Endish, looking through various homeowners A/V gear on the internet it astonishes me just how often I see receivers and amps with equipment stacked right on top of them enclosed in very tight quarters. I try to keep as much distance between my equipment as feasibly possible because, while far from being an electronics expert, I have always heard and read that heat kills electronics.
I believe a couple or so folks here on the board do run cooling fans (Shag?) and I am planning to install at least one in my equipment rack/cabinet whenever we install the system in our new room in a few days. Better safe than sorry...I believe.
