About the problem that the computer is very noisy after it is turned on

The noise of the computer depends on what characteristics there are. A slight whirring sound is the "wind sound" when the fan is working, which is normal. If it is an intermittent "click" sound (the sound is also soft), it may be the sound of the hard disk reading, and you can't do anything about it, except for the backup of important files, you can ignore it.

The optical drive will also emit sound sometimes, but there is no sound when it is not working. If it is a continuous "roar" sound like a motor or chainsaw, it is the sound of the fan due to dust accumulation or lack of oil, and it is most likely to sound for a while when the machine is turned on. The solution is (1) brush the ash and put some oil on it; (2) Replace it with a new one.

If you are not afraid of trouble, the former is both economical and practical. To apply oil, uncover the circular covering film in the middle of the fan, let the shaft be exposed, drip a little high-grade lubricating oil (do not use cooking oil, because the cooking oil will be sticky for a long time, affecting the operation of the fan), and then cover the film. Sometimes not all of them are ringing, how can you tell which fan is ringing?

You can take a chopstick, open the case to turn on the power, put one end of the chopsticks on the board with a fan, and the other end on the face, feel a significant vibration, and the vibration disappears with the "roar". After brushing and oiling, the problem could not be solved, so it had to be replaced with a new one.

What should I do if the computer's cooling fan keeps making a "roaring" sound?

Lubricate its shaft. Method: Uncover the paper at one end of the hinge, you will see the hinge, add an appropriate amount of sewing machine oil (even cooking oil) to lubricate, which will greatly reduce the noise of the fan.

The sound of the hard disk is loud, the sound of the hard disk is mainly a gurgling sound, the hard disk of bad quality will be louder, and if the hard disk fragments are too much, the workload of the hard disk will be increased and the sound will be louder, and there is a situation that the hard disk has a bad sector, which will also lead to the sound of the hard disk to increase, just scan it, and defragmentation should be done, by the way, BT and other **tool** files will produce a large number of disk fragments, and the solution is to dump the movie that has been ** every time ** is completed, Save to another partition.

The resonance of the computer noise reduction strategy.

The radiator of the computer noise reduction strategy.

If the sound is still loud after cleaning the dust, it may be that the fan speed is not constant due to the unstable voltage or current of your motherboard, you can check whether the motherboard has capacitor burst or it is caused by the aging of your old power supply, or it may be that the fan fan is loose.

First confirm how your system is, if not, make the system, which is also related to the system, and then clean the dust in your case to see how it is, and then see if it is the CPU fan, check which one is louder, and then repair.

Maybe it's a fan problem!

The noise of the CPU fan is solved as follows:

Many friends' computers will buzz in the box when they are first turned on after a period of time, and they will return to calm after a few minutes. People generally don't pay much attention to this problem, and some people will pat the case a few times to reduce the noise.

In fact, this is a manifestation of the lack of fuel in the CPU fan or power supply fan, which is not conducive to the safe operation of the computer.

Let's start with the cause of the noise:

When the fan has been running for a long time (usually after two or three years, this phenomenon begins to appear, and a better fan can rotate longer), the lubricating oil in the fan oil bladder is exhausted, and dry friction occurs in the fan bearing, resulting in noise. After the machine is turned on, the fan rotor is not in its equilibrium position, and after a period of rotation, the dust in the bearing gap will be worn off, or grinded finely, so the noise will become smaller for a period of time, and this is also the reason for the noise to become smaller, which is to return the bearing to the equilibrium position with the help of external force. But this is very unsafe, because the hard disk is spinning at high speed when the computer is running, and at this time, the hard disk will vibrate, which may cause the hard disk to produce physical bad sectors, so be careful!

At this time, if the lubricating oil is not added in time, the fan will be damaged, the bearing gap will be worn more and more, and the noise will become louder and louder, until the fan is scrapped; In severe cases, the CPU has poor heat dissipation, and it often crashes or restarts for no reason, and in more serious cases, the CPU may be burned.

However, there is no sound when it does not work. If it is a continuous "roar" sound like a motor or chainsaw, that is, the sound of the fan due to dust accumulation or lack of oil, open the case to turn on the power, put one end of the chopsticks on the board with the fan, and the other end on the face, feel obvious vibration, and the vibration disappears with the "roar", how to determine which fan sounds? Take a pair of chopsticks.

To apply oil, uncover the circular covering film in the middle of the fan, so that the shaft is exposed, because the cooking oil will be sticky for a long time, affecting the operation of the fan), and then cover the film. Sometimes not several fans are ringing, dripping with a little high-grade lube (do not use cooking oil to see what the noise of the computer is characteristic. A slight whirring sound is the "wind sound" when the fan is working, which is normal.

If. It's an intermittent "click" sound (the sound is also softer), it may be the sound of a hard disk reading, you can ignore it. The optical drive also sometimes emits a sound. The solution is (1) brush the ash and put some oil on it; (2) If you change to a new one, you can't do anything about it.

If you are not afraid of trouble, the former is both economical and practical, in addition to doing a good job of backing up important files, most of them are good when they are turned on for a while.
