Controlling dust ...inexpensive.....

by John Robie - 4/21/04 8:42 PM

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.
