I guess it’s not the only fan inside the computer? For further investigation one needs a photo of the system, with the settings of other fans.

Just a quick guess: it could pull heated air from your cpu eg., or work against the airflow of other fans in your rig.

Nix might be a bit overwhelming when his first installation of linux was only a few months ago, I guess :D

isn’t it the other way? Ubuntu/Kubuntu -> Mint -> Arch-based (Manjaro, …), Arch … -> “btw”
