I have a Teensy 4.1 that is placed in a metallic enclosure outdoors.

As expected, during daytime, the Teensy's 4.1 temperature (as measured by the temperature library) is quite high but I did not expect it to be 167 degrees on a hot day. The rest of my circuit's components can withstand up to 175 degrees (ambient).

The Teensy 4.1 has been working fine and no instability was present.

I realize that I can reduce its clock speed (< 600) but I need maximum performance for my application. I also have built into my code to de-throttle the processor but I set the temperature at over 175 degrees.

Would this operational scenario eventually destroy the Teensy?

Thanks in advance for the community's input.
