Still have the problem with the OUT FAN at 0 RPM

Then there is also the issue with the one hashboard who is dark (leds are off).
And it's hashboard 2 - Unit2

But the best part is, that Unit2 is the only hashboard that "tries" to do some mining...
I know that it's that board, cuz it goes offline (status NA) when i disconnect it from the miner.

Here a pic for you...
