What to do if your computer s bellows are loud 10

1.The ambient temperature is low in winter, and the general power supply fan is louder when starting, and the sound gradually decreases after preheating. CPU fans are less affected inside the case. In addition, in winter, outdoor personnel activities are reduced, the outside noise is reduced, and the noise of the chassis is increased.

2.The reason for the loud fan may also be that there is a lot of dust. For CPU fans can be removed and cleaned with a small brush, including the heatsink.

It is best not to refuel the CPU fan, there is a certain chance that it will affect the power supply and cause damage to the motherboard. In addition, the original fan generally runs very stable after cleaning, and the sound is smaller. If you use a non-original CPU fan and the noise is still loud after cleaning, it is recommended to replace the brand fan, and you get what you pay for.

For the power fan, you can remove the power supply and turn it on for cleaning, which is very simple. Be careful not to use brute force to avoid desoldering of the solder joints of the internal components. In addition, you can turn on the power fan for refueling, tear off the label and open the leather cushion and use watch oil or sewing machine oil to add two drops, and pay attention to wipe the excess oil on the fan after adding.

3.In addition, the silica gel on the contact surface of the CPU fan and the CPU under the CPU should be thinly wiped evenly, and the grooves on the heat sink should be filled to make them in good contact, which can improve the heat dissipation performance, so that the CPU fan speed will not be too high, and the sound will naturally decrease.

4.In general, in a relatively clean home environment, the chassis should be cleaned once a year (like people, it will take a year every year :) You can use a hair dryer (note that you can only use the cool breeze block, not hot air on the motherboard and other components), leather tigers, etc., you can borrow an electric sootblower if you have the conditions, and after cleaning, the sound will be much smaller.

You might as well give it a try.

5.In addition, fix the screws of the chassis panel, etc., firmly hold the chassis against other objects, and put some leather pads underneath to reduce the vibration of the chassis, which can also have a certain noise reduction effect.

It may be the vibration sound caused by the fan speed is too fast, first see which fan is louder Add a speed reduction line to the fan, but this will have an impact on heat dissipation.

It should be a fan problem, it turns out that my computer is also like this, just change to a fan with low sound!

Is it the CPU fan or the power supply fan is loud, is it new, you can change the fan and power supply for a long time.

The sound of the fan of the power supply is right.

How to deal with the noise of computer fans:1. The sound of the computer fan is almost always due to the high load of the computer, which makes it difficult to exhaust the volume, we can exit the software that has been opened by the computer, and reduce the computing load of the computer first.

2. You can also open software such as Master Lu for hierarchical cooling, such as Master Lu, we can turn on "comprehensive energy saving" in it for cooling.

3. Of course, it can also be carried out in the form of hardware dust cleaning, and the effect will be more significant.

Computer fans, also known as cooling fans, are generally used to dissipate heat. Available for use in radiators and chassis. The general cooling fan on the market is available in size from diameter to 30cm, thickness from 6mm to 76mm, and according to different operation requirements, rare AC (AC, power from household sockets) and common D power supply (DC, through the computer fire cow or motherboard power), most of the use of two-phase motor (two sets of copper coils, a total of four units), in the case of low speed is conducive to saving production costs.

1. Dust blockage. The dust accumulation of cooling fans is one of the reasons for the loud sound of the computer case fan. We can first pry open the interface on the keyboard, use a screwdriver to disassemble the screws under it, and then remove the keyboard, optical drive, and hard disk accordingly, so that you can see the cooling fan, and finally use a vacuum cleaner to suck off the dust on the panel, power supply, radiator, etc., and then wipe the inside of the chassis with a rag dipped in alcohol, put it in the vent to dry it, and then install the computer back.

2. The fan shaft is rusty. If the noise is caused by this reason, we can follow the above steps to disassemble the computer, after seeing the computer cooling fan, drop the lubricating oil on the fan bearing, we can also use sewing machine oil instead, and then install the computer back.

3. The fan blades of the fan are eccentric. If the screws of the computer fan are loose, there may be a situation where the fan blades are eccentric, if the case fan is loud due to this reason, we can take the computer fan apart and reinstall it, pay attention to tighten the screws of the fan, so as not to loosen the fan again. Finally, install the computer back and you're good to go.

4. The configuration of the computer is not high. If it is caused by the low configuration of the computer, such as the aging of the computer power supply, the full load of the computer, etc., we can replace the new computer power supply or upgrade the CPU, graphics card and other accessories according to the specific situation.

5. Wire arrangement. The computer fan touching the cable is also one of the reasons for the noise of the case, we can first open the computer case, carefully check its cable, rearrange the computer fan touching the cable, and install the computer back.

6. After-sales. Of course, if the computer is within the warranty period, we can directly ask the after-sales service to help deal with it. If you are worried that you will not be able to handle it well or that it is too troublesome, we can also ask a professional to deal with it.

The solution to the noisy fan of the computer host is as follows:Operating environment: Inspiron 5570, applicable system: Windows 10 home Chinese version, etc.

1. First, right-click [This Computer], select [Properties], and open [Control Panel Home].

2. Tap Power Options and find the plan shown on the battery indicator.

3. Open [Change Plan Settings] on the right and select [Change Advanced Power Settings].

4. Under Advanced Settings in Power Options, select Processor Power Management.

5. Open the [System Cooling Mode] option, and use the battery to modify it to [Passive].

6. Click [Apply] after completion, select [OK], and close the interface.
