How to Clean a PC Using Compressed Air

Like everything else in your home, your computer collects dust and debris. As this builds up, your computer's cooling system becomes less efficient, leading to a hotter system. To make matters worse, dust can clog up your computer's fans and prevent them from spinning freely at full speed. Technology website CNET suggests cleaning your computer with compressed air every six to 12 months.
