What s going on with the sudden louder sound of a laptop fan?

The sudden louder sound of the laptop fan is due to the high internal temperature of the laptop, which triggers the high-temperature cooling mechanism, which causes the fan to become louder. If the fan is running at high speed for a long time, please pay attention to the following 3 points:

Whether the air outlet of the radiator is blocked by dust, if it is blocked, please disassemble the machine to clean the ash. (If you don't have the ability to do it, please send it to a professional maintenance point for cleaning).

Check whether the heat dissipation cinnamon sticks on the CPU and graphics card are dry and invalid, please replace them with new hot silicone grease.

Check whether the system is loaded with too many useless processes, resulting in high CPU usage and heating. Please remove the redundant software to clean up the system junk.

1. The computer has been used continuously for a long time, the machine is soupy, and the fan has been running for a long time to cause the sound to become louder, shut down for 10 minutes and wait for the computer to cool down and then restart;

2. The computer has been used for a long time and has not been cleaned, so it is recommended to send it to the computer market to spend 50 yuan to clean the ash, and there are about 20 pieces, and the dust will also cause the fan to become louder;

3. If there is a problem with the fan, you can change the fan.

The laptop fan is controlled by a temperature control chip, when the temperature rises, the fan automatically rotates, it will make a little noise, when the temperature drops, it will not rotate, your situation is normal, as long as the sound is not harsh, it is OK

It should be normal.

The fans of laptops are not the same as those of desktops.

It's not going to turn fast all the time.

In order to save electricity. He adjusts himself according to the temperature inside the plane.

When it's too hot, he suddenly becomes happier.

It's going to be louder.

If this continues, change it as soon as possible! It's usually just a few minutes when it's louder.

I looked at the supplement. Yes, how can there be dust in the one I just bought, or the sentence above.

Added again? You say it's normal in a while? That's normal, there's no need to change it, I have two notebooks in my bedroom, it's the same, it's okay!

Because the computer is too hot, it needs to dissipate heat, and the fan is overloaded.

Most of the reasons and solutions for laptop hot are as follows:

1. The laptop is too dusty, it is recommended to disassemble the computer and clean up the dust to prevent the CPU temperature from being too high because it cannot dissipate heat;

2. Check whether the fan is damaged, and if it is damaged, replace it with a new fan in time;

3. The silicone grease on the CPU has been completely baked, and it is recommended to reapply the silicone grease to assist the CPU in heat dissipation;

4. Install the driver software, the driver is very important, and the driver can adjust the hardware operation state according to the use case, so as to reduce the power consumption and reduce the heat generation.

China Pure Graphene Powder Product Release Notebook Faster Heat Dissipation:

In recent years, the academic and application development of graphene at home and abroad has continued. From an application point of view, graphene can be divided into two forms: graphene powder and graphene film.

The Chongqing Institute of Green and Intelligent Technology of the Chinese Academy of Sciences has developed a 15-inch single-layer graphene with a light transmittance of 98, which is mainly used in touch screens. Graphene films are expected to be a key material for the next generation of flexible electronics. Graphene is expected to make new materials and devices thinner, lighter, stronger, and more flexible, and has broad application prospects.

Wang Gongkai introduced that by preparing a high-concentration non-agglomerated graphene solution, a layered structure of graphene microsheets with good orientation is formed, and then reduced under a specific chemical atmosphere at high temperature.

The edge grains of graphene microsheets grow and finally expand into a large-area continuous two-dimensional structure of graphene flexible heat dissipation films. The film products produced by this method were confirmed to be the first in China by the Ministry of Science and Technology of China in March 2013.

Could it be DNF itself, mine too, other games don't have sound, just DNF.

Method 2: Clean up the dust when there is too much dust.

Method 3: The position of the fixing screw is shifted due to loosening, and the screw needs to be re-fixed.

There are several reasons why a computer fan suddenly becomes louder:

Too high temperature: Computers generate heat when they are running, and if the heat dissipation is poor, it can cause the temperature to be too high, causing the fan to spin faster and make loud noise.

Fan failure: After a long period of use, the computer fan may malfunction, such as the wear of the shaft sail shed, the deformation of the blades, etc., which will cause the fan to make loud noise.

Dust clogging: After the computer is used for a long time, a large amount of dust and dirt will accumulate, which will clog the fan and radiator, resulting in poor heat in the scattered state, which will make the fan spin faster and make loud noise.

If the computer fan suddenly becomes louder, you can troubleshoot it according to the specific situation. You can first clean the dust and dirt inside the computer and check whether the fan is working properly. If the fan fails, the fan needs to be replaced.

If the temperature is too high, you can add a radiator or replace it with a more efficient radiator. If you are not familiar with the maintenance operation, it is recommended to seek professional maintenance personnel for repair.

There are a number of reasons why a computer fan suddenly becomes louder, and here are the possible causes and ways to solve the imitation date:

High temperature: When the temperature of the CPU or other hardware is abnormally high, the computer fan may automatically increase the air speed to cool down the heat. You can use monitoring software such as hwmonitor, speedfan, etc. to see if the hardware temperature is too high, if so, try to remove dust and debris from your computer's radiator, or replace it with a more efficient radiator.

Damaged fans: Computer fans may malfunction due to prolonged use or other reasons. If the blades, bearings, or motor of a computer fan are damaged, the sound may become unusually loud. At this point, it is recommended to replace the computer fan.

Busy applications: Some applications require large amounts of computing resources, which can cause heavy load on the CPU and other hardware. When your computer is under stress, the fan may speed up.

You can use Task Manager to see how much computing resources are being used by applications, close unnecessary programs, or rebase your computer from starting up.

Stuck programs: Some programs may be abnormal or stuck, causing the CPU and other hardware to be at full load for a long time, and the fan operation to be accelerated. Try closing the program that is already stuck or restarting your computer.

It is important to note that a noisy computer fan may be a problem with the computer hardware, so make sure to back up important data and operate cautiously to avoid further damage before adjusting the fan or other hardware. If you are unsure about the cause of the problem and how to proceed, it is advisable to seek professional help.

The sudden loudness of the computer fan may be due to one of the following reasons:

1.The computer is overloaded, resulting in an increase in the temperature of hardware such as CPUs and graphics cards, and the increase in hardware temperature will naturally increase the fan penetration and dismantling Zen, so the sound will become louder.

2.The fan is blocked by dust, which can also be understood as the fan is "short of oil".

3.The aging of the silica gel will not be able to transfer heat well to the heat dissipation copper sheet, resulting in the fan running quickly to dissipate heat.

1. The computer is not flat: there are generally two fans in the laptop, namely the CPU fan and the graphics card fan, if it is used normally, the fan emits a "whirring" wind sound, if the laptop is placed in an unstable or uneven position, it will cause the fan to not be in a relatively flat position, and there will be a "buzzing" sound when running. Workaround:

In this case, you can turn off the computer first, then flip the computer, and then reposition it to turn it on, and the sound will disappear.

2. Different fan modes or too many opening programs: Some laptop fans can adjust the speed, the fan has a service life, and when the wear is serious, if the standard or boost mode is turned on, there will be a "buzzing" sound. In addition, opening too many applications at the same time will also cause the CPU to run faster, and the fan operation pressure will be high.

Solution: Take ASUS laptops as an example, you can press the "FN+F5" key to switch the fan to liquid dispersion speed, and the hum will disappear. In addition, the application of the redundant base chain is closed to reduce the CPU usage.

3. The computer fan has a lot of dust or the fan bearing is damaged by lack of oil; If there is a lot of dust on the computer fan after using it for a long time, in order to achieve the air supply volume, the fan will rotate faster and there will be a sound. It is also possible that the noise that occurs is caused by the CPU cooling fan getting stuck or the oil drying out in the fan bearings.

Solution: Open the back cover panel of the notebook, remove the cooling fan of the CPU, and sweep away the dust on it with a brush.

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.

Reasons why the fan is 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.

Loud Solution:

1. Dust removal, generally speaking, the newly bought fan is always less noisy, and it will become significantly larger 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.

2. Add lubricating oil, for oil-impregnated bearing fans, it is common for the motor drive shaft to become inflexible after a long time of work. 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.

3. Reduce vibration, 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 generated 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.

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.
