We got 6 units in today. All working great, no bad units so far. Hashing around 17-17.2gh/s average. Haven't checking amp draw yet.
Nice are they louder that S7/S9?
Seem to be the same fans, running around 4800 rpm so they aren't real quiet. Our airflow is not ideal right now. I'm sure with proper exhaust/intake the fan speed would come down some.
