My computer s power supply fan has been turned on for a period of time and is noisy, what should I d

The oil should be wiped, but not the main thing, the main thing is to see if the cable in the case is too close to the fan, rearrange it, sometimes the line is too close, and the fan will have noise after the start-up time.

There is a piece of adhesive tape on the back of the fan, take it apart, add a little lubricating oil, and then glue the tape well.

Maybe you're using a low-quality mains fan. Wind wheels are not bearing.

Many netizens have the problem of how to deal with the loud computer fan in the process of using the computer, the loud computer fan will make people feel very uncomfortable using the computer, most of the computer is caused by the loud sound of the computer power supply fan or the loud CPU fan. What to do if the computer fan is loudWhat to do if the computer fan is loud? Through the dismantling of the computer power supply, the security engineer of Judun found that the loud sound of the computer power supply fan is generally due to the poor quality of the power supply fan, or the accumulation of a large amount of dust in the fan.

The poor quality of the power supply fan is usually that the fan sound of the computer is relatively normal at the beginning, but after a period of time, the fan sound will become louder, and the fans of many cheap computer power supplies are not of good quality, and it is recommended that netizens do not blindly pursue cost performance. In addition, the impact of dust on the power supply fan is also relatively large, we use the computer is generally put on the computer chassis on the ground, and the ground is the place with the most dust, a large amount of dust accumulated in the fan will inevitably affect its rotation sound, so that the computer power supply fan is loud. In fact, the reason why the CPU fan is loud asked by many netizens is basically the same as the computer power supply fan above.

What to do if the computer power supply fan is loudFirst of all, if it is an inferior computer power supply that you buy, Judun security engineers recommend that you replace it with a new one, because the computer power supply is not good, it will bring a lot of problems to the computer, the power supply is like a human heart, if it cannot provide strong power, the performance of the computer is bound to drop a lot. Change to a *** power supply, with a good power supply fan, so that there will be no problem of loud computer power supply fan. The second way is to clean up the dust of the computer power supply, after taking the power supply out of the chassis, you can use a soft brush to clean the fan, and you can also use a hair dryer to blow it from the inside to the outside, so that you can clean up part of the dust, of course, if you are troublesome, you can also find a maintenance person to help you clean it up.

Do the above, what to do if the computer fan is loud is not a problem, you don't have to worry about the loud power supply fan, at the same time, tell everyone that the CPU fan is loud is basically handled in this way, regularly clean up the dust of the chassis, and change it to a *** point if possible, these can reduce the sound of the computer power supply fan.

Reasons and solutions for the loud sound of the computer power fan:

One: The quality of the power supply fan is not good.

In some low-cost copycat power supplies, poor quality cooling fans are used a lot, which also shows that many power supplies are used soon after they find that the power cooling fans are obviously slow down or make noise, so the fans can be replaced.

Two: There is too much dust in the fan blades.

During the use of the power supply, because the power supply fan is rotated at a high speed for a long time, if the dust in the external environment is too large, a large amount of ash will accumulate on the blades of the power supply fan, and some thick dust will seriously burden the fan motor, resulting in some clicking noise from the fan that is difficult to run, so the computer should be placed in a relatively clean place as much as possible, and try to stay away from the road and dusty places.

Three: caused by long-term use.

If this is the reason, you can take the power supply out of the chassis, then open the power supply shell, clean the façade to a certain extent, and use a brush to clean the dusty power supply fan, which can generally solve the problem of high noise of the power supply fan to a certain extent.

If you have the conditions, change the power supply (nonsense).

If you don't want to change it, just change the power fan.

The power supply can be disassembled, but it must be dismantled when the power is off.

Just take it apart and replace it with a new fan.

It is generally 12cm, so you can measure it first.

Good luck.

Buying a silent power supply is the last resort, there is no need to invest in a hurry at the beginning, you can consider disassembling the machine, after disassembling the power supply, clean the fan and oil it, you can hold it for a while, generally speaking, if the power supply fan pays attention to maintenance, it will not be too noisy for four or five years.

Some desktop cases have adjustable speeds, ordinary cases can be equipped with sound-absorbing cotton, and laptops have wooden doors. (You can also wear active noise cancelling headphones to reduce the interference of external sounds, and the experience of watching movies and playing games will be upgraded.)

The current does not make a sound, it is caused by the poor quality of your fan! The solution is to replace!

Clean up the dust and add some oil to the fan, it is estimated that after a long time, the fan bearing is out of oil, and there is money to replace it directly.

1. Clean up the dust.

2. Replace the fan with a new one.

Don't know if your computer is a desktop or laptop? I'll tell you why for both desktop and laptop, I hope it helps!

There are generally 3 reasons why desktop computer fans are loud:

1. A lot of dust has accumulated on the sash, resulting in an uneven weight of the sash, and there is an off-axis phenomenon when it starts to rotate, and the sound will drop when it reaches a certain balance when it turns;

2. The fan bearing lacks lubricating oil, so it will be very loud all the time.

3. The power supply is not tightened or there are few screws, resulting in the vibration of the chassis caused by the rotation of the fan after the boot, if the chassis plate is thin, you can even feel the obvious vibration when you put your hand on the chassis.

The solution is to remove the power supply first, open the lid, clean up the dust on the fan page, suck it with a vacuum cleaner, and blow it with a hair dryer. Then take a rag dipped in some water to wipe the inside of the chassis, then dry, put some oil on the bearings, and finally install the chassis and tighten the screws.

If the laptop is loud, there may be the following situations:

1. If the use time is too long, the coil of the fan is aging and there is a lack of oil.

2. Due to improper use, the central shaft is bent due to impact or vibration.

3. The position of the fan is offset due to excessive dust accumulation or loose fixing screws.

4. Power supply problem.

If it is the first case, take the notebook apart by yourself, wipe the dust, put some oil, and then tighten the screws, lubricating oil and notebook cleaning agent, as well as disassembly tools can be bought on a treasure, very cheap. If it is the case, take it to the computer city and let the professional repairer repair it for you, and change the fan power supply.

Power supply fan noise is divided into rotational noise and vibration noise.

Rotational noise is generally caused by the lack of lubrication of the fan bearing, which can be applied to the fan bearing with a few drops of light lubricating oil (e.g. sewing machine oil).

Vibration noise is generally caused by unbalanced fan blades, loose blades on the shaft, and excessive bearing and clearance. If it is a dirt accumulation of individual leaves, it is enough to remove the dirt; If the fan blades are missing, asymmetrical, or the bearing clearance is too large, it is best to replace the power supply fan with a new one.

The optical drive is basically useless, just unplug the optical drive and not use it.

In addition, it is generally noisy, has little to do with optical drives, and is related to redundant CPU fans or graphics card fans.

Long-term wear and tear, or too much dust, can easily lead to a large increase in noise.

There are generally three reasons why fans are loud:

The first reason is that a lot of dust has accumulated on the sash, resulting in an uneven weight of the sash, there is an off-axis phenomenon when it starts to rotate, and the sound will come down when it reaches a certain balance when it turns around, and there is often a loud sound when it is just turned on, and the sound will be small after a while;

The second reason is that the fan bearings are lacking in lubricating oil.

The third reason is that the power supply is not tightened or there are few nails, which causes the case to resonate due to the rotation of the fan after turning on, and if the case sheet metal is thin, you can even feel obvious vibration when you put your hand on the case.

The solution is to remove the power supply first, open the cover, clean up the dust on the sash page, and then add some lubricating oil to the shaft. After cleaning up, put the power supply back into the chassis, be sure to tighten the four screws, and the screws on the back cover of the chassis should also be fully screwed.

In fact, in most cases, it is not a problem of non-lubrication, but the result of the fan head not being stable on the fan shaft and always moving up and down, so it is best to change a fan.

Buy a large fan and the original size of the same, and then replace it, the power fan generally does not have a plug, you can only cut the original old fan and dock the new one according to the color of the wire.

Due to the lack of lubricating oil in the bearings of the power supply fan.

If you have strong hands-on ability, you can take out the cooling fan, clean up the dust first, find the lubricating oil (sewing machine oil) to drip into the fan bearing (that is, the gap of the fan), don't order more, and then turn it a few times with your hand, and wait for a while to feel the lubrication and then install the power supply.
