I am not able to get fan control working. It always says, that there are no PWM Fans even if there are. Anyone expiring something similar or got an idea how to fix it?

Kind regards


  • Have you manually modified the file /etc/default/grub with a noacpi variable?

I think your system can't load fancontrol driver. You can try editing your grub file :

sudo scratch-text-editor /etc/default/grub

and modifying the line ending with "quiet splash" to look like :

GRUB_CMDLINE_LINUX_DEFAULT "quiet splash acpi_enforce_resources=lax"

Save the file and:

sudo update-grub 

After reboot you must install appropriated software like:

sudo apt-get install lm-sensors xsensors fancontrol
