Please help me look at the problem of the computer turning on loudly

It should be the noise caused by fan friction.

It is advisable to open the case and listen to whether it is a CPU fan or a power supply fan (if there is a discrete graphics card fan, also listen).

After determining, after removing the fan, add a small amount of lubricating oil in the shaft, and the current fan quality is average ** is also cheap The ordinary point is about 30 RMB, if you are lazy to disassemble, you can directly buy one to replace it If it is a power fan, then disassemble it 30 minutes can be done If you have no disassembly experience, find a computer company Even if you assemble a computer, there is a 1-year warranty.

If it is not maintained in time, the fan will stop working due to long-term friction, and the consequence is that there is a problem with heat dissipation, resulting in the blue screen of death, and the most serious is the damage to the accessories.

Fan speed problem: just turn on the maximum speed After that, enter the system driver control to reduce the fan speed to a certain extent, theoretically, whether it is turned on or after, it should not be loud, it may be that your case is loose and resonate, or the room temperature is too low.

That CPU fan is easy to remove and oil. I just oiled last night... I can't help it... The CPU fan speed is only a little over 400 rpm... Everything works fine now.

It's normal for the fan to go off in winter.

Because the weather is dry, the lubricating oil cures, and after the running end time, the temperature is high, and the lubricating oil melts.

Of course, your machine has not been bought for a long time, and this problem has occurred, and the quality is definitely not very good, but fortunately, the fan is only a few dozen dollars, if you can't bear it, you can consider changing it.

1.Vibration is the source of sound.

2.The only thing that makes sound from the computer is the fan and the hard drive. Fans have CPU fan, power supply fan, graphics card fan, 3These things are not fixed well and will make a lot of noise.

4.Generally, the problem is the CPU fan (loose or less oil, cold in winter is also a reason), the greater the load on the computer, the higher the CPU temperature, the higher the fan voltage, the faster it turns, the computer has just started, it may suddenly power on, the voltage is high, the speed is fast, plus the fan you are talking about is not good, the sound is louder. This will not affect the normal use of the computer (if the computer does not restart frequently).

5.Check if there is any looseness, if there is one, you can fix it, if you are not at ease, you can buy a fan to replace it. Inexpensive

2.Your computer has not been equipped for a long time, I don't know how to configure, and it will not be broken in general, so you don't have to worry. But if you think it's louder and louder, there's a problem. It's best to find someone who can help you with a computer. Anyway, the warranty period has not arrived. Good luck..

Under normal circumstances, when the computer is turned on, the power consumption is large, which causes the CPU fan, power supply fan, and case fan to rotate at high speed. You might change a little better power supply with a case plus CPU fans to get you the best results. Needless to say, there are all upstairs, I wish you a speedy release of your troubles.

The Rookie King

The shaft of each fan should be lubricated with a low-temperature resistant lubricating oil. 1.In this season, the sound of the computer is particularly loud when it is turned on, which is generally cold weather, causing the oil in the CPU fan shaft or ball to freeze, or the power supply fan fan shaft or ball oil to freeze, making the computer boot sound particularly loud, generally after the computer runs for a period of time, the computer heats up, the oil melts, and the sound will be normal.

This usually happens in winter.

2.If the above statement is excluded, it may be because there is too much dust in the computer, and there is dirt on the fan, which increases the fan resistance, so that the fan cannot operate normally, and the computer sound is particularly loud.

3.There is a problem with one of the fans on your computer, including the power supply fan. It must be that the start-up sound is loud, and it will be good slowly, because the fan bearing is out of oil, and the gap between the bearing and the outer sleeve is very tight when it is just turned on, resulting in a very loud sound, and after rotating for a period of time, the sound will be small due to the increase in the gap between thermal expansion and cold contraction.

The solution is to open the chassis and find the loud fan to add some oil to the bearing, but it won't take long, and the second is to replace it with a new fan.

Loud sounds are generally caused by fans, power supply fans, CPU fans, and graphics card fans (not if it's an integrated graphics card). Take a look at whether each fan is working properly and listen to which fan is working noisily. Especially the fan of the power supply.

If any fan is noisy, you need to consider replacing it. My previous computer was basically the same as yours, starting like a tractor. It's just that the power supply fan is broken, and it doesn't make so much noise when it restarts, because the computer has already started, and the sound is loud when it is just started.

Clean the graphics card, power supply, fans on the motherboard, there may be too much dust. Note if there is a line stuck. Or the screws are loose. Generally, the fan of the power supply will be louder, so change the power supply.

False: That's that your motherboard and power supply don't match very well and there is a power supply issue

But it's okay A lot of computers turn on a little bit

If you play large 3d games, it will also ring load problems

Power supply fan and CPU fan noise are the main sources of noise. The problem of power supply fan noise is relatively easy to solve, just buy a silent power supply.

The noise reduction method of the power supply fan is generally to reduce the fan speed, and if the CPU fan reduces the speed, it will inevitably affect the heat dissipation of the CPU, so the CPU noise reduction method mainly lies in the lubrication of the bearing and the structural design of the fan blade. Due to the high speed of the CPU fan, it is a bit difficult for the CPU fan noise level to reach the level of a silent power supply, but we still try to choose a fan with a silent function. Of course, it's also a good idea to add some lubricant to the fan bearings yourself.

The noise generated by the graphics card fan and the case fan is relatively small, but too many case fans installed in the case can also increase the noise of the computer. Installing as few fans as possible is an effective way to reduce noise, but for those computers that must have multiple case fans, you can choose some case fans with large diameters and low speeds.

Remove the fan, use a needle or something else, dip the lubricating oil, and finally dip the oil with a needle, not more, drop it in the hole in the middle of the fan, turn the fan, the oil can not drop more, two drops can be. The problem is solved.

This should belong to the landlord, the fan in your host is ringing, you can try to put the case in a different way!

Alternatively, you can open the case and take out the fan and drip some vegetable oil on the fan.

Here's an easy way to identify what's ringing:

Turn off the machine first, then open the side panel of the case, and press the handle on the CPU fan blade (the purpose is not to let it turn) Don't be afraid, only touch the fan blade and the power will not be able to power you, turn on and listen for 5 seconds, and see if it still rings?

If it still rings, repeat the action just now, turn off the device, press your hand on the fan blade of the graphics card, and also turn on and listen for 5 seconds.

If it still rings, and there is no other fan to press, it is a power fan, go and change the power supply or take the power supply to the repairman to change the fan.

Be careful not to press the fan for too long. Don't push too hard, it will damage the hardware, and don't press it when the fan is spinning, it will damage your fingers.

I don't know if you mean the sound inside the computer or the speaker? If it's inside the host, that's more common. The main ones are:

1. CPU fan: The current fan has the speed regulation function, and the speed of the fan is the highest when it is just turned on, so the sound is also the largest, and there is not much sound when the speed drops to the normal value in about 5 seconds after the start-up;

2. The internal fans of the host (including power supply fans, graphics card fans, CPU fans, etc.) have dust or lack of oil, and the noise is very high when the ruler is just rotated.

3、If there is noise when the speaker is turned on,It's not easy to do,It can only be solved by turning on the host first and then turning on the speaker。

Check it out for yourself, you can disassemble the case to see which fan has a problem.
