The sound of the computer host will be louder and quieter

That's the sound produced by the CPU fan working, as the CPU processing tasks gradually increase, the fan on the CPU will speed up, and there will be a burst of noise inside the inverted case, which is normal! There is also an increase in dust on the CPU fan, generally these two possibilities! It also means that your computer needs to be dusted up, or the configuration needs to be improved!

The CPU fan sound is normal, if the sound gets louder frequently, your system may have too much garbage, clean up the disk, or reinstall the system, of course, dust removal in the host is also necessary.

There are no more than two places of sound origination:

One is the fan (including the fan of the graphics card, CPU and power supply) and the other is the hard disk and optical drive.

You didn't explain exactly what kind of sound it was, so I can't judge.

You open the case and listen carefully, where exactly is the sound.

1.Fan sound problem solved:

Add lubricating oil, tear the label of the fan, there is a small hole in the back, and add some sewing oil to it. Even peanut oil will do.

Check whether the parts of the device that fix each fan are loose.

2.The sound of the hard disk: The hard disk is aging and can only be replaced. This is irreparable.

3.The sound of the optical drive: 1) Take the optical disc, the optical disc should not be placed in the optical drive for a long time.

2) The optical drive is aging and the optical drive is replaced. This is irreparable.

I guess it's a fan problem!

There are CPU fans, graphics card fans, power supply fans, motherboard fans in the case, you listen carefully, if you hear which fan is loud, you remove it, put some lubricating oil in the middle shaft, your sewing machine oil can also be installed, try it again, if it is still loud, go buy another one, it shouldn't be much money.

Picked up, from:

When the computer is running, the main unit is noisy, which is usually caused by the fan.

Workaround:1Due to the lack of oil and dryness, the fan starts with a large torque, and the noise is large, and when the speed is normal, the torque is smaller, and the noise is reduced. If the noise is too loud, the CPU fan, graphics card fan, or power supply fan in your computer needs to be refueled.

2.In addition, check whether the chassis is vibrating, do not move the main unit slightly, or press the handle on the cover plate of the chassis to try it out. The method of checking by hand is that if the sound of pressing on the hand is low, it is the case vibration, check whether the cover plate screws are in order, or the quality of the case is too poor.

If there are no major changes, it should be a fan problem.

Power supply fan and CPU fan noise are the main sources of noise. The problem of power supply fan noise is relatively easy to solve, just buy a silent power supply.

The noise reduction method of the power supply fan is generally to reduce the fan speed, and if the CPU fan reduces the speed, it will inevitably affect the heat dissipation of the CPU, so the CPU noise reduction method mainly lies in the lubrication of the bearing and the structural design of the fan blade.

Due to the high speed of the CPU fan, it is a bit difficult for the CPU fan noise level to reach the level of a silent power supply, but we still try to choose a fan with a silent function. Of course, it's also a good idea to add some lubricant to the fan bearings yourself.

The noise generated by the graphics card fan and the case fan is relatively small, but too many case fans installed in the case can also increase the noise of the computer. Installing as few fans as possible is an effective way to reduce noise, but for those computers that must have multiple case fans, you can choose some case fans with large diameters and low speeds.

There are several reasons why the computer is noisy when it is running:

1.The CPU fan is abnormal. The CPU is the central processor of the computer, which generates a lot of heat when it runs and needs a fan to dissipate heat.

If the CPU fan is running abnormally, such as spinning too fast or there is friction noise, it will cause a lot of noise. The CPU fan needs to be checked, cleaned or replaced.

2.The hard drive is damaged. There is a slight noise during the reading and writing process of the hard drive, and if the hard drive is damaged, this noise will be increased, such as a knock or bump. You need to check the status of the hard drive, back up the data and replace the hard drive.

3.The host fan is stalled. In addition to the CPU, there are other chips in the host that also need fans to cool the heat, and if the host fan is blocked or running abnormally, it will also increase the noise. You need to clean up the dust inside the main unit, check the fan, and replace the abnormal fan.

4.The power strip is overheating. The power strip converts alternating current into the required operating voltage for each component, generating a certain amount of heat during operation.

If the power strip does not dissipate enough heat and overheats, its fan will also speed up and produce noise. The power strip and fan need to be inspected and repaired or replaced as necessary.

5.Other parts are abnormal. Other components such as optical drives and graphics cards will also have a certain amount of noise when they are running. If these parts fail or are damaged, the noise of the parts themselves or the noise of their fans will increase. It is necessary to check the operation of each relevant component.

First of all, check the fan and heat dissipation in the main unit, and clean up the dust to ensure the cooling effect of each component. Then check the CPU, hard disk, motherboard and other key components to monitor their operating temperature and noise. Backups and replacements are carried out when necessary.

If the above measures still do not solve the problem, it is recommended to send the main unit to a technician for comprehensive testing and overhaul to find out the noise source and repair it, so as not to affect the performance of the main engine and damage other parts.

When the computer is running, the reason why the sound is particularly loud may be:

Fan noise: The fan inside the console may be noisy due to dust accumulation or damage.

Hard drive noise: Hard drive work can also produce noise.

Heat dissipation issues: If the temperature of the host unit is too high, the fan may speed up and produce loud noise.

Power** Noise: Inferior or aging power ** may produce loud noise.

Hardware failure: Some hardware components can be damaged or malfunction, resulting in increased noise.

The host computer is particularly loud when the computer is running, which can be caused by several reasons:

1.Poor fan heat dissipation: After the computer is used for a long time, the hardware may produce high temperatures, and in order to ensure the stability of the hardware, the computer uses a lot of fans to dissipate heat.

If the fan is faulty or has too much dust, it will cause the fan to slow down, the heat dissipation will be insufficient, and the main unit will make a loud noise.

2.Noise during hard drive read/write: The hard drive does not have a normal read and write process and may make loud sounds. In this case, you need to check for hard disk failures or clean up junk files.

3.High CPU usage: If some programs or tasks in the system are too heavy, resulting in high CPU usage, the host will make a loud noise because the processing power cannot keep up.

4.Power overload: If your power supply is too old or overloaded, then it will provide more power, which will cause the console to make a loud noise.

In these cases, you can first try to clean the fan and cooling devices, check the health of the hard drive, improve the processing efficiency of the CPU, and upgrade the power supply. If the problem cannot be solved, you can seek professional help.

Noise from the host computer (or computer case) is usually caused by several reasons:

Dust or impurities inside: If your computer hasn't been cleaned for a long time, the dust and impurities that have accumulated inside can cause parts like fans, radiators, and more to become noisy. Please use a compressed air tank or professional cleaning tool to clean the inside.

Outdated or failed fans: If your computer has been in use for a long time, the fans may be aging or failing. Please replace the fan with a new one and make sure it is compatible with your computer.

Hard drive problems: A faulty hard drive or an abnormal turning sound when reading data can also cause the computer to be noisy. It is advisable to back up your data and check if your hard drive is failing.

Particularly loud when a computer is running is usually caused by several reasons:

1.Fan failure: There are multiple fans in your computer's main unit to dissipate heat and keep the internal temperature stable. If one or more of these fans fails, it can cause the main unit to overheat, causing the other fans to spin faster and make louder noise.

2.Dust accumulation: Prolonged use of the computer will cause dust to accumulate inside, affecting the normal operation of the fan, resulting in noise.

3.Hard drive issues: Hard drives may make noise when reading data, and if the hard drive is damaged or aged, it can also cause loud noise.

4.Power issues: Power failures or aging can also cause increased host noise.

To solve the above problems, you can take the following measures to solve them:

1.Clean the inside of your computer, especially the fan and radiator.

2.Check whether the fan is working properly, and replace it in time if there is a problem.

3.Place the computer in a well-ventilated place to avoid running under high load for long periods of time.

4.If necessary, replace damaged or aging hardware devices.

5.If the above measures do not work, it is recommended to seek the help of a professional for repairs.

The reason why the computer host is particularly loud when it is running:

The normal phenomenon of fan operation: due to the use of the fan for too long, the interior is dry, etc., there will naturally be humming noise, and the dust is completely cleaned.

Take win7 as an example to introduce the setting method:

2. Click the speaker and click the configuration;

3. Select the "Level" tab and click "Flat Sail Rough Balance";

4. Drag the two sedan diversion sliders to the right and click OK to close the dialog box.

Summary. It's because at first your ** is loud, and then you press the sign, which is equivalent to turning down the volume, so the volume is low.

Why is the computer loud at the beginning, and the sound is low when you press it.

Hello dear, the computer sound is very loud at the beginning, and the sound is low when you press it, and the reasons are as follows

This is due to the fact that when the weather temperature is not high, the grease in the CPU fan is somewhat solidified, the temperature of the fan bearing part is low when it is just turned on, the viscosity of the grease is large, the rotational resistance is large, and the sound is loud, and the temperature of the fan bearing part rises after turning it for a while, and the lubricating oil begins to work, and the noise situation at the time of booting will return to a normal state, so the sound is louder when it is just turned on, and the sound is smaller after a while.

It's not the sound of the fan, it's the usual listening to **, just put it out loud, press the volume down button and it will be quiet.

It's why. It's because at first your ** is loud, and then you press the sign, which is equivalent to turning down the volume, so the volume is low.

No, for example, the volume was 18 before shutting down, and it was loud to turn the computer back on, and it was quiet when you pressed it.

Under normal circumstances, restart and turn on the computer, the sound goes back again, and the number is naturally smaller.

<>1、Check whether the multi** speaker has"Left and right channel balance knob",If there is a position adjusted to "0",It is the middle position。

, the volume on both sides is the same.

2. If there is no knob of the "left and right channel balance knob", then there is reason to suspect that the signal output by the computer is unbalanced. Make.

There are two possible reasons for this.

One is that the "balance button" on the **software has been inadvertently moved,The processing method is very simple,Just adjust the balance button of the **device back to the middle position,Take Qianqian Jingting (**) as an example。

The second is that the default data in the properties of the computer sound card can be artificially changed. Click the white "Small" in the taskbar in the lower right corner of your computer's desktop.

Speaker" icon, on the pop-up volume control panel, click the "Speaker" button, in the pop-up window, click "Level", click the "Balance" button.

Changing the values of the left and right channels to the same will restore the balance of the brigade. Click "OK", and the speaker will not be loud and quiet. Finish.

1.First of all, it is better to confirm whether there is a problem with your power supply and wiring, it may be that the interface contact is not in good contact.

2.Then there is the system settings, see if the equalizer of your ** software and the system volume are balanced between the left and right channel volume output, this mixer option in the audio manager in the control panel can be selected.

3.Right-click on the volume keys – a panel will appear,—— click on Sound – then tap Communication – select Don't do anything.

It is recommended to look for the following reasons:

1. The notebook is tilted, causing the fan blades of the fan to grind to the baffle.

2. There are too many windows open for high-power tools such as games.

3. There is a lot of dust at the computer fan.

4. If the computer is used for a long time without stopping and the computer motherboard is overheating, you should be careful at this time.

5. There are too many clutter around the computer, which affects the heat dissipation.

The system is win7, right? Right-click the sound icon in the lower-right corner and select Sound. In the dialog box that pops up, click Communicate, and then choose not to do anything when Windows detects communication activity, and that's it.

Reinstall the sound card driver, I guess the jitter affected the driver.

Is it that your rotation button to adjust the volume is not in good contact?

1.The volume potentiometer is dirty and aging, resulting in poor contact, this fault has a sudden feeling and is accompanied by a clattering noise when adjusting the volume, and the volume potentiometer can be replaced.

2。The output relay contact is aging, so that the output is in a semi-contact state, due to the contact resistance is too large, the output volume is weakened, and the change occurs under the influence of slight vibration or contact sparks, and the judgment method is to knock on the casing, if there is a change, it is likely to be caused by this.

3.For power amplifiers where the input signal is switched by a relay, it is also possible that the input contact is poor due to the poor quality of the input relay and the short lifespan, similar to the second type. If the input is mechanically switched, it may also be caused by the poor contact of the input switch switch, and the input switch can be repeatedly toggled to see if there is any change.

4. The possibility of virtual soldering of the circuit board is extremely small.

If you don't see either of these options in the dialog box, click on the "Options" menu - select "Properties".
