Introduction

The CPU Cooling Fan allows for continuous cooling of the CPU also known as the brain of a computer inside a laptop to not overheat and burn the user.

This CPU Cooling Fan can be prone to issues of overheating due to clogging or a faulty fan. If you believe the fan is not faulty and only needs cleaning, you can remove the fan and cleanse it with a computer duster.

This guide will go step-by-step on how to remove a clogged or faulty cooling fan.

Check out the Troubleshooting guide for other issues that could be related to the fan.

CAUTION: Placing the computer on a cloth surface such as your lap, a bed, or a couch cushion, can restrict or completely block the airflow. Prolonged air restriction causes overheating and potential damage.

CAUTION: DO NOT continue to use the computer when a fan is not working correctly. Overtime, exposure to consistently high temperatures can damage other important internal components.
