Hi, just wanted to add my experience to this topic: I experienced a similar problem with the Quad sata hat in connection to running the setup on a Raspberry Pi 4b: the fan of the top board was spinning at full speed, no matter what, immediately from the moment I connected the 12V power supply. After some troubleshooting I was able to isolate the problem. In my case, the fan itself was the faulty part. the oled display worked well at all times, as well as the sata drives with full usb3 speed. after testing the top pcb with another fan, everything worked well. adjusting the /etc/rockpi-sata.conf makes it nice and quiet at lower speed levels. btw, setup for me works smoothly also even with the current raspberry pi os bullseye, both 32 and 64 bit.
so, if you are to run into the same problem with the fan constantly rattling at 100% speed, but display and everything else working fine, you might wanna try to replace the fan. any 40x40x10mm with 5V and pwm (3pin) connector should do. just make sure to have it wired correctly, matching up the gnd, voltage and speed control pins specific to the board.
cheers!
