Solve from these aspects:

1

Dismantle the chassis and clean all dust (especially in the northern area), preferably using a waste brush with the help of a vacuum cleaner.

Clean enough to be cleaned.

2

, uninstall

cpu

Fan channel fixing screw, open it carefully.

Radiator, you will find.

cpu

In the gap with the radiator

The siloxane ester has been dried (with

cpu

High power has a lot to do with it), clean the dry silicone ester with a slightly wet cleaning pad,

Dry.

three

If conditions permit, it can be supplemented with advanced silicone ester; If the conditions do not allow, it can be supplemented by the following methods: ordinary silicone ester that needs to be purchased or white.

A little bit is extruded onto the glass plate,

Grinding and stirring the glass with a carbon pen,

Until the white silicone ester turns light gray and becomes

Slightly thicker, clean with a blade.

cpu

Apply a thin layer of mounting fins on it, and remember not to move the fins back and forth.

Sheet, so that the radiator and

cpu

Good contact. There is no difference between the silicone ester made by this method and the special silicone ester made by Intel.

Large, good thermal conductivity, not easy to dry.

four

Insert the large fan carefully, and carefully remove the circular sticker with the trademark at the center of the fan, so that you can see the central shaft.

Exposed, carefully apply vaseline (very cheap, sold in pharmacies) and seal it carefully.

Circular adhesive with trademark

Do it. -Principle: Vaseline should be applied to hands to prevent dry and chapped skin in winter. It has one feature: it is used as a fan.

Heat is generated when working,

Vaseline gradually melts and penetrates into fan bearing lubrication,

Turn off the fan, stop working,

rule

When the temperature drops, vaseline will solidify and stand by. This method is better than adding any lubricating oil.

five

Mount the chassis, and put a slightly thicker rubber cover on the front and back of the chassis to play a role in shock absorption.

six

Try it on. It's not obvious at first. About a week or so, you will find your computer fan and chassis.

The noise is getting smaller and smaller, which is basically the same as when I bought it.

2)

Expert analysis: the longer the computer is used, plus the host has been moved by some people, or the internal hard disk, fan and other departments.

With the continuous operation and rotation of the parts, sometimes there will be slight loosening of the screws, which will lead to increased vibration and noise. In addition, if

If it is used for too long, the rotating shaft of the fan will become drier and the rotating tone will be improved due to lack of lubrication.

hurried

Be quick:

For this little problem,

If a computer user who has not passed the warranty period does not want to break the warranty seal by opening the chassis,

Just send the main engine to the maintenance station and let the manufacturer handle it for you.

If you are a computer user or the host has passed the warranty period.

Period,

Then you have to open the chassis,

Tighten all visible screws,

Drop one or two drops of lubricating oil on the fan shaft,

by the way

Dust the chassis, and the noise of your mainframe will be reduced a lot.

3)

The main sources of computer noise are as follows.

：

hard disc

Power supply fan

cpu

fan

Xiankafeng mountain

Main board equipment

* * * Vibration

Sound comes from vibration, and only vibration can produce sound. There is no doubt that the huge noise of the host when the computer starts is caused by

It is caused by the strong vibration of some components inside the main engine. An important factor is the power supply fan and

cpu

When the fan starts the computer,

Produced by rotation.

There are many reasons for the harsh boot noise.

But the main reasons are nothing more than the following:

fan

* * * Vibration phenomenon is caused by

：

One,

Chassis structure,

The natural frequency of the system composed of power box installation structure is low.

(that is, the structural rigidity is poor)

When the fan is running, the rotating speed is gradually increased.

When the rotating speed is close to the natural frequency of the system, * * * vibration phenomenon begins to appear.

With the fan speed

The increase of degrees is closer to the natural frequency of the system,

The vibration intensified,

Shaking table when fan speed is the same as system natural frequency.

Now is the most intense.

As the fan speed continues to increase,

The rotating speed of the fan gradually deviates from the natural frequency of the system,

The vibration also gradually weakened and recovered.

Normal.

b，

fan blade

"

part of

"

High-quality fan, its blade center of gravity is on the shaft, it runs very smoothly and has little noise.

And inferior fans, there will be some deviation, the center of gravity of fan blades is not caused by the shaft.

"

part of

"

Such a fan rotates.

After getting up,

Equivalent to an oscillator.

(The oscillator adds an eccentric wheel to the motor shaft)

as time goes on

Longer,

The fan bearing gradually wears away,

Or the cooling fin of the fan is not firmly installed,

Loose, etc.

Will make the vibration aggravate the noise.

Get bigger. It may also be because of the poor quality and lubrication of the fan, which was very astringent at first, but the lubricating oil in it became soft when it was activated.

, the voice is very small.

.

c，

The chassis structure is not tight: the hard disk is not in close contact with the chassis bracket, or the chassis steel plate is too thin, which is easy to send out some.

Annoying noise. The noise from the power supply fan may be due to the poor cooperation between the chassis and the power supply.

.

The rotation of the power supply fan causes the chassis.

* * * Vibration

.

In addition, unstable installation of other hardware inside the chassis will also cause vibration.

Cold weather and low temperature:

Some fans

The surface is made of grease,

The temperature is low in winter,

The grease in the fan solidified,

When the fan is started, the temperature of the bearing part of the fan is low,

The viscosity of lubricating grease is high,

High rotation resistance,

Louder and louder,

After rotating for a period of time, the temperature of the bearing part of the fan rises,

lube oil

When it starts to work, the noise will return to normal after opening. This usually occurs in the first few minutes of startup.

In this way, there will be no noise in other seasons.

The fan bearing is short of oil: if the sound is always loud, it means that the fan needs it.

Let's go

There is a round sticker in the center of the bottom surface of the fan.

Turn on the fan and you can see the rotating shaft inside.

Dip it with a toothpick.

Just add some sewing machine oil (about the size of rice grains). Then apply adhesive. include

cpu

Fans, video card fans,

All power fans can refuel. If you don't know how to refuel, you can go to a computer repair shop and let professionals do it.

Hard disk noise:

The hard disk sound is mainly loud,

Hard disks with poor quality will be louder.

If it's hard,

Excessive disk fragmentation will also increase the workload of the hard disk and make the sound louder.

Another situation is that the hard disk has a bad track.

Will also guide

Make the hard disk louder. ordinary

integrated drive electronics

Hard disk will have certain working noise during normal operation. But these sounds are very small,

And it only happens when reading hard disk data.

Dust accumulation: chassis, power supply,

cpu

A large amount of dust accumulated on the radiator will also

Causing the fan sound to increase.

.

You can try to turn it on, slowly debug the power supply with a screwdriver, and put those screws on the chassis to see.

Did it work?

See if the chassis layout is deformed.

,

If there is a change

,

The noise source may be a pow supply,

cpu

wind

fan

.

The above reasons are all attributed to the fan, so we can solve them in the following ways:

Chassis hardware

Dust removal, fan refueling, and fixing the internal hardware of the chassis.

But also pay attention to the following points:

1

. Pay attention to the power supply,

cpu

The lubrication of fans, some fans are not good in quality and lubrication, and they are very astringent at first, so they have to wait for the rotation.

When you are alive, the lubricating oil inside becomes soft and the sound is small;

2

Do not move the chassis while running the computer.

.

Chassis cover should be installed in place. If there are cracks, when the computer is running,

The chassis will vibrate and make a lot of noise. If the chassis is deformed, you can pad something soft under the chassis, such as sponge and foam.

Seismic materials.

three

Don't disassemble the fan at will, it may be installed incorrectly, which will affect the rotation and make a lot of noise. You can find a major if you don't understand.

Personnel help to deal with it.

four

Dust your mainframe regularly, usually once a year, and the frequency of dust removal can be appropriately increased in dusty places. oneself

If the vacuum cleaner lacks equipment and is afraid of trouble, it is recommended to go to a computer repair shop to clean it.

five

Cold weather and low temperature are a cause that cannot be ignored. If this is the reason, it can be said that the machine is completely normal, but it is not.

Is there any good solution? If not, you can increase the boot time in winter or leave it on directly.

fan blade

"

part of

"

The solution to the problem is to install the fan firmly as far as possible so as not to vibrate; Another way is to give

Oil is injected at the fan bearing,

Plays the role of buffering vibration,

Thereby reducing noise.

The first two methods did not solve the substantive problems;

most

The latter method:

Remove the fan blades,

Lift the fan blade with a thin thread through the small hole in the center of the fan blade. If one end falls,

Explain this.

The ending is heavy,

Can be ground on the grinding wheel for many times,

After so many times,

When the fan blades are hoisted by thin wires,

If the fan blades are stationary in the horizontal position

Stop,

Explain that the transformation has succeeded.

The last one is more complicated,

If you use the computer for a long time, you really can't solve the problem by yourself.

Structure of direct displacement fan.

Computer noise mainly comes from fans. Many materials introduce oiling the fan to reduce noise.

The method of sound,

But the noise of the fan is not necessarily due to the lack of oil in the bearing.

Therefore, we should consider all kinds of situations comprehensively.

Discover from ...

Find out the real reason for the loud noise when the computer is turned on, and prescribe the right medicine to get rid of the disease.

Usually in the brain

three

A place

There is a fan, one is a power supply, and there is a fan inside, which can be used to disassemble the processing butter; The other two are

cpu

Fan or

Even the video card fan can be temporarily solved by adding industrial butter to the shaft.

Of course, this method refers to computers.

Long-term use,

The method used when the dust accumulation is more and the rotating shaft rotates unevenly.

A new computer,

Or for domestic use,

It's only been a month, which means the quality of the fan is not good. If the economy permits, it's best to change it to a new one. To be quiet, this money

It is still worth spending.
