I'm running Ubuntu 20.04 on an older Dell laptop, and recently, I noticed that it has been getting very hot. I tried running sudo pwmconfig, the output of which was;
Found the following fan sensors: hwmon5/fan1_input current speed: 0 ... skipping! There are no working fan sensors, all readings are 0. Make sure you have a 3-wire fan connected. You may also need to increase the fan divisors. I am not sure if the fan works, nor how to start it and that is what I need to know.

I do not know how to start the fans - I even doubt that this is possible - but I know how you can query them:
Install the ipmi tools:
sudo apt-get install freeipmi Then query all sensors:
sudo ipmi-sensors | grep FAN which will give me on my system the installed fans with the rpm.
