Might be a good idea. For my part I have no idea why that happens. I don't find
anything in the chip datasheet, nor in the code, nor in your configuration,
that would explain this behavior :-(.

One interesting experiment might be to check what happens if you set
pwm2_auto_point1_pwm to a value between 1 and 4. If that results in the fan
running at full speed, we have some indication that either the fan or the
board hardware is causing this behavior.

Thanks,
