is it common for bitmain to release china-only products? relatively new to this
any chance this would be available in NA?
Yes, they do that occasionally. They had a GPU miner (G1 I think) that was only ever available in China.
We'll have to wait and see. I'd like to get a couple of those S9 Hydro. If they're as quiet as the C1 was it would be perfect for heating during the winter.
I cannot read Chinese and most of the specs are in picture format so Google translate is of limited use, but I do see 45DBA mentioned. Now weather that is the miner fan, radiator fan, pumps, etc who knows. However is the entire setup only puts out 45DBA this would resurrect home mining where people have affordable electricity.
