Excessive dust in a computer can cause a variety of heat-related issues
By now, you’ve heard that the dust found in your computer could be harmful to it.
Computer requires airflow and cooling to prevent the components inside, such as the processor, hard drive, memory and graphics card, from overheating. Fans are the most common method of ensuring your computer gets enough airflow, and in turn, stays cool.
However, fans also move dust particles through your computer in addition to the cool outside air. If left long enough, the dust moving through your computer can build up on the fan and other components. When this happens, the dust acts as an insulator, which causes the components to run hotter than they normally would. And overheating is one of the most dangerous things you could allow your computer components to do because it significantly decreases your computer’s lifespan. Bring it in, let’s take a look inside.
Dust that blocks a computer's intake and exhaust vents prevents cool air from entering the computer and hot air from escaping. Dust on the blades of a cooling fan causes friction, creating noise and preventing the fan
