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
BTC3.
My thing is I think Bitmain is joining the big boys and then intend to look toward crushing the home industry. It's going to be farm after farm after farm, with the only way a little person really making an ROI is if they go with the cloud mining which Is where they dictate the pennies they give you for up front capital. And your return will probably depreciate faster than a normal investment vehicle. One thing I give scrypt miners credit for. Those guys are fighting back intentionally screwing with stuff to make ASIC hard to bring into their market space and make a decent product. Or a product that could be screwed with and turned into a paperweight with a slight changing of the scrypt. Even Bitmain had to kill their Scrypt miner project. I have no doubt they will try again, but I also have no doubt the scrypt people will fight back again.
