Ask the master to answer the problem of netbook fan noise

The fan is loud, which is relatively normal in a netbook, so buy a cooling table stand.

After plugging in the headphones, the problem that the speaker is still ringing,,It's more tragic。。。

Do you have sound in your headphones...

It seems that this voice tortures you very depressed.

You judge whether it's the sound of the speaker or the sound of the machine, and if it's the sound of the machine, you guess your hard drive is tragic. Return it to the seller for repair. As usual, there is a warranty period.

The newly bought netbook on the ****,There was basically no sound when it was just turned on.,After running for a while, the fan noise got up.,It's very big.,It's very uncomfortable.。

But if you change the orientation of the netbook, for example, put the keyboard perpendicular to the ground, this noise will be gone, and I wonder if the fan is not fixed properly, resulting in friction with the body to make such a loud noise. Please help diagnose it and see what the problem is, so I can decide whether to return it.

Normal thing!! Or a lot of dust or, the fan rack is broken. It is recommended to disassemble the chassis for inspection. I've also tried that the fan's rack is broken!

There are several possibilities for a noisy fan:

1.The fan is running out of oil. You can turn on the computer host, find out which fan is ringing, and then gently open part of the label in the middle of the fan, go out of the bearing inside, add a little lubricating oil to the bearing, and then seal the label tightly.

2.The fan has dirt. Find the fan that is ringing and clean the dust on the top of the fan and the middle bearing part.

3.The fan bearing is faulty, or the fan is not stable. The easiest way to do this is to replace it with a new fan, which can be done for a few tens of dollars. This kind of fault is difficult to repair and is not worth repairing.

4.The fan is fault-free. But what you set in your computer's BIOS is the CPU fan at full speed. In this case, the fan will not adjust the fan speed according to your usage, so the fan will rotate at full load when turned on, resulting in a lot of noise.

5.You set the fan to adjust the speed. However, because the contact between the fan and the CPU is not close enough, resulting in poor heat dissipation, the CPU temperature is continuously high, so the fan runs at full speed.

In this case, you need to remove the heat sink, clean it in the middle, apply silicone grease, and then buckle the fan tightly.

The easiest and most practical way is to go down yourself.

Then use a toothbrush or hair dryer to get it.

It's definitely going to be a lot better than the original.

If you don't believe me, you can give it a try.

Very practical.

You clean up your computer dust.

Clean up the CPU as well as the graphics card, the cooler, the dust, the fan, and add some lubricating oil.

What is the situation? Otherwise, there is no way to judge. Some of them are loud as soon as they are turned on? Some of you are running larger software before you start talking loud?

In general, laptop fans adjust their operating status according to the temperature of the CPU and GPU. If it is in a light resource occupation, the laptop fan is in standby mode. So at this time we can't hear the sound of the laptop fan.

When running professional design software or large-scale 3D games, the demand for heat dissipation increases due to the rapid rise in CPU and GPU temperatures, so the laptop fan runs and adjusts the speed to accelerate heat dissipation. At this time, the laptop fan is loud, which is a normal phenomenon.

After talking about normal phenomena, it is the turn to talk about abnormal situations.

1.If the laptop fan continues to work when the CPU is not under high load, it means that there is a problem with the adjustment system of the laptop fan and the fan is in an uncontrolled state. At this point, you can try flashing the BIOS to restore control.

If the problem persists, it can be judged that the laptop fan cable is loose and the control fails.

2.Laptop fan eccentricity causes laptop fans to be loud. Due to improper use, the laptop collides or the laptop is placed at an angle that is too tilted, resulting in the offset of the axis of the laptop fan and the noise caused by bearing friction.

If you still have the problem of the laptop fan being loud after trying to place it horizontally, you will need to contact after-sales service for a replacement.

3.Dust deposits cause laptop fans to be loud. After a period of use, a lot of dust will be absorbed inside the laptop, especially on the fan blades of the laptop. At this time, it is necessary to disassemble the machine to clean up the dust.

1. I encountered the same problem as you, there was an amazing roar in the box when the machine was turned on, and after a few minutes, the computer returned to calm, and everything was normal!

In fact, it's not the CPU fan and hard disk at all, it's the optical drive! This is the culprit!

I've tried n times, but it didn't work, and finally found out that it was a problem with the optical drive.

2. When the optical drive is working normally, the motor drives the disc to rotate very fast. Generally, the rotation speed of the ordinary 40 times speed optical drive or 32 times speed optical drive disc reaches 7000 revolutions per minute, and the noise emitted also reaches 50 decibels.

The noise of optical drives is mainly divided into mechanical friction noise and mechanical vibration noise. The former is derived from the friction "wind sound" emitted when the optical drive spindle motor drives the disc to rotate at high speed, and the friction noise when the spindle motor drives the laser head to move up and down when the disc is read, the higher the speed of the optical drive, the greater the noise; The latter is the noise caused by the vertical and parallel vibration caused by the high-speed rotation of the optical drive spindle motor and the vertical and parallel vibration caused by the upward and downward movement of the optical head when reading the disk.

Similarly, the higher the speed of the optical drive or the poor quality of the disc, the optical drive will produce disc eccentricity, weightlessness, shaking and other phenomena when reading the disc at high speed, thus causing greater mechanical vibration noise.

3. The best way is to replace this aging optical drive!

There is no need for oil in the computer, you should take the computer outdoors and blow the dust with a hair dryer, your situation should be the reason for the dust, it should be the problem of the power supply fan, not the CPU fan.

There are about two kinds of CPU fans, one is balls and the other is hydraulic, the latter needs to be refueled, open the sticker on the fan, and use the sewing machine oil pot to drop it. Note, though, that this doesn't solve the underlying problem. It is recommended that the landlord change a radiator, dozens of dollars with a fan.

Judging by your phenomenon, it should be the sound of the power fan. After cleaning, it will be better to tighten the power screw and add a spacer.

It seems to be a problem with the CPU fan.,The service life of this fan is one year.,And the price is more than 100 yuan.,It's terrible.。。

The cheap solution is: first kill the virus yourself, but it really doesn't work, so you have to hire a professional.

The problem of the power supply fan, even if you find a way to deal with it, there will not be much time to do this, or change the power supply honestly.

There are several reasons for fan noise: 1. The fan itself is not fixed properly, the screws are not tightened, and there will be noise when working in an active state. 2. The rotating shaft of the fan is rubbed badly, in this case, it is necessary to clean the dust on the fan from time to time and put some lubricating oil on it.

3, that is, the motor of the fan is about to be scrapped, I hope yours is not in this situation!

Generally speaking, the fan rotation will be more or less a little sound, don't be too sensitive, if the noise is very loud, most likely the chassis has frequent leakage (with a pen can be measured) long-term electromagnetic interference will make the fan noisy, in addition to the above situation, this needs to be diagnosed by yourself What is the situation...

These problems are not big, in addition to noise, the main fear of heat dissipation performance, you use Master Lu and other software to see how much the usual temperature is, if it is too high (especially in summer), you have to consider changing the fan, otherwise there is a hidden danger of burning.

It's not a big problem, as long as you're not afraid of noise!

It's time to change the heatsink on the CPU.

Generally, the cooling fan is empty, blocked, cleaned, self-understanding, computer maintenance, and then buy a cooling point, base or pad.

1.It may be a quality problem with the fan itself, it is recommended to call the after-sales replacement to try it, and change it as soon as possible, otherwise it will hurt the CPU!

2.After you turn on the fan power supply, turn on the power to test the voltage of the fan input pin, the normal should be less than 5V, if it is too large, there is a problem with the motherboard, it is recommended to send it for repair.

3.If the above is normal, then measure the resistance of the fan to see, compare it with a good fan, if the fan resistance value is abnormal, it is a problem with the fan, and change the fan.

- Obscene division ———

Also, the biggest problem for many notebooks is heat dissipation, if the laptop wants to make the CPU temperature reach a normal state, the fan will run at high speed, so the fan is relatively loud.

It is recommended that the LZ get a new fan.

During the warranty period, the fan quality problem is covered by the warranty, and the attitude is tough, and there is no problem with replacement.

Because the fan is not man-made damage, and the noise is serious in half a year!

goodluck~

1. The most important thing is to run the software, that is, the program is being processed, for example, when you insert the disc and start reading the card, there will be a lot of noise. These are inevitable -

2. Inside the notebook, especially the fan sucks in dust, you can buy a notebook vacuum cleaner (there should be one in the electronics store), usually do not put it externally, that is to say, put the notebook outside must add a layer of protective film on the outside

3. If there is a problem with the quality of the fan or notebook, this can only be replaced with a better one!

If you can really rule out the above reasons, there is only one answer, one thing is certain, your fan is definitely a high-power and high-speed fan, and it is not a silent fan!

The size of this book is a large-size book, with may be AMD's processor, the manufacturer in order to strengthen the heat dissipation, save costs, use non-silent fans to install, the fans of general brand machines are silent fans with good performance, low power consumption, low noise, small blades, it is difficult to make a high-power fan silent, after all, the blades are relatively large, and the noise temperature point can not be controlled, Dell's machine is particularly numerous, and he must save configuration costs if he is cost-effective!

If the impact is not great, it is recommended not to change the fan! Because this is the manufacturer's configuration, the fan used is calculated for the temperature point.

First of all, the fan of the notebook can't be oiled, what kind of oil is it, it's all magnetic coils, not bearings.

What kind of sound is it?

Is it the sound of a fan blade hitting a hard object?

Or, a squeaky sound?

In either case, you can go to a repair center and have the fan replaced!!

It is this friction sound caused by the failure of the fan.。。

After ruling out the reasons stated by the landlord, it is likely that the fan noise is caused by some software of the upgraded system.

Most likely, it is the reason for upgrading the BIOS, HP had such an example some time ago, and later a patch was launched, but it did not work much. The landlord can consider whether there has been a recent upgrade to the BIOS or the manufacturer's software of the system.

I think the landlord said that the noise is definitely not small, beyond our general range, so I advise the landlord to take it to the after-sales service as soon as possible to repair, not to mention the old crash, don't use it anymore, there must be a problem with the CPU fan that caused the crash, when the CPU burns out, the after-sales service is not good to speak!
