Death By DustSaturday, December 3rd, 2011
When we repair a computer at my PC Techs, one of the first items on our list of work to perform is dust removal. In Arizona, dust is a big problem and coats everything. When a new computer comes into our shop we never really know just how much dust we are going to see! It’s always a surprise when you “pop the case” of a computer for the first time.
Here are a few pictures of the inside of a case that recently came into our workshop.
Dust is a slow computer killer. Dust prevents normal air circulation through the computer case. The case draws cooler air from outside the case through the various airflow openings of the case. The lack of circulation caused by dust will often result in internal component overheating and failure. These include video cards, hard drives, computer processor and other internal hardware.
Common intake openings of the case include the front and the sides of the case, while exit openings include fans usually mounted in the rear of the case and the power supply.
Keeping these openings clear of debris can help to maintain the proper airflow around the case. A good practice is to also maintain four to six inches of clearance from the computer to any object which could block airflow.
In conclusion, dusting out your case every month can help to extend the life of your computer – instead of it suffering the fate of death by dust.
