My biggest concern would really come down to how the Warranty would be affected by running these miners above the stated 30C.
If the numbers at 30C as printed are only for the benefit of showcasing the optimal performance temperature ranges, then I would have no problem with the Miner. My electrical costs could support the increased usage at the higher temperature ranges. I only get maybe 1 day a year above 40C.
I understand though the concerns for others with Margins being slimmer and overall temperatures being warmer longer.
Good job with all the testing, very informative.
*snipped*
resulted in 1545 watts used vs 1366 at 67f
So 87f = 1545 watts
and 67f = 1366 watts
This means I can not put 20 in my solar array which will go well into the 90's in the summer.
But even if you run at 85f you are eating 150 to 180 extra watts.
To be fair the spec page shows 30c as the max it also shows a +- 20 % range which we know know is dependent on heat in your mining room.
