What s the reason for the noisy power supply of the new computer? Please help the little brother tak

1.It's the sound of the fan in the case, take the fan off and add some lubricating oil may be fine immediately;

2.Because your computer's fan is assembled with your CPU at the time of installation, it is not synchronized at startup, but it has no effect on your computer;

3.The new computer has a high configuration, and the corresponding heat dissipation demand is also large, so the movement of the fan will be relatively large, which may be normal;

4.It is possible that the "eccentricity" of the fan's blades is the main reason for the high noise. High-quality fans, the center of gravity of the fan blades is on the axis, the operation is very stable, the noise is very small, and the inferior fans, there is often a certain deviation, the center of gravity of the fan blades does not cause "eccentricity" on the axis, such a fan rotates, it is equivalent to an oscillator (the oscillator is to add an eccentric wheel on the motor shaft), with the use of time, the noise will be very large, so it needs to be replaced;

The above are a few points of view, please advise if it is inappropriate!

It shouldn't be a matter of dust when you just bought it.

Ken can be vibration or excessive current.

Cushioning and shockproofing: For the power supply, the location that needs to be shockproof is not only the connection between the fan and the power supply, but also the connection between the power supply and the chassis.

Prevent high current surge: If the user's power supply noise is caused by the high current at the moment of power on, you can install a filter or switch to a better quality power supply to prevent the noise caused by high current surge. You can also buy some smart power outlets with filter functions to connect to the host computer to ensure that the computer power supply is not disturbed by external currents.

From) or the silent power fan can be replaced.

Personally, I think it should be a matter of shock.

What brand of power supply What embryo machine.

In general, when the computer is just turned on, the power supply fan rotates unevenly (especially if the power supply has been used for a period of time), resulting in high noise. Wait until it runs for a few minutes, and it will be better when the lubrication is sufficient.

It is recommended not to shoot the chassis, noise is a trivial matter, the hard disk is most afraid of vibration, and it will be troublesome if you don't shoot a bad road.

The easy way to do this is to turn on the power (if it is already insured) and replace it with a better fan. Or open the adhesive tape on the back and dot a little sewing oil.

Clean up the dust, fill the fan with some oil, and if it doesn't work, just change to a fan of the same specification.

It shouldn't make a big difference.

If the fan is off, change the fan or repair it.

First, determine if it is a power supply fan.

Newly bought power supply, to the seller for repair or replacement.

1. There are three situations in which the sizzling sound is made:

1. The mains voltage is too high, or the power supply is small, and the load is too heavy. If the mains voltage is too high, another voltage regulator can be added; If the hardware power consumption in the host is large, this power supply cannot be undertaken, so change to a power supply with high power.

2. The inductance coil and transformer in the power supply will not affect the use of the inductor noise caused by poor impregnation or poor design, and there is no good way to solve it except for replacement.

3. The inferior capacitor in the power supply, or the pulp capacitor will produce a sizzling sound after being energized, and replace the problematic capacitor.

Second, the power supply fan rings loudly.

1. Remove the power supply fan after shutting down, check whether the fan blades are deformed or broken, and trim the deformed and broken fan blades; If normal, use a brush or cotton cloth to dust the fan.

2. Go to the center of the back of the fan, uncover the plastic oil seal, put a little antifreeze lubricating oil or sewing machine oil on the roller, and seal it.

3. Put the fan on as it is, and turn it on for trial.

4. Inferior fans, replace them with new fans.

Hurry up to repair the computer to take a look, the power supply problem is not a trivial matter, my power supply squeaked a few days ago, sometimes there are sparks, very dangerous.

Are you sure it's the fan sound on the power supply? Some CPUs are intelligently temperature controlled, and when running large programs, the network speed will be increased, and there will be sound. Most desktop computers like Lenovo are like this.

Power supply, graphics card, CPU fan sound is very loud,,If the system resources are used the larger the fan turns faster,,Yours is the assembly machine,,It's normal for the sound to be louder,,The sound of the brand machine can be smaller,,You listen carefully,,When you start the computer, the sound is very loud and then slowly lowers so that it is normal,,Don't be very big all the time,It's not normal,,The sound is loud because your power supply is too big,,The faster the fan turns,,Some cases are not reasonably designed,,The air in the inside can not be turned out, and the sound will be loud,,It's no problem if the sound of rotation is big,It's a little noisy,,You can't hear it after listening to it for a while,,6800 yuan of my own computer is also like this,,I used to think it was very loud,Now I can't feel it,,The more powerful the fan, the louder the sound in theory。
