ASUS VivoBook	ASUS ZenBook	ASUS ROG	Others
N580VD	UX310UA	G751JY	B9440UA
S530UA	UX330UAK	G752VL	FX505GM
X507UF	UX360UAK	GL502VMK	FX505GT
X510UA	UX410UA	GL502VSK	FX553VD
X512FA	UX410UQ	GL553VD	TP550LAB
X542UF	UX430UA	GL553VE	X540LA
	UX430UN	GL702VSK	X555LB

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:

Speed level	Temperature (C°)
0 (off)	54 and less
1	55 to 59
2	60 to 61
3	62 to 64
4	65 to 67
5	68 to 71
6	72 to 75
7	76 to 79
8 (max)	80 and more

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
