My computer CPU fan is loud, is it normal?

Generally speaking, the sound of the CPU fan is not heard, and what is heard is generally the sound of the fan on the case. If you find it after opening the case, then I suggest you reinstall the fan. Of course, you can also use the software to test the speed of the fan to see if it is normal.

However, we are always suspicious of new machines, and when I first bought them, I always felt that the fan was too loud, and I gradually got used to it

It is normal for the fan noise of the original package CPU of Intel's Celeron D series to be noisy, and you can go to the market to buy other silent fans of the 775 series to solve the problem, which costs about 40 yuan.

Generally normal.

The sound may be that there is dust on the fan, and it is more audible when it turns.

One is that the voltage of your CPU fan is not enough or unstable, and the fan speed is not normal, and the sound will be loud.

That is, the quality of the fan is not high, and the sticker on the back of the fan is removed. Add two drops of sewing oil, not other oil, and seal it well. Make sure you're okay for ten days and a half months, just change it in time, twenty can be changed, fifty can be changed to a good one,

I'm suspicious right now, because the fan is a little louder. I am afraid that the fan will break down and burn out some hardware all day long. Hehe.

It is normal for individual fans to be loud, and the speed of the fan can be checked through the motherboard monitoring software.

If the speed is normal, it doesn't hurt!

People can be said to be inseparable from the Internet in their lives, so many people will have computers. The situation of the loud CPU fan of the computer must have experienced it personally by many friends. How to solve this problem, let's introduce the loud voice of the computer CPU fan in detail.

Causes and solutions.

Computer CPU fan is 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.

How to solve the problem of computer fan noise:

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 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.

Computer CPU fan is loud? The above is the introduction and solution to the reasons why the computer CPU fan is loud. If none of this makes the noise problem solved, then the CPU fan is working properly.

It may be that there is a problem with the hard drive, you can find a professional to take a look.

1.Some computers may not have a high configuration of the equipment, and the sound is relatively loud when it is turned on, and it will slowly become smaller later, which is a relatively normal phenomenon.

2.If the fan is still loud after a long time, it may be that the shaft of the fan is rusty, you can apply less oil on the shaft and lubricate it.

3.It may also be because the fan has scratched something, you can open the fuselage to take a look.

4.Dust behind fan blades and radiators should be cleaned frequently.

5.The "eccentricity" of the fan blades is the main cause of high noise, so it is necessary to reinstall the fan firmly.

6.If none of these can solve the problem, it may be that there is a problem with the hard drive, and you can find a professional to see.
