I installed Fedora 29 to Asus X542U. Now fan is working always and I can not control it. I tried sudo modprobe asus_laptop command but result is:

modprobe: ERROR: could not insert 'asus_laptop': No such device

also I typed

dmesg | grep asus

result is

[    5.353567] asus_wmi: ASUS WMI generic driver loaded
[    5.358125] asus_wmi: Initialization: 0x1
[    5.358180] asus_wmi: BIOS WMI version: 9.0

[    5.359947] asus_wmi: Number of fans: 0
[ 9813.808938] asus_wmi: Unknown key cf pressed

You can see asus_wmi: Number of fans: 0.

also I checked fancontrol service

➜  ~ fancontrol
Loading configuration from /etc/fancontrol ...
Error: Can't read configuration file

➜  ~ systemctl status fancontrol         
● fancontrol.service - Start fan control, if configured
   Loaded: loaded (/usr/lib/systemd/system/fancontrol.service; disabled; vendor>
   Active: inactive (dead)

I started fancontrol service with this command: systemctl start fancontrol

but again it is not working

➜  ~ systemctl status fancontrol
● fancontrol.service - Start fan control, if configured
   Loaded: loaded (/usr/lib/systemd/system/fancontrol.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

there is no fan info in output of sensors command

➜  ~ sensors

Core 3:        +45.0°C  (high = +100.0°C, crit = +100.0°C)

What should I do ?

Have you checked the system BIOS for settings relating to fan control? I had a similar issue on an HP laptop and managed to sort it out from there.

  • i checked BIOS but i can not find any settings related to fan control. itshows only fan rpm info. i think problem is fancontrol service of linux – user4757345 Dec 14 '18 at 14:56
