I've been reading this interesting thread about maximum ambient temperature for operation in a sealed box, but it concentrates on CPU temp.
I am considering a system where the CPU is mildly loaded. This would be a Pi 3 wearing a HAT. I'd like to have your views of the maximum ambient temperature it could reliably operate at considering the system as a whole. That is: including an SD (prolly a Sandisk, largely idle as well) and an active ethernet connection, but excluding power supply.
To put it simply: if a Pi 3 bakes at 60°C (140°F) ambient, does it stop working, or does it "melt down"? What is the sustained ambient temperature level that would probably damage it or shorten its life ?
Thanks in advance for your views.
