Fan on auto doesn't hit 100% until about 90c,
So I would guess anything under 90c is ok.

Ive never heard of a chip running at 90c being ok. Nvidea 1080 with Asus aftermarket heavy duty heat sinks would have thermal breakdown at 90c. You should contact Bitmain and ask them they usually reply within 3 days,but I would not risk 90c on any device. Weird thing is on D3 i tested the fans kick in 100% when chip reaches 71c,but you say on yours it kicks in at 90C ?
It's common for example for automotive grade chips to support up to 125C. As someone else said, it depends on the chip. Lots of opinions in this thread, but I wonder what are their sources, definitely not a data sheet
This is the only thing I've found in the manual, note that it refers to PCB temp, not the chip:Note: The D3 miner will stop running when the Temp(PCB) exceeds to 85°C, there will be an error message Fatal Error: Temperature is too high! shown in the bottom of kernel log page.
In my case I'll worry if they get close to 90 or if I see more than a few HW errors per hour (the D3 is a useless heater anyway, so why worry?
)Not if DASH goes up to $2000 it won't be useless anymore and with current projections we may be looking at a DASH price of $2k in either June or July and that's being conservative.
