Heat. It shortens the life of your PC. That's why so much attention is paid to cooling your system. Fans draw air in and force it out of your PC, allowing it to flow over the chips and heat sinks in order to keep things cool.
Dust. Unfortunately, the cooling fans also suck in dust and dirt. It clings to every electronic component in your PC and prevents air from flowing across the chips. Instead, the air flows up and over the dirt, allowing heat to build up in your PC.
The photos on the right show a six-month-old Core2 Duo PC used in a home office. Not much cooling going on in this PC, especially in that high end video card. When the owner complained that his computer kept crashing, we cleaned it out and put it into a Clean-Aire™ Computer Enclosure. It hasn't crashed since.
You won't find much written about dust and dirt in PCs. But, we've all known for many years what it can do to a computer. Read the article by Larry Mingus, "Computer Dust - Should you worry?", written in 1998. He put the issue in perspective many years ago.
But, what most people don't tell you is that computer dust can be toxic. Lead, Mercury and Cadmium are used in the manufacture of computers, and are highly toxic. When dust is introduced
into the PC or Server, toxic chemicals can attach to the dust and then be exhausted into the air.
This is why we cringe when we see videos on how to clean a dirty computer. These videos show someone just opening up a computer and blowing it out with compressed air - inside their home or office. No breathing mask, no dust cover, no ventilation. This is just plain irresponsible.
The proper way to clean a dirty computer is to put on a breathing mask, take the system outside and use a can of compressed air to blow the dust out. We also recommend that you use a HEPA vacuum cleaner to capture as much of the dust as possible. You can also remove the video card, CPU heat sinc and other dirty components and blow them out separately.
But you can prevent the build-up of dust and prolong the life of your PC with Clean-Aire Computer Enclosures. Let the dust and dirt build up in the filter. Then just clean and replace the reusable K&N Filter. It's that simple. But, don't clean your filters too soon. Even with all the dirt built up on the filters below, air flow was not restricted.
As you get to know your filters, you'll see that they are unlike any other filters on the market. And you'll be amazed at how much dirt they stop from piling up inside your PCs and Servers.
