epz, the Hint 6 is an excellent unit. It has a thermal breaker. If it gets too hot it will shut down. If it is not shutting down you are OK.
clearthinker, I think in general you are right. My old Krell KMA 100s were class A and burned out after 20 some odd years. Components are much better now and more heat tolerant. I expect their life span to be longer.
It seems all the amps I am interested in run hot. In an attempt to improve their life span I use a fan system which you can see on my system page.
My approach to the fan noise was to put the amps in the room under the speakers on a shelf against the ceiling. I did have to put a potentiometer on the fans to slow them down. At full speed I could hear them upstairs.
