Is the bellows of the assembly machine very loud?

Generally speaking, the sound emitted by the computer during normal operation is very small, in addition to the sound of the hard disk reading and writing data, the main sound is the sound of the cooling fan, especially the sound emitted by the switching power supply fan. After long-term use, some switching power supplies will produce some noise when working, mainly due to the poor rotation of the power supply fan. There are many reasons for the noise caused by the poor rotation of the power supply fan, which are mainly concentrated in the following aspects:

The axial deviation of the fan motor bearing sleeve causes the fan blade to be stuck or rubbed and issued"Sudden protrusions"sounds.

The fan motor bearings are loose, causing the blades to emit as they rotate"Buzz"sounds.

The fan motor moves axially, and due to the wear of the gasket, the axial void increases, and it is emitted after powering on"Sudden protrusions"sounds.

Inferior lubricating oil is used in the fan motor bearing, which is easy to condense with the dust entering the fan bearing when the ambient temperature is low, which increases the resistance of the motor to rotate and makes the motor emitted"Buzz"sounds.

If the fan is not working properly, it is possible to burn the motor after a long time, causing damage to the entire switching power supply. In view of the above reasons for the sound emitted by the power supply fan, the following maintenance work is usually required.

The power box is the easiest place to collect dust, if the power supply fan makes a loud noise, generally remove the fan every six months, clean the dust and add some lubricating oil, and carry out simple maintenance. Since the power supply fan is sealed in the power box, it is not easy to disassemble, so you must pay attention to the operation method.

Won't be very loud It's not that your fan has something card.

The fan is dirty, clean it up, add some lubricating oil to the fan, and I'll help you deal with it in Beijing.

There is no way to judge such a description.

I can only say that if it is big all the time.

It could be that there is a problem with the fan.

It can be sent to the repair station for testing. If only a little bigger.

Then it was quiet, and after a while it was loud.

That's normal.

Now the fans of laptops are temperature controlled.

Look at the temperature of your notebook, and I'll help you again.

First check whether the CPU fan is working normally, whether it is installed correctly, whether the noise is very high, whether there is too much dust resulting in insufficient heat dissipation, it is best to touch the heat sink of the fan with your hands to feel whether the temperature is too hot, (the above CPU with the original fan at 20-30C degrees at room temperature is more than 45 degrees, after 10 minutes of use, it is above 60 degrees, the sub-class CPU is recommended to replace the all-copper fan, if the noise is very loud, it is because it is not the original fan The speed is too high, The speed of the original fan is generally around 2200 minutes, and the board of the original Intel 915 can be reduced to 1800 rpm after upgrading the BIOS, many people say that it is a tractor).

There is a fan running in the main unit to cool down, and the construction of the case and the quality of the fan will be the main cause of the noise: if the case is not soundproofed well or the fan quality is poor, the sound will be loud. Some cases have two openings for air circulation, so the sound will be louder.

The most important thing is the quality of the fan. Inferior fans are always buzzing, and if they are not installed well, it will be even worse. Solution: Replace the fan with a new one or oil the fan for makeshift use (sewing machine oil is best, bicycle oil is also available).

Whether the chassis is placed smoothly or not, many of the chassis sounds are resonance.

You can disable the fan. Mine is also an assembly machine, and it's been disabled for more than half a year, it's okay, but it's good to accept it in the summer and not to be disabled. I can't change the fan, and that's my problem

It's possible that your fan isn't installed securely!

Also, the quality of your fan is not very good!

Or it's a problem with the chassis.

No, the noise is mainly in the hard disk and power supply, you can choose a better power supply, such as an active wide power supply.

No, looking at the fans, some are loud, some are quiet. The most important thing is that the heat dissipation is OK.

The loud sound is mainly because the CPU fan is ringing, you can clean up the dust on the fan or simply change it to a new fan, my computer is a new one, and now the sound is much quieter.

The chassis is mainly fans and hard drives.

Fan, dusty one, clean it up, or replace it with a new low-noise fan.

Hard disk,This belongs to the hard wound,But fortunately, the sound is not very loud,It's within the tolerable range.。

Replace all the fans.

Not much.

The main reason is the fan, which should be removed from the ash, and it will be fine after cleaning.

The CPU fan, and the power supply fan will be like this after a long time, you remove it and clean it up, otherwise it won't be particularly loud if you replace it with a new one.

Start slowly, use the optimization master to optimize the startup item, and add some oil to the fan when the sound sounds

Clean the hardware with alcohol, and tighten the screws if it still rings, and the hard disk drive is not tightened.

This is mainly because of the hardware problem, maybe the configuration was not done at that time!

Is it **loud? Fan? Mainboard? Hard disk?

Top dog. There is no way to judge such a description. I can only say that if it is big all the time.

It could be that there is a problem with the fan. It can be sent to the repair station for testing. If only a little bigger.

Then it was quiet, and after a while it was loud. That's normal. Now the fans of laptops are temperature controlled.

Too much dust, I recommend cleaning it up.

That's the CPU fan ringing Intel's fans, some of which are like this.

It should be that the screws of the fan or hard drive are loose, you open the case and check it.

Hello! Psoriasis is hereditary, and there is a certain chance that psoriasis will be inherited. In general, if both parents are psoriasis patients, the incidence of children is 50 66; If only one parent is psoriasis, the incidence is about the same.

Psoriasis is now recognized as hereditary, which is confirmed by three aspects of research: First, there are the same number of patients with clinical manifestations and there are psoriasis patients in their families, i.e. genetic genealogy investigations. According to domestic and international surveys, about 10%-30% of patients have a family history of disease

Among the 943 patients surveyed in the long-term follow-up survey, 279 patients had a family history of disease, accounting for 32 people with three consecutive generations of disease, and 8 out of 25 people with blood relations in one family of three generations, but such families are very rare after all. The second is to investigate and study the incidence of psoriasis in twins. The third is the study of white blood cell blood type, which also proves that psoriasis has a genetic factor.

The earliest is Sunday night, usually in the early hours of Monday morning. I usually go to Polar Shadow, which is the fastest and has a lot of subtitles.

The motherboard battery is dead, are you not able to turn on directly without pressing dlete? If so, just change the battery, change the battery, you don't have to repeat the settings, after you set it, have you saved it?

Press f10 and then y to save and launch.

When the CMOS battery dies, change the battery and then change the time in the BIOS.

If there is dust in the fan, it is recommended to sweep the fan away from the dust and lubricate the core.

I heard that Intel's CPUs are like this, and the Pentium CPU I installed is the same as your situation, and the box buzzes when it is just started, and the sound disappears after 1-2 minutes after entering the desktop, I don't know if it's normal.

Check which fan is to adjust it, and if it doesn't work, change the fan.
