The power supply fan makes a loud sound when the computer is turned on

Why is the computer fan so loud?

1. If the computer fan suddenly becomes louder, there are usually several possible reasons: The fan itself is aging or damaged. Computer fans will age and wear after long-term use. Damage to bearings and other components can cause the fan to become louder or vibrate. At this time, the fan needs to be replaced to solve the problem. The radiator is clogged.

2. Fan damage: Computer fans may malfunction due to long-term use or other reasons. If your computer fan's blades, bearings, or motor are damaged, it may become unusually loud. At this time, it is recommended to replace the computer fan.

3. The main reasons for the loud sound of the computer case fan are as follows. The solutions are as follows: Dust blockage: Once the dust on the cooling fan accumulates a lot, it may cause the computer case fan to make loud sound.

4. The rotation of the fan is related to the temperature of the CPU. If the ambient temperature is high, running too many programs or large software will cause the CPU temperature to rise. When the CPU temperature increases, the fan will rotate more frequently. , the sound will be louder.

My computer’s fan makes a loud sound after I turn it on. How can I eliminate it? 5

1. The best way to solve this problem is to enhance computer heat dissipation, 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.

2. To refuel the exhaust fan, buy a bottle of sewing machine oil. If you have peanut oil at home, you can also use this instead. Add oil to the exhaust fan shaft and the groove close to the coil. After applying the oil, soak it for a while before installing it. This will basically solve the problem of loud sound.

3. 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.

4. Hello! How to reduce computer host noise, reduce power supply noise, clean power supply fan dust, first prepare a small bottle of oil and a toothpick, then remove the power supply from the chassis, open the casing of the power supply, remove the fan, and find where the dust collects on the fan blades , clean it up with a soft brush.

5. The computer fan is too loud. Solution: Dust blockage Dust accumulation on the cooling fan is one of the reasons why the computer case fan is noisy. We can first pry open the top interface of the keyboard, use a screwdriver to remove the screws below it, and then remove the keyboard, optical drive, and hard drive according to this, so that you can see the cooling fan.

6. As for the reason why the fan makes a loud sound, there are two possibilities. One is that the fan is loose, and the other is that there is too much dust. You can disassemble the computer host and check whether the fan is loose. It is recommended to remove the fan and clean the dust. If possible, drip a little lubricant, then reinstall the fan and fix it.

The fan sounds loud 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 when it is running normally, 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.

It may be caused by the CPU or power supply fan. It is very likely that the fan has too much dust, or the fan is broken. First open the computer host and check whether the CPU fan is caught or touched by other wires in the chassis. If so, arrange the wires and tie them up to prevent them from touching the fan.

This is because when the weather temperature is not high, the grease in the CPU fan solidifies. 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.

The fan is very loud when I turn on the computer, but it gets better after a while. What is the reason?

1. There is a problem with one of the fans in your computer (including the power supply fan) . It must have made a loud noise when it was turned on, and then it got better gradually. It was because the fan bearing was out of oil. When it was first turned on, the gap between the bearing and the outer sleeve was very tight, causing a loud sound. After it was rotated for a period of time, the gap between the fan bearing and the outer sleeve was tight due to thermal expansion and contraction. The louder the sound, the quieter it becomes.

2. 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. He will have some tests that will not be repeated.

3. It is likely that the computer fan needs to be accelerated to reduce the temperature inside the computer to a suitable level. When the computer is powered on, the use of the processor and other components may increase the temperature, causing the fan to run noisier.

4. The computer fan is loud. This will happen after using it for a long time. However, you must know the reason why the fan sound becomes loud. In many cases, the equipment has not been cleaned. Excessive dust can also cause the fan sound. big situation.

5. So the sound is loud when you first turn it on, and then it becomes quieter. This situation usually occurs within the first few minutes of booting up the computer. In this case, the noise will not appear in summer when the temperature is higher.
