Was browsing at the local computer store (altex), its like a fry's, but a bit smaller.

They had these really neat 3 part filter systems for computer fans. Its a mounting plate, a filter, and a filter retainer plate. All made of plastic (except the filter). You unscrew any intake fans on your computer, and run the screws through the mounting plate, through the case, and into the fan. then the filter fits inside the filter retainer, and the retainer snaps on to the mounting plate (its an easy-on, easy-off deal). After running them for a week, I was surprised to find the amount of crud that the filters caught. Lots of dust that wont end up on the inside of my computer case.

their website is www.altex.com , and the filters are only about $4 for a set. They make them in a couple different sizes, so it doesnt matter what size fan you have. Very handy indeed, for those of us with clear cases who like to show off the inside of their cases!

Thank goodness you stopped that from all the moving parts...all the grit and such would be horrible!!!

Does K&N make a filter for it? Will SLP have a lid?

Well, since there is more restriction on the intake, its a good thing my computer came with low restriction exhaust!!!

Seriously, dust can be quite a problem. I run my computer in environments that are very high in metallic particles in the air, and metallic dust can accumulate over time and short out parts of the board. The dust can also accumulate and act as a thermal insulator (preventing necessary heat transfer for appropriate cooling). Since my main board just blew out due to overheating, this is something i am a little concerned about.

I have applied some fluid mechanics and heat transfer principles to my computer case. I have 2 intake fans, and 1 exhaust fan (the exhaust fan is part of the power supply). The dual intake fans provide more filtered, cold air than 1 fan, so i increase the amount of cold air entering the system in a given unit of time. This in turn allows more heat to be removed from the computer case environment in a given amount of time than before (when i had only 1 intake fan). This should lower the internal temperature of the system, but i will be testing it later this week when i get back to school, where i have my digital thermometer probe.

In addition, the fact that I am bringing in more air through the intakes than I am releasing through the exhaust would normally mean a pressure buildup inside the case. But, since the case has holes in it (and nothing is sealed), airflow is constantly equalizing itself, i.e. air is flowing OUT of all the holes in the case. This means that no outside contaminants can enter the case (or else they would have to be traveling against the airflow at the holes and exhaust port). This means that the only place where air is entering the system is the intake fans, and those are both covered with filters.

So, I not only end up with a lower internal case, board, and chip temperature, which should help prevent future burnouts, but I will also reduce the dust that gets into the system. This will help keep mechanical parts like CD rom and floppy disk drives free, so their mechanical parts will continue to work. Also, it will keep my unused PCI connections cleaner for future upgrades, and keep insulatory buildups of dust from collecting on the CPU fan and heatsink.

Metallic particles can wreak all kinds of havoc on tightly packed electronics today. I remember a few years back when some of the hardware guys where I work started talking about "zinc whiskers" causing shorts and I thought they were kidding at first, but they assured me it was a real issue.

Any of you guys ever hear of zinc whiskers(pdf file)? It's kinda interesting.

At least I am consistent!!! [Big Grin]

Unfortunately, i now do stuff like this without thinking. I am an "instinctual dork".

SOMEONE HELP ME!!!!!!!! [Razz]
