Hello, I’m new here and got the Quad Sata hat. According to the website, I installed the firmware, but the CPU fan is not spinning. I have now looked a lot in the forum to find something that can help me but unfortunately without success. But what I found out is when I download updates via apt-get update the fan spins all the time with no problem after they are done it stops again. So I think that something is blocking the fan so that it shouldn’t spin.
Have the Rasperry Pi OS 32 bit on it
and the Quad SATA HAT firmware
and also made several times so far to test
