The motherboard fan is noisy, does the fan noise have anything to do with the motherboard?

This problem is also simple to deal with.

First of all, you need to determine where the fan is ringing.

There are nothing more than fans in five places in the computer.

Fan 2Fan of the motherboard chip3Power Fan 4Graphics Fan 5Case fans (depending on the situation, most computers will have a few of these).

First of all, you have to determine which fan is ringing. This is very simple, open the chassis to let the machine run normally, after turning on the machine, manually stop any fan by hand (be careful not to scratch your hands), and then listen to see if the noise disappears. If it weren't for another noise point (fan) to eliminate them one by one, of course, the power supply should not be able to get it.

Because it is dangerous to have a high-voltage resistor inside, it is recommended to eliminate it at the end. In this way, safety comes first to avoid danger. As for whether the fan will be broken, you can rest assured, as long as you are gentle enough to hold it for a few minutes, I promise it will not break.

Once it's decided, it's solved.

Well, this problem can generally be solved by debugging in the BIOS, such as turning on the "cold and quiet" la, debugging the smart fan, etc., you can refer to the motherboard manual. If it doesn't work after debugging, it is recommended to change to a silent fan, which is generally less than 100 yuan. 2.

The problem with the motherboard chip fan, I think this possibility is more likely, I just checked the small fan on the motherboard of Dingxing, this motherboard is really chicken, this kind of fan is easy to break. It is recommended to directly replace it with an aluminum heat sink. It doesn't cost a lot of money, but you need to go to the second-hand market.

3.There's no good way to do this power fan.,If you're in the insurance, send it for repair.,If you can't fix it, change it.。 Hangjia's calm king, the silent master of the Great Wall, how good, other brands are recommended not to buy.

4.The graphics card fan is just to change the fan, and how much money should be found when you go to the second-hand market, this depends on the model of the graphics card. 5.

The case comes with a fan, the solution is simple, it's almost life-threatening, just unplug it.

Northbridge cooling fan! You can change to a fan that is quieter! You can also change to a passive heat sink!

Northbridge heat dissipation! You can take a look.

Around 50! That's it! Expensive around 100.

Problem description: I just changed a few capacitors two days ago, and then the fan became louder. Just bought a ball fan.

Analysis: There is a CPU temperature detector on the motherboard, if the CPU temperature is too high, it will speed up the CPU fan, and if the fan speed increases, the sound will naturally be louder, so it cannot be said that the fan noise has nothing to do with the motherboard, but this is a normal phenomenon.

In addition, based on my experience, there are several possible reasons for the noise of the fan to increase significantly:

1. Due to weather conditions, usually when the computer is at a low temperature start, the motherboard will increase the speed of the CPU fan to make the fan run more smoothly, but it will reduce the speed after a while.

2. There is a problem with the fan itself, especially the ball fan, if the mechanical part (ball bearing) has serious wear and external force damage, or there is too much dust on the fan, causing the fan to rotate unbalanced, then it is not surprising that there is noise.

3. The voltage of the fan interface is too high, which must be checked by a professional instrument.

4. The sealing of the chassis is not good, resulting in great resonance, the chassis is like a loudspeaker that will amplify the very small noise through its own vibration, and the fan must be tightly combined with the heat sink (that is, tighten the screws) to avoid unnecessary vibration.

Clean the fan more often, and remember to oil it at least once a year.

I believe that if the above possibilities are ruled out, the computer will be much "quieter", hehe

Hello dear, there are several ways to solve the problem of noisy fans of computer hosts: Replacing radiator fans Radiator fans are often one of the main culprits of noise in computer hosts. If your computer's main computer fan is noisy, it is recommended to replace it with a cooler fan with quieter performance.

When purchasing, you can choose a product with a noise test report to ensure that it really has a good silent effect. If you do not clean and maintain the computer for a long time, dust accumulation may affect the air circulation inside the computer, resulting in a decrease in the cooling performance of the computer host, and noise caused by the increased workload of the radiator fan. Therefore, it is recommended to clean the inside of the computer regularly, including the radiator fan, motherboard, graphics card and other components to ensure the normal operation of the computer and reduce noise generation.

Reducing the fan speedReducing the fan speed is another effective way to reduce noise. This can be done through BIOS settings, third-party software, or some heatsink fan controller with hardware control. Note that reducing the fan speed may affect the cooling capacity of the computer, so you need to set reasonable parameters according to the actual situation.

In addition to replacing the radiator fan, choosing a high-quality computer chassis with good materials is also a good way to reduce noise. Generally speaking, the larger the internal space and the thicker the material, the higher the stability and noise reduction ability. Summary:

The above are several ways to solve the problem of noisy computer fans, which are replacing the radiator fan, cleaning the inside of the computer, reducing the fan speed, and replacing the computer case. It is recommended that users take corresponding measures according to their actual situation. I'm glad to answer for you, and I hope I can help you.

Summary. First of all, to rule out the possibility of dust on the heat sink and radiator, you can use a vacuum cleaner to clean the dust on the heat sink and radiator at the bottom of the case to reduce the noise of the fan. Second, you should check the fans in your case, the noise of these fans can be mitigated by replacing the low-noise ones.

Finally, acoustic insulation can be installed inside and outside the chassis to reduce noise while ensuring that thermal performance is not compromised. 

The computer shows no signal.

So what to do. I paid for it all.

Textual description. Don't be in a hurry.

Dear, refer to the above The computer host fan is noisy, you refer to the above.

Solution to the noisy computer fan: Clean up the dustThe small fan installed in the computer case will slowly accumulate dust on its blades and surfaces during use. When the dust gets bigger and bigger, and it is not cleaned up in time, the resistance will increase when the fan rotates, resulting in the fan being louder and louder.

This is a computer fan failure caused by dust blockage, and we can clean the fan in time on a regular basis. Lubrication bearings are the most important part of fan rotation. If the hinge is rusty, it can also cause the fan to make a lot of noise.

At this time, we only need to put a few drops of lubricating oil on its bearings at the beginning. If there is no lubricating oil, you can use sewing machine oil instead, but you must not use edible oil instead, because edible oil particles are large and easy to damage the bearing. Re-fix the fan blade If the screw fixing the fan blade is loose and the installation is not firm, there will be noise or even vibration when the fan is working.

In this case, we need to take the computer fan apart and re-tighten all the screws on the fan blades so that the fan blades are fixed firmly so that there will be no vibration sound. Polishing the fan bladesSome computer cases come with poor quality cooling fans. Due to a defect in the manufacturing process, the center of gravity of the fan blades may not be on the axis, creating an "eccentricity".

It may not have an effect at first, but after long-term use, the "eccentricity" of the fan blades will become more and more serious, resulting in a loud fan and even damage to the CPU. If the fault is caused by the "eccentricity" of the fan blades, we need to remove the fan, tie it to its ** position with a thin wire, hang it in the air, and see which direction it sinks after it is stationary. Gently grind the sinking end on the grinding wheel a few times and then perform a lift test until the fan can be in a horizontal position.

This method is more troublesome, and friends who do not have the conditions can directly choose to replace a computer fan with better quality. Check the cable of the case, clean up all kinds of cable in the case of foreign objects, if you touch the cable when the fan is turning, there will be a big noise problem. After we open the case, we double-check the cables inside, and only need to rearrange the cables or if they may touch foreign objects from the fan.

Upgrade the computer system configurationIf the computer configuration is too low, such as the computer power supply is aging, the computer is running at full capacity, etc. It could also be a fault with the loud voice of the computer fan. At this time, we can upgrade the corresponding computer system configuration according to the actual situation to solve the problem.

There are the following ways to solve the problem of the motherboard fan sound humming and shaking.

Check whether the fixed place of the fan is tightened!

The temperature of the CPU is only 30 degrees, visible to you, the fan is normal, no problem!

Check out the other fans! The fans of the graphics card and power supply will also make a lot of noise.

There is too much dust, it is recommended to clean it up by yourself, I just do it myself, it's really simple, don't go to some specialty stores to clean up! It's only about ten yuan to buy a dismantling notebook screwdriver set yourself! Unscrew the forehead screw fan at the back and it will be exposed, just clean it up with a paper towel alcohol swab.

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, you can use a vacuum cleaner to suck the dust off the fan so that you don't have to turn on the power.

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.
