Axiom Home Page Forums General Discussion Home Theater Does my receiver have enough ventilation?

I hate to say it, but the best rule of thumb I have found is that you want at least half as much space above the equipment as the front-to-back measurement of the ventilation grill (ie almost a foot for most receivers). Anything less and you do start to restrict the convection.

I imagine anything runs cooler than my HK but just guessing -- it idles hot but at least it doesn't get much hotter when it's working hard.
