Mind sharing where you got those numbers from? I am almost certain that no Antminer 17 series miner could run for over an hour at anything near 110-120c, let alone 135c.
Honestly, I don't have a source it only came to my mind because maybe they are similar to S9 Chips that have 135 max temps.
However, I recently realized after checking the Skot project called Bitaxe that the max temp shouldn't be more than 90c my reference is the temp he share on his Twitter, The PCB temp and the Braiins auto mode dangerous temp.
I couldn't find any data so this is just my own guess collected from other user's posts.
