It seems that everytime i look inside my case there is dust. I try to keep it clean useing "Dust off". I heard that ur fans can be the cause of this. Can someone please explain this a little more, on how to prevent/minimize dust in ur case.

Filters will help to some extent. I believe that you want more fans blowing in than out. Reason being that when you have more exhaust than intake the air needs to come from somewhere. That means it will sneak in through any crevice that it can find. What you really want is the air to come in through your intake fan. This is better for airflow plus you can control dust better with a filter.

A clean room would help as well. ;)

My room is pretty dusty (rez, dirty carpet) so everytime I open up my case it's dust inside. :( Don't want to use a filter cuz that cuts down the intake cfm. I guess I'll be doing my regularly cleaning for a while. :eek:

Watercool your system, have cpu, gpu, and Northbridge watercooled, get a fanless gpu, and no dust will come in because there is no airflow, the only fan should be the radiator fan, which you make external.

Positive presure without input side filters will not help. Dust is airborne and will get in thru the fans providing the presure.

Positive presure with the input side fan filters installed, will help because then there is no unfiltered air to come in thru the many small holes and cracks. Instead it will go out thru those cracks.

If there is negative presure, then there is a flow of unfiltered air through those uncontrolled secondary holes.

positive pressure....

more fans (CMF's acctually) blowing out, than fans blowing in.

This is a bit of a misconception that is quite common, this won't do anything but MAYBE control where the dust is . Unless you use filters, then its a great way, but you still have maintainance. (Just like Startech said... lol didn't notice)

Really the BEST way to keep dust out is filters, however this makes it a lil louder usualy, requires maintainance and restricts airflow.
As for watercooling, it won't really fix your problem because you SHOULD still have some case fans (though you could probably get by withough but it would be tough), though if you use fans that push less CFM it will definatly make dust accumulate slower. Also not smoking (if you do) inside and not having pets would help a bit, and vacuming a lot and such...

also with WC you can use the filters with less worry, as CFMs don't matter quite as much, and the noise will be less as the slower moving air from the 12cm fans that most people use will not cause noise when sucked through filters like the faster moving air from smaller case fans

Yeah, filters are the way to go, at least when you can. It's harder to find a good looking filter for my window-mounted 120mm fan though, so I have to clean fairly often.

Ive tried alot of different things over the years on this ghetto/frankenstein case.

I finally settled on panty hose as the best washable, replaceable filter.

Ive got a 120mm fan in the front and one on the side.

I cut the size I need, affix to the fan and away I go.

you cna always ghetto it by getting panty hose nd putting them around the fan. I do that for friends who have tons of dust in the pc, it works great!

Take all of the fans out. :)

Actually, I don't know what forum it was on, but something from Shaper Image was able to remove all of the dust INCREDIBLY well in a huge room, look it up.

One of those ion fans or whatever they are called perhaps? No moving parts as I understand it and they attract dust AND move air at a decent rate from what I have seen...
