Do you support the R4?

Interesting, stats for human beings?
You have a little typo:

Any plans to fix this?

It is the same as running an older batch S9 with two boards (8THs), except silent. And they pull 2/3s the power of the older S9s as well.

Its design is probably unnecessary in a warehouse, but perfect for the living room.
The T9 is close, but it still uses dual fans. I wonder if the Avalons are quiet enough, but somehow doubt it. Someone told me 65db, which is 10db above the R4.

The fan on the R4 should be run at 100% by disconnecting the control wire, they are very quiet even at the max 3200rpm (i saw another (slower?) batch running max at 3000rpm).

Compare it with the useless A3 and tell me they were worth more spending resources than this. An Scrypt model using this same design would have probably been great as well.

I guess in the end you have to get a T9/S9 and put it inside a cooler box with holes and thermal insulated ducts...

I have to wonder why none of the competition has cloned this design. There are many places where you want to have these silent miners...

How about Bitfury? I managed to find they sell shipping container sized units, that take about 30mw of power, but can't find what hashrate that would produce. Their page only lists per chip performance.
