The noise from the tablet fan is too loud, giving people a headache. PHP editor Xigua learned that there are many reasons for excessive fan noise in tablet computers, including poor heat dissipation, poor fan quality, and system overloading. In order to solve this problem, the editor will introduce in detail the causes and solutions of excessive tablet fan noise to help everyone eliminate the noise troubles of tablet computers.
1. What to do if the computer fan is noisy
1. Lubricate the bearing
The most important component of the fan is the bearing. If the fan is lacking lubricating oil over time, noise will be generated when it rotates at high speed. Therefore, we only need to put a few drops of lubricating oil on the fan bearings, which can be replaced if a sewing machine is not used. But be careful not to use edible oil instead, because its particles are relatively large and can easily cause damage to the bearings.
2. Fixed fan blades
Vibration noise is also an important component of fan noise, because the blades are loose on the bearings and the bearing wear causes the gap to become larger, etc. Therefore, you only need to remove the fan blades and tighten the screws. Once firmly fixed in this way, it will no longer vibrate.
3. Polish the fan blades
In addition, poor quality cooling fans are used. Due to process defects in the production of such fans, the center of gravity of the fan blades may not be on the axis, resulting in "eccentricity" and the use time will be long. Over time, the fan's "eccentricity" phenomenon will become more and more serious, which will not only produce noise, but may also seriously damage the CPU. In this regard, you can dismantle the cable and hang it in the center with a thin wire. After it is still, see which direction it sinks. Gently grind the sinking end on the grinding wheel for a few times, and then test it. Install the fan after it can be in a horizontal position.
I believe that through the above three tips, the fan noise can generally be eliminated.
Basically cleaning the dust and replacing silicone grease can solve the problem, but it is recommended not to do it yourself. If you want to do it, go to a repair center
The sound of the Redmi computer fan is mostly caused by abnormal sound caused by the computer fan being blocked by dust or foreign matter. In this case, you need to open the back cover of the computer case, find the position of the fan, use a brush tool to clean the fan and see if it is Can restore normal sound
Solution:
1. Check whether the cables in the chassis are reasonable. If they touch the computer fan, you can rearrange the cables;
2. Tighten the screws fixing the computer fan to avoid loosening of the computer fan. Causes the chassis to be loud;
3. Regularly deal with the dust accumulated in the chassis, especially the dust on the computer fan. You can use a small soft
4 to dismantle it yourself. Simply put, first remove it on the keyboard. Pry open the place where the interface is, and then remove all the screws at the bottom. First take off the keyboard, then take off the optical drive from the rear, take off the hard disk, and then you can take it apart and see the cooling fan, and you will know what it is. Problem.
5. It’s not a big problem if the fan is broken. If you want to replace the fan, it depends on the specific model. The fan is short of oil. If the product is under warranty, go to after-sales service. If it is outside warranty, buy sewing machine oil yourself.
1.
Open the settings on the computer, and then we click on System.
2.
Then we click About and click Advanced system settings.
3.
Then click Settings in Performance.
4.
Then click to select Adjust for best performance and click OK. This way the fan won't be too loud.
1. In winter, when the ambient temperature is low, the sound of the power supply fan is generally loud when starting, and the sound gradually decreases after preheating. The CPU fan is less affected inside the case. In addition, outdoor people's activities decrease in winter, and external noise decreases. It feels like the chassis noise increases.
2. The reason for the louder fan sound may also be due to the accumulation of dust. The CPU fan can be removed and cleaned with a small brush, including the heat sink. It is best not to add oil to the CPU fan, as there is a certain chance that it will affect the power supply and cause damage to the motherboard. Moreover, the original fans generally run stably and make less noise after cleaning. If a non-original CPU fan is used and the noise is still loud after cleaning, it is recommended to replace it with a branded fan. You get what you pay for. For the power supply fan, you can remove the power supply, open it and clean it, which is very simple. Be careful not to use brute force to avoid desoldering the solder joints of internal components. In addition, you can turn on the power supply and refuel the fan. Tear off the label and open the leather pad, then use clock oil or sewing machine oil and add two drops. After adding, be sure to wipe off the excess oil on the fan.
3. In addition, the silicone on the contact surface between the heat sink under the CPU fan and the CPU should be evenly spread thinly, filling the grooves on the heat sink so that they are in good contact, which can improve the heat dissipation performance and prevent the CPU fan from excessive speed. High, the sound naturally decreases.
4. Generally, in a relatively clean home environment, the case needs to be cleaned once a year (just like people, they have to celebrate the New Year every year:)). You can use a hair dryer (note that you can only use the cool wind setting, and do not damage the motherboard) (Blow hot air on other components), leather tigers, etc. If possible, you can borrow an electric dust blower. After cleaning, the sound will be much quieter. You might as well give it a try.
5. In addition, fix the screws of the chassis panel firmly, place the chassis against other objects, and put some leather pads underneath to reduce the vibration of the chassis and achieve a certain noise reduction effect.
The fan lubricating oil freezes in the winter, and the temperature will rise after a while after turning on the machine.
2.
When the computer is turned on, the reason for the fan noise may be that the fan bearings are worn. Try changing to a good fan, it may be fine. The power supply fan needs to be filled with oil every few months, preferably a car The engine oil I used is still dusty.
3.
Tear open the trademark on the fan, and you will see a small eye. Just apply a drop or two of engine oil with a screwdriver.

Recommendation: If the computer working environment is dirty, the power box should be cleaned once a year. Even if the fan does not sound, considering the pile of dust on the circuit board, you should clean it!
The sound of the fan in the case is getting louder and louder. The reason is that the fan bearing is short of oil and the bearing hole is worn - the gap between the fan shaft and the bearing is too large, and the axial movement gap of the fan is also too large, and the fan blades can move back and forth a few millimeters. After the fan rotates, it moves axially, and the rotation plane of the fan blades also shakes. Not only does the wear become more and more severe, but also a lot of noise is produced.
