Why does the computer sound loud when it starts up? Computers are like this. They need to do a good job of cooling when they are turned on, so the fan sounds louder. Also, when the hard drive first starts spinning, the motor sound is relatively loud. The above is normal unless the sound is extremely loud! It may be caused by the CPU or the power supply fan.
This situation is usually caused by cold weather, which causes the oil in the CPU fan shaft or balls to freeze, or the oil in the power supply fan shaft or balls to freeze, causing the computer to start up with a very loud sound. Generally, after the computer has been running for a period of time, When the computer heats up and the oil melts, the sound will be normal. This situation usually occurs in winter.
Then check whether the ambient temperature is low, the lubricating oil has solidified, or it has been used for too long and the lubrication is not enough, making it difficult to operate, so the sound is loud or the fan has too much dust to make the sound loud. If you don't know how to do it, you should go to a specialist. Department for maintenance.
The reason why the fan makes a loud sound when the computer is turned on: When the computer is turned on, the fan is running at full speed, so the sound will be loud, but during normal operation, the speed will slow down and the sound will be soft. Because today's motherboards are automatically controlled by the BIOS and automatically adjust the fan speed according to the temperature.
The buzzing sound the computer makes when it is turned on is the sound of the cooling fan starting. When the computer is running normally, the motherboard will dissipate heat seriously. In order to reduce the temperature and ensure the smooth operation of the computer, the manufacturer has designed a cooling fan for the computer. The buzzing sound your computer makes when it starts up is the sound made by the fan.
It is normal for the computer to make a loud sound when it is turned on. Reason: Because the system will detect the hardware when it starts. The computer will detect the fan when it is turned on. There is a loud noise when starting up upstairs. This may be the reason for the loud whine when you turn it on. When I just restarted again, it was because it had been started once.
1. If the noise is caused by the power supply, the noise is caused by excessive dust or aging of the power supply and insufficient power. Disassemble the screws of the power supply, clean the dust with a brush, and pour lubricating oil on the shaft. Method 2 If the noise is caused by the CPU fan, the solution is as follows.
2. Here are some methods that may be useful to eliminate computer fan noise: Clean the dust inside the computer, especially the fan. Use a can of compressed air or a professional vacuum cleaner to clean the inside of your computer and make sure there is no dust or debris accumulated near the fan. Replace the fan. If the fan cannot be cleaned thoroughly or is worn, the fan may need to be replaced.
3. This is because when the weather temperature is not high, the grease in the CPU fan is somewhat solidified. In the early stage of startup, the temperature of the fan bearing is low, the grease viscosity is high, and the rotation resistance is large, so the sound is loud. After rotating for a period of time, the temperature of the fan bearing part increases and the lubricating oil starts to work.
Replace the fan. If the fan cannot be cleaned thoroughly or is worn, the fan may need to be replaced. You can choose a quieter fan or try a water cooling system. Adjust computer fan settings. In the BIOS settings or operating system, there may be some options available to adjust the computer fan. You can try lowering the fan speed.
First of all, we need to determine where the noise is coming from. If the sound is in the middle and upper part of the rear of the chassis, there should be a problem with the fan of the chassis power supply. Remove it and add some lubricating oil. If there is no special fan , adding some peanut oil and olive oil is also a temporary solution.
Check the graphics card fan. In the computer host, except for some host cases with their own fans, there are usually three components with cooling fans. (Power supply, CPU, graphics card) If the graphics card fan still makes a lot of noise after cleaning it, you can remove the graphics card and go to the computer store to find a radiator or fan for the graphics card and replace it.
Solution: If the sound comes and goes, it is because there is too much dust. Take it apart to see if it is the fan of the power supply, the CPU or the graphics card that is making noise. Clean the dust and reinstall the corresponding fan. Engine oil will do.
You need to remove all accessories, clean them, tighten all the screws on the motherboard, reinstall the hardware, or replace the chassis.
Close the cover on the side of the main case, and then screw on the screws just now. At this time, plug in the wires of the main case, the mouse and keyboard display, and try to turn it on. You can find that the sound will be smaller. a lot of.
The lubricating oil of a certain fan in the chassis has solidified, making the fan difficult to operate. After running for a period of time, the temperature rises, and the sound automatically disappears or becomes quieter. .
The reason why the host makes a loud sound when the computer is turned on: It may be caused by the CPU or the power supply fan. It is very likely that the fan has too much dust, or the fan is broken.
Why does the computer sound loud when it is turned on? Because it is winter and the lubricating oil in the fan has dried up, causing the computer to make a loud sound when turned on. Just wait a while. You can add some lubricating oil such as sewing machine oil.
The best way to solve this problem is to enhance computer cooling, such as adding a radiator and using efficient heat dissipation materials. Corresponding settings: Set the computer fan operating mode to "silent mode" or similar mode to reduce the noise when the fan is working.
Elimination of fan noise Power supply fan and CPU fan noise are the main noise sources. The problem of power supply fan noise is relatively easy to solve. Just buy a silent power supply.
It may be that your fan heat sink is blocked by dust or there is too much sludge in the fan shaft, causing the fan to sound very loud. You need to disassemble the computer and clean the cooling fan or sludge. In addition, you can also check whether the program configuration running on the computer is too high, causing the notebook to become hot.
