Laptop CPU fans sometimes have a lot of noise, let s do it 30

Loud noise in the rear case: The parts of the case that cause the most noise are the fans, such as the cooling fans of the power supply, and the cooling fans of the CPU, graphics card, and motherboard chips. Open the case, start the computer to check, and find that it is the noise from the CPU cooling fan.

Clean up the dust on the fan blades of the cooling fan after shutting down, and the fault will still be there after powering on. Turn it off, remove the fan, drip some lubricating oil into the bearing section, troubleshooting.

Adding a 1 2 mm thick soft gasket (such as leather, 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.

How do you add oil to a fan?

The method is to dust the stator and rotor of the fan first, and then clean it. The method of cleaning the rotor is to remove the "O" shaped small rubber ring at the root of the shaft, and clean it with anhydrous alcohol, and then submerge the rotor in the alcohol and scrub it with absorbent cotton and take it out, put it into the "O" shaped rubber ring, and put it aside to dry and set aside. After that, the stator is cleaned again.

When washing the stator, it is necessary to pay attention to not let the coil come into contact with alcohol, otherwise the paint film on the surface of the coil will be dissolved, causing damage to the coil. The method is to wrap a very small amount of absorbent cotton around a toothpick, dip it in alcohol and stuff it into the copper sleeve of the stator, and rub it repeatedly until it is clean. After the alcohol is evaporated, two drops of engine oil are dropped in the copper shaft sleeve, and one drop is also dropped on the rotor shaft, not too much.

Finally, it was packed as it was.

can be exchanged, a matter of dozens of dollars.

If it is within the warranty period, it is best to take it for repair.

The noise may be due to the fact that the fan is not installed securely.

Go fix it and take a look.

The fan is not installed firmly and is prone to noise.

Maybe it's too much dust, you can take it apart and clean it up, and if you're not sure, don't do it yourself.

Actually, you don't have to be afraid of doing it lightly, and if you think it can't be done, just put it all back. How can you understand without trying?

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.

Laptop fan loud solution:

1. Remove dust.

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.

2. Add lubricating oil.

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.

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, 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.

The temperature is high and the fan is loud.

This kind of fault is mostly because the fan is dirty or damaged, and it is mostly dirty, and it will be okay to send it for repair and dismantling, and if it doesn't work, you need to replace the fan.

I'll help you in Beijing.

If you are not in Beijing, it is recommended that you find a reputable and skilled repairer to help you overhaul.

We are here to clear once is 40 yuan, the noise is necessary to be related to the dust and oil, the dust on the fan blade is not good, the CPU temperature is too high, and the fan speed is accelerated. It's going to be loud. It is necessary for you to clean the dust. My home in Jilin.

The situation of the fan in front of my notebook is the same as yours, suddenly it is very loud, you have used this for 2 years, the fan should be cleaned up, there must be a lot of dust accumulated in it, which will affect the heat dissipation, and the poor use of the CPU and graphics card of the notebook will greatly affect the life and efficiency, or if you do not clean the fan for a long time, the fan will lack oil, resulting in the aging of the fan's hinge, resulting in the fan breaking. You'd better clean it up, if you're good at doing it yourself, you can disassemble it yourself and clean it up, when you want to be careful and bold, but don't worry about it, go to a good quality and reputable maintenance point to do, we are cleaning up the oil 30rmb, if you send it to clean up, you can stare at the point there, awareness insurance and you can also learn it, and you can do it yourself in the future.

Generally, when the machine is turned on, the fan basically rotates at the highest speed, if the sound is particularly loud or special, it is best to go to the after-sales service to disassemble and clean up the dust or put on some lubricating oil, it is free to clean up during the warranty period, after the warranty period, my thinkpad is only 10 yuan to clean up once, in Shijiazhuang.

You said that something seems to be stuck there, suddenly quiet, or take it to the after-sales service to open it, if you do it yourself, you can open it yourself and clean it up, and it will not affect the warranty if you open it yourself.

The noisy fan is due to the current high heat dissipation pressure of the computer, and the heat dissipation conditions should be improved.

Heat dissipation can be improved in the following ways:

1. Keep the bottom transparent, and the heat is not easy to accumulate.

2. The keyboard membrane should be used with caution, and the display screen should be always on.

3. Make good use of power management to achieve the purpose of heat dissipation.

4. Pay attention to regular ash cleaning.

5. Use an exhaust radiator or heat dissipation base when necessary.

It is possible that your laptop has not been cleaned for a long time, and there is too much dust in the area, which affects the heat dissipation of the fan.

The laptop fan is generally turned on and turned around, stopped after a while, and then turned after it was hot, and the sound was generally dirty inside, and it needed to be cleaned, maybe there was dust or something stuck in the fan.

1. If it is a problem with the fan, you can disassemble it for cleaning or replace it (you can't go to the after-sales service).

2 It may also be just a problem with the operation of the computer, my notebook sometimes will, such as when starting a program or opening too many web pages, the sound is very clear, sometimes it is good not to pay attention to it for a while, I don't know if what you said is so.

3There is also a possibility that there are too many boot items, and the computer performance is average, or it may be, do you take a long time to boot? If it's a long one, you can try to delete some unnecessary boot items.

That's probably the fan's business,The reason why it will be quiet is because,When the temperature of the CPU is not high,The fan of the notebook will not rotate,If it is during the warranty period, you can take it to the warranty,If you can't open the back cover by yourself to clean up the dust on the fan,If you have strong hands-on ability, you can add some lubricating oil to the rotor of the fan,(If there is no lubricating oil, you can replace it with sesame oil,Rapeseed oil),Turn the impurities inside out along the oil,Then wipe it clean,Remember to ensure that it is clean when you install it。 It is also possible that the fan blades are deformed, in which case you have to change the fan, just buy one according to the model and install it yourself.
