[PROBLEM] R-Pi 4B 4G - PoE - Fan issue

I have no experience with the PoE HAT but this seems a perfect question for the Raspberry Pi Forum (where many similar questions have appeared). 

The only thing moOde-specific about this question is the version of Raspberry Pi OS (aka RaspiOS, previously named Raspian) we use. Here's a relevant quote from the build recipe for moOde 7.0.1

Code:

# - Based on RaspiOS Buster Lite 2020-12-02 (10.6)
# - Bump to Linux kernel 5.4.77 build #1371
