I have Acer Swift 3 14 laptop that has Ubuntu 18.04.02 LTS installed. It is dualbooted with Windows 10.Under windows I can clearly hear fans. However when I was compiling Linux Kernel in VM within Ubuntu other day laptop became very hot, I thought it would be normal but out of curiosity afterwards I decided to check my fan speed as I couldn't hear any fan at all since started using the Ubuntu system.I installed TLP btw.So I thought that may be the reason why fan never kicks in(as it was in power save mode on battery). I did lm-sensor detect with default settings as it was the most given respond when I searched for how to check fan speed . I can see CPU temps and they look fine around 40 degrees on idle.That maybe the reason why I never heard of fans as I only did basic text editing and browsing on Ubuntu except VM stuff and maybe tlp was keeping fans from running. That is what I thought.During browsing it was bit worm.I would say slightly warmer than windows but not too much to make me suspicious.However I still coudn't find fan speed even after installing hardinfo.Since I also can't find it on lm-sensor I became suspicious whether it is not recognised and doesn't run at all.Also when I use HW Monitor and other sensor programs under Windows I can't still see my fan speed.Is it normal I can't see any fan info? If not how can I fix it? Thanks for the help.

    Hi it is NC-SF314-52-581R.
  • This is the temperature depending on the speed of the fan, see:

    What is the bios version?

    Thanks for the table.Bios is v1.08.Issue is I can't see fan speed under Ubuntu so I thought it is Linux issue and fan doesn't run at all simply because they are not detected.However I can hear them fine on Windows upon boot and yet Windows programs can't display fan speed as well.So it is unclear whether fans not showing let's say under Ubuntu is matter of not running at all or whether Acer has no sensors for it.

    I already tried those.Unfortunately it doesn't work.lm-sensors hardinfo etc none of them displays any fan data.Same for Windows programs.
  • what version of ubuntu do you install? 18.04?

    what version of ubuntu do you install? 18.04?
    Yes.I would suspect that Linux don't work properly.However then it should display on Windows just fine but it doesn't despite me hearing fan on Windows boot.I don't want to stress CPU under Linux incase it doesn't run at all under Ubuntu. Regardless it is weird why I can't read fan speed under both OS.
  • Does hwmonitor not read fan speed on any of the operating systems?

    Yes it doesn't.
  • OK! Try disabling fast startup in the power options and then reset the battery according to this video:
    Then test the notebook!

    Are you sure that wouldn't have chance to mess anything right? Also can it be that this model has no proper sensors for fans?
  • I've never seen any computer without temperature and fan speed sensors! The above procedure will not damage the notebook. In fact, the ideal is that you disable fast startup, because of dual-boot!

    I checked fast startup and it was already turned off.Should I still reset the battery?Thanks.
  • Yes, you can reset the battery!

    Yes, you can reset the battery!
    Unfortunately didn't work.
  • Have you updated all the notebook drivers on the intel website?
