The case is loud when it turns on, and it is slightly better when it enters the system 10

This is a new technology, and it's a smart fan that's unique right now, and when he starts up, the speed of the fan goes up, and it goes into the system, because the CPU station uses less heat, and the heat isn't so big, and the fan goes down in a few revolutions.

Also, your hard drive is aging, which can cause the machine to be loud.

You double-check the many reasons.

It's cold, a lot of machines like this, don't worry.

At the same time, you can also change to a new fan.

It's cold, and the machine needs to be hot to be normal. It's not a big deal. Rest assured, so is my machine. It's still "screaming". It's that my fan is old and I don't have the money to buy a new one. Just enough is enough.

Try a different fan, the hard drive will not make too much noise under normal circumstances.

There is a problem with the power supply fan, it is recommended to remove the dust inside.

It's okay, don't worry!

Because every time the computer is turned on, the computer needs to detect the temperature, and only by detecting the temperature can the performance of the CPU and graphics card be guaranteed!

Ha,,It's all the same...

Generally, if the sound is loud, it is emitted by the power supply fan,,, as long as you look at the power supply fan, it is almost the same.

It could be the sound of the power supply fan.

It's cold, a lot of machines are like this, and so is mine.

Generally, it should be the sound of the fan, ignore it, and it will be fine when it gets hot for a while.

Discrete graphics card, maybe graphics card fan, power supply, maybe power supply, maybe hard disk.

You can take the graphics card off and boot it up.

After taking the hard drive off, boot it up and see.

If it doesn't sound, it's the pull of the power supply, and it is possible that the capacitance of the power supply is bone.

It's the same with my computer, and my friend said it's good for heat dissipation, hehe.

I don't know, I've opened it once, I can't press it, and I look for GF to press it.

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.

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.

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.

Analysis: CPU fan issue.

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 oil.

Workaround: 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.

When the machine is first turned on, the fan is running at full speed, and the natural noise will be louder. Enter the system, the power management software in the system works, manages the fan speed, adjusts the fan speed according to the temperature in the machine, the fan speed is reduced, and the noise is smaller.
