Hello. I need to manage fan speed due to temperature.
I have Raspberry Pi 5. I updated all RPI OS and EEPROM to the last version. I connected Waveshare POE M.2 HAT+. When I power ON RPI the cooler works all time on maximum power speed.
I made changes to the /boot/firmware/config.txt: and rebooted device. No changes happened.I decided to check some information:How to enable cooling_fan management?
