The main unit just turned on and it was very loud, what should I do

The sound of booting is only the fan and the hard disk, and if the hard disk is so loud and resonant, it must have been broken a long time ago.

Then it's just the sound of the fan, and you can listen to whether it's the power supply, CPU, or graphics card fan that is loud.

The fan is used for too long, the oil is dry, especially when the machine is turned on, the oil is relatively small, the oil is still cold when it is turned on, the fan friction is too large, and the noise is made.

Disassemble the case, remove the fan, and oil it. I bought my computer for four years and oiled it once in between.

This is very normal, it is possible that when the motherboard is powered on, all fans are running at full performance, and then intelligently adjusted.

It is also possible that there are two of the following situations:

Scenario 1: The CPU fan collides with the wires in the case, causing the fan to make a noise when it starts up.

Solution: Open the case and remove or bypass the wires next to the fan.

Situation 2: The CPU fan is out of oilSolution: Remove the CPU fan.

Place it on the table and carefully peel off the sticker behind the back. Take out the rubber stopper. If you use a small screwdriver, it's easy to take out and put in this plug.

Drop a few drops of lube in it.

Put the eraser in place and put the sticker on your back back back to where it came from. If the sticker is no longer sticky, you can use a small amount of glue to stick it.

Turn the fan and let the oil seep in. Once you have the fan installed, when the computer is running for a few seconds, the oil will enter the metal hole and then into the cylinder, and you will notice that the fan is spinning faster and quieter than before. Not only does it make the fan less noisy, but it also makes it last longer.

Suggestion: It's better to replace one, the fan is loud, not only the lack of oil, most of the use time is long, the life is estimated to be gone, his wear is too large, there is loosening, and he will be uneven when he turns.

Hello, the reasons for this are roughly as follows:

First, the computer will be affected by the surrounding temperature to some extent, and the CPU fan is generally monitored on the motherboard. When the temperature is high, the start is fast, and the fan is fast and not fast. The natural sound is quieter.

When the temperature is low, the monitoring will make the fan start faster and the natural sound will be louder.

Second, if a friend said about the fan, after a long time, there is dust, which also affects the rotation of the fan. If the wind debris is on the fan, but the monitoring requires it to turn so fast, it will naturally produce a high load, and the reflection is different in addition to the sound and the heat.

Third, it has something to do with the quality of the fan itself. Some fans are well-made and fine. It turned up without a sound.

Fourth, it has something to do with whether the chassis is good. If the chassis is made of material, the construction is not good. The sound of the fan turning resonates with the case. Of course it would be loud.

The reason for the loud sound is generally on the fan, you can open the case by yourself but recognize it to see if it is a power supply fan or a CPU fan or a graphics card fan, and generally clean up the dust.

Fan problem! When the CPU fan arrives in winter, the temperature is low, so the lubricating oil will be poorly lubricated! You still have to use appliance lubricant on your fan!

It must have been like this at the beginning, and it will be fine after a while, if this is the case, it may be a problem with the fan, or maybe it is a lack of lubricating oil, coupled with the low temperature in winter, which causes lubrication problems. If it's fine for a while after turning it on, don't worry about it, and if it's always like this, it's recommended to refuel the fan or replace it.

My computer is the same, it's very simple, the host has a total of up to three fans, one for the graphics card and one for the CPU! But it's all small, and it's impossible to make a roar, so it's a big fan of the power supply, which is very loud when it's turned on, and it's light again when it enters the system! Change him, or drip some oil on it, and you'll be fine.

The sound generally comes from the fan and the hard disk, and the fan sound ** has CPU fans, graphics card fans, power supply fans, and the sound of the general fan is likely to be caused by the high temperature of the corresponding components. If it's the sound of the hard disk, it's likely that the hard disk is in a very unhealthy state.,Why find some software to detect it.。。。

The fan oil is less, the curing is serious, the weather is cold, the oil resistance is very large at the beginning, the noise is large, and the machine runs for a while, the oil is opened, and the lubrication effect is improved, and the noise is reduced, but you must refuel! Or simply replace the bearing fan!

The cup fan may be out of oil, just go to the computer maintenance point to add some oil, otherwise the card of your fan is not stuck, if not, it means that your fan speed is too fast, because the cup temperature is unstable, the speed of the fan will also change, so after 1 while, it may be that your CPU temperature is unstable, and it will not have any impact on the computer,

The power supply or CPU fan is dusty, just clean it with lubricating oil, and never knock the chassis with electricity in the future, so as not to cause damage.

Let's see if the wired has touched the CPU fan, maybe it's the power supply again, do you change it?

The noise generated by computers is mainly divided into vibration noise, fan noise, etc.

The main components that produce noise are power supplies, CPU fans, graphics card fans, hard disks, optical drives, etc., and the causes of noise are as follows:

1 Too many fans in the chassis.

2 Poor design of the heat sink.

3 The fan has accumulated too much dust.

4 Improper wiring.

5 Vibration noise.

6 Hard disk read and write noise.

7 Optical drive noise.
