Can the computer power supply fan continue to be used when it is aged?

I used to work as a service engineer at Lenovo, and in your case, the machine is still under warranty and it is not recommended to disassemble the power supply.

The cause of the failure is due to the noise caused by the wear and tear of the power supply fan, as long as the power supply dissipates heat normally and does not affect the use of the computer, you can continue to use it. If you are not at ease, you can call Lenovo's service ** consultation, or even take the machine to the local service station for testing or free power replacement.

If you replace a power supply from another brand, Lenovo doesn't warrant the power supply, but you can rest assured that other parts are still covered by the warranty.

Replace it, mine used to be, and then it will automatically restart or shut down, and finally burn the power supply, and the fan is very cheap to change it, more than ten yuan!

It is possible that there is too much dust in the power supply. Or maybe the power fan is really old.

I suggest you change one.!Other brands don't matter...

Because many people buy computers and assemble them themselves!

The disadvantage is that after the fan burns out, the computer will have a burning smell after it has been turned on for a long time!

There's not much of a problem with this.,It's just a little noisy.,Mine too.,And I just bought it.。。。

As long as you don't crash or restart, you don't need to change it because your computer is still safe.

Clean up the dust inside and don't take it apart.

It is also possible to drop a few dots of oil (sewing machine oil).

If this is still the case, change the power supply, Lenovo machine power supply, 1 year warranty, buy a more than 100 points of Huntkey, no problem.

It should be no problem to clean up the dust, you can use it!!

It is not recommended to use a problematic power supply.

As long as it is used normally, there is no problem if it does not affect the use.

That one won't turn after a while, it will automatically freeze, and you can buy a new fan, but it's more cumbersome to change.

It is recommended to buy a power supply, a few dozen dollars are enough.

The power supply is not stable and unstable, I have used the 10 yuan power supply for 3 years, the fan is not turning, and I continue to use it, and there is no impact.

It can still be used for the time being. As long as you use the process does not crash. If there are no problems, it would be good. It's just noisy.

A little. Your fan. It's not aging. It's just that the oil is gone. You can also contact your local association.

I would like to consult a dealer. Lenovo is a nationwide warranty.

Lenovo's if you can go to the after-sales service within the warranty period.

Summary. 1. First, check whether there is a problem with the memory module.

Unplug the memory module, test the computer boot one by one, if the boot fan will not turn and stop, it is a problem with the memory module, in this case, you can replace the memory module with a new one.

2. Secondly, check whether the power supply is working normally.

The detection method is the replacement method, and the test is carried out with a new power supply, and if there is no problem with the new power supply, it is a power supply problem.

The computer power supply fan turns off and the power supply is not broken.

Hope it helps.

The power supply is normal. The memory module is normal.

I'll take a look. Thank you.

Finally, repair or replace the motherboard. If it still can't be solved, it is likely to be a problem with the motherboard. If it is not serious, the capacitor next to the CPU in the motherboard is broken, and the CPU on the motherboard is also broken, so you can only find a professional repair organization to repair or replace the motherboard with a new one.

Hope it helps.

If there is a problem with the fan, the CPU heat dissipation will not be normal, the CPU temperature will get higher and higher, the system will run slower, and there may be a crash. More serious will burn out the CPU.

Fan it plays a role in the operation of the whole system, its role is the full-time nanny of the CPU, specifically for it to cool and dissipate, its normal work is directly related to the stability of the system of life and death, generally we usually match the fan service life is about 2 3 years, if you do not timely point lubricating oil or clean up the dust on the fan blades, it will make it sick operation, so that the cooling effect is greatly reduced, the symptoms are: the noise is significantly increased, the speed is too low, and even leads to a black screen of the computer, the system crashes, CPU scrapping.

The CPU heat dissipation is not good, it will often crash, and the sound will be very loud and noisy.

1. Loud noise.

It's uncomfortable to use.

2. The vibration is still damaging to the electronic devices.

3. It's very troublesome to suddenly not be able to turn around for a day.

When you turn on the computer, press del into the BIOS, and set the fan to silent mode.

It should be pointed out that the landlord, have you bought a more high-end silent power supply? Is the room where you use your computer not very hot? Does your computer not consume much power? Does your computer case have its own case fan, so the internal temperature of the case is not high?

Some high-end silent power supplies, there is a temperature sensor inside the power supply. When the power supply temperature is not high, the power supply fan will stop to achieve a silent effect. In this case, there is no problem with the power supply fan not turning.

But if the landlord buys an ordinary power supply, and the landlord's answer to my question above is "no", then it is certain that the landlord's power fan is broken. The power supply can burn out at any time due to overheating. The landlord should hurry up and repair the power supply, or go buy a new one.

If it is a little later, the motherboard, hard disk and other parts are likely to burn out.

Reasons why the exhaust fan of the computer main chassis does not rotate:

1: The power cord of the exhaust fan is burned;

2: The wind wheel of the exhaust fan is stuck, causing the motor to burn out.

Solution: Remove the non-rotating exhaust fan and buy a new one.

The power supply is a very important place, if your power supply fan does not rotate, it will affect the heat dissipation inside, and then it will affect your voltage, your power supply can smell burnt, it may be burned something, I suggest you change the power supply, if you just change the CPU fan, it may be usable, but the things in you have been burned, it is likely to cause the voltage to be unstable, if you burn the motherboard or something else, it will be a big loss Please solve the power supply problem first. The easiest way to check is to replace it, which is to find another computer, install your power supply on another computer, and then you can judge whether your power supply is faulty. If there is no fault, replace the other accessories one by one, and you can find out the problem.
