My current PC has a fan controller that lets you change fan speeds by turning a number of knobs.
Crazy, right?
If only there was some sort of calculating device that could do it for you as and when you needed to increase and decrease the cooling...
I disconnected my fan controller because who has time to manually change the fan speeds? I moved to FanControl a few years ago because it meant I could get rid of the last vestiges of the Asus fan software that seemed to break every time Microsoft brought out an update, and then I'd have to wait for Asus to bodge together a fix.
