In one of the past articles, I already wrote, how to clean the laptop from dust, if this is what you need, just follow the link. The information set out here refers to a stationary PC.
Main Cause Noise - Dust
Gathering in the case of a computer dust is the main factor affecting the fact that he is noise. At the same time, dust, like a good shampoo, acts immediately in two directions:
- Dust accumulated on the blades of the fan (cooler) can cause noise by itself, because The blades are "rubbed" about the hull, can not rotate freely.
- Due to the fact that dust is the main interference of the heat to the heat from such components, as a processor and a video card, the fans begin to rotate faster, thereby increasing the noise level. The cooler speed on most modern computers is automatically adjusted, depending on the temperature of the cooled component.
Which of this can be concluded? It is necessary to get rid of dust in the computer.
Note: It happens that the noise of the computer that you just bought. Moreover, it would seem, there was no one in the store. Here the following options are possible: you put it in such a place where the ventilation openings were blocked or at the heating battery. Another possible reason for noise - some wire inside the computer began to touch the rotating parts of the cooler.
Cleaning a computer from dust
Accurate answer to the question of how often you need to clean the computer I can not give: in some apartments where there are no pets, no one smokes the tube in front of the monitor, the vacuum cleaner is used regularly, and the wet cleaning is a familiar action, the PC can remain clean for For a long time. If all of the above is not about you, I would recommend to look inside at least once every six months - because the side effects of dust - it is not only noise, but also spontaneously turning off the computer, errors when working with the overheating of RAM, as well as a general performance reduction .
Before proceeding
Do not open the computer until you turn off the power and all wires from it - peripheral cables connected monitors and televisions and, of course, the power cable. The last item is required - do not perform any actions to clean the computer from dust with the connected power cable.After this is done, I would recommend to transfer the system unit into a well-ventilated place, the clouds of dust in which is not very scary - if it is a private house, then the garage is suitable, if the ordinary apartment is suitable, the balcony can be a good option. This is especially true when there is a child in the house - he (and no one) should not be breathing in that it accumulated in the PC building.
What instruments need
Why am I talking about clouds dust? After all, in theory, you can take a vacuum cleaner, open the computer and remove all the dust from it. The fact is that I would not recommend this method, despite the fact that it is fast and convenient. In this case, there is a chance (albeit small) the occurrence of static discharges on the components of the motherboard, the video card or in other parts, which does not always end well. Therefore, do not be lazy and buy a sprinkled aircraft (they are sold in stores with electronic components and in economic). In addition, arm yourself with dry napkins for wiping dust and cross screwdriver. Plastic clamps and thermal passes can also come in handy if you are going to come to the case seriously.
Disassembly computer
Modern computers' enclosures are very simple in disassembly: as a rule, it is enough to unscrew two bolts on the right (if you look at the back of the system unit and remove the lid. In some cases, no screwdriver is needed - plastic latches are used as the attachment.
If on the side panel there are some parts that are connected to the power of the part, such as an additional fan, then you will need to disconnect the wire to completely remove it. As a result, you will be approximately what is in the picture below.
In order to facilitate the cleaning process, all components that are easily removed are RAM RAM modules, a video card and hard drives, should be disconnected. If you have never done anything like this - nothing terrible, it's pretty simple. Try not to forget what and how it was connected.
If you do not know how to change the thermalist, then I do not recommend removing the processor and cooler from it. In this instruction, I will not tell about how to change the thermal chaser, and the removal of the cooling system of the processor implies that then it is necessary to do this. In cases where it is simply required to get rid of dust in a computer - this action is not necessary.
Cleaning
To begin with, take a squeezed aircraft and clean all those components that have just been removed from the computer. When cleaning dust from the camcorder cooler, I recommend fixing it with a pencil or a similar object to avoid rotation from the air flow. In some cases, use dry napkins in order to remove dust that does not blown out. Carefully rectify to the video card cooling system - its fans can be one of the main sources of noise.
After with memory, video card and other devices, it is possible to go to the housing itself. Carefully rectify to all the slots on the motherboard.
Also, like when cleaning the video card, cleaning the fans from dust on the processor cooler and power supply, fix them so that they do not rotate and use compressed air to remove the accumulated dust.
On the empty metal or plastic walls of the case, you will also detect a layer of dust. You can use the napkin in order to remove it. Also note the lattices and slots for ports on the case, as well as the ports themselves.
At the end of cleaning, return all the components taken into place and connect them "as it was." You can take advantage of plastic clamps in order to bring the wires in order.
Upon completion, you must get a computer that looks inside as well as new. With a lot of probability, it will help you solve the problem with noise.
The computer rattles and buzzing strange
Another common cause of noise is a sound from vibrations. In this case, you usually hear a rattling sound and can solve this problem, making sure that all the components of the housing and the computer itself, such as the walls of the system unit, the video card, the power supply, the drives for reading the discs and hard drives are securely fixed. Not one single bolt as it often has to meet, but a complete set, by the number of mounting holes.
Also strange sounds can be caused by a cooler who needs lubricant. How to disassemble and lubricate the cooler fan bearing in general terms you can see in the diagram below. However, in new cooling systems, the fan design may differ and this manual will not fit.
Cooler cleaning scheme
Fascinated hard drive
Well, the last and most unpleasant symptom is the strange sound of the hard disk. If he previously behaved quietly, and now he began to crack, plus you sometimes hear how it makes it a click, and then something starts to buzz weakly, gaining speed - I can upset you, the best way to solve this problem is right now go for New hard disk while you have not lost important data, as then their recovery will cost more than a new HDD.
However, there is one nuance: if the described symptoms take place, but they are accompanied by strangeness when the computer is turned on and off (it does not turn on the first time, it turns on when you turn it into a power outlet), that is, the probability that the hard disk is still all right (True, as a result, it is possible to turn it so much), and the reason - in problems with the power supply - insufficient power or gradual output of the BP is out.
In my opinion, it mentioned everything as concerns noisy computers. If I forgot something, celebrate in the comments, additional useful information will never hurt.
