Protection from dust of the system unit. How to make a dust filter for your computer with your own hands? ⇡ Internal structure

Dust is one of the main enemies of computers and laptops. It is this that clogs the fan, settles on important “internals”, including the processor, preventing them from cooling, which is common cause breakdowns. This can be combated by periodic cleaning. system unit, "stuffing" of the laptop from dust. However, this is a very tedious process: you need to disassemble the device, blow it out from the inside with a vacuum cleaner, and clean some parts manually. Therefore, many turn to another way out of the situation - a dust filter for the computer. We will discuss with you both purchased options and those that you can make yourself.

Why is dust dangerous?

As we have already mentioned, the accumulation of dust inside leads to overheating of system elements. And this is fraught with the following:

The fan speed increases. And this is not only extra noise, but also the reason for its rapid breakdown - the mechanism begins to work at the limit.
Capacitors fail motherboard, power supply, video card.
Trying to protect the processor from overheating, the system activates a mechanism that reduces its performance. This leads to annoying freezing. And in emergency cases, when the heating of the processor reaches a critical stage, the computer turns off altogether.
Dust can cause short circuit, static breakdown to the microcircuit.

All of the above requires serious repairs, which will obviously be more expensive than a dust filter for a computer, even a purchased one. Why it is so useful, we will consider further.

What makes a computer dust filter stand out?

What you will find in stores is a canvas made of a special air-permeable material with some options for attaching to the case of a system unit or laptop. Manufacturers of dust filters for computers in Minsk, and many other cities, promise potential buyers the following:

Long years of product service.
Almost 90% air filtration quality.
Little air resistance.
Adjustable size and shape. In most cases, a large roll of canvas is sold, from which you can independently cut a dust filter for a computer 120 mm x 170 mm or other sizes you need.
Easy installation - basically the back side of the material is adhesive, so it is quite easy to install it on the system unit.
Additional sound absorption.
Protection against insects getting inside the device.

What does the protective fabric provide?

In general, all dust filters for PCs and laptops are required to provide the following:

Reliable protection of the “filling” of the case from dust.
Stable low processor temperature (and it does not heat up so much from high performance, how much from the dust that has settled on it).
Long-term operation of components, ensured by almost ideal conditions inside the case.

What types of dust filters are there?

It turns out that protective sheets also differ in their main function. Let's look at their varieties using the example of dust filters for the Samokleikin computer, according to the manufacturer, developed on the basis of patented technology. There are three types here:

Fine cleaning. Material: open cell polyurethane foam. Filtration efficiency is up to 90% - the canvas is capable of retaining dust up to 5 microns in size. This allows you to achieve ideal cleanliness inside the system unit.
Long service. Material - non-woven fiber polyester. It provides both excellent filtration and good dust holding capacity. This canvas helps the computer for a long time without maintenance.
Low resistance. Material: woven polyester mesh. It allows air to pass through itself better than others, which helps it have a minimal effect on the temperature of the processor case. A few more features of the filter: protection against insects, the ability to install on a laptop, netbook, between the fan and the case.

Installation options

It is possible to install two filters at once: long service and fine cleaning. The first one will capture large dust, the second - fine dust. Thanks to the large capacity of the long-life canvas, the fine cleaning barrier will concentrate on collecting small particles, while causing minimal contamination.

Cleaning the filter

It goes without saying that the cleaning cloth will become clogged with dust and become dirty over time. Of course, you can remove the old filter and replace it with a new one. But it’s not difficult to clean it:

The easiest and most gentle way is to vacuum it without removing it from the computer. This way you won't damage the adhesive layer.
More serious cleaning involves removing and rinsing in warm water. Next is natural drying. In some places the adhesive layer will withstand such a test, in others you will have to install a new one. Not all filters can be washed in a machine, with powder or soap. Dust can be easily washed out by simply rinsing in water.

And now we’ll move on to how to make dust filters for your computer with your own hands.

Homemade protective barrier

It is unreasonable to overpay for something that you can easily and quickly find and make yourself from scrap materials. In addition, dust filters for computers are not available in every office equipment store - you will have to spend time ordering and go around a lot of places to find them.

We will present you the most reliable and uncomplicated options:

It is attached to the fan itself, which cools the processor, inside the case. More precisely, first a wire arch is installed on the mechanism - so that a piece of a woman’s stocking does not get sucked into the blades. The canvas itself is secured with plastic ties.
Inner layer of a medical mask (for the power supply housing). It is attached with wide tape (it is best to use reinforced tape) on top of the fan grille - you just need to cut out a sheet of suitable size.
Medical gauze. Best used for vertical blower power supply. You can secure the material with regular stationery tape. It is also important to cover all cracks and holes with adhesive tape so that dust does not pass through them and bypass the filter.

Such improvised means protect both the fans and the “filling” of the system unit from dust getting inside just as well as store-bought means. You can also use synthetic padding for additional protection, but no more than three layers - a denser concentration will complicate air exchange.

Before you make a dust filter for your computer and install it, check out these useful tips:

Do not use materials that are too dense in the hope that they will definitely not allow dust into the computer. This will make the situation worse: air exchange will decrease, which will contribute to overheating. Before using this or that fabric, conduct a small effective test - try to breathe through it yourself. If it's easy, then the material is good.
Consider installing the filter so that it cannot get into the fan blades and block its operation. This may result in the device breaking down and requiring replacement.
If possible, reduce the cooler speed. But to a reasonable point. Everything is simple here: the less air it moves, the less dust settles.
The reduction in air flow can be compensated for. For example, by installing improved thermal paste.
Zero filters from auto stores will work as a material for a protective barrier.

Protecting the “filling” of the computer from dust is a guarantee of long-term operation of the device. Special dust filters will help with this, which you can either buy in stores or make yourself from scrap materials.

I attached a mosquito net to the windows, after which the material remained and the idea for its adaptation arose.

We make a fan filter in 10 minutes and almost free

I have moved this article from the old DNS blog (which will be closed soon) and updated it to the current state.

Just yesterday I carried out a global cleaning of the system unit. I bought a bottle of compressed air and, having disassembled the entire SB (system unit), began to get rid of dust, at the same time replacing the thermal interface on the processor. Thanks to the “Accordion”, which I wrote about earlier, my video card always remains clean inside due to the presence of a mesh filter inside the air duct. Yesterday I had an idea about closing access to dust. Naturally, I decided to buy filters for coolers and stopped there.

Today, while working with the mesh, I remembered what happened yesterday and decided to use the leftovers for filters for fans.

So, I’ll briefly tell you the manufacturing principle.

Take a sheet of paper. Preferably from a sketchbook - they are slightly thicker than ordinary A4 sheets for office equipment, which will allow the future filter to be more rigid.

Next, cut out the squares. For one filter you need 2 of these. The size of the squares depends on the fan. If we have it 80x80, then we make the paper square 90x90 in size. We extend the filter so that after cutting out the circle we have some paper left on the sides, i.e. a kind of “stiffening rib”. Then we mark the center of symmetry of the square (I hope that everyone attended geometry lessons at school and knows what it is). From this center we draw a circle with a radius of 38 mm. This number was taken to make the filter more resistant to wear. Then we cut out the circles. It turned out to be 2 square bagels. We praise ourselves for such incredible confectionery products made according to my recipe, and continue further.

Then we cut out a mosquito net to the size of the paper (I bought it in the store for 50 rubles per 1 meter). And we cut off small corners so that the identical halves of the paper stick together well. We coat each leaf, put nets between them and glue them together. Iron it a little and dry it. All this should go well if you are in kindergarten did not skip application classes. When the structure is dry, we place a fan on the filter and mark the locations of the holes for the bolts, and then cut them out.

For fans of other sizes, the manufacturing principle is similar, but with changed dimensions. The basic algorithm has already been outlined.

Afterwards, you can paint the paper any color or the color of your computer case. Filters can now be placed either between the valve and the housing, or behind the housing and behind the fan. The first option is preferable, because in this case the cooler will not become dirty. I put the filter on the “Accordion” outside.

Here's what I got:

Conclusions about the work done:

Pros:

1.Cheapness. A regular filter costs from 50 to 100 rubles. Ours is almost free, considering that the mesh is purchased for a window. But even if you buy a mesh specifically for filters, then when converted to one filter the amount will be ridiculous. It's actually free.

2.Fast. It took me 10 minutes to make one filter. I made 2 filters. The second one was for a cooler measuring 120x120. Previously, this cooler had a garlic bag mesh on it. There is a mesh with a larger mesh and it stopped dust very well. The cooler was in almost perfect condition.

3. Efficiency. Store-bought filters are denser and do not allow air to pass through as well. Our filter allows air to pass through better, stopping dust.

4. Compactness. The filter is very thin and can be placed anywhere.

Cons:

1. Not identified

2.Not detected

3.Can't be felt

4.Not visible

I hope my experience is useful to someone.

Advanced users need to regularly look inside the system unit to replace components with newer ones, add a hard drive or a new expansion card. When you open the lid, it becomes immediately clear whether the owner of the computer is watching him. If there are large clouds of dust and they try to get into the respiratory organs, this is not very good. Some people may have an allergic reaction to particles of dirt and dead skin.

When particles rub against each other, they can accumulate static electricity. If there is a short circuit on the motherboard or other board, it is quite possible that it will fail.

1 way of protection: expensive

To prevent dust from getting inside, you need to buy a system unit with removable dust filters. Usually they are placed on the front of the case from the bottom (sucking cool air into the system unit). Then it all comes down to rinsing them with water once every week or two and putting them back (after drying them first). This is the most effective and beautiful way to reduce the amount of dust inside your computer to an insignificant mass.

Any modifications to the housing without removable filters will not look harmonious and will not be as functional.

2nd method of protection: improvised

If you have an old building and you don’t want to invest in updating it, or spend money, then take a regular medical bandage (every family should have one in their first aid kit). Fold it in several layers and attach it to places where air is sucked into your computer. It won’t look very good, the functionality won’t be great either (since the bandage allows most of the dust through), but it’s fast and free.

3 way of protection: functional

There are special adhesive-based filters, for example, Samokleikin. This is the same material used by case manufacturers. One side of the filter is attached to the hole in the system unit. It is important:

It is necessary to clean the surface from various contaminants
Make sure that the surface is flat (you can’t glue it to the corners, as it will fall off over time)
You need to press not with your entire palm, but with one finger over the entire area (for greater pressure per unit area)

Dust is one of the main enemies of your computer. No matter how much we monitor cleanliness, no matter what we do, dust is still drawn from the air by the computer, preventing it from working, and causing you to constantly sneeze.

website I have collected tips on how to easily clean your computer from dust and dirt using available tools.

1. Wipe the screen

Do not use products containing alcohol, ammonia or acetone. These aggressive liquids can remove paint from buttons and can easily damage the screen, especially if it is equipped with an anti-glare coating.

To make an all-purpose cleaner at home, mix equal parts water and white vinegar. Use this solution to lightly dampen (not dip!) the cloth you use to wipe down your computer.

3. Getting rid of scratches

Debris and dust from the keyboard can be easily removed using a regular
