I'm probably a bit late to the game, but I've just set up my first 3b+ with a PoE hat. Everything is working as expected but the fan seems noisy and is on quite often.
I note googling the pi and hat combination that there is talk of speed and temperature control being available in later versions of Rasbrian. Is this something that is available in LibreELEC on the pi?
Any help/advice greatfully recieved...
