Computer Dust Problems

Dust is by far the main cause of PC and other electronic hardware malfunctions and failures. In fact, it’s proved to cause more than 70% of all hardware performance issues - directly or indirectly. Why does this happen?

Most computers are designed to use a combination of vents and cooling fans to keep the internal components operating at a safe temperature. While dust on the outside of your computer case can’t cause much damage, when dust is drawn into the vents they can begin to clog.

When the vents clog, the fans must work harder to keep a safe temperature. Additionally, dust that settles on the inside of your computer has insulating properties that block proper airflow. Like any mechanical part, the harder those internal cooling fans work, the faster they will break. If the fans can’t maintain a safe temperature, other parts of your computer like the memory, processor or power supply can overheat and stop working correctly.

Processor throttling slows down a computer (more specifically, its processor) to use less power and avoid overheating. Therefore, due to dust building up around the processor, the airflow within the cabinet is hampered and the parts become hotter than usual. If throttling doesn’t help drop the temperature, various components shut themselves down to avoid getting fried due to excessive heat.
