The boot fan is very loud, and it will be fine after 5 or 10 minutes Want to change the fan, is it s

There are all kinds of fans, yours is the original with a fan, you said that if you buy a loose fan, the fan will not be alive, and the point will not be lit. You go to the electronics market fan counter there are all kinds of them. But I advise you not to buy it anyway.

Solder some oil handles yourself. It's not a difficult thing, you want to change the fan, what did you do when you bought a box, but you have money and nowhere to spend it? You use a screwdriver to unscrew the fan from the heatsink, and you will see the plastic logo on the fan's back, and remove him as well.

I saw the fan, and the wind carried it. Solder joint oil, turn the fan. I put a plastic logo on it.

The fan goes up to the heatsink. Everything is ok. It can't be broken, it's not as precious as you think.

Eldest brother. Your hometown is so nice. It's fine for two years. My home in Shenyang. Dusty. The original fan for five months is like a tractor.

Later, I spent 70 oceans to buy a Martian TT Silent King. It's cool. It's been a year and a half. Still can't hear anything.

There are downsides, though. Always worry about the fan stalling >

AMD also uses a dedicated silent fan. But you get what you pay for. You look at it and buy it. The js guys will recommend a good one for you.

There are some that are sold, and you can also try oiling yourself, but pay attention to the seal.

There was a lack of oil in it.

Just buy one, and it's not that much.

It's up to you which CPU has a cheap one, it's not necessary to be too expensive.

Just use a foxcon or a Jiuzhou Fengshen's.

It doesn't matter if it's silent or not, when you use it, you'll find that it's almost the same.

Yes, it is sold at a local compatible phone store.

Summary. Hello, the reason why the fan is turning is because: 1. Bearing wear:

With the passage of time in the use of electric fans, the loss of its individual components will also increase correspondingly, and the loss of bearings is the most obvious. When the bearing is out of fit due to wear and tear, it will make a noise due to axial runout. 2. There are debris in the gap between the stator and rotor

Due to long-term use, all parts of the electric fan are prone to dust deposits. If there is debris in the gap between the stator and rotor, it will cause a frictional sound caused by the barrier during rotation. 3. Deformation of fan blades:

Plastic blades can be deformed to varying degrees depending on the time of use, so this is also the source of the noise.

Hello, the reason why the fan is rotating is because: 1. Bearing wear: With the passage of time in the use of the electric fan, the loss of its components will increase accordingly, among which the loss of the bearing is the most obvious.

When the bearing is out of fit due to wear and tear, it will make a noise due to axial runout. 2. There are debris in the stator and rotor gap: due to long-term use, all parts of the electric fan are easy to deposit dust.

If there is debris in the gap between the stator and rotor, it will cause a frictional sound caused by the barrier during rotation. 3. Deformation of fan blades: plastic fan blades will be deformed to varying degrees due to the time of use, so this is also the source of the sound.

4. The grille is not tightly fixed: when the fan is running, the grille is not fixed, and there will be vibration, which will make a sound. 5. The axial movement of the motor is too large

The axial sliding clearance of the fan motor shaft is generally less than 1 mm, and it is abnormal if it is too large, and there is a section between the rotor and the bearing that is controlled by a positioning sleeve, which may be damaged by the sleeve at high temperature.

Hello, it's also possible that your fan blades are not properly installed (not fixed in place) or the balance tabs on the blades are off.

Extended Information: The Principle of Fan Rotation:1

The main component of the electric fan is: AC motor. Here's how it works:

The energized coil rotates by force in a magnetic field. Electrical energy is converted into mechanical energy, and at the same time, due to the resistance of the coil, it is inevitable that some of the electrical energy will be converted into thermal energy.

You can take a look on the Internet.

My t42 online fan is 80

Later, I repaired it myself.

About 100 or so, but I don't know what brand you are, and it doesn't necessarily cost muchIf it is sent to Lenovo's repair shop, the price should be no less than 20 yuan.

How long has it been used? As long as it's not very loud and a little buzzing, it's normal.

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 compensate for it with a dedicated fan governor (Figure 2). The Fan Mate1 fan governor launched by Zalman is very popular in the domestic market, and Kyushu Fengshen also has similar products. 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.

As for users with strong hands-on ability, you can try the method of connecting resistors in series to reduce the working voltage. As for the resistance value used, you can use the nameplate on the CPU fan to calculate it (remember p=ui, r=u i is enough), and at this point we can get any voltage. Finally, we would like to remind everyone that after reducing the CPU fan speed, be sure to turn on the corresponding temperature monitoring function in the BIOS to ensure safety.

Of course, at this time, you can set the alarm temperature and shutdown temperature higher.

Normally, it works at the maximum speed when it starts, so the sound is loud.

Summary. Hello dear, there are many reasons for the squeaky shaking head of the electric fan, it may be that the product itself has a quality problem and needs to be returned; It may be that the equipment has been used for a long time, resulting in insufficient lubrication of the rotating shaft, and lubricating oil needs to be added to solve the problem; It may be that the equipment-related parts are seriously worn and need to be replaced. Precautions for the use of the equipment:

1. When the electric fan is carried, it can be disassembled and carried for easy movement, and all the connecting wires need to be unplugged before moving the electric fan. 2. The electric fan needs to be used on a flat ground to avoid noise, and do not place heavy objects above the equipment, which may cause the deformation of the equipment shell. 3. The electric fan needs to be cleaned regularly, and do not wipe it with corrosive liquid, which will cause the deformation of the equipment shell.

4. Do not disassemble and assemble the electric fan by yourself, and need to be maintained by professionals. 5. Do not store the electric fan in a humid environment, which may cause the motor to rust. 6. If the electric fan is not used for a long time, you need to turn off the equipment and unplug the power plug.

It's still spinning just now.

All of a sudden, it doesn't turn.

1. Lack of oil and deformation.

1. It is normal for novices to sound the computer fan.

2. During the operation of the computer, the fan is running all the time, if the fan is abnormal or the temperature is too high, it is mostly not good for heat dissipation, you can add a radiator to try.

4. Finally, the position may be offset due to excessive dust accumulation of the exhaust fan or loose fixing screws, you can clean up the dust and re-fix the screws.

Generally, if it is a new computer, the fan rings normally, if you feel that the sound is unacceptable, you can contact the after-sales service to check whether the fan has quality problems. Bucket potatoes with.
