Why does my computer exhaust fan keep ringing?

Of course, it's a problem with the exhaust fan.

First of all, look at the dust of the exhaust fan, generally the exhaust fan has been used for a long time, the exhaust fan will accumulate a lot of dust, and even some small insects will hang inside, which will seriously affect the rotation of the exhaust fan, which needs to be carefully cleaned.

In addition, check the rotating shaft of the exhaust fan, the exhaust fan has been rotating for a long time, and there will be a certain mechanical loss of the rotating shaft during use, which will lead to inflexible rotation, and it will produce sound, and you need to add a little oil to the rotating shaft.

Third, check whether the fixed screws and chassis cover are loose, and the exhaust fan is loose when it rotates, causing resonance, and the sound will be particularly loud. The inspection method is to try to press on the different positions of the exhaust fan with your hands, or transfer the position, if you find that there is no noise in a certain state, it is loose in this part, and you can find a way to tighten it.

The reason is that the fan is broken, and there are several possibilities to say that it is accurate.

1. The fan has been used for a long time, and there may be gaps in the shaft of the fan with poor quality, and it will not rotate on the axis when it turns, and it will shake up.

2. Observe whether one of the blades of the fan is broken, if one or two of the blades are broken, there will definitely be a sound when it turns, although it is not as loud as in the first case, but the sound will get louder and louder.

3. See if the screws that fix the fan are loose, if you loosen the fan and remove it, and re-fix the moving position, you can save money to buy the entire radiator.

It's the same as my situation.、I changed the CPU fan and the fan of the graphics card.、Replaced it with a super quiet one.,The CPU is a fan of Kyushu.,Very good.、Just buy a graphics card.、It's all very easy to use.、It's not a matter of dust.、Don't go to some oil.,Oil is a very popular saying.,A lot of machines he can do this You may not be suitable.,So don't go to it yourself.、Just change a fan on it.,It's very cheap.,The two add up to no more than fifty.。

The problem with the fan, go change to a better one, it's better to buy a silent one.

Generally, the original fan of the computer CPU will be loud for more than 3 months.

And there are fans for the power supply.

You can drip some oil to solve it temporarily!

There's dust, it's time to wipe it.

It must be a problem with the fan, send it for maintenance and test the fan.

First of all, the fan rotates, and the system dissipates heat normally. If the sound is loud, it may be that there is a lot of dust inside and the heat dissipation is not strong, and the system will automatically increase the fan power, so it will ring and tell you to clean the ash. Generally, if the back cover can be disassembled, the ash is about 50, and the back cover can not be disassembled, and the ash is about 80.

Exhaust fan maintenance personnel must pay attention to the following points:1. The fan equipment can only be operated when it is completely normal.

2. If the fan equipment is started after maintenance, it is necessary to pay attention to whether all parts of the fan are normal.

3. Regularly remove dust, dirt, water and other impurities inside the fan and gas transmission pipeline, and prevent corrosion.

4. The repair of fan equipment is not allowed to be carried out in operation.

1、Because the motor of the exhaust fan lacks lubrication, the fan blades of the exhaust fan cannot be rotated, and this phenomenon is easy to occur after a long period of use.

Due to the damage of the capacitor, the exhaust fan lacks power, which slows down the speed or stops working directly.

Due to poor contact of the power supply, or aging of the power cord, the contact is poor and cannot be powered.

Precautions for the use of exhaust fans:

1. Place the exhaust fan horizontally: the exhaust fan should be parallel to the ground and not tilted, otherwise it will affect the use effect, and it is best to check whether the power supply is consistent with the parameters on the nameplate of the exhaust fan before use.

2. The exhaust fan should be cleaned frequently: the exhaust fan should be cleaned for the first time, and if it is not used for a long time, it should also be cleaned. When using it normally, it is best to clean it every 2 months, and never use a hardness brush when cleaning to avoid damaging the surface.

3. The exhaust fan should be humidified with humidity: if the air you want to send out is cold air, humidification is necessary. It should be noted that the power plug should be unplugged before humidification and then wiped with a damp cloth.

4. The exhaust fan should swing to supply air: Generally, the fan blades of the exhaust fan rotate clockwise, if you want the wind force to become larger, you can adjust the air supply position, but it should be noted that the fan blades should not be deformed, otherwise it will affect the rotation, and even cause more serious consequences, such as the fan blades are broken, and the exhaust fan cannot be used.

There are several possible reasons for the main noise, one is that the exhaust fan and the ceiling are not fixed and absorbed, causing the vibration of the exhaust fan to be amplified through the ceiling, the second reason is that the air duct of the exhaust fan is blocked, generally the check valve is not opened normally, or there is something blocked in the exhaust fan, the noise of the exhaust fan becomes larger, the speed is also very large, and the noise is naturally big. In addition, if there is a problem with the motor or impeller of the exhaust fan, it will need to be replaced with a new exhaust fan, and the static electromechanical technology can provide you with answers to various problems encountered in the use of exhaust fan products.

The reasons are as follows: 1. The fan blades of the computer's cooling fan have accumulated a lot of dust, the fan blade load is heavier, and the heat dissipation capacity becomes weaker. As a result, the sound becomes louder and the time becomes longer during operation.

Solution: Go to a professional computer repair shop and clean the ash.

2. If the computer is not used for a long time, the lubrication at the fan shaft becomes worse and the running resistance increases. This leads to poor heat dissipation and longer running time.

Solution: Find a professional to disassemble the machine, and purchase special lubricating oil to lubricate.

3. Software problems. There is a lot of software open at the same time, the computer is working at full capacity, the heat increases, and the fan continues to work.

Solution: Close some software, and don't start a lot of software to solve the problem.

Summary. 1. There are too many computer running programs, the power increases, the fan speed accelerates, and the sound becomes louder. Workaround:

Reducing the number of programs that run at one time is sufficient. 2. The computer has too much dust, which causes the fan to become louder. Workaround:

Just clean up the dust from your computer. 3. The fan lacks oil, resulting in excessive fan sound. Workaround:

Lubricate the fan or replace it with a new one. 4. The fan in the case is loose, and the fan resonance causes the sound to be too loud. Workaround:

Re-tighten the fan in the case.

The computer exhaust fan keeps ringing.

As soon as I turn on the computer, the exhaust fan keeps ringing, what's going on?

1. There are too many computer running programs, the power increases, the fan speed accelerates, and the sound becomes louder. Solution: Reduce the number of programs that can be run at once.

2. The computer has too much dust, which causes the fan to become louder. Solution: Clean up the computer dust.

3. The fan lacks oil, resulting in excessive fan sound. Solution: Lubricate the fan, or replace it with a new fan.

4. The fan in the case is loose, and the fan resonance causes the sound to be too loud. Solution: Re-tighten the fan in the case.

There's too much dust inside, clean it up, open the back cover, and blow it off with a hair dryer.

Half the time is too dusty, it will be like this, and there is a lack of lubricating oil

If the sound of the fan is particularly loud, it will affect our experience of using the electric car brain, which is very annoying, especially the computer fan has been ringing non-stop, and I don't know what the reason is, in fact, this is mainly related to the heat dissipation or fan performance.

Method 1:

1. First of all, disassemble the chassis and listen to the fan that is ringing non-stop.

2. After finding the corresponding position, disassemble the part and clean up the dust.

3. If yescpuFan, then it has to beReplaceFans, other fans can be cleaned.

Method 2:

1. The oil of the fan is also critical to noise control.

2. After finding the fan that keeps ringing, tear the middle membrane to add oil.

Method 3:

Loose partsIt will also cause the sound to stop because the fan is turning.

2. Check if there are any loose places, especially the vents.
