The laptop fan is loud and vibrates loudly, but what are the effects of normal heat dissipation

Many of my friends have complained that their computers are too noisy. In fact, the biggest culprit is the CPU fan. Generally speaking, newly purchased fans are always less noisy, and they become significantly louder after a period of use.

In fact, dust is one of the main causes of fan noise, because pervasive dust can always penetrate into a chassis that is not completely sealed. When the CPU fan spins at high speeds, the vortex effect makes it easy for dust to adhere to the fan. There is no doubt that it is necessary to remove the CPU fan and clean it properly at this time, and when removing dust, everyone should pay attention to the gap between the back of the fan and the heat sink, which is the easiest to forget.

For fans with oil-impregnated bearings, it is not uncommon for the motor shaft to become inflexible after a long period of operation. For this reason, it is recommended that you add lubricating oil to this location, and it is recommended to use mechanical lubricants or gasoline engine oil. Of course, care must be taken when adding lubricating oil and never allow it to spill.

In addition, the vibration problem also needs our attention, usually the high-speed rotating fan will have a high-frequency collision with the heat sink, if the fan and the heat sink are stable and appropriate, the vibration and noise caused by the collision can be greatly reduced. For example, holding a CPU fan that spins at high speed in your hand is much less noisy than holding it to a heatsink because the soft human hand absorbs a lot of vibration. According to this principle, adding a 1 2 mm thick soft gasket (such as leather and rubber) between the four corners of the fan and the contact surface of the heatsink can effectively reduce the noise caused by the vibration of the fan and the heatsink.

In the summer, many users choose to stop overclocking, and at this time, high-power fans are obviously unnecessary. The main reason why the fan is too loud is its extremely high speed. If we reduce the speed of the fan, then the noise problem will be further alleviated.

In fact, even if the CPU fan we use can't adjust the speed, we can make up for it with a dedicated fan governor. The Fanmate1 fan governor launched by Zalman is very popular in the domestic market, and Kyushu Fengshen also has a similar product. The use of this kind of fan governor is very simple, you only need to plug the power connector of the CPU fan into the fan governor, and then connect the fan governor to the CPU fan power connector on the motherboard.

Mine too, it only appeared in the last few days, and it was suddenly loud and vibrating, and it was only after the dust was removed, the heat dissipation and the experiment were normal, and it was likely that the fan was aging, and there was friction in the shaft or something. Usually I play a lot of games, and the fan keeps spinning at high speed, and I only got the fan after a few days, and I'll watch it when the time comes. The maintenance department told me that it was fine, but of course, I couldn't take all their words seriously.

It's better to change the fan. It's not good for the computer to keep shaking.

It's best to overhaul it to see if the screws are loose or the fan is not good, so that a small problem does not become a big problem.

What should I do if the college entrance examination score is different? Reread???

The solution to the loud sound of the laptop cooling fan is as follows:

1. The sound of the computer fan is loud, as long as the heat wave of the air outlet is rolling, it means that the CPU is hot, not that the heat dissipation is not good, but that the CPU itself is overheated and hungry, you can add a laptop base to dissipate heat, especially in summer.

2. Some old notebooks, the fan is aging and lacks oil, and the noise is high, so you can replace the fan, but refueling has no effect. When changing the fan, blow clean the dust, and replace the CPU and graphics card heat dissipation grease by the way, and use silver silicone grease.

3. System and software problems, most of them are sins created by win10, running hundreds of processes at the same time, and the CPU can play up to 25% without doing anything. Use 360 to clean up the system garbage, close all self-starting programs that can be closed, and be ruthless.

Reasons why the laptop is stuck

1. Insufficient CPU.

When the CPU usage is too high, the computer will lag, you can turn off the redundant process, or replace the CPU with good performance to solve this problem.

2. Insufficient memory.

Insufficient memory will affect the running speed of the program, causing the computer to freeze or crash, you can clean up the programs and temporary files running the memory, and you can also change a large memory module or place an extra memory module to solve the problem.

3. Poor heat dissipation.

Poor heat dissipation of the computer will also lead to unsmooth lag, so you can replace the heatsink or related hardware to improve the heat dissipation capacity.

4. Poisoning. If the computer is also poisoned, it will also cause lag and fluency, you can use antivirus software to disinfect the virus, or reinstall a system to solve the problem.

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 ambient temperature is higher than that of the user, too many running programs or large software will cause the CPU temperature to rise, when the CPU temperature increases, the fan will rotate frequently and crack a little more, and the sound will be a little louder. If the sound is particularly loud or abnormal, it is recommended that you go to the nearest ASUS official service center to check and confirm, and it is better to have an ASUS engineer test it on site.

Analysis of the reasons why laptop fans are loud:

1. If the use time is too long, the coil of the fan is aging and there is a lack of oil.

2. Due to improper use, the central shaft is bent due to impact or vibration.

3. The position of the fan is offset due to excessive dust accumulation or loose fixing screws.

4. Power supply problem.

2. Tighten the screws that fix the computer fan to avoid the computer fan from loosening, resulting in loud sound in the case;

3. Regularly deal with the dust accumulated in the chassis, especially the dust on the computer fan, which must be cleaned up.

4. Disassemble it yourself, simply put, first pry open the place with the interface on the top of the keyboard, and then disassemble all the screws underneath, first take off the keyboard, then take off the optical drive from the rear, take off the hard disk, you can disassemble it and see the cooling fan, you will know what the problem is.

5. It is not a big problem that the fan is broken, if you change the fan, it depends on the specific model, the fan is short of oil. Go to after-sales within the warranty, and buy sewing machine oil outside the warranty.

How to solve the noisy computer fan:

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 an aging and low-level computer configuration, then you can solve the problem by upgrading the computer system configuration.

Screen Saver:

1. When the computer is not used for a long time, the function keys on the keyboard can be used to temporarily turn off the power of the LCD screen, which can not only save power but also prolong the life of the screen.

2. Do not force the lid of the LCD screen or place any foreign objects between the keyboard and the display screen to avoid damage to the internal components caused by heavy pressure on the upper glass.

3. Try not to touch the surface of the screen with fingernails and sharp objects (hard objects) to avoid scratches.

There are many reasons why the laptop is loud for heat dissipation, it may be that the computer has the performance mode turned on, and on some gaming laptops, it has a performance mode, which can be turned off when not playing games; It may be that the computer fan is damaged, it is recommended to contact the after-sales service; It may be caused by dust ingress from the fan and needs to be cleaned regularly.

2. The laptop has a mobile hotspot function, you can turn on the hotspot for the mobile phone, if you need to use it, turn on the computer, enter the settings page of win10, click on the network and Internet, and then find the mobile hotspot, select the mobile hotspot, and turn on the function to use.

3. The laptop can change the system language, turn on the computer, enter the settings page of win10, click on the time and language, select the language, and then find the display language option, set the language you need to use, and you can also modify the date and time.

Data expansion: On October 1, 2014, Microsoft Zhongkai held a new product launch conference in San Francisco, showing a new generation of Windows operating system, naming it "Windows10", and the name of the new system skipped the number "9".

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 crack and disturbance. The rotation of the fan is related to the temperature of the CPU, such as the ambient temperature is high, too many running programs or large software will cause the phenomenon of slow CPU temperature increase, when the CPU temperature increases, the fan will rotate more frequently, and the sound will be a little 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.
