Another thought, it's not over 50c in your mining room, is it?
No, just turned the AC on, the temperature is officially under 22 degrees Celsius.
You can contact Bitmain and get a new control board or get yours looked at for $25 if I remember right.
No way im spending more money on this thing, already bought 2 PSU's for it and had to pay $140 to get it through customs, I'd rather buy another one now...
