...now we have to settle for airplane turbines
Improvise...
I'm sure you can think of doing something to contend with the "airplane turbines." Not even the S3's were designed for home mining if a home miner sought to have considerable hashing power for a home. There would not only be sound to contend with but also lots of heat. I know cause I had 18 x S3's along with 6 x S5's, 5 x S4's and 15 x SP20's. I suppose BITMAIN could make a smaller miner with less hash rate. However, I'm quite certain people would complain about the price of the miner and the rise in difficulty to boot.
Bottom line: If someone chooses to mine from their home [With a considerable amount of hashing power], they need to come up with a plan to deal with the heat most of all; as well as a plan to deal with the noise. I came up with a plan to deal with both and implemented it. Yes, it was an initial up front investment but it has paid for itself over time. Even data centers have an initial up front cost to deal with sufficient power, heat distribution and noise distribution if they are concerned with noise. One needs to be concerned with the heat more than the noise in my opinion.
I would also think it is Bitmain's prerogative to make their miners as they seem fit. If people don't like them, they don't have to buy them. Bitmain, designed them for "their" data centers. If someone wants to build a makeshift data center inside their home like I have, they can manage the heat and the noise to acceptable levels. Bitmain, is marketing to those with data centers when they engineered, designed and built the S7. It was not built for those who wish to have a considerable amount of hashing power with several rigs in their homes.
I think its unfair for anyone to criticize the business plan of a business that caters to a particular clientele (data centers) and demean them for not molding their business plan to home miners. I still say the home miner can be profitable [With some up front costs]. Once those adjustments are made to mine from your home, it would pay for itself in due time. Probably about a month or two after ROI on your rigs.
Don't think I'm saying you are criticizing Bitmain. I know you're not. I'm simply encouraging you and others [Who will mine from their home] to come up with a plan to manage the heat and the noise.
Mining closet built downstairs to contend with the heat and noise. French doors are at the entrance to this room the mining closet is built in to contend with the noise. This structure can easily hold 90 - 120 x S7's. However, I would probably have to upgrade my exhaust fan to a TLI 14,700 CFM belt driven fan.
7400 CFM facing the back yard to exhaust the heat inside of a 422 Cubic Feet Structure:
Grilles installed in the doors to allow the exhaust fan to suck cool air into the structure for the rigs to suck cool air into the intake fans and out to the 7400 heat exhaust fan. More grilles will be added in other doors as more rigs are added.
So again, don't think I'm getting onto you for your comments about the "airplane turbines." I'm simply trying to encourage you and others to "Improvise" if you want to manage a considerable amount of hash power out of your home with rigs that are designed for a data center.
Mine was designed and built with the idea of having as many as 90 to 120 rigs inside [Depending on the size of the rigs]. If your idea is something smaller, you could build something smaller on a stand in front of a window with a fan mounted to the window. I'll post a diagram for a design in front of a window on a stand if you like. Just give me the size (measurements) of the window with measurements of how far the bottom and top of the window is from the floor.

. Didn't expect this early shipment. Thanks Bitmain!
