Is there a way to control the CPU fan speed in Ubuntu 20.04? I am using an older Dell Desktop.

It’s a Desktop computer, mid-tower. I will check the BIOS settings for a setup variable. – Bruce1369 Oct 27 '20 at 21:46
Run sensors-detect, if it has pwm controllable fans, you should see something detected in the SuperIO section. – rtaft Oct 27 '20 at 22:00
My system does not have PWM controlled fans, so there is no way to control the fans in my old system. Thanks for the help! – Bruce1369 Oct 29 '20 at 03:09
Yea, it needs to have a 4pin connector on the fan to be able to control it. – rtaft Oct 29 '20 at 13:01
