Is the laptop fan suddenly turning on loud 30

The fan is loud when the laptop is turned on:

1.After using it for too long, the coil of the fan is aging and lacks oil.

2.The bottom bracket is bent due to improper use, impact or vibration.

3.Excessive fan dust accumulation or loose set screws cause the position to shift.

4.Power supply issues.

Here's how to fix it:

Disassemble it yourself, first pry open the place with the interface on the top of the keyboard, then disassemble all the screws at the bottom, take off the keyboard first, and 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. If the machine is on for two years, it is the fan with dust. If the new machine can't be the machine, the heat will be large, the fan is with the temperature of the machine, the sound should be the sound of the hard disk, and the professional maintenance of the notebook.

There is nothing sudden that the launch is not sudden, or someone announces a prepared launch. Just start the fan is relatively loud.

Generally speaking, when your computer occupies high memory, CPU, and graphics card, the computer fan will turn faster and the sound will be louder! Normally, the fan doesn't make a lot of noise! Unless there's something wrong with the fan!

If it has been a very loud turn, you need to check whether the cooling fan needs to be cleaned and dusted.

Summary. 1. It is because the hardware temperature of the computer is too high, which causes the automatic protection function of the computer to start and automatically shut down to protect the computer hardware from burning.

2. When the computer is turned on, with the extension of the running time, the accumulation temperature of the hardware is getting higher and higher, and the cooling fan is automatically accelerated, trying to cool down the high-temperature hardware.

3. The occurrence of such computer automatic protection phenomenon is mostly caused by excessive dust accumulation in the fan radiator, or the heat sink is not installed in place, and the heat dissipation grease is dried up and fails.

The laptop fan suddenly gets louder and then shuts down.

1. It is because the hardware temperature of the computer is too high, which causes the automatic protection function of the computer to start, and the automatic shutdown to achieve this silver to protect the computer hardware from burning. 2. When the computer is turned on, with the extension of the running time, the accumulation temperature of the hardware is getting higher and higher, and the cooling fan will automatically increase the pure stupid speed, and strive to cool down the high-temperature hardware. 3. The occurrence of such a computer automatic protection phenomenon is mostly caused by too much dust accumulation of the fan to accompany the radiator, or the radiator is not installed in place, and the heat dissipation silicone grease is dried and fails.

1. Open the computer cover, remove the cooling fan, and use a brush to clean up the dust on the fan and radiator. 2. You can add lubricating oil to the fan shaft, check whether the installation of the heat dissipation cluster is tight, and whether the heat dissipation silicone grease needs to be replaced. 3. After everything is processed, install it as it is, and then start it up.

You can use the software to check the temperature of the computer hardware after turning it on, and if it is still very high, you can consider replacing it with a better fan radiator.

Okay, thank you.

The computer is turned on and the fan turns off after a few minutes.

The reason for heat dissipation may be that the pre-key is large, it may be that the heat dissipation system is inefficient due to excessive dust accumulation or the aging of thermal grease, or the level of the heat dissipation system itself is very low, and it is difficult to suppress the temperature of the CPU running at full load, which will lead to excessive CPU temperature sensitivity, and finally exceed the power-off protection temperature (generally around 104°C), resulting in automatic power-off and shutdown. It may also be that the current is too high, and it is recommended to try a different socket.

1. When the machine is turned on, the fan is running at full speed, so the sound will be loud, but when it is running normally, the speed will slow down and the sound will be soft. Because the current motherboard is BIOS automatic control.

Automatically adjusts the fan speed according to the temperature.

2. When the system is just started, the temperature and other related data are not obtained, so the fan is running at the maximum speed (no speed limit), and the BIOS system detects the fan speed, and after the current motherboard temperature, the fan will be automatically adjusted, and the speed of the fan will slow down, if the temperature is high, the fan will automatically speed up.

3. It can be seen from the interface of the fan that the system has a control line for speed monitoring and speed adjustment.

4. It is also possible that the fan has been used for a long time, which is caused by dirt and excessive dust, and the operation is not effective, and lubricating oil needs to be added.

This answer applies to most computer models such as the Dell Vostro 3668.

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.

The reason why the fan is loud after the laptop is turned on is generally because it has been used for too long, the coil of the fan is aging, and there is a lack of oil. It can also be due to improper use, impact or vibration that causes the bottom shaft to bend.

The solution to the loud fan after the laptop is turned on is as follows: first pry open the place with the interface on the top of the keyboard, then disassemble all the screws at the bottom, take off the keyboard first, then take off the optical drive from the rear, take off the hard disk, you can disassemble it to see the cooling fan, and clean the hot fan.

1.After using it for too long, the coil of the fan is aging and lacks oil.

2.The bottom bracket is bent due to improper use, impact or vibration.

3.Excessive fan dust accumulation or loose set screws cause the position to shift.

4.Power supply issues.
