What s the deal with the noisy host and the noisy host of the computer?

This one must be a fan problem!

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.

There are two ways to eliminate CPU fan noise.

The bearings and blades of the CPU fan are the most noise-causing places, and after long-term use, the bearings of the fan may rub too much due to lack of oil, resulting in large noise.

Solution: Add some oil to the fan shaft. The specific operation is to carefully uncover the label on the fan shaft, add oil and then cover it.

If the quality of the fan blades is not very good, after a period of rotation, the fan blades may be deformed due to heating, touch the inner wall, and make noise.

Solution: Take the blade and gently scrape the scratch a few times to increase the distance between the fan blade and the inner wall to avoid friction between the two.

Don't forget to clean the gap between the back of the fan and the heatsink, as it is easy to accumulate dust here.

There is still noise after changing the fan!

Then I'll give you an analysis, the problem with the CPU fan must be very small, and the probability of a problem with the CPU fan is multiplied by the probability of a problem with the newly bought fan.

Then it could be a problem with the power supply.

In addition to the power supply, there are other possibilities, you may also have a graphics card fan in your machine, if you are not afraid, open the case after the noise starts, shake the graphics card, and listen to the sound pitch change. If you take another one (fingers are OK) and touch it to the fan of the graphics card, is there still any noise?

There are still words. If you don't have any other fans in your machine. Then the probability of an accident with the power supply is Daluo = 1 - the probability of a problem with the CPU fan * the probability of a problem with the newly purchased fan" = 90%.

There are several reasons why the console is too loud.

1。Due to the constant use or multiple disassembly and assembly of the CPU fan, the thermal conductivity of the silicone will be reduced, and the problem will be alleviated after replacement.

2。Replacing the CPU or power supply fan may cause the fan to rotate out of balance due to long-term wear and tear, and there are not many chances of problems with the graphics card fan, and the current graphics card fan power is not very large.

3。The assembly machine, the chassis resonates with the power supply and the CPU fan, and this problem can be temporarily solved by removing the side cover in addition to replacing the chassis. Of course, the dust protection effect is not good.

Friend Ming, I am engaged in electronic technology, and your machine is not a fan problem. If you think about it, how can there be a problem with the newly bought fan, not to mention that your computer is running normally, this is a problem with the power supply, but your power supply is not good, it is the sound of the hub in the power supply, which may be caused by the poor environment, the voltage is not stable or there is a problem with the power quality. I recommend you to change to a new one, the current power supply is not very expensive, otherwise the consequences will be unimaginable after a long time.

With a low-speed hard disk, the optical drive is 8 times faster, the system fan should be frequently dusted, lubricated, and the power supply should be stable and powerful, so that there will be no overload noise.

The CPU overheats, causing the fan speed to increase, so the noise is relatively loud.

The motherboard is noise-free, caused by dust staining the CPU fan and power supply fan!

Problems with the power supply, put some oil on the power supply,

Replace it with a silent fan, it will definitely work well.

Can you describe in detail what you heard?

There's too much dust in it, just take it apart and blow it off with a hair dryer, and mine used to be like this.
