Why is my laptop so loud? How can I make my computer fan quieter?

You have to analyze why the laptop is too loud, some laptops may have a power supply fan that is too loud, some laptops have a graphics card fan that is too loud, and some laptops will have hardware problems.

In most cases, when we use laptops, most laptops don't make any sound because the system is better optimized. So we're making large images, or we're playing big games, and most notebooks can support the basic functions of the user. When the laptop is too loud, this phenomenon will not only affect the normal use of the user, but also may cause harm to the closed-door computer.

1. What is the reason why the laptop is too loud?

There are three main cases when the laptop is too loud, the first case is that the fan of the power supply is too loud, the second case is that the fan of the graphics card is too loud, and the third case is that the laptop has bad sectors or damage. When you hear that the laptop is too loud, you can try to touch the back panel of the laptop and feel the exact location of the laptop that is too loud. <>

2. The sound of the power supply and graphics card is too loud, and it can be dealt with directly by replacing the fan.

If the power supply of the laptop is too loud, you should check whether the fan of the power supply is clogged with dust, and if so, you can try to brush off the dust directly with cat litter. If this method does not solve the problem, you can try to take the computer to the after-sales office for fan replacement. If it's because the fan of the graphics card is too loud, you should be careful not to overload the graphics card when using the computer, and it is best to control the temperature of the graphics card within 50 degrees, so that you can significantly reduce the fan sound of the graphics card.

3. The problem of computer hardware needs to be replaced directly.

Because many accessories of the laptop cannot be disassembled directly, let alone assembled by yourself, if it is because of the hardware problem of the computer, I recommend that you take the laptop directly to the after-sales office for replacement. During the warranty period, you will be able to receive the recommended replacement service directly. <>

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.

It may be due to a malfunction in the laptop, if you want the fan to be quieter, you can raise the laptop slightly.

This situation is usually caused by the aging of the cooling fan, and only need to replace the fan with a new one can solve the problem.

This situation is caused by the excessive accumulation of dust by the cooling fan, so you only need to remove it to clean it up and put it back on.

How to make the laptop's fan quieter:

1.Start by opening the Control Panel, open "Power Options".

2.Click "Change plan settings".

3.Click on "Change Advanced Power Settings".

4.Click on the + sign before "Processor Power Management".

5.The heat dissipation mode of the system is changed to "passive".

6.The maximum processor state is changed to a smaller point, before the opening is 100%, you can try to change it to % or lower, then you will find that your laptop will no longer have a sudden fan speed increase and then decrease the phenomenon, it will rotate at a lower speed at a uniform speed, it is not so noisy, in fact, it essentially reduces the maximum frequency of the CPU turbo frequency, reducing the heat generation of the CPU.

<>1. Use a Phillips screwdriver to loosen the screws on the cover plate corresponding to the laptop fan, the screws may not be able to be removed, just turn to a very loose one.

2. Use a flathead screwdriver to pry open the side of the fan corresponding to the width of the cover plate, and the bucket can be divided into three points: upper, middle and lower to pry step by step.

3. After prying loose the cover, lift the cover, and use a needle or a small screwdriver to clean the dust on the dust-proof vent on the wax cover until it is cleaned up and each small hole is transparent and the light is visible.

4. Remove the CPU fan, scrape off the dust on the fan blades and fan shaft with a flathead screwdriver and needle, tap the fan to make the dust fall, scrape and combine until the fan is clean and dust-free.

5. Install the fan back, cover the cover plate, test the wax flushing and slip to try to start the big software, and see if the fan sound has become smaller.

6. If you still think that the fan sound is still not as small as when you bought it newly, you can remove the fan and go to a computer store or buy the same model fan online to replace it.

1. Dust removal: Generally speaking, the newly purchased fan is always less noisy and sleepy, 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 period 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 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, a 1 2 mm thick soft gasket (such as leather and rubber) is added between the four corners of the fan and the contact surface of the heat sink to effectively reduce the noise caused by the vibration of the fan and the heat sink.

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.

Setting up your computer's cooling fan typically requires the following steps:

Confirm the connection of the cooling fan: Check that the cooling fan is properly connected to the cooling fan slot on the motherboard. Make sure the connection is secure and the plug is not loose.

Enter BIOS settings: Restart the computer and press the corresponding Yanqiao cavity button (usually DEL, F2 or F10) during the boot process to enter the BIOS settings interface.

Look for fan control options: In the BIOS settings screen, look for options related to cooling fans. These options may be labeled as "fan control", "hardware monitor", or something similar.

Adjust the fan speed: In the fan control options, you can usually select a different fan speed mode, such as "Auto" or "Manual". If you choose manual mode, you can set the speed or percentage of the fan on the shirt.

Adjust the fan speed to suit your cooling needs and personal preferences.

Save Settings and Exit: After you are done setting up the fan, make sure to save the changes and exit the BIOS settings. You can usually follow the on-screen instructions to save your settings and then erase your new startup computer.
