In an ideal set up, there should be a fan located near the top of the cabinet configured to exhaust out air, and a fan located near the bottom to push in air. Electronics such as receivers and computers within a cabinet will cause air to heat up. Due to natural convection, warmer air which is less dense than colder air will rise on its own. An efficient fan system helps accelerate natural convection by rapidly exhausting warmer air out the top of the cabinet while pushing colder air in at the bottom.
Cabinet fan systems that contain only one fan should have it configured to exhaust hot air out the top of the cabinet. There must be ventilation holes located elsewhere on the cabinet, preferably towards the bottom to act as an air intake. Using fans to push air out will cause negative or lowered pressure…
