PWM Fan Control - Any hacky solutions?

[adminy]

I installed dietpi on the Pi 5 and its been super quiet for the past few days, but I prefer to use nixos, and unfortunately its quite difficult to work without uefi there without implementing a bunch of hacks, but speaking of hacks, maybe if there was some sort of preset simple behaviour that maybe doesn't even take into account temps. Something simple so that I can give the fan a little rest would be nice.

@adminy after looking into how to support PWM-controlled fan specifically under Windows (i.e. a lot - start here: worproject/RPi-Windows-Drivers#23 (comment)).

For non-Linux, I wire the Pi5 Active Cooler +5V to +3.3V on GPIO pin 17 (using solid core jumper wire pushed-into Active Cooler header secured with heat resistant insulation tape) - fan runs continuously but quietly enough for my purposes.
