At least one referenced file is missing or doesn't have
correct privileges. Either some required kernel
modules haven't been loaded, or your configuration file is outdated.
In the latter case, you should run pwmconfig again.

As of now my fans are stuck on maximum speed. They're plugged into a corsair commander pro.

Re: [SOLVED] pwm fancontrol setup help

Run

 sudo fancontrol 

/forehead

It stops controlling the fans when I close terminal ?? how would I make it persist through reboots and run without terminal open ?

https://wiki.archlinux.org/title/Fan_sp … Fancontrol -- note the sentence about enabling a systemd service, and generally get used to check the wiki for "obvious" issues and solutions.
