Cheap Homemade Computer Fan Dust Filter - Part 2

(This is the continuation of Part 1)

  1. Light a candle and affix (hold and lock) a 2-inch nail to a pair of vise grips. Put a cardboard or newspapers to prevent damaging your work surface or table.

  2. Heat the pointed end of the nail on the flame of the lighted candle for 2 minutes or more as shown below.

  3. While holding the plastic lid, pierce the marked points with the hot pointed end of the nail. When hot enough, the heated nail will melt the plastic and create a hole.

  4. Ensure the created hole is big enough for the air-intake fan's screw to pass through. You can make the hole bigger by wiggling and rubbing the heated nail sideways through the plastic. Reheat the nail on the candle flame as necessary.

  5. Remove the cover panel of the computer case. You may have to use a Phillips screwdriver to do this as well as to remove the air-intake fan.

  6. Position the plastic lid over the air vent holes. Ensure the holes are aligned. Insert the screws so they freely pass through the holes of the plastic lid as well as that of the cover panel.

  7. Choose an object whose size and shape approximates that of the set of air ventilation holes. For a round shaped pattern, this could be a coaster, drinking glass, cup, saucer or even another plastic lid.

  8. While holding the object, trace the shape on the clear plastic lid with a pen marker.

  9. Here's the clear plastic lid with the drawn shape (a circle in this case). Notice the circle does not touch the screw holes.

  10. Create a pilot hole inside the drawn shape. Use a sharp knife, cutter or razor blade to create a small triangle-shaped hole.

    Again, cover your work space with a cardboard or newspapers to avoid damaging the surface.

  11. The size of the pilot hole should be big enough for the the blades of a scissor to enter and start cutting.

  12. Using a pair of scissors, cut out the drawn shape as shown below.

  13. What remains of the plastic lid will become the computer fan dust filter frame for the screws.

    Position the frame over the air vents. All the air vents should be exposed inside the frame.

  14. Take the plastic tub. The plastic tub's mouth or opening should be just a little bit bigger than the cut hole you just created on the computer dust fan filter frame.

  15. Measure two centimeters from the rim with a ruler and a pen marker. Mark a few points around the plastic tub.

  16. Take a roll of masking tape and tape around the plastic tub covering the marked points.

    This will ensure that the top edge of the masking tape is at least two centimeters away from the rim.

  17. With a sharp knife, cutter or razor blade, slice and cut the plastic tub with the top edge of the masking tape as guide. Be careful when handling very sharp tools.

  18. The result is a short tube that will be attached to the computer dust fan filter frame. The length of the short tube, which is two centimeters, would provide adequate distance to keep the filter material away from the vents. Remove the masking tape.
