How to reduce noise if the case fan is too noisy, and how to reduce noise if the computer fan is too

Change the brand of fan, the fan sound of the general brand machine is relatively small, because the fans of the brand machine are produced by relatively large manufacturers, the fan is large, and the speed is low, and the noise is almost none.

One is to replace the fan directly, and the other is to refuel the fan shaft, and a sticker in the center of the fan shaft is removed to reveal the shaft with butter at this time. Turn the fan impeller a few times with your hand, and the impeller is smooth.

Case fan noise is too noisy solution:

1. Fan type.

First of all, you need to understand what kinds of computer fans there are, one is the computer power supply fan, the other is the computer CPU fan, and the additional chassis cooling fan. Compare these different types of fans to find a way to reduce noise.

2. Secondly, let's talk about the computer to the CPU fan first, because the CPU is the computing core of the computer, and the CPU will generate a lot of heat when it is calculated, which is dissipated by the CPU radiator, and the cooling fan and the heat sink can play a role in heat dissipation.

Fan brand, usage time, how much dust, BIOS settings, etc. need to be checked.

There is a decorative material called sound-absorbing cotton that is sold online. Wrap the machine up with this and solve the noise perfectly. Is sound-absorbing cotton too expensive? It doesn't matter, those corrugated cardboard boxes that receive express delivery, split from the middle with that material, are also good materials for absorbing sound.

Actually, it's better to do without a case fan. Directly remove the side cover, and if you want a better effect, find a fan to blow on the entire case.

How to fix that the computer fan is too loud:

1. If the computer fan noise is caused by dust clogging, then the user can solve the problem by doing a big cleaning of the computer fan.

2. If the noise of the computer fan is caused by the rust of the oil shortage shaft, then the user can solve the problem by giving the computer fan shaft several more times of oil.

3. If the computer fan noise is caused by the eccentricity of the fan blades, then the user can solve the problem by reinstalling the fixed computer fan.

4. If the computer fan noise is caused by foreign objects, then users can solve the problem by cleaning up foreign objects. If the computer fan noise is caused by aging the low level of the computer configuration.

, then the user can solve the problem by upgrading the computer system configuration.

Hardware purchase suggestions:

At any time, "buying new" is also our solution to the problem. If you're building a new PC, or you're planning to upgrade some of its accessories, and you want to be quiet.

The smaller the chassis size, the stronger the hardware performance, and the higher the operating noise of the host. Small-size chassis with small volume or special structure often have limited radiator size and cannot form a good air duct; The stronger the hardware performance, the higher the power consumption, the more waste heat is generated, and the core heats.

The hardware (CPU graphics card) requires a higher speed fan for heat conduction.

Resulting in increased noise. The main impact is on high load conditions.

Introduction to the solution to the loud fan of the case:

1.Organize and sort out the cables inside the chassis.

If the power cable and hard disk data cable touch the fan inside the case, it may also cause excessive noise to the fan, so you need to tidy up the cables near the case fan so that they do not touch the case fan.

2.Dust and ash removal.

If too much dust accumulates on the case fan, it may not be able to rotate and cause noise. There are many ways for dust to get into the case, from the air intake as well as from the bottom. When a certain amount of dust has accumulated on the fan, a vacuum cleaner can be used.

Suck dust off the fan so you don't have to turn the power on.

3.will be strong radiator capacity.

In addition to the fan, there is also a heat sink that cools the computer. If the case fan is too loud, you can use the power of the radiator to make the fan run at low speed, so that the temperature can be effectively controlled, and the replacement radiator can be silent.

Introduction to the reasons why the case fan is too loud:

1.When the computer is turned on, the parts inside the case are touching the fan.

2.The graphics card, power supply, graphics card, or other accessories in the case need to rotate during the heat dissipation process, causing the fan to vibrate and make sound.

From this point of view, the most affected by the excessive sound of the case fan is the cooling system, and the fan will make sound if it does not rotate properly. However, the most important equipment in the computer is the heat dissipation device, we can not remove the heat dissipation equipment to solve the noise, but need to start from other aspects, so as to extend the service life of the computer.

Summary. 1.Replace the fan:

Replace the built-in fan with an energy-efficient water-cooled fan, which is less noisy and dissipates heat better. 2.Plus soundproofing cotton:

Use professional soundproof cotton on the cabinet and the fan junction, which can greatly reduce the noise of the case fan. 3.Replacement Cabinet:

Buy a case with better acoustic characteristics of the case fan, which has better sealing performance and can effectively suppress the noise of the case fan. 4.Install the muffler:

A muffler can be added to the outside of the case to suppress noise inside the case and maintain the high efficiency of the cooling system, thereby reducing the noise of the case fan.

How to reduce noise if the case fan is too noisy.

1.Replace the fan: Replace the built-in fan with an energy-efficient water-cooled fan, which is less noisy and dissipates heat better.

2.Add sound insulation cotton: Use professional sound insulation cotton on the box and the contact of the fan, which can greatly reduce the noise of the case fan.

3.Replace the chassis: Purchase a chassis with better acoustic characteristics of the case fan, which has better sealing performance and can effectively suppress the noise of the chassis fan.

4.Install a muffler: You can add a muffler to the outside of the case to suppress noise inside the case and maintain the high efficiency of the cooling system, thereby reducing the noise of the case fan.

After the computer is turned on normally, is the sound of the fan very small, I have used this machine for five or six years, and now the sound of the fan blades turning in use after booting up feels obviously a bit loud.

Go and clean the ashes.

Dust has piled up.

The CPU is old.

Running a large game can be overwhelming.

Can I optimize this computer? Desktop.

If you want to optimize, the CPU, graphics card, and memory have to be replaced.

When the fan is working, it will produce a certain sound due to the rotation of the fan and the flow of air, which is a normal phenomenon. The rotation of the fan is related to the temperature of the CPU, such as the use of high ambient temperature, too many running programs or large software will cause the CPU temperature to rise, when the CPU temperature increases, the fan will rotate more frequently, and the sound will be louder. If the sound is particularly loud or you feel that it is abnormal, it is recommended to go to the nearest official service center to test and confirm, and it is better for the engineer to test it on site.

If you are not a professional, do not remove the parts of the fan yourself, so as not to cause electric shock, or the phenomenon of **, because the fan has many lines, non-professionals should not touch, in fact, when buying a fan, try to buy a more expensive fan, and the use time will be longer.

The noise of the fan may be due to the long running time of the bearing, lack of lubricating oil, at this time you can drop a few drops of lubricating oil on the bearing of the fan, if there is no lubricating oil, you can use the oil of the sewing machine instead, it should be noted that you must not use edible oil to replace, because the particles of edible oil are relatively large, easy to damage the bearing.

If the fan is used for a long time, there will be a lot of noise, this is because the bearing of the fan lacks lubricating oil, as long as a few drops of lubricating oil can be solved, if it can't be solved, it is likely that there is a problem with the fan itself, and it needs to be sent to the place where the household appliances are repaired for maintenance.

There is another reason for the noise of the fan, perhaps because the screws on the bearing are relatively loose, as long as the screw buttons are tightened and firmly fixed, they will not vibrate again.

Use and maintenance

Before use, you should read the instruction manual in detail to fully grasp the structure, performance, installation, use and maintenance methods and precautions of the electric fan.

Desktop and floor-standing electric fans must use three-pin plugs and sockets with safety grounding wires; The ceiling fan should be installed at a higher position on the ceiling and can be installed without a grounding wire.

The fan blades of electric fans are important components, and they must be protected to prevent deformation during installation, disassembly, scrubbing or use.

When operating various function switches, buttons, and knobs, the action should not be too violent or too fast, nor should two buttons be pressed at the same time.

The speed control knob of the ceiling fan should be rotated slowly and sequentially, and should not be rotated in the position between the gears, otherwise it is easy to make the ceiling fan heat up and burn in.

The oil or dust accumulation of the electric fan should be removed in time. Do not wipe with gasoline or strong lye to avoid damaging the function of the surface painted parts.

If there is a hot hand, abnormal burnt smell, ineffective shaking head, slow speed and other faults in the use of the electric fan, do not continue to use it, and cut off the power supply in time for maintenance.

Before storing the fan, the surface should be thoroughly removed from the oil and dust, and wiped with a dry and soft cloth, and then wrapped in kraft paper or clean cloth. The storage place should be dry and ventilated to avoid squeezing.

Electric fan is too noisy to reduce noise method:

1. If it is caused by loose accessories, you can check all parts of the fan to see which part of the accessories are loose, and then tighten and install them.

2. If it is caused by the lack of lubricating oil in the bearing, a few drops of lubricating oil can be applied to this part to solve the noise problem.

3. If it is caused by too much dust accumulation inside after not being cleaned for a long time, you can use a tool to disassemble it, and then clean it as a whole, and then install it.

4. If it is caused by damage to the internal motherboard, you need to ask a professional to repair it.

The functions of the electric fan are:

A fan is a device that generates air and generates air flow by using electricity to drive an electric current through the fan installed inside and rotate it, so that it has the effect of enjoying the coolness.

Household electric fan: After powering on the household electric fan, the internal configuration of the fan will rotate into a natural breeze to achieve a cooling effect.

Industrial exhaust fan: mainly used for forced air convection. If you use an electric fan for a long time, it will be easy to get a lot of dust under the blades.

This is because when the electric fan works, the blades and the air rub against each other, and the blades will be electrified, and the charged object has the property of attracting light objects and can absorb the fine dust floating in the room.

In general, most of the cases are generated by the internal fan and hard disk vibration, etc., for the buzzing noise of the case, it is easy to affect the mood of surfing the Internet, whether it is in study or in games, noise is the most annoying to everyone. Hopefully, the following article can help you solve the corresponding troubles!

Generally speaking, the chassis noise mainly comes from the following three aspects, as long as we develop good computer maintenance habits, regularly clean up the dust of the computer, check whether there is resonance inside the chassis or whether the fixing hardware screws are loose, etc., can effectively avoid the occurrence of excessive noise in the chassis.

One: The case noise comes from the cooling fan

We know that usually CPUs, graphics cards and power supplies have cooling fans, these three hardware after a long period of use, the surface of the cooling fan usually produces more dust, which not only affects the heat dissipation capacity but also produces noise, the solution is to clean the cooling fan of these hardware processors, if there is a heat sink due to a long period of use, the fan rotation flexibility is not enough, you also need to help it add some wheel oil processor, these can significantly reduce the fan noise.

Two: The chassis noise comes from the hardware resonance inside the chassis

Since the noise produced by the resonance is often accompanied by a buzzing sound, we can try to touch the hard drive and the optical drive with our hands to see if the vibration is too bad, and if so, we need to dampen the chassis processor. For the chassis, it itself is the quietest of the many accessories', but because other accessories are installed, it becomes a hub for all noise. For example, in inches and inches**, there will be resonance due to the vibration of the hard disk and optical drive when working, and the side panels, front and rear panels and other parts will also resonate due to the rotation of the fan.

The easiest way to deal with these resonances is to tighten their mounting screws.

If there is still a lot of noise, you can install shock-absorbing pads, shock-absorbing nails, etc. in the part where the accessories are in contact with the chassis. The sound-absorbing cotton can also be laid in the case, so that the sound in the case is absorbed by the sound-absorbing cotton and will not be refracted and will not be refracted, so as to reduce the noise to a minimum, usually 6cm thick sound-absorbing cotton can reduce the volume by 10 to 15 decibels. 3M sound-absorbing cotton was once used for noise reduction in car interiors, so the mute effect is very good.

When laying sound-absorbing cotton, it needs to be cut according to the size of the inside of the specific chassis, and it is important not to block the heat dissipation holes.

Some users are afraid that the computer is too hot, so they install multiple 8cm fans in the case, but the temperature not only does not drop much, but is unbearable. This is because adding fans indiscriminately disrupts the air ducts inside the chassis and affects the heat dissipation. In fact, you only need to install a low-speed and quiet 12cm fan on the front panel, which has a higher heat dissipation efficiency and can reduce the number of fans used, thereby improving the noise problem of the case.

Three: The case noise comes from the internal wires touching the fan

The last point here is to add that sometimes, such as the hard disk data cable and power cable, if it touches the CPU fan or graphics card fan, it will also produce relatively loud noise, and the solution is to comb the cable that touches the fan, and try not to touch the fan.
