May I ask what is the reason for the loud noise in the box when the CPU usage is large?

The main engine design of the Lenovo Fengxing series is a chassis with a sophisticated suction-type air duct design, and there is a rotatable regulator on the front of the case, with three modes of full speed, medium speed and low speed, the light is red at full speed, blue at medium speed, and green at low speed.

The principle of the three rates is to determine the exhaust speed according to the actual occupancy of the CPU in real time, it is estimated that you are turned to red, if your CPU occupancy is high, all the fans in the machine are working at full speed, of course, it will sound badly, you try to rotate it through a grid, so that it becomes blue or green, it should not be so loud.

Your sound is loud because your CPU generates a lot of heat, and the fan speed will be faster, so the sound will be played, the solution, you can install a case fan on the case, which is conducive to heat dissipation, and the wires inside the case are raised to facilitate the case heat dissipation.

I don't know if it's ** ringing! Look at your configuration! I think it's good, there won't be a problem, I deduce that it might be your hard drive ringing again! You can listen carefully! It's either a CPU fan!

It's a fan. I don't think the CPU can be called.

The occupancy rate is high, and the CPU is hot, and the CPU calls the fan to fan the wind hard.

The fan will go off.

Fan? I didn't hear it, and I don't know why, isn't it a Karma sound??

This noise is generally caused by the internal fans of the host, including the power supply, CPU, and graphics card fans, and has nothing to do with the CPU configuration. Because of the long use time, the effectiveness of the lubricant inside the fan decreases, and there is more dust, the running speed of the fan decreases, and the friction increases. If the noise resonates with the chassis frame, not only the loud noise but the entire chassis will vibrate.

In addition, it is not excluded that the internal screws inside the chassis may loosen and cause noise, and there will also be noise when the mechanical hard disk is read and written.

Treatment suggestion: After a period of use, the lubricant inside the fan gradually recovers due to friction and heat, and the sound is reduced accordingly. If you don't see improvement, here's what you can do:

1. Use leather tigers, soft brushes, etc. to dust and lubricate the fan inside the case, or directly replace the new fan.

2. Tighten the screws on each part of the chassis.

3. If the mechanical hard disk is noisy, it can be replaced with a new hard disk or solid state drive.

1. CPU fan There is too much dust, which affects the rotational speed, so it is very loud.

Second, the graphics card fan has too much dust, which affects the speed, so it rings.

3. The power supply fan has too much dust, which affects the rotational speed, so it is very loud.

Fourth, the case fan has too much dust, which affects the speed, so it rings.

Fifth, the hard disk fan has too much dust, which affects the speed, so it is loud.

Sixth, the hard disk is aging, and the head rotates too loudly.

Maybe the CPU fan is dirty, blow it clean and try it, if it doesn't work, you have to replace it with a new one.

The startup sound of the computer cooling fan,It's not from the CPU.,Take out the fan and use a hair dryer to blow the dust on it.,The sound will be smaller.,If it doesn't work, change it.,It's not very expensiveMore than 60 one。

There will be no sound from the CPU, either from the hard drive or from the CPU fan. If the hard disk sounds, the hard disk may be broken, and the CPU fan may be too dusty, and it is time to clean the dust.

It's nice to share the worries of the landlord: first of all, please check if your CPU cable is mixed with a CPU fan, which is a very common thing. Then see if the CPU fan is loose, if it is loose, please fix it firmly (Generally, Intel's CPU is stuck on the motherboard, this phenomenon may occur, such as a corner is broken.)

The other thing is about the gray layer, because there is more gray layer on the wind blades, the resistance to the wind is greater, so the sound will be louder. If the above three points can be ruled out, then there is a possibility that the shaft of the fan has not been lubricated for a long time, this is actually not a big deal, and the general clear oil can also be used, but you have to slowly tear off the label on the fan first, and then you will see that there is a small hole, this is the place where the shaft is oiled, and a little oil can be stuck with a clean and fine thing to drip into it, and then please seal the label to avoid entering the ash layer.

If the landlord thinks that the sound is still very loud, then spend about 30 yuan to buy a fan of Jiuzhou Fengshen and install it, and the new one is much better!!

Maybe the CPU temperature is too high, and in order to cool down the CPU fan will speed up, so the sound will hit. You can consider adding a case fan to cool down, which will only cost a few dozen dollars. In this way, other parts can also be protected, so consider it.

1. The CPU fan will become loud due to dust and lack of oil for a long time, clean up the dust and add some oil to the fan bearing. Remember to be sure to remove the fan and add it, wipe it clean after adding it before installing it.

2. Change to a better brand fan, a good fan has a large caliber, sufficient air volume, small wind speed, and light sound.

The main thing is that your computer has not been cleaned for a long time, so there is a lot of dust on the fan, which hinders the normal operation of your fan a lot, so it should be fine to clean it up, or a little more dripping oil is better!

Turn on the case, get that seal off the CPU fan, and add some oil to it! Be careful not to add too much! If you're hardworking enough.

Then clean up the dust by the way! The main reason for the loud noise is that the fan is out of oil! If you're really afraid of trouble.

Come on. Go straight and buy a 50 fan and install it. This effect is absolutely silent!

If the fan goes off for a while after turning it on, it will be restored.

Problem explanation: This is some dust in the CPU fan! The wind from the CPU fan is blowing inward. So. It's been a long time. Naturally, there will be a layer in the shaft of the fan!

Generally, the above problems only need to add some oil to the CPU fan!

It will be restored after a while of powering it on!

If there is a wire stuck in the fan. It will make a loud noise!

You can go and open the host for yourself!

Clean up the dust in the machine, clean the fan, apply some lubricating oil to the fan shaft, and finally apply some silicone to the CPU and fan connection surface to see if it is better.

If it doesn't work, it is recommended to change to a better fan.

In summer, the temperature is high, and the fan turns fast.

The fundamental solution is to change the radiator. It would be much better to go to a computer store and buy a radiator for seventy or eighty yuan.

When the temperature is high in summer, the CPU temperature is high.

1.Replace a cooler fan, even a water cooler.

2.Install a case fan.

Downclocking (if you don't play big games and only surf the Internet).

First of all, let me tell you, to be precise, the CPU will not ring. If it does ring, your computer probably won't work.

The main components on the chassis that can make noise (squeak) are fans (power supply fans, CPU cooling fans) and hard disks, optical drives, and buzzers.

According to what you said, the CPU fan is too dirty and lacks oil. If you feel that you have a DIY interest, you can clean up the CPU fan well, open the oil cover (some are just a sticker) and drop a few drops of lubricating oil. After installation, power on and turn on, you will find that the effect is much better, but this effect can only last for about a year.

If you want to have a better effect, you can only remove the fan, go to the computer accessories market according to the model to find a fan with the right size as much as possible, and replace it with a new one will last longer.

If you think my suggestion is okay, take it!

It seems that the bearings of the fan blades were damaged during the cleaning. . . This suggestion is only to replace the CPU radiator, if you can find a matching CPU radiator fan can also be replaced, but it is recommended not to toss, now the radiator is not much money, buy a better one to replace it OK, I hope it can help you!

That heat sink is going to be used! Or the heat dissipation is not good! Your fan should be ringing!

You can change the fan, 5 yuan only.
