    I do not know if this is the right thread, but I guess you people would be the best as it can be related to cooling, i.e. fans.

    I get allot of dust into my pc, I don’t know if this is normal. I tried to search the forum, but had too many results.

    Can you please post a link, of tell me if this is normal, or what am i doing wrong.

    I have two fans on the back, air out.
    One at the front air in

    Can it be my room? I have a small room, and I get allot of dust around my work area.

    Getting dust in your PC is something that is difficult to avoid, but if you let it build up for a long time, it can cause all sorts of annoying problems. It gets in the fins of heatsinks and clogs them up, reducing cooling capacity. It also finds its way into empty expansion/RAM slots and that can cause problems if you plug something in without cleaning the slot first.

    You can pick up cheap dust filters from eBay and other online stores, which might help to solve your problem. You could, of course, fabricate your own dust filter from a piece of thin foam taped over the vents, which I find works quite well on holes in the case that don't have a fan behind them.

    I have this problem here in New Mexico. Everywhere I look there is dirt and dust storms are always shutting down the highways. If I leave something out for 5 minutes it will coat with dust and the computer needs a weekly compressed air spray, even with 1 120mm on a radiator and 2 60mm outtakes. Once I thought I fried something on my video card, when it was simply a dust build up. My newest solution has been to spray it with compressed air with the vacuum on to catch all the escapees. Those dust filters don't work really well, since the dust is everywhere.

    That link makes Ariel cry :(

    I thought i had it bad. I was just thinking how does it get in. Well i mean before i only had two fans blowing air out, so nothing was blowing it in!! I guess if air is going out, some has to get back in from somewhere, and this place is bringing in dust.

    Anyway whats the best type of filter to use? besides freshner wipe

    Exactly. What goes out must come in. I think the dust accumulation may have something to do with static electricity as well.

    Filters won't totally eliminate the problem as the filter will clog up and will diminish air flow just as if it were in the heatsinks themselves. But at least there will be less dust within the case to get into bad places. The filter just collects the dust in a location that is easier to remove

    There are filters out there that attach like a fan grill, they are usually a tight nylon mesh. But there are some that use sponge as well. If you go this route try to create positive pressure within the case, i.e. have more fans w/filters blowing in than that are blowing out. This way there will be clean air blowing out all the seams and holes rather than sucking in unfiltered air. Also you dont need filters on the fans that are blowing out. Remember though that a fan with a filter on it will move less air than one without. And as the intake filters start to clog there will be an increasing rise in negative pressure. A way to ensure always having some positive pressure is to only have fans blowing in, and just leave empty holes for the air to escape.

    A good way to check for possitive pressure is to hold a lighter over the seams and little holes and see which way the flame leans. I use this method to check for neutral pressure, which is where air flow is maximized.

    If you leave the computer on all the time you won't need fan filters on the exhausts. But you might if you turn them off as static electricity will attract dust, which will go through the exhaust fans that aren't spinning!
