Hi Florian,
I have an PI 4 with the POE±HAT. It runs at about 50 °C in Info-Beamer hosted 13 and the fan works.
When testing 14 it runs at about 60°C and I never hear the POE±HATs fan spinning.
Maybe support for the HATs fan is somehow broken with the testing release? Any idea how to debug the issue?
Thank you and best regards,
Oliver
