U r partially right...they r one of the best out there speed to power wise at stock speeds which isnt achievable with other machines right now but to be fair others r close. I personally dont like them and have made that known but halong has a miner that can be underclocked even if it is cheating with asicboost and not pure hashrate like the s9 is. If bitmain has the s11 in hand and r plannin on sellin them soon that would blow every other miner away for probably years to come again. So far 2 other makers that i know of tried 10nm chips and both were unable to beat the 2 year old antminer s9. No one can deny that holdin that title for 2 years deserves a pat on the back.

With a new antminer i hope they return to a previous design with a solid heatsink with actual thermal paste not thermal adhesive like they have been using since the s5+ miners. I know it will take up some more space but the ability to use high quality thermal paste and have quieter fans with more even heat distribution (since the heatsink will be 1 solid piece all the gaps between the current design would help evenly spread the heat over all the chips instead of just that 1 chip) would deff make up for that added space in my opinion. I know others in data centers r more worried about density and the more they can pack in the more they make everyday but in my care im strugglin with findin enough power to run all my machines...i have the space...tons of space but not enough breakers in both locations to handle the load of more machines so i have to figure that out or stick with the 2 locations i have now :/.
