Linux is great and easy to use, said nobody ever
advice
@mavica_again Its the /usr/sbin calling.
If you are not familiar with that directory you can read about the basic hierarchy at `man hier`.
*nix system really unfold their simplicity from the top down perspective. trying to figure stuff out from the user perspective is cumbersome and often futile.
Thats why i recommend using bare distros like void, bsd derivates or similar to learn about the big picture. more "prefabricated" distros tend to startle you at every turn with complexity.
re: advice
@mavica_again to be more concise:
type literally `man hier`. Read that.
Use applications with the correct permissions.
Use root/sudo to manipulate hardware directly. As is the case with fancontrol.
