Quad SATA HAT Assembly and Troubleshooting

Hello All,

I’m having an issue with my Quad SATA Hat running on RaspberryPi 4B 8Gb. The thing is that the fan on the top is active at 100% all the time. I’ve posted in this thread:

I also saw that there are other people with similar problems:

I’ve tried some of the suggestions, but they didn’t work. I’ve ordered a brand new top hat with fan and oled included - same issue.

At this point I’m wondering if I’m doing something wrong, but so far I can’t find anything wrong with the config.

Any ideas are greatly appreciated!
