Excess heat can reduce the lifespan of electronics. As with any electronic device where you see extensive ventilation holes across the top, it helps to keep them somewhere they get good airflow, as compared to, say, cramming them into a narrow shelf, or closing them behind the glass door of an entertainment center. And don't stack things on top of them, which also blocks the ventilation holes.
