Many of these modules require you to add acpi_enforce_resources=lax to the kernel command line to load. This often results in sensors being able to report various temperature and voltage readings, and the fancontrol script ( packaged separately in Debian/Ubuntu ) can be configured to manipulate the fan speed in response to the temperature readings.

You run sensors-detect and it will probe for known controllers and can configure the correct driver to be loaded to manipulate it. Many of these hardware controllers can be detected by the lm-sensors package. Generally the bios ACPI tables don't provide the fan interfaces and just leave it up to a hardware controller to manage. You might look in /sys/class/thermal and see if there are any fans that show up under there and if they can have their settings changed. Unfortunately, I have yet to see a single bios vendor actually comply with the standard. This is the output of the ` sensors` command. I'm still having the same issue.Ĭould it be that my fans are PWM 3-pin where fan speed is controlled by voltage? The way I tried to fixed this is to edit /etc/default/grub to add `acpi_enforce_resources=lax` to the ` GRUB_CMDLINE_LINUX_DEFAULT` and then perform a grub update. usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed Installed modules with ` sudo /etc/init.d/kmod start`. In terminal I typed `sudo sensors-detect` and answer YES to all YES/no questions.

I'm now trying to configure lm-sensors to no avail. I've researched a little and I'm blocked on how to control fan speed and then installed `lm-sensors`and `fan control`. My computer is prone to over-heating when I'm using Ubuntu and so I'm trying to control the fan speeds.
