It’s a Desktop computer, mid-tower. I will check the BIOS settings for a setup variable.

Run sensors-detect, if it has pwm controllable fans, you should see something detected in the SuperIO section.

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!

Yea, it needs to have a 4pin connector on the fan to be able to control it.
