Controlling dust ...inexpensive.....

by John Robie / April 21, 2004 1:42 PM PDT

Due to room layout and furniture, my 3 computers are not 36 inches off the floor but 3 inches off the floor. Learned after my 1st computer some time ago about it collecting gobs of dust inside even after cleaning every month or so. Light bulb lit up inside brain....ah... how do air conditioners/furnaces handle it. Look at the back of your tower, normally there is a blank perferated area which looks like a fan should go there, or maybe there is a fan there other than the fan of the power unit. Go to your friendly electronics/computer store and buy a fan guard (aprx $1.35), bend the pegs out for attaching screws leaving enough space to put in a filter cut out from an air conditioner/furnace filter. If you don't have a fan there, buy one for aprx $12 or less, installing it so that air is being blown into the case sucking through the filter. Don't worry about the numerious other holes in your case for ventilation. Somehow it seems that dust tends to not intrude where there is even just a slight breeze flowing out. Just that one fan blowing in filtered air will surprise you on how clean your insides remain. If you have other fans pulling in outside air install a fan guard and filters on each of them.

OK, so you don't have any way that a fan can be mounted on the rear of the tower. Do like I did with one of mine. Cut a circular hole in the side of the removable case being careful for where the screw holes will be and then use double fan guards for holding the filter. Ah..find out the power cord is too short..can buy cord extension and also Y connections.

USE YOUR GLUE GUN
by nworley / April 24, 2004 7:33 AM PDT

John:

If you purchase a hot glue gun ($1.00 at Dollar Store) and just tack your filters in place, then they can be replaced very easy. The beauty of the hot glue gun is that you can peel the glue off anytime you choose. You can tack them inside of your panels with the air holes and it has a secondary effect. It will muffle some of the noise.

Leave Dust and Forget About It
by pfeffer3 / April 24, 2004 11:58 AM PDT

I asked a man who had done 20years in US Airforce with computers, and then a stretch with IBM, and now has a computer repair shop to fight off retirement boredom, and he said forget about dust. "Start stirring it up and get it jammed in between connections."

Will you let the dust build for twenty years or so?

I had a computer that I thought had gone totally South. On boot up it would go so far and ask for an installiation disk and then would not recognize the CD. I decided that it couldn't hurt to open the computer and check the connections before taking it to the repair shop. When I saw all the dust on the outside grills and inside, I decided to vaccum. The vaccum removed gobs of dust. Then tried the boot up and everything worked like a charm. Now my motto is "When all else fails--clean".

Just what I have suspected for sometime.
That DUST really DOES cause problems.
Hats off to you for taking a looksee and spotting all that dust, and it must have felt great to have your computer working again.

Hey... why not just tape a filter over the fan intake?
No cost or screwing-on... easy to remove if filter is washable. Tape is cheap!

OOooops... I forgot to caution all you retired USAF vets (like me)... when putting a filter over your air intake,,, be doggone sure it has a good enough flow capacity, or your doggie will overheat!
The urethane foam (not too dense) will work for that, and you can cut it to any shape or size. I use one in my CPAP.
Good luck!

Will the thin, (1/8" to 3/16" thick, 99-cent, foam filters like Home Depot has work okay? Dust is a major problem where I am & I want to protect my first-ever computer, but I am concerned about using the wrong thing & overheating it.

I worked in communications in the Army for 18 years, and keeping inside of electronics equipment is VERY IMPORTANT, while the dush insulates and keeps the heat in, BAD IDEA!! An inexpensive and efficient filter can be made from an old pair of ladies nylons stretched over a kitchen scrub pad, the flat rectangular green or blue kind made of plastic, then tape it over the air inlet. It doesn't restrict the air flow, and the nylon mesh is an excellent filter media.

Well, I went the more elaborate method. I work for a filter factory as a machinist so I couldn't do anything the easy way. I doubled up and put a second case fan on the side to pull more air in and so it would pull it easier thru the filter mentioned below. Then made a little bracket to mount a piece of redi-bolt to so it stuck out about 4 - 5". It looks like an air filter mount on an old car engine. I cut a piece of 1/8" plexiglass into an 8" circle, hole in the middle for the redi-bolt and a wing nut. Then I searched Wal-Mart for the right size air filter. I found a Fram CA148 for 3 or 4 bucks. I'm a gearhead (car lover, do it yourselfer) an it looks kind cool. I can feel the air flow into it when I put my hand on it. Works great!! So I can blow it off periodically or toss it for a new one when I feel the need. Hope this helps someone who wants to do it the hard way.

Thanks John - sounds good

When I go to pick up a power protector, I shall ask for a fan guard, and filters. I am sure I will find a way to install them.

Or go to www.microsoft.com/at home/more done/cleancomputer.mspx either way you people run the risk of doing more damage with creating a static charge with a can of dust off or with our own box and a fiberglass furnace filter. Our product has over two years of R&D it is the lowest cost and best in its class. The powers that control the internet do not even list this site on the front pages of any major search engine because our competitiors pay for the spots and they charge more money. Certainly relevency is determined more by credit reports than the quality and vision of the product. So time is of the essense those of you who are searching for the knowledge you will find the links page and the depreciation and maintenance scheduals for an industrial user helpful evaluating the economic worth of such a positive displacement computer filtration system. At our site you can weight the costs and benefits of the main manufactured products that provide such dust filtration. The links and the photos and attributes of each primary competitor is there.
