About the problem of computer noise, how to fix the problem of computer noise

The noise of the computer mainly comes from the fan, and many materials have introduced the method of filling the fan with oil to reduce the noise, but the author believes that the noise of the fan is not necessarily due to the lack of oil in the bearing. The "eccentricity" of the fan's blades is the main cause of the noise. High-quality fans, the center of gravity of the fan blades on the axis, the operation is very stable, the noise is very small, and the inferior fan, there is often a certain deviation, the center of gravity of the fan blade does not cause "eccentricity" on the axis, such a fan rotates, it is equivalent to an oscillator (the oscillator is to add an eccentric wheel on the motor shaft), with the use of time, the fan bearing gradually wears, or the fan heat sink is not firmly installed, loose, etc., will make the vibration aggravated and the noise becomes larger.

The simplest solution to this type of failure is to install the fan as firmly as possible so that it cannot vibrate, of course, this method does not solve the substantive problem, because the fan blades are still "eccentric"; Another method is to inject oil into the fan bearing to cushion the vibration and reduce the noise; There is also a method to fundamentally solve the problem: remove the fan blade, use a thin wire to hang the fan blade through the small hole in the center of the fan blade, if one end drops, it means that this end is heavier, you can grind a few times on the grinding wheel, so that after several times, when the fan blade is hoisted with a thin wire, if the fan blade can be static in the horizontal position, it means that the transformation is successful. A few questions about oiling the fan:

1.Sewing machine oil or engine oil, the author recommends using four-stroke motorcycle oil, because sewing machine oil is very thin, fluidity and volatility are strong, it will not take long after oil injection, and the fan will be "old disease**", and the cushioning effect of sewing engine oil on vibration is also very small, for weakening noise, the effect is not big, and the use of engine oil just avoids the above two shortcomings. 2.

After the sealing problem of oil injection, a label paper is attached to the oil injection part of the fan, and after the label paper is removed and oiled, the label paper can generally not be used anymore, what to replace it? The author chose four or five layers of scotch tape. Find a roll of scotch tape, use a knife to cut horizontally, cut through about four or five layers, and then peel off these four or five layers of scotch tape together and you can use it.

Be careful not to use just one layer of tape, because a layer of tape is prone to vibration and noise when the fan is rotating, and it may be damaged and cause oil splashing. Another advantage of using scotch tape instead of label paper is whether the fan is short of oil, which can be seen at a glance and does not need to be disassembled.

My machine sounded, and my table vibrated especially in the light zone.

It's been a long time, that's it... No way.. It's a new one.

Get a new power source, or take the old one apart and get some oil. Be careful not to get electrocuted, it's best to unplug it and leave it for a day.

Remove it and lubricate it with oil, and you can look at the computer hardware maintenance book. See it and then dismantle it.

The same goes for my computer.

It is possible that the total power supply is turned off directly, and there is a great possibility of noise hardware problems, and the English letters appear because the system image is broken, so it is recommended to use software to detect it.

If it is a brand new computer, the process of operation is very quiet, but after a long time, you will find that the sound of the computer is getting louder and louder, and it has become a kind of noise, which is very annoying to listen to. Here's what I shared, let's take a look.

The main components of the computer host include: processor, memory, graphics card (ignore the collection of graphics cards), motherboard, hard disk, power supply and other computer hardware, and the accessories that are easy to produce noise mainly include: processor (mainly cooling fan), graphics card (mainly refers to independent graphics card), hard disk and finally memory.

In fact, the memory is relatively quiet, and even if it occurs, it is accompanied by the occurrence of computer failures, so strictly speaking, memory can also be eliminated.

1.Power supply fan noise cancellation

Power supply fan noise cancellation, which is divided into rotational noise and vibration noise. Rotational noise is generally caused by a lack of lubrication in the fan bearings. The solution is to apply a few drops of light lubricant (e.g. sewing machine oil) to the fan bearings.

Vibration noise is generally caused by unbalanced fan blades, loose blades on the shaft, and excessive bearing clearance. If the dirt accumulates on individual leaves, the dirt can be removed; If the fan blades are missing, asymmetrical, or the bearing clearance is too large, it is best to replace them with a new one'Power supply fan.

Fan noise cancellation

The bearings and blades of the CPU fan are easy to cause noise, and after long-term use, the bearing of the fan may have too much friction due to lack of oil, and it will also emit a large noise, so you can add some oil to the fan shaft. The specific operation is to carefully uncover the label on the fan hinge, add oil and then cover. Some people propose that vegetable oil can be used instead of lubricating oil when there is no engine oil, and it should be reminded that vegetable oil can also play a role in lubrication temporarily, but vegetable oil will become viscous after a period of use, which will affect the heat dissipation effect of the fan, so it is not recommended.

If the quality of the fan blade is not very good, after a period of rotation, the fan blade may be deformed due to heating, touch the inner wall, and make noise, in this case, you can take the blade to gently scrape a few times at the scratch, which is intended to increase the distance between the fan blade and the inner wall to avoid friction between the two.

3.Graphics card fan noise cancellation

First, by purchasing a silent graphics card fan and modifying the graphics card heatsink to achieve the purpose of graphics card noise reduction.

Although this method is completely straightforward, it costs extra to purchase a new graphics card cooler, and the replacement of the graphics card fan cooler will mean permanent idleness if it is no longer used, which is undoubtedly a waste of resources. Moreover, it is unknown whether the transformed graphics card cooling fan can meet the heat dissipation requirements of the graphics card chip itself, and whether the noise of the modified graphics card fan is really controlled.

Second, the noise of the graphics card is reduced through the functional software that comes with the graphics card.

Some major graphics card brands have developed some graphics card adjustment tools for gamers to use, and most of these tools have fan adjustment options. It can be used to adjust the wind speed. But not all graphics card manufacturers have the strength to develop software.

Brand graphics card risk control software is mostly applicable to some brands of graphics cards.

What to do if the computer is noisy – vibration noise

Some of the screws of the host are not tightened or used for a long time, and the screws are slowly loosened, and the noise is generated by their own vibration. Tighten the screws and you're good to go.

What to do if your computer is noisy – fan noise

The fan will make noise during operation, and the space should be rubbed during operation, and the fan with poor quality will have unstable speed and unstable rotation direction, so it is recommended to buy a fan with good quality to effectively reduce noise.

What to do if the computer is noisy - clean the dust inside the fuselage

After a period of use, due to the accumulation of too much dust inside the fuselage, which affects the heat dissipation, the fan has been at a high speed and the noise increases, as long as the internal dust is cleaned to achieve the purpose of noise reduction.

What to do if your computer is noisy – use power management wisely

With the help of third-party software, the CPU frequency, fan speed and hard disk of the notebook are manually configured, so as to achieve the purpose of mute, of course, this is obtained at the expense of notebook performance, which is more suitable for users who hang up**.

What to do if the computer is noisy - do not block the air inlet and outlet of the machine

Pay special attention not to block the heat vents, which will also cause a lot of noise on the computer.
