Dealing with a dusty computer

A dusty room can lead to computer problems. Dust is easily sucked into the computer case. As the dust collects, it will restrict airflow throughout the computer. The restrictive airflow will cause computer components to overheat & shorten their lifespan.

Dust prevents cool air from reaching the components that need to be cooled in order to operate efficiently. If there is enough dust in the computer’s vents it can completely disrupt the airflow needed to keep the parts cool, & will make the fans noisy due to the dust on the bearings of the fans. In a very bad situation dust can completely stop fans from working. When that happens the computer will overheat & will usually shutdown in order to prevent damage.

How to prevent your computer overheating from dusty components?

  • Clean it out regularly. Once a year unplug the computer, pop off the case, & carefully use a vacuum on reverse cycle to blow out all of the dust.
  • Keep your computer in an area that has little dust accumulation or build up. A room that is well ventilated will be less likely to allow dust to build up on your computer. When possible, get your computer off a dusty carpeted floor.
  • Cover any open peripheral slots to help keep the dust out. Be aware that some cooling slots are necessary to avoid overheating.
  • Consider installing an additional fan into your computer. You should have one fan that circulates the air to keep your computer from overheating. The second fan should blow the air out of the computer to prevent dust from settling inside your computer.
