This is what's happening:

I decide to set up my laptop sensors for watching my processor temperature, and I then use pwmconfig to get my fan cooling my processor right. It all works out, but here's the catch: When I close my laptop lid and in turn suspend it, the temperature of my cpu is locked at 26 degrees celsius, and my fan's RPM is stuck at 0, and will randomly flicker to the speed it should go for 26 C. I have no choice but to stop the fancontrol daemon and let my fan be full speed all the time. This doesn't affect my battery much, but I'm more worried about the lifetime of the fan. Any help would be much appreciated.

Info:

I'm running Linux Mint Sarah with the 4.4.0-28-generic kernel.

the sensor I'm using is called dell_ssm-virtual-0 using the CPU temperature, and none of the ambient.

I am using a Dell Inspiron 11 3147.

  • If it can reassure you, fans usually operate better and longer when running at full speed. – Julie Pelletier Jul 11 '16 at 22:41
  • @JuliePelletier I'm mainly worried about accumulating dust. – SpecialBomb Jul 11 '16 at 22:43

I know this an old question but I had a similar issue and turned to be a bug in the system (Linux Mint) related to nvidia drivers. After updating the problem was gone.

  • After updating ... the whole system? The kernel? the drivers? – Jeff Schaller Oct 16 '18 at 11:11
  • After updating nvidia drivers + some mint core packages, but I suspect that the bug was in the nvidia package – Carles Oct 16 '18 at 11:14
