All my M3's are usually sitting at about 83.5 to 85c. Right above them in the rack I have two S9's that are seeing highs around 59c. Above that are two A741's and they show 33c/75c. The cold side of the room is around 22c. I haven't noticed any problems so far.
Also all my units have a 6" diameter duct going out though the wall into the hot side of my mining room.
My fans are running around 4k.
Thank you, mine are in that range too. I did not realize how hot these ran in comparison to the Antminers. But like Shazam!!! said they are pushing over 2k watts.
The logic of their software is interesting too, it looks like they will hash as fast as 85C will allow and then back off. Avg is almost 12 TH/s though so just as advertised.
