Final answer:
Failure to keep computer fans clear of dust and hair can result in permanent damage to the machine through excessive heat buildup. Regularly changing filters and using a fan can help prevent this issue.
Step-by-step explanation:
Dust and hair can accumulate on computer fans, blocking the airflow and causing the machine to overheat. This excessive heat buildup can lead to permanent damage to the computer. Regularly cleaning or clearing the fans is essential to prevent this from happening.
One way to keep computer fans clear of dust and hair is by changing the filters regularly, following the instructions provided by the manufacturer. Filters trap dust and other pollutants in the air, so keeping them clean is important for maintaining proper airflow.
Using a fan increases the flow of air, which helps dissipate heat. Convection, the movement of air, enhances the rate of heat transfer, making moving air feel cooler than still air. This is why using a fan can help prevent excessive heat buildup in computers.
