I have a 37U rack in a ventilated closet. The P5 is at the center of the rack, with 3-1/2" separating it and a class A/B mono amp (below the P5), and another 3-1/2" separating the first mono amp and a second A/B mono amp.
When listening to 2-channel music, I put my amps in Class A, and they get hot, as Class A amps do.
At what maximum temperature is the P5 designed to safely continuously operate?
I’m not too concerned about temperatures in the rack during a 2 hour movie, or 2 hour music listening session, but more concerned with the continual temperature of the P5, as my preference is to keep my amps on 24/7, in idle. But even at idle, in A/B mode, the amps produce enough heat to cause my fans to power on, and I want to make sure I’m not exposing the P5 to excessive temperatures.
