I installed Ubuntu 19.10 on my new Lenovo 14w laptop and I noticed that the fans are not running at all, causing high temps.

I have installed fancontrol but couldn't figure out the config.

Running pwmconfig results in an error There are no pwm-capable sensor modules installed

And lastly, sensors-detect shows I have AMD Family 15h thermal sensors (driver 'k10temp')

Some posts seem to mention that some Lenovo models have their fans controlled by the UEFI BIOS, however there aren't any such options in my BIOS.

What can I do to get the fan spinning?

Edit: Here's the full sensors-detect output. Couldn't fit in this post due to character limit

Try to Restore BIOS to the default settings.

Press F2 repeatedly when the Lenovo logo appears on the screen, then F9 Restore to the default settings.

Here's the Lenovo 14w user guide if you want to try updating your BIOS to the latest version

try to adjust lm-senors and fancontrol parameters following this guide:

How to control fan speed?

Run :

fwts fan

to check and test fan status, or as How do I know my fan is working in Ubuntu

Finally you can check The thinkfan software is available in the standard ubuntu software repositories, but it does require a few steps to configure.

  • Went through the steps but the thinkfan service can't start due to /proc/acpi/ibm/thermal not existing. I also made sure to upgrade the BIOS before uninstalling Windows. – slightly_toasted Jan 15 '20 at 15:26
  • Check these for more details on thinkfan: http://www.thinkwiki.org/wiki/How_to_control_fan_speed https://askubuntu.com/questions/481459/thinkfan-control-doesnt-use-the-fan-full-potential-when-needed Would you try installing Ubuntu 19.04 or older versions instead of 19.10 as a temp solution to see if this fixes the situation or not, as .04 often are LTS and better-maintained Distribtutions. – Ahmed elesawy Jan 19 '20 at 21:05
  • LTS Ubuntu did not make a difference, manually controlling the fans with echo level x > /proc/acpi/ibm/fan didn't work, and thinkfan service can't be started as it relies on /proc/acpi/ibm/thermal which doesn't exist :/ – slightly_toasted Jan 21 '20 at 13:58
  • Do you have these settings : From the main BIOS menu, choose ‘System Monitor’. Then go to ‘Fan Control’ option and select ‘CPU Fan Speed Control’.

    • Change the control to ‘Manual’ if it is on ‘Automatic’. You can enter the percentage of the CPU fan to work according to your suitability (like 100 will be 100%). ?

  • As I mentioned in my post, nothing fan related exists in BIOS. – slightly_toasted Jan 22 '20 at 21:40
