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

Bitcoin is backed by the full faith and credit of YouTube comments.

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

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

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

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

exactly that
