Many electronics can require a considerable amount of wattage to stay powered on and performing at their best, such as HDTVs and powerful home theater receivers and amplifiers.
Without proper ventilation, these components can produce high temperatures that can cause harm to electronics and damage the cabinet that houses them.
Most electronics rely on the natural motion of air in the room around them to dissipate the build-up of heat. But for systems enclosed in a non-ventilated media cabinet or stacked on top of each other, the lack of any natural air circulation will generate pockets of hot air around the components. When this occurs, the temperature will keep rising if not ventilated, often resulting in expensive damage over time.
Electronics begin to break down and fry at temperatures above 120 degrees. However, the hotter the temperature, the less functional the machine will become. Most systems tend to run 10 to 20 degrees hotter than room temperature, so anything you can do to reduce the build-up of heat will help to better protect your investment.
The following techniques will help reduce heat, increase ventilation and ensure that your components remain cool and run smoothly.
