mm thermaling mm = bad thing or built in and safe

[BrianG]

Thermaling is done via measuring temps and shutting off the output, so it is designed for it, but it's a safety device so shouldn't be run that much constantly. Running things that hot often will shorten the life span. If it happened just once or twice, no biggie. Also, if it was run that hot, was it being otherwise pushed beyond its spec?
