How loud are they ? I doubt they are silent like the S3 but more like an S5.
They got probably the same 70 dB fans on them the S5 does. Front and back. So expect two jet engines.
Sucks, won't be able to run those at home ... never
It's too bad - this chip could be used to make a great home miner. A 60 chip design like the S5 with the improvements they've made in cooling could probably run at about 1600-1700 gh/s somewhere between 0.6v and 0.66v and probably pull less than 400 watts from the wall. Cooling a miner like that would not be loud at all with good fans. That's not too far away from the S3 in terms of heat generated. And they'd probably sell easily for around
