Computer noise, the reason why computers are noisy

Method: Uncover the paper at one end of the hinge, you will see the hinge, add an appropriate amount of sewing machine oil (even cooking oil) to lubricate, which will greatly reduce the noise of the fan.

The sound of the hard disk is loud, the sound of the hard disk is mainly a gurgling sound, the hard disk of bad quality will be louder, and if the hard disk fragments are too much, the workload of the hard disk will be increased and the sound will be louder, and there is a situation that the hard disk has a bad sector, which will also lead to the sound of the hard disk to increase, just scan it, and defragmentation should be done, by the way, BT and other **tool** files will produce a large number of disk fragments, and the solution is to dump the movie that has been ** every time ** is completed, Save to another partition.

The resonance of the computer noise reduction strategy.

The noise you're talking about is mainly from the CPU fan.

Fans all need lubricants, but all lubricants have a certain operating temperature range. When the weather is too cold, not in the operating temperature range, it will not play the role of lubrication. The heat emitted by the CPU when working increases the temperature of the fan's lubricating oil, and when the working temperature of the lubricating oil is reached, the sound will be quieter.

In addition, CPU fans are easy to accumulate dust, and they need to be cleaned regularly, or they will cause a lot of noise.

Take the case apart, then turn it on, listen to which fan is louder, and replace the loud fan.

The fan will automatically adjust the speed with the temperature, but this has little to do with the noise, and even if the noise is smaller, it will not be much smaller.

The boot sound becomes louder and quieter after a while, and that is the graphics card fan. Changing handles, it doesn't cost much.

The balls of the fan bearing are cracked or damaged, and it is recommended to replace the fan with a new one immediately. It has nothing to do with the temperature of the host itself.

You have to determine which fan it is, the graphics card? cpu?Power supply? And then change again.

The whole CPU cooling software or change the fan.

There are many reasons why a computer is noisy, it can be a problem with the hardware device, or it can be a problem with the software. Here are the possible reasons why your computer is noisy:

1.Fan issues.

Fans are part of the cooling system and are susceptible to dust and debris. If your computer's fan is dusty or damaged, it will make noise. At this point, the fan can be cleaned with a cleaning spray.

2.Hard drive issues.

The hard disk will make noise when reading data, and if there is a problem with the hard disk, such as the head of the magnetic head, which is a barrier or the sound is irregular, it will emit an abnormal sound.

3.Power issues.

If there is a problem with the power supply's fan, it will cause noise, and the broken fan needs to be replaced with a new one.

4.Graphics card issues.

The noise generated by the graphics card may be caused by the fan or voltage converter, and you should use a new fan or choose a better heatsink to solve the problem.

Issue. The noise emitted by the CPU usually comes from the fan, and this is because the temperature is too high and the fan has to run to lower the temperature. Installing a better heatsink or a better fan on the CPU can alleviate noise issues.

6.Silicone mat problem.

Some computer silicone feet may become brittle after a period of use, and Zen Sakura loses its elasticity, causing noise between the case and the computer desk underneath. To avoid this problem, it is best to use high-quality silicone pads.

In conclusion, there are many reasons why a computer is noisy, and the above are just a few of the possible causes. If your computer noise problem is serious, it's best to quickly find the specific cause and fix it in time.

The main engine is noisy because your power supply fan or CPU fan has been used for too long and the inside is dry, so put some lubricating oil on it.

2: This is mainly a problem with the power fan, you can try to change to a better power supply, such as the Patriot Calm King.

3: Fans, including fans for power supply CPU graphics cards. You can clean the fan yourself or change it.

4: A start-up noise, most of them are the problem of power supply fans and CPU fans, now many fans have a very short life, if you often use the computer, it is not recommended to refuel, it is best to replace a *** fan, in order to prolong the use of time, after all, this is an important part of the computer, the instability of the computer, most of the crashes are related to it, in addition, the computer is regularly cleaned and maintained, but do not use as little oily substances and chemicals as possible in the computer, because the oily substances condense and melt, and the computer is damaged for a long time. Chemicals can easily damage the computer's precision.

Recommended answer The computer is noisy, if it is determined that it is fan noise, there will generally be three places, 1. Power supply fan. 2. CPU fan. 3. Graphics card fan (don't ignore this, it is estimated that most of the noise of your computer comes from this) You can try it yourself:

Open the case, lay it flat, turn it on, gently press and hold the CPU fan with your hand, listen to the noise, if it disappears, it means it is CPU fan noise, then press the graphics card fan, if it disappears, it means that it is the graphics card fan noise, if neither of these two are it, it is the power supply fan noise. Note that you can't hold down the fan for too long, as it will burn the CPU or graphics card if it's too long. Whichever is it, change it.

Judging from the above, it is not the problem of the fan, that is the problem of the chassis, as mentioned above, when the chassis is placed flat, if the noise is significantly reduced, most of it is the chassis noise, you need to check the motherboard, graphics card, optical drive, hard disk, and power supply screws in the chassis, whether there is any looseness, and tighten it. If it still doesn't work, then find some screw gaskets, preferably spring gaskets or rubber pads, for the optical drive, power supply, motherboard screw pads, it will improve a lot.

Computer noise is normally a fan problem, and it is generally the cause of the fan accumulating too much dust. There are two important fans in the computer, one is the CPU fan, and the other is the graphics card fan.

If you know the hardware, just open the case, remove the fan, and remove the dust inside. If you don't have too much confidence in computer hardware, you can find a friend who knows some hardware knowledge to help you.

Hello. It should be that your desktop fan is contaminated with too much dust, or because there is too much dust in your case, resulting in the CPU and graphics card temperature being too high, and the noise caused by the increase in fan speed, you can disassemble the computer to clean up the dust, and then add some oil to the fan blades.

Hope it helps.

When the weather is cold, the oil in it solidifies, so the sound is loud. First of all, you have to know that there is sound there, just change it, the fan is not valuable, the power supply, the CPU. Graphics. chassis, excluded one by one.

Generally, the fan is unstable, the fan motor is short of oil, or the motherboard fixing screws are loose, and the host or computer is not placed stably.

It should be that the fan is about to break, either the power supply fan or the radiator.

Generally speaking, it should be a hardware problem, if there is a lot of dust, you can get rid of the dust, play large games, open too much software, and the computer will be noisy to run.

Generally, it is a fan problem, if you want to repair it yourself, get the fan down and add a little lubricating oil.

If it doesn't work, or it doesn't work, it's best to just replace one.

It's due to the cold weather! The fan lube is solidified! That's why it makes a lot of noise!

Wait until half a minute later, the temperature inside the main chassis will rise! When the oil melts, there is no noise! You can add some lube!

Or get a new fan! Otherwise, just use it! It doesn't matter!

Normal! It won't have much of an impact.

In order to eliminate the vibration noise of the case, we can pay attention to the hardness of the case and the connection between the case and the cabinet when purchasing a computer. Chassis with materials that are too thin and use too "economically" are not strong. Gently squeeze or twist the box by hand to check whether its hardness is acceptable.

A case with a screw-on lid and body is more stable, while a screw-free case is prone to vibration, so it's best to consider it when buying. In addition, some appropriate shock-absorbing measures can be taken during installation and use, such as pasting a 3 4 mm thick plastic foam strip on the part of the box lid that is in direct contact with the box body, and then tightening the box cover.

The bearings and blades of the CPU fan are the most likely places to cause noise, and after long-term use, the bearings of the fan may have too much friction due to lack of oil, resulting in large noise, so you can add some sewing oil to the fan shaft. The specific operation is to carefully uncover the label on the fan shaft, add oil and then cover it. If the quality of the fan blades is not very good, after a period of rotation, the fan blades may be deformed due to heating, touch the inner wall, and make noise.

The solution is to take the blade and gently scrape the scratch a few times to increase the distance between the fan blade and the inner wall to avoid friction between the two.

Power supply fan noise is generally 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 sewing oil to the fan bearing.

Vibration noise is generally caused by unbalanced fan blades, loose blades on the shaft, and excessive bearing clearance. If it is the accumulation of dirt on individual leaves, it can be removed in time; 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 noise of the hard disk may come from its own vibration, and at this time, it is not just as simple as making annoying noise, but also involves the safety of the hard disk. Because the vibration caused by improper installation may damage the hard drive, the drive installed horizontally must be parallel to the chassis, and the vertically mounted hard disk must be perpendicular to the bottom surface of the chassis and not skewed. The most important thing is that the hard drive must be in a stable state (it is recommended to use more than three screws to fix the hard drive), but at the same time, it is important to make sure that the set screws of the hard drive are not too long or too tight to prevent damage to the circuit board and platter.

Hope it can help you, thank you.

: Power Fan Noise, CPU Fan Noise, Optical Drive Noise, Hard Drive Noise, and Case Noise.

1. Power supply fan noise: Power supply fan noise is divided into rotation noise and vibration noise. The rotational noise is generally due to the lack of moisture in the fan bearings.

If it is slippery, you can put a few drops of light lubricant (e.g. sewing machine oil) on the fan bearing. 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.

2. CPU fan noise: CPU fans and fan blades are easy to cause noise, and the bearings of the fan may make a lot of noise due to too much friction due to lack of oil after long-term use. You can tear off the label on the fan hinge, add some oil and then cover.

It is not advisable to replace engine oil with vegetable oil here, because over time, vegetable oil will become viscous and affect the heat dissipation of the fan.

3. Optical drive noise: As the name suggests, optical drive noise is the noise generated by optical drive. You can use virtual optical drive software to make some commonly used optical discs into images and store them on the hard disk.

You can also use the optical drive deceleration software to slow down the optical drive, and the current high-speed optical drive is completely crazy for the sake of market competition, and you can use nero

drivespeed.

4. Hard disk noise: Hard disk noise comes from the vibration of the hard disk. Horizontally mounted drives should be parallel to the chassis, while vertically mounted drives should be perpendicular to the underside of the chassis and should never be skewed. The most important thing is that the hard drive must be tightened and not overtightened.

5. Chassis noise: If the chassis makes noise, a styrofoam strip should be pasted in the appropriate place, and then the chassis cover should be tightly covered.

The reasons may be:

One is the sound of the CPU fan, if that's the case, you should clean it up and put some oil on it.

The second is the sound made by the power fan. You can clean it up first, and change the power supply if it really doesn't work.

The third is the sound that occurs when the hard disk is read, which may be the noise that occurs when the hard disk is aging or bad sectors, and you can make a judgment according to your situation! Hope it helps!

Look at the specific noise in order to solve it in a targeted manner.

Generally, it is nothing more than the noise of CPU fans, graphics card fans, or case fans.

The case fan is best solved, and it is OK to change the silent fan. Now that the temperature has come down, if you don't want to buy a fan, it's not a big problem to pull it out.

If you have a CPU fan, you can change it with the heatsink, depending on your CPU model, dozens to 100 is already good.

The graphics card fan is more annoying, and there are also those who buy a graphics card radiator, but I don't know if there is a problem with the warranty after dismantling it.

Another possibility is that the chassis is too thin, causing the fan to rotate and cause the chassis to resonate. In this case, in addition to changing the fan to see the effect, if it doesn't work, it's best to change the chassis. A case that is too thin is not strong enough, and it is also a burden on the motherboard, and it will cause problems after long-term use.

A noisy computer can be caused by a variety of reasons, and here are some common ways to fix it:

1.Clean your computer: Dust or clogged fans can also cause a lot of noise, so clean the inside of your computer and the fan regularly.

2.Replace the fan: If the main source of computer noise is the fan, you can try to replace the fan and choose a low-noise fan.

3.Adjust power settings: You can optimize your computer's power consumption by adjusting the power settings to reduce your computer's operating noise.

4.Sound insulation: Installing a soundproof panel or using a soundproof pad on the outside of the computer host can reduce the noise transmission of the computer.

5.Replace hard drives: Compared with mechanical hard drives, SSDs are usually less noisy and can be replaced with SSDs on the premise of ensuring storage capacity.

6.Bring in an external sound source: You can use a device such as a headset to block out the noise from your computer.

The above are some common solutions, and you need to choose a suitable method to solve them according to the specific situation.
