How to Clean a CPU

The computer central processing unit (CPU) unit is often the most neglected part when it comes to regular computer cleaning. The CPU houses the crucial components of a computer and when owners neglect to clean it, dust collects in the vents and the heat generated by the computer has nowhere to escape. Overheating is the number one cause of computer failure. Protect your investment with regular cleaning of your CPU.

Things You'll Need

• Screwdriver
• Canned air
• Cotton swabs
• Rubbing alcohol
• Static-free cloths

Instructions

1. Locate which side the computer motherboard is on and remove the other side panel opposite the CPU unit using a screwdriver. Be careful not to touch any part of the card or any of the cords.

2. Use the canned air to blow air through the computer CPU fan and any other air vents in the casing.

3. Blow air around the internal components, starting at the top and blowing the air and debris towards the bottom. Finish blowing out all of the debris from the bottom of the unit.

4. Wipe the inside panel with a static-free cloth until it's free of all debris.

5. Dip a cotton swab into rubbing alcohol and wipe around all of the edges and openings on the outside casing of the CPU. Use a second cotton swab to dry each area that you clean.

6. Repeat the cleaning process every six to eight months on your computer's CPU. For CPU units that sit on the floor, in homes with have pets or around smoke, clean every three months.
