So instead of 1watt per Ghash it draws 10watts per Ghash ? Huh

Maybe the fan draws a few watts?

Fans are in the order of 1-3 watts

Never mind, still quite unexpected though.

50 watts, 80C.
Minteresting. I wonder how many chips are under that heat sink.

1 in words: One
That's 10x the initially advertised power efficiency and 0.83x the initially advertised total hash rate.

exactly that

Perfect. Noisy, running hot, and a larger power draw than posted. Could make a nice heater.

Yeah, 80C with the fan at "hair-dryer" levels worries me. If this 5 GH/sec box is hair dryer loud, I am not going to be very thrilled with the noise of the 60 GH/sec and 30 GH/sec boxes I ordered for my one bedroom condo. Sad

I really think they have a big cash flow problem!
Instead of sending to their first customers,
they send the devices to media -->  more preorders.

I would not be surprised if the system collapses soon
