is this what happens when it reaches 80 C or does this mean that it went above 80 C?  The unit still turns on and I can see that I have it set to turn off if it reaches 80 C, but it doesnt look like it did

The unit powers on and I can get to it via the network but it wont hash - I figured it out when I took the sides off and found the burned board.

I dont have any thermal events on my other miners.
