I moved my miners into a new room I built. Everything was working fine before I moved the miners. After installing them in the new room, one of my miners firmware crapped out somehow. When it boots up I get a fan error that 1 of the fans is only running at 1200 rpm. Also, BMminer and hardware versions are empty under system overview. If I use the 2nd newest firmware (650M) BMminer and hardware versions show up and I'm able to mine but my fan is still only running at 1200 rpm. Is anyone able to tell me if it's the control board or the fan? My fans are "Fan 3 5280 rpm and Fan 5 1200 rpm". I would assume the fans are in order? Is my Fan 3 the air intake and Fan 5 the out? Should I replace the air out take fan, look more at firmware or the control board? I would be great full for any help. Thanks!

maybe, something is obstructing the fan?

other than that, I had a similar situation (where one fan showed 1200rpm), but it was simply broken and whatever rpm it showed came from its passive rotation due to the first (intake) fan pushing air down the wind tunnel.
