I am trying to just run the hashing boards without any fans, which I have found to be all but impossible with BITMAIN's firmware because it shuts down as soon as it detects there are no fans running. So I need something that will run just S9 boards without any fans connected.
Bitmain firmware is dependant on the fans present.
If you have noise complaint, try replacing fans or running them at 0%? The stock fans are 6000 rpm, anything above 3200 is too loud for housing.
