After a while after turning on the machine, in addition to the sound of cutting wind, there was also

Intel boxed CPU fans are inherently noisy, and some motherboards automatically adjust the CPU fan speed according to the CPU speed, and the noise of the CPU fan is different in winter and summer, for the following reasons.

1. In summer, the CPU generates a lot of heat, and the fan speed is automatically adjusted (when the CPU workload is large, the power is relatively large, and the heat is also large), Intel is relatively louder than AMD.

2. Open the chassis, remove the CPU fan, Intel original CPU fan can disassemble the heat sink and fan separately, specifically clean the heat sink with detergent and water, it is best to use a brush with hard hair when washing, so that you can clean the heat sink more thoroughly, you can use alcohol or gasoline to make it clear, if you wash it with gasoline, it is best to wash it with detergent to get rid of the gasoline smell, pay attention to cool dry after washing, and then install it after the relative agitation is smaller. If it is not a good lubricating oil, it is better not to drip on the fan, and poor lubricating oil is easy to accelerate the aging of the CPU fan rotation (you don't look at the lubrication effect is very good when you first apply it, but it will not work after a few days).

3. Don't forget to prepare some silicone before dismantling, pay attention not to more or less when applying CPU silicone, find your own feeling, it will harden after a long time, but it will not play a better role in conducting heat, and when washing the heat sink, be careful not to use too much force or never use metal things to wash the copper of the CPU fan base.

If the computer doesn't crash, it's best not to disassemble it, and if you really can't stand it, spend a few hundred oceans to change a high-end CPU fan.

Do you just use a brush to brush the fan... This one you just don't spoil the rest of the warranty.

And if you want to be sure, you can ask the repair shop.

Let's see if there is a disc in the optical drive.

The causes and solutions of high noise when the computer is turned on are as follows:

1. The fan lubricating oil freezes in winter, and the temperature will rise normally if you have to turn on the machine for a while.

2. When the computer is turned on, the reason for the fan ring may be that the bearing of the fan is worn, try a good fan, it may be good, the power supply fan should be oiled once a few months, preferably the engine oil used in the car, and there is ash.

3. Tear the trademark on the fan, you will see a small eye, just use one or two drops of the oil to change the cone, don't pour too much, be careful to burn the fan.

4. The noise is mainly CPU fan, power supply fan, chassis fan, graphics card fan, after removing it, add oil one by one (sewing machine oil can be) There is a self-adhesive sticker on the back of the fan, and you can fill it with oil after uncovering, not too much.

5. If it doesn't ring after disassembling the case cover. It's machine vibes. Optionally, loosen the screws holding the case lid loose and it won't ring.

6. If it is sent from the direction of the power supply. You can clear the soil. If it still rings, it may be a failure in the electrical performance of the power supply. If you have a warranty, you can do a warranty, and if you don't have a warranty, you can go to repair.

7. If it is sent from the direction of the CPU. Try holding down the fan with your finger (be careful not to get hurt, and be sure to let go for about 5 seconds.) AMD's CPU is easy to burn).

If it doesn't ring, it's the reason for the CPU fan. You can try clearing the soil. Sometimes it's because of CMOS settings.

Just restore the factory settings.

Didn't they say that the dust had been cleared.

Since you said that the power supply fan is broken, you try to turn it on yourself to see if the fan is broken, or if it is oiled, the bearing is ashed, if it is dirty, you can wash it with gasoline, it is the kind of lighter oil, if the hardware is broken, then it can only be replaced for 10 yuan a can, if you can't buy it, you can repair the computer and dismantle the old place.

This is a sound caused by the difficulty of booting up, so it is recommended that you regularly clean the dust in the case or change the fan.

It may be a problem with the fan, is it time to remove the ash.

This is a minor issue.

You can listen carefully and judge which position it is.

The rattling is the hard disk, the hard disk is intermittent, and the hard disk light (the red light) will flash synchronously with the sound. The hard disk light flashes, there is data reading, which is normal, but with the data reading, the hard disk squeaks and rattles, which means that there is a problem with the hard disk.

There are four fans: power supply fan, processor fan, graphics card fan, and south bridge fan. If it's a fan, take it apart and listen closer, and you can find out which fan is ringing.

If the resonance of the case is loud, it will not sound when you press and hold the case by hand. The optical drive and hard disk are not fixed and do not emit sound, you can try them one by one.

I really can't hear it, so I take it apart. Use the method of elimination.

1. First disassemble the chassis, dial the hard disk cable, remove the optical drive, turn on the machine, there is a sound is the fan, if not, try again.

2. Connect the hard disk cable, turn on the computer, there is a sound is the hard disk, if not, continue to try.

3. Connect the optical drive, turn it on, there is a sound is the optical drive, carefully fix the optical drive, and try again if not.

3. Put the chassis on, turn it on, there is a sound that the chassis is not fixed, and you should try it out, there is no place to make a sound, and then you can only see if the computer desk is not strong.

It's impossible to try again, I guarantee with my years of computer repair experience, I will definitely find it, if you are lucky, according to the voice and location I said, you can find it without disassembling the case.

Problem analysis: This noise is generally caused by the internal fans of the host, including the power supply, CPU, and graphics card fans. Due to the long use time or cold weather, the effectiveness of the lubricant inside the fan decreases, and the dust accumulates, the running speed of the fan decreases, and the friction increases.

If the noise resonates with the chassis frame, not only the loud noise but the entire chassis will vibrate. In addition, it is not excluded that the internal screws of the chassis may loosen and cause noise, and the mechanical hard disk will also produce noise when reading and writing.

Treatment suggestion: After a period of use, the lubricant inside the fan gradually recovers due to friction and heat, and the sound is reduced accordingly. If you don't see improvement, here's what you can do:

1. Use leather tigers, soft brushes, etc. to dust and lubricate the fan inside the case, or directly replace the new fan.

2. Tighten the screws on each part of the chassis.

3. If the mechanical hard disk is noisy, it can be replaced with a new hard disk or solid state drive.

The fan is worn out, replace it with a new CPU fan and mute the fan.

The noise of the CPU fan can be solved as follows: Many friends' computers will be buzzing in the box when they are just turned on after a period of time, and they will return to calm after a few minutes. People generally don't pay much attention to this problem, and some people will pat the case a few times to reduce the noise.

In fact, this is a manifestation of the lack of fuel in the CPU fan or power supply fan, which is not conducive to the safe operation of the computer. Let's talk about the cause of noise first: When the fan has been running for a long time (generally after two or three years, this phenomenon begins to appear, and a better fan can rotate for a longer time), the lubricating oil in the fan oil bladder is exhausted, and dry friction occurs in the fan bearing, resulting in noise.

After the machine is turned on, the fan rotor is not in its equilibrium position, and after a period of rotation, the dust in the bearing gap will be worn off, or grinded finely, so the noise will become smaller for a period of time, and this is also the reason for the noise to become smaller, which is to return the bearing to the equilibrium position with the help of external force. But this is very unsafe, because the hard disk is spinning at high speed when the computer is running, and at this time, the hard disk will vibrate, which may cause the hard disk to produce physical bad sectors, so be careful! At this time, if the lubricating oil is not added in time, the fan will be damaged, the bearing gap will be worn more and more, and the noise will become louder and louder, until the fan is scrapped; In severe cases, the CPU has poor heat dissipation, and it often crashes or restarts for no reason, and in more serious cases, the CPU may be burned.

There is a lot of dust on the host, and there is a computer that has been bought for a long time, and the host hardware (fan...).Damaged.

There is a sound after the motor box is flushed. If there is a device that moves mechanically, there must be noise.

If the noise is very loud, oil the part with mechanical movement (usually the CPU, graphics card, power supply fan), or replace the fan, the shaft of the fan will be covered with dust after a period of use, including the imbalance of the blades, the wear of the bearing, will produce a lot of noise.

It is also purely judged that some of the noise is caused by the resonance of the case or the resonance frequency of the case is very close to the resonance frequency of the case or the position of the case (such as the desktop) and causes greater noise.

The easiest way is to put the case away from people or in a cabinet, so that the sound will not be heard :)

If there is noise, it is generally the sound of a fan, please check how many speakers there are in your case, generally there are at least two, one is the fan of the CPU, and the other is the fan of the power supply.

The noisy fan is often caused by two aspects, one is that there is too much dust, causing clogging, and the fan is desperately spinning, but to reach the cooling destination, it cannot get enough wind due to the obstruction, so the temperature remains high. As a result, the afterburner of the fan rotates but the effect is not good.

If it is not the problem of the fan, it can only mean that the silicone between the fan and the connecting object is gone, and the silicone needs to be replaced. For example, the silicone of the fan attached to the CPU fails.

Clause.

1. When the computer is turned on, the CPU occupancy rate is high, so the fan speed will be fast, so the sound is relatively normal.

Second, the CPU or power supply fan shaft is a little sent, and when it rotates at high speed, it is not stable, the friction is large, and the sound is loud; (Change the fan or add electric lubricating oil).

Clause. 3. There is too much dust in the fan blades and shaft, (it can be solved after dust removal).

Either the power supply fan is too dusty.

Or maybe the CPU fan is not stable.

Or maybe the graphics card fan is about to run out of oil.

Because of this, my computer has also appeared.

But unlike you, I don't have to shoot the case.

It's just a flick of the fan.
