My laptop was always ringing and humming like a car walking

I think your computer has been bought since now.

I don't have this book internal cleaning!

Your notebook is not particularly loud from the fan outlet now.

That's because the heat vent is blocked by dust.

I suggest you go to the after-sales service to clean the ash.

I'm trying. And let them check your CPU fan to see if the fan is aging.

It's time to clean up. There shouldn't be any major problems.

It's okay. If you believe me.

Just hurry up and go to the after-sales service to clean the ash once.

Normal depends on your practical environment.

The ash should be cleaned once every 1-3 months.

It is normal for the laptop's fan to produce a certain sound when it is working because of the rotation of the fan and the flow of air.

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 contact the official after-sales service for testing.

The reasons for the flurry of laptop sounds are as follows:

It may be caused by the fan being out of the factory for too long and the lubricant drying up;

It may be caused by the poor stability of the fan power coil, which causes the coil to heat up due to long-term rotation and drying the lubricant;

That is, there is too much dust adsorbed on the fan blades, which produces eccentric force, and the uneven rotation of the fan blades causes swing and will also make large noise;

The noisy laptop fan is also related to the structure of the fan:

1).The structure of the fan of a high-end business laptop is magnetically levitated. There is almost no noise.

2).In order to save costs, general notebooks do not use fans with magnetic levitation structure. Instead, a fan with a shaft core is used. This can happen at higher speeds or when there is dust on the fan blades. Creates an eccentric force swing. Cause a shock. Make loud noises.

The chassis is of poor quality. Manufacturers in order to save costs. The iron used is thin. It is also easy to resonate with hardware vibration. Amplify noise. Creates a buzzing sound.

The computer is overheating, indicating that the computer needs to take a break.

Therefore, there will be a burst of sound on the computer, and the advice given for this is: if the sound is very serious, the computer needs to be cleaned and checked.

It may be that there is a problem with the internal system of the computer, and it is good to make the system, or it may be caused by dust entering the computer, so clean it up and try it.

Maybe it's about to break, that's why it's like this, it's about to break, that's why it keeps making this sound. I'm going to take it, bring it and take a look.

Computer Buzzing Reason:

1. Feel the temperature of the computer outlet with your hands. If the high temperature continues, there may be a large number of programs running in the background of the computer, causing the CPU to run at high speeds and generate high heat. Fans must maintain a high wind speed to achieve heat dissipation.

2. The cooling fan is damaged, and the fan will gradually wear out after long-term use, or because the bearing lacks oil, resulting in loud noise when the fan rotates. Moreover, due to the low accuracy of the workmanship of inferior fans, the deviation of the center of gravity of the fan blades will cause the fan to be abnormal.

3. After the computer is used for a long time, a large amount of dust will accumulate on the fan blades, which will increase the fan load and reduce the speed. In order to achieve the standard airflow, the fan will rotate at a higher speed, causing the fan to be abnormal.

How to solve the loud noise of the computer host:

1. We can observe the internal situation of the computer host, see if there is dust stuck in the fan, and use a brush or hair dryer to clean up the dust inside the computer and the dust in the hardware fan.

2. If the noise of the CPU radiator is still very loud after dust removal, you can directly replace it. CPU coolers are cheap, dozens of dollars for one. At the same time, the case fan and graphics card fan can also be replaced.

3. There is a sizzling sound when the mechanical hard disk is read and written, indicating that there is a problem inside the mechanical hard disk. This is irreparable. If there is a warranty, you can go to the after-sales service for a replacement. If you don't have a warranty, you'll need to replace it with a new HDD or SSD.

The reasons for the loud buzzing of your laptop are as follows:

1. Power supply fan. If the computer will have a buzzing sound when it is turned on, you may wish to turn off the computer first, and then use a screwdriver or pencil to insert it into the vent of the power supply fan in the shutdown state, and then turn it on after holding the fan, if the hum still exists, it proves that there is no problem with the power supply fan, and if the hum disappears, it proves that it is caused by the problem of the power supply fan (it should be noted that when shutting down or booting up the test, the time should not be too long, and after testing the fan sound, you should immediately pull out the screwdriver or pencil-shaped object).

In this case, it is best to find a computer company to help replace it, because you need to disassemble the power supply, and then cut the fan line, and connect the external power supply additionally.

2. Motherboard fan. There are two kinds of motherboard (CPU) fans, one is AMD's, AMD's can be held down with your fingers, but if it is an Intel fan, you must use a screwdriver or pencil-like object to pin the fan in the shutdown state, and then turn it on, if the sound is still there, the problem of the motherboard fan is ruled out, if the sound disappears, it proves that it is a problem with the motherboard (CPU) fan, you can directly buy a universal fan to replace it, if the user will not replace it, you can go directly to the computer company to replace it. 3. Graphics card fan.

The three most common fans in a computer case are the power supply fan, the motherboard (CPU) fan, and the graphics card fan.
