I haven't been paying attention. Did this resolve?

The reason I was concerned with temperature is that most folks don't pay 
attention
to how most instrumentation handles heat normally. If you start OUT at 
90C, then
you simply have no reserve for normal device heating. You have to pay 
close attention
to what your resistors are doing, your output drivers.

Example: you design a normal 25C product. Inside the case, due to normal 
heating of the device,
poor circulation, etc you get to 35C very easily. If you start out at 
90C, where can the heat go?

That's why I was concerned with temperature. I have designed sewer pipe 
robots that have to
operate at 40C, and there was a decreased lifetime (enclosed DC 
gearmotor in a sealed case)
due to trapped heat.
