My batch 3 gets 12.5 Th downclocked to 593 and even then I have to restart cgminer several times for one of the boards to get a decent hashrate. Luckily I can tell within a minute or so if the board is going to get a decent rate but it kind of sucks that it is hit or miss like that. If I don't restart cgminer to get that board working well it hashes about 1.1 Th lower.
The config page still has the shutdown at 80 degree option and the chips are always over 80 so I think we can conclude that the temps reported on previous miners (S7, etc...) were PCB temps. I am getting high 90's (like 98-100) on the chips with the PCB's reporting upper 60's (like 68-69).

watch for heat creep Mine tend to creep to as high as 75-105 unless I clock to 550 vs 650.
much of this issue is summer temps in the solar array shed. we are getting fans set up and will change the venting setup.
this will fix heat issues. and we will boost the clock back up.
At the hottest part of the day they are hitting 100-101. But the PCB temps are right around what the S7's are showing (67-70) so I am guessing the S7 chip temps are hitting those kind of numbers too.
So, What is the difference between temp(PCB) and temp(chip)? I understand the ranges for temp(PCB) is "keep it under 80c and runs most efficient at 58-65c," But what is the safe range and cutoff for temp(chip)?
That would be great - MAybe someone do know when this will happens?
