How to Clean a Computer Fan
Heat is your computer's number one enemy, which is why it has one or more fans to help push hot air out of the computer case and pull cool air in. Computer cooling fans are typically installed next to vents on your computer case, but your computer's processor may have its own fans and heatsinks, which sit on top of the processor chip. Dust and dirt then collect around the blades of each computer fan and may eventually cause the CPU fan to break or slow down. If any one of the computer fans breaks or slows down, heat builds up and may damage the processor or other components in the process. To protect your computer, follow these simple steps for keeping your cooling fans clean.
