Is that supposed to be a real example? It’s just that fans are controlled by the BIOS, not the OS, so fixing a fan problem would usually involve either updating your firmware, which I have never seen done via a terminal command, or changing a BIOS setting, which could involve rebooting and holding a key like F2 to enter the BIOS settings menu (not Linux, usually a quasi-graphical mouse-driven UI) to change something there.
