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.

Anonymous users2024-02-10You got the clutter in when you got the dust! Or is it a fan that hasn't been cleaned for a long time! You cleaned up after the ashes!!
But it's already dry inside! You can use sewing machine oil! Drop a little bit!
That's it! It's the easiest and most effective! I'm a professional repairer!
Hehe! Yes!

When there is noise in the turning fan, you can take the part where the metal sleeve in the middle of the page is smeared with butter and rubbed with the shaft rod, and at the same time, the plastic gasket should be used to adjust the distance between the page and the body to keep it moderate, not too close, so as not to rub the body due to the deformation of the page and make a noise;
2. Check the bearing motor, if there is a lack of oil, remove the motor, take out the tile sleeve, clean it with oil, and inject oil into the felt pad to make it absorb the loss and full of oil, and reinstall the motor;
3. Check whether there is any damage to the root of the fan blade, and replace the fan blade in time if there is a sail hall;
4. The gear in the gearbox should be checked due to the noise caused by the gear occlusion of the gearbox of the electric fan, and the gearbox can be replaced directly if it is damaged;
5. When noise is generated due to unstable placement, the fan should be checked to ensure that it is placed smoothly, and all the loose parts of the fan should be tightened to ensure that no noise will be emitted.

Anonymous users2024-02-08There are usually several possible reasons why a computer fan suddenly becomes louder:
1.The fan itself is aged or damaged. Computer fans will deteriorate and wear out after long-term use, and damage to bearings and other components can lead to increased fan loudness or vibration. At this point, you need to replace the fan to solve the problem.
2.The radiator is clogged. The CPU fan is responsible for taking away the heat generated by the CPU, and if the cooler is clogged with dust and other debris, the fan needs to increase the speed to enhance the heat dissipation, which will cause more noise. Dust needs to be cleaned from the radiator.
3.The temperature sensor is out of order. The computer will automatically adjust the fan speed according to the CPU temperature, if the temperature sensor is damaged, the fan speed will be abnormal, resulting in louder noise. You need to replace the temperature sensor that comes with the motherboard or fan.
4.CPU overheating shouts. If the CPU is working at high temperatures for a long time, the fan will inevitably spin faster to enhance heat dissipation, which will also cause the fan to become noisy. You need to check the CPU usage and cool it down.
5.The fan speed is not set properly. If the fan speed control option in the motherboard BIOS is not set properly, the fan speed will be too high and noise will be generated. Go to the BIOS and restore the fan speed setting to default or lower.
6.Fan wiring is loose or in poor contact. If the speed signal cable or power cord of the fan is not in contact properly, it may also cause the wind to seep into the fan and cause noise due to abnormal operation. The fan needs to be removed to check the line contact, and replace the fan if necessary.
In summary, there are many reasons why a computer fan suddenly becomes louder, and the common ones are fan damage, radiator blockage, temperature sensor failure, CPU overheating, and fan setting problems. You can try to troubleshoot the fault according to the noise characteristics of the fan, or take it directly to the maintenance center for detection to determine the root cause of the fault, and repair or replace the fan to solve the problem.
The temperature of the laptop is related to the use environment and the occupancy and load of the CPU and other components, if you feel that the current machine temperature is too high, you can try to increase the heat dissipation base or raise the bottom of the laptop to see if it will improve. If the effect is not good, it may be caused by excessive dust on the computer or improper heat dissipation. You can go to an HP repair outlet to clean the machine and take a look.
When the computer runs 3D games, the information and usage rate in the CPU are much higher than usual, the higher the load, the higher the temperature, your motherboard has a temperature control speed regulation function, when your CPU temperature is too high, the motherboard will automatically speed up the CPU fan, to achieve the purpose of cooling, to avoid your CPU working at high temperatures, (CPU long-term work at high temperatures will reduce the service life).This doesn't have much to do with the small memory. It's just that the fan speed is high, and the noise is high, if necessary, you can consider changing to a better radiator, many brands of radiators are good, the heat dissipation effect is good, the sound is quiet, but expensive!!
This is because the temperature is too low, the activity of the oil is not enough, so you don't use refueling, many people think that the lower the temperature in the case, the better, in fact, it is not, it has a requirement that the fan will rotate at high speed when the computer is just turned on, at this time, if the fan is short of oil, it will be very loud, and the sound will be much smaller after entering the system. After excluding the vibration caused by the fan and the sound caused by objects touching the fan blades, the most likely thing is caused by the lack of oil, the refueling method is very simple, first remove the fan from the seat (nonsense), and then see if the back of the fan (a few in the front) is glued with a round plastic sheet, generally sticker. >>>More
