When the computer is working, the main engine fan is sometimes very loud, what is going on, how to s

The higher the CPU use, the higher the temperature, of course, the fan should be faster, and the noise will be louder.

The lubricating effect of the hinge of the power supply, discrete graphics card, and CPU fan becomes worse, and it heats up after a period of time after being turned on, so that the lubricating oil temperature rises, and the original lubrication effect is restored, and then it will not be too loud. The shaft of each fan should be lubricated with a low-temperature resistant lubricating oil. 1. When the computer is turned on, the sound is particularly loud, the oil in the CPU fan shaft or ball is frozen, or the oil in the power supply fan shaft or ball is frozen, which makes 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. Repair House" 乄 ip worm sincerely serve you.

The general home computer needs 4-5 months to clean the dust on it, open the lid of the case, you can see, unplug the fan, the four screws can be removed. Use a soft-bristled brush to brush off dust. If the fan is a year and a half old, it should be replaced.

You can buy it for 15 yuan in the computer city. (If you change it professionally, you can clean up the dust of the heatsink by the way) Presumably this is the reason why your computer's fan rings! You can try it!

The ultimate cause of my computer's noise is that background programs are doing the trick. This background program is not ordinary, and it cannot be solved by reinstalling the system. Finally, it is completely solved by deleting the previous system after flashing the BIOS.

It took a whole week to clean the fan, mass production partition, and reinstall the system, and finally there was no way, so I thought of brushing the BIOS.

The sound of the main computer case of the subject computer should be mechanical. You can first check the operation of each cooling fan. Observe the mechanical sound of the fan.

Then, deal with the problem cooling fan.

You can also use shock-absorbing glue to paste it on the chassis seal plate to achieve the effect of shock absorption and noise reduction.

The fan in the host unit is aging. The host includes power supply fans, CPU fans, graphics card fans, and power supply fans. Such issues can clean up the power supply fan dust.

Prepare the oil and toothpicks, unload the power supply from the top of the chassis, then open the housing of the power supply and remove the fan. Find the place where the dust is sniping, use a gentle brush to clean the dirty place, after the cleaning is completed, there will generally be a label on the front of the fan, open the label, and use a toothpick to dip the oil on the bearing under the label. Then glue the label back, restore the power supply, and put it back on.

Note: a. When oiling the bearing, the amount of oil should be appropriate. b. When filling the fan with oil, use special oil or high-quality sewing machine oil, and accelerate the wear of one side of the bearing. Many of today's silent power fans have been rigorously tested to reduce noise, so you can consider replacing the silent power fans.

Generally, the noise of the case is caused by fan resonance, and in most cases, the graphics card is more so

If the fan has an abnormal sound, try to apply some lubricating oil first, if it still rings, change the fan, the fan shaft is not in the center will cause loud noise, this can not be repaired, only replaced.

1. [The computer boots up and the host makes a very loud sound] The fan sounds! If you are short of oil, you can add 3-5 drops of sewing machine oil. It does not affect the boot and display.

2. [And often the red light under the power light is not on] The red light under the power light is the hard disk light, and it is conditional that it is not lit and bright: only the hard disk reads and writes it! If it's always on, it's a problem!

Three [can't connect with the monitor what's going on]: Make sure the computer is started, no display, check:

1. Press the power button for about 10 seconds and listen to the "drip" sound of the computer starting, if you can't hear it, it won't start, and the monitor will definitely have no signal.

2 memory gold fingers with an eraser from the new fit.

3. By the way, move the CPU socket and graphics card, and wipe the gold finger from the new installation, 4. The peripherals are also checked.

Generally, the hard disk is ringing, it is the sound of starting the seeker, this fault is generally caused by too much wear and tear of the hard disk, or the memory is too small, open the side cover, press and hold the CPU fan for a short time, it is generally the sound of the hard disk, I have also had similar symptoms, as long as you change to a larger memory, so that the time to access the hard disk is as little as possible, it is OK.

Take your case cover down and listen carefully to see what the reason is, it should be your CPU fan.

Take it down and refuel it with some oil!

Jianyi unplugged all the wires, only connected to the motherboard power supply, don't connect the hard disk and optical drive, if it doesn't ring, take one and turn it on to see if it's a stupid way to sound haha.

Because many fans now use grease, the viscosity of the grease is high at low temperatures, and the friction force is large, so the sound is loud, which generally appears when the machine is just turned on.

As the computer runs, the temperature gradually rises (similar to the effect of turning the computer off and on twice), and the lubricating rib grease begins to slowly soften, the viscosity decreases, and the friction decreases, so the sound will become quieter and quieter.

If it has been loud, it means that the grease is close to curing and can no longer be used, you can solve it by adding oil to the fan, but due to the presence of grease, the effect is not very good, it is best to change the fan.

This solution is applicable to XP Vista Win7 system.

Problem Description]:

Computer noise, fan noise.

Cause Analysis]:

1.The optical drive has an optical disc caused.

2.Hardware failure.

Solution:]:

Solution 1: Check the optical drive.

1.If there is a disc in the optical drive, please take out the optical disc when the optical drive is not in use, otherwise every time you boot up and start up, you will check the peripherals of the optical drive and read the optical disc, 2The vibration and sound of the computer will be relatively loud.

Solution 2: Detect the hardware and fans.

1.The hard disk disk will squeak or click when reading data on the track, as long as the computer is running more frequently than the case of frequent crashes, the hard disk sound is normal, especially the old machine hard disk aging or the sound of the large storage hard disk is louder.

2.If it is the sound of a fan whining, the computer has a temperature control setting, and with the length of computer use and the temperature of the computer, the speed of the host fan, especially the CPU and graphics card fan of the notebook, will change.

In the same way, if it is an old machine, it is recommended to clean the dust of the graphics card fan, CPU fan, and host power supply fan, and if the effect is not obvious, you can appropriately add the special lubricant for the fan or replace it with a new one.

It is recommended that you go to a professional repair shop to clean up the dust from the graphics card fan, CPU fan, and host power supply fan to avoid unnecessary hardware damage.
