1. When the computer is turned on, the fan is running at full speed, so the sound will be very loud, but when it is running normally, the speed will be Slow down and your voice will become softer. Because today's motherboards are automatically controlled by the BIOS and automatically adjust the fan speed according to the temperature.
2. The reason why the computer keeps beeping when it is turned on is that the fan or hard disk has not been cleaned for a long time. Fan sound: Replace the fan or remove dust. There are power supply fans and CPU fans. Hard drive: If the hard drive has been used for too long, there will be sound when reading the hard drive. If the sound is too loud, it means that your hard drive is about to break.
3. It may be that the lubricating oil of the fan has aged over time or the fan has not been cleaned for a long time and there is too much dust on it, resulting in a loud friction sound when starting up. You can clean the dust on the fan and add lubricating oil again. Sometimes it is also related to the quality of the fan. If it does not affect the use, there is no problem.
4. The reason why the computer always buzzes when it is turned on is because the computer CPU fan, the dust on the power supply fan is too thick, and the fan bearings are aging, which makes the computer host loud. The reason is that as the computer is used for a long time, a lot of dust will accumulate on the CPU cooling fan and the power supply fan, which hinders the normal rotation of the fan and produces noise.
5. This situation usually occurs in the first few minutes of startup. In this case, there will be no noise during the summer when temperatures are higher. In addition, if there is too little oil in the fan and insufficient lubrication, the noise will be loud. Sometimes it sounds like a tractor when it gets louder. At this time, just disconnect the power supply and refuel the fan.
1. Poor computer heat dissipation may lead to increased fan noise. Make sure the heat sink and fins inside the computer are not blocked or have accumulated dust. Replace the computer motherboard. If the above methods do not resolve the fan noise issue, there may be a hardware issue. Try replacing the computer motherboard.
2. The computer starts up with a loud sound. The sound from the CPU fan. The sound from the graphics card fan. The sound from the hard drive. To solve the problem, open the case and listen carefully to the source of the sound. If it is 2, congratulations. The solution is very simple. Remove the fan. Clean the dust, remove the fan seal, add some oil, and then seal the seal again.
3. The fan often changes the speed according to the CPU power to reduce the temperature. When the computer is turned on, the power is high, so the speed is high and the sound is loud. Sometimes it is also related to the quality of the fan. If it does not affect the use, there is no problem.
4. In winter, the ambient temperature is low. Generally, the sound of the power supply fan is 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. The reason for the louder fan sound may also be due to the accumulation of dust.
5. 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 fan will be detected when the computer 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.
The reason why the computer makes a loud sound when it starts up: 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 broken.
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 also louder. The above is normal unless the sound is extremely loud! It may be caused by the CPU or power supply fan.
Then check whether the operating environment temperature is low, the lubricating oil has solidified, or it has been used for too long and the lubrication is not enough, so it is difficult to operate and 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, they automatically adjust the fan speed based on the temperature.
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 there is no sound or the sound becomes smaller automatically. .
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 make a loud sound 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 it is turned on. Just wait a while. You can add some lubricating oil such as sewing machine oil.
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.
I don’t know if the sound you are talking about refers to the sound inside the computer host or the sound from the speakers. If it is inside the host, it is more common.
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, they automatically adjust the fan speed based on the temperature.
There is a problem with one of the fans (including the power supply fan) in your computer. It must have made a loud noise when it was turned on, but it got better later. It was because the fan bearing was out of oil. The gap between the bearing and the outer sleeve was very tight when it was first turned on, causing the sound to be loud. After turning for a period of time, the gap was due to thermal expansion and contraction. The louder the sound, the quieter it becomes.
Reason: Because the system will detect the hardware when it starts. The fan will be detected when the computer 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.
It is possible that the computer's fan needs to be accelerated to bring the temperature inside the computer down 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.
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 to be loud. Condition.
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.
The above is the detailed content of The fan sounds loud when the computer is turned on. For more information, please follow other related articles on the PHP Chinese website!
