Hello, there. I would like to ask you which rpi pins control the fans. Wiki says that only GPIO 13 (pin33) is used. But in python code there are two pins used. https://github.com/akgnah/rockpi-sata/blob/515f777f773211ae2024bc006c65feea40b20615/usr/bin/rockpi-sata/fan.py#L57-L58
After small investigation with multimeter. I found out that the CPU fan is connected to the GPIO 12 (pin 32) and the top fan is connected to the GPIO 13 (pin 33) . Please update it in wiki.
