On my Raspberry Pi 5, the fan on my Armor Lite V5 active cooler does not spin. I've tried to power the fan with an external supply and it runs, so that is not the problem.
I'm lost as to how the PWM dedicated connector on the Raspberry Pi 5 is handled. Is it related to the OS? Or are there settings that are kept at the board level, in some kind of BIOS?
I've noticed that, when executing (found here: https://forums.raspberrypi.com/viewtopi ... 8#p2200693), I get:
The settings for the trip points do not seem logical to me... the first trip point being at 110°C could explain a lot. But I don't know how to change these settings.
Any help would be appreciated.![:)]( "Smile")
