The sound of the fan is loud and small, and the fan wind will be big and small

In this way, you will understand that there is indeed a problem with your fan, but when your computer is standby, the CPU usage is low, the fan speed is low, the CPU is used a lot, the fan speed is fast, if it is a normal fan, whether it is fast or low, the sound is not so obvious, and there is not so much noise.

However, your current fan is old, or it is short of oil, the CPU usage is high, and the fan is spinning fast, so you hear the noise.

1. The CPU fan of the motherboard is intelligently controlled in normal operation. Open what programs, software, CPU tasks are heavier, the heat rises, and the fan is asked to speed up. It's the opposite when the CPU is idle.

2. Maybe you are an old machine, if this phenomenon was not obvious before, it is the aggravation of the wear of the fan shaft or the lack of lubricating oil. The noise increases significantly when it is told to run.

You can listen closely, there are two kinds of louder sounds: wind sounds, friction vibration sounds, you see which one it is. Estimate that the probability of you changing the fan is higher.

Mine: Our company's machines are sometimes like this, it's okay, don't worry!

Because as soon as you operate the computer, open the application, naturally want to start the CPU, then the CPU will inevitably become hot, and the fan will definitely spin up, if you don't clean it for a long time, there will be some dirty things around the fan, inside and outside the rotor bearing, sludge or something, so the sound will be different, and it will be louder at this time, and the more programs you open and run, the louder it will be! When the CPU is not busy, it will naturally be quieter!

There is also the fact that you can go online to find some software similar to speedfan, Sky Software** has it, which can partially solve your problems, and change the settings in the BIOS, but the effect is not particularly great! If it doesn't work, you can only change the fan, I hope it can help you!

The sound of the fan is related to the speed of the fan, and the faster it turns, the louder the sound.

The fan speed is related to the CPU temperature, the higher the temperature, the faster the rotation.

It's time to oil the fan.

There is this function in the BIOS.,Turn it off.,Forget what's called.。 Look at it, you should be able to understand English if you know it.

What is the reason why the fan is very loud.

Because it was usedElectric fanThe function of the natural wind or the sleeping wind.

The electric fan of the remote control series has three functions: ordinary wind, natural wind, and sleeping wind, and the air volume of ordinary wind is constant, and there will be no big or small; The natural wind is mainly aimed at the wind force of nature, which is large and small, and simulates the control circuit that can periodically change from strong to weak, and then controls the speed of the motor to be fast and slow; The principle of sleep wind is the same as that of natural wind, and it also uses a control circuit from strong to weak to control the speed of the motor.

Attention should be paid to electric fans in use:

1. Read the instruction manual in detail before use, and fully grasp the structure, performance, installation, use, maintenance methods and precautions of the electric fan.

2. After the electric fan is used for a long time, the bottom of the fan blade is easy to be stained with dust, which is due to the friction between the running fan blade and the air so that the fan blade carries static electricity, which is easy to attract fine dust floating in the room. The oil or dust accumulation of the electric fan should be removed in time, and a neutral detergent and soft cloth should be used for cleaning to avoid damaging the surface or coating of the shell. When disassembling and assembling the fan blades, pay attention to protect the fan blades and do not deform the fan blades to avoid vibration or shaking when the fan is running.

3. If there is a fault such as hot hands, abnormal burnt smell, or slow speed of the electric fan during use, do not continue to use it, and cut off the power supply in time for maintenance.

4. When using electric fans in summer, avoid blowing for too long and too strong after the heat, it is best to use shaking head, low speed, and natural windshield, and sleep with the wind when sleeping.

5. Families with children should pay special attention to the safety of the use of electric fans, place the electric fans in places that are not easy for children to touch, and educate children at home not to touch the fan blades out of curiosity to prevent accidents.

There are several reasons why the fan wind will be big and small, the first may be caused by the voltage instability in the area, the second point may be that the fan has been used for too long, the motor bearing is seriously worn or the lack of lubricating oil is made, and the second is that there is a problem with the capacitance of the fan.

First of all, let's take a look at how to solve the noise problem caused by the fan. There are many reasons why fans can cause a lot of noise, so let's take a look at each of them. If the noise of the computer fan is usually very small, but when the high load is running, the sound of the fan becomes louder, which is generally due to the performance of the fan can not meet the needs of the processor or graphics card heat dissipation, the current cooling fan can automatically adjust the speed, when the processor or graphics card heat is low, the fan will rotate slowly, when the computer is running at high speed, the heat will increase, the speed of the fan will be accelerated, then the fan will make a loud sound, to solve this problem you need to replace the heat sink with better performance, Or replace it with a silent fan.

If the fan suddenly makes noise after a long period of use, it is generally caused by the loose fixation of the fan or a lot of dust, you can open the case to clean up the dust and reinforce the loose fan in the case.

Switching to an SSD is a solution to the problem that the mechanical hard disk reads and writes is a way to make noise once and for all, but the cost of this solution is too high, and our solution can only be to put the mechanical hard disk at the bottom of the chassis, away from the noise source.

If the hardware has passed the shelf life, you can try to use 502 glue to drop into the inductor that emits the acoustic noise, and the coil can also be fixed to reduce the acoustic noise, but this method is risky, and any adverse consequences occur, and the good thing is not responsible.

1.The speed of the fan is intelligent.

2.When the temperature inside the case is high, the fan speed is relatively fast, and the sound is louder.

3.If the temperature is low and the minimum is the rotational speed, the sound will be quiet.

4.Especially when playing games, the graphics card fan and CPU fan speed are very fast, and when working on documents, it is very quiet, and this is the reason.

Use 360 Security Guard, Master Lu and other software to optimize the program again, uninstall unnecessary programs and slim down the system. It will be of some help to your machine, and the rest will be difficult to do, clean the fan, you can't do it yourself, you can only let the after-sales service help you get it.

1.The speed of the fan is intelligent.

2.When the temperature inside the case is high, the fan speed is relatively fast, and the sound is louder.

3.If the temperature is low and the minimum is the rotational speed, the sound will be quiet.

4.Especially when playing games, the graphics card fan and CPU fan speed are very fast, and when working on documents, it is very quiet, and this is the reason.

Your CPU fan is a smart fan.

You can set the temperature of the CPU by yourself, which can generally be set in the motherboard BOIS, for example, if you set the average temperature to 45

Full load temperature 48

Turn off the system temperature 60

So, if your computer's CPU temperature is below 45 degrees, the fan speed will be low, and the noise will be very low.

If your computer's CPU temperature is higher than 45 degrees, the speed of the fan will slowly increase to 48 degrees, when the fan is running at full capacity.

At this time, of course, the noise is the highest!!

Turning off the system temperature has nothing to do with the fan speed.

This is just to protect the CPU, in case the fan is broken, the temperature will continue to rise to the set 60 degrees, and the computer will automatically shut down.

In addition, the temperature of the CPU has a lot to do with the number of programs running on the computer, and the standby temperature of my computer is 37 degrees (fan 1500 rpm).

I play a game and open a number to 42 degrees (1800 rpm) after a while, and open three numbers to 52 degrees (2400 rpm)!!

The most awesome one is 57 degrees (5600 rpm).

There are usually several possible reasons why a computer fan suddenly becomes louder:

1.The fan itself is aged or damaged. Computer fans will deteriorate and wear out after long-term use, and damage to bearings and other components can lead to increased fan loudness or vibration. At this point, you need to replace the fan to solve the problem.

2.The radiator is clogged. The CPU fan is responsible for taking away the heat generated by the CPU, and if the cooler is clogged with dust and other debris, the fan needs to increase the speed to enhance the heat dissipation, which will cause more noise. Dust needs to be cleaned from the radiator.

3.The temperature sensor is out of order. The computer will automatically adjust the fan speed according to the CPU temperature, if the temperature sensor is damaged, the fan speed will be abnormal, resulting in louder noise. You need to replace the temperature sensor that comes with the motherboard or fan.

4.CPU overheating shouts. If the CPU is working at high temperatures for a long time, the fan will inevitably spin faster to enhance heat dissipation, which will also cause the fan to become noisy. You need to check the CPU usage and cool it down.

5.The fan speed is not set properly. If the fan speed control option in the motherboard BIOS is not set properly, the fan speed will be too high and noise will be generated. Go to the BIOS and restore the fan speed setting to default or lower.

6.Fan wiring is loose or in poor contact. If the speed signal cable or power cord of the fan is not in contact properly, it may also cause the wind to seep into the fan and cause noise due to abnormal operation. The fan needs to be removed to check the line contact, and replace the fan if necessary.

In summary, there are many reasons why a computer fan suddenly becomes louder, and the common ones are fan damage, radiator blockage, temperature sensor failure, CPU overheating, and fan setting problems. You can try to troubleshoot the fault according to the noise characteristics of the fan, or take it directly to the maintenance center for detection to determine the root cause of the fault, and repair or replace the fan to solve the problem.

In this case, it is very likely that the motor of the electric fan is faulty or the blades are unbalanced, so it is best to check and repair it in time.

To solve this problem, you first need to check whether the motor of the electric fan is working properly. If the motor fails, it will not be able to adjust the wind speed of the electric fan normally, and the wind force will be unstable or small. In this case, the motor needs to be replaced or repaired to solve the problem.

Another possibility is that the blades are unbalanced, in which case the fan will vibrate when it is running, making the fan speed unstable, and it will also lead to a situation where the wind is large or small. To solve this problem, you need to remove the blades of the electric fan, check whether the blades are deformed or loose, and then reinstall and balance the blades.

In addition, if this abnormal situation occurs in the electric fan mountain, it may also be due to the unstable power supply voltage, you can try to replace the power supply or tease the hood to find the power supply problem. In a high-temperature environment, the electric fan will cause motor failure or leaf deformation due to long-term operation, so try to avoid using the electric fan for too long in summer.

In short, when there is a problem of unstable wind power of the electric fan, it is necessary to check whether the motor is working normally and whether there is any unbalanced blades in time, and repair and replace it in time. In addition, strengthening the management and maintenance of the power supply can also reduce the occurrence of electric fan failures. <>

The reason why the electric fan is loud and windy is because the blades of the electric fan are loose or worn, which makes it impossible to effectively push the clean air to the outside. In addition, if the motor fails, it will also cause the electric fan to make loud noise. If the fan is used for too long or is poorly cleaned, it will also cause dust and impurities to accumulate in the fan blades, which will reduce the efficiency of the fan fiber.

By extension, the sound of the electric fan may also be related to the power supply voltage. This happens when the wires and plugs are not properly connected and the power supply voltage is low, and the electric fan will not reach its maximum efficiency. In addition, electric fans made of composite materials are quieter before digging than electric fans made of plastic.

The technology and process used in the manufacture of composite materials are more advanced, lightweight, and have better loss performance, which can effectively reduce the noise of electric fans.

In order to prevent the problem of high sound and low wind of electric fans, we need to frequently check whether there are loose parts or blocked by dust and impurities. Make sure to clean the fan regularly and use a stable voltage plug to avoid problems caused by voltage instability. In addition, it may be better to buy an electric fan made of composite materials.

Finally, if the electric fan is already making abnormal sounds, we should solve the problem as soon as possible to avoid motor failure and prolong its lifespan. <>
