Today I want to tell you how to clean computer dust (power supply, processor). Many people do not pay attention to this process, and as a result the performance of the system decreases and the risk of microchips overheating increases dramatically. In order not to then face expensive repairs, it is better to periodically perform preventive work.
What is a cooler?
From the English word “cooler” literally translates to “cooler”. In fact, it is an ordinary fan that provides air circulation inside the system unit or laptop. Thanks to this component, the heat is effectively removed from the heated surfaces.
I once unwittingly became a participant in the following experiment. While cleaning a laptop, I had to disassemble it to the smallest detail. In the end, I put everything together, but forgot to connect the cooler. A few seconds after turning on the PC, the thermal protection system kicked in and the computer shut down immediately.
I found out later that there is such a useful feature, which protects the hardware from overheating. By the way, not all models are equipped with such features. And if the fan fails (or you forget to connect it), the consequences can be disastrous.
Why do I need to clean it?
Over time, a lot of dust accumulates inside your PC, which reduces cooling efficiency and contributes to an increase in static charge. The temperature of of vital elements increases, a slight smell of burning appears, performance decreases, and the cooler starts working louder. As you can imagine this is not good.
I strongly recommend checking the cooler regularly (at least once every three months, or if you hear strange noises inside the case) and cleaning it from dust.
Did you know that the active cooling system can be installed not only on the processor, but also on powerful graphics cards, hard drives and even memory slabs?
How to Clean a Computer CPU
This procedure is not too difficult, however, requires increased attention to detail. If in doubt, it is better to use the services of specialists.
Here is what we will need:
- A soft, lint-free cloth;
- A small brush;
- Lubricating oil;
- Phillips-head screwdriver, tweezers;
- Vacuum cleaner;
All right, are you ready? Then let’s get started!
Disassembly and general cleaning
- Turn off the PC and unplug the power cord, which usually connects to the back.
- Using a screwdriver, unscrew the fixing screws that hold the side cover in place.
- Lay the system unit on its side so that the ASUS motherboard is on the bottom. See how much dust has accumulated?
- First we clean with a vacuum cleaner (only the power should be set to medium).
- Remove the hard-to-reach places using a brush. Be sure to wipe the surface of the board and heat sinks with a cloth, which we previously dipped in alcohol.
- How to Clean the Computer Power Supply from Dust? Use a vacuum cleaner in suction mode, bringing the tube to all accessible holes in the PSU (especially the fan side).
Cleaning the Graphics Card
You can then turn on the PC to listen to each of the fans. This will tell you which one is the noisiest (i.e., problematic). Often, the most clogged turns out to be the cooler of the discrete graphics adapter.
- To clean it, you should disconnect the board from the chipset by first disconnecting the VGA / DVI / HDMI cable that connects the card to the monitor.
- Now you can remove the cooler by unscrewing a few fixing screws. Remember to remove the cable from the power connector:
- Gently brush the fan blades to remove the dust from the grille. It can be quite intimidating:
- Try to leave fewer fingerprints on the pins and tracks. It is better to wipe the surfaces with an alcohol cloth before installation.
Every computer fan has a sticker on it, which is not just for beauty. It covers the bearings and axle.
- We remove the sticker and set it aside (don’t throw it away!).
- We put a little bit of oil on the surface with a syringe:
- Let’s put back the sticker and assemble everything in the reverse order. That is, put the fan back in place, bolt it in place, connect the power. Nothing complicated, don’t you think?
The other coolers are cleaned in the same way. But be careful that the dust blown out by the vacuum cleaner does not settle on other surfaces. I recommend going afterwards with a brush and a damp cloth to remove the debris completely.
My advice to you. If you can remove the cooling system from the main CPU, it’s best to clean it in the bathroom so you can easily rinse the debris off afterwards, rather than collecting it all over the house.
Except that to put the cooler back in place will require replacing the thermal paste. I’ve already told you how to do this, in a previous article.. But I can do it again.
- Apply a small amount of paste to the surface of the cleaned CPU and heatsink. About this much:
- Using a special spatula or a bank card we distribute the paste evenly so that the layer thickness does not exceed one millimeter.
- Carefully put the coolant in place.
You should end up with this beauty:
But what if you have a laptop from Acer or another manufacturer? How to get to the fan?
Here the situation is a little more complicated. Each model is disassembled differently, although there are common points. You can find a detailed instruction (video) on cleaning a particular device on the Internet. If you are unsure, it is better to contact a professional service.
Even I sometimes had to ask for help from more experienced computer engineers when I had to deal with members of the premium HP series.
Don’t forget to monitor the temperature using special software. >>>
If my tips on how to properly clean your computer from dust were helpful, that’s the best reward for my hard work. If you have any questions and difficulties in cleaning the coolers, you can write to me personally through the feedback form or comments. I will be glad to help!Related Posts:
