How to solve the problem of the host power fan making noise when turning on the computer?

Oh, it seems that a lot of dust has accumulated inside because it has been used for too long without good maintenance. The solution is to use a brush to clean and add some lubricant for maintenance. Remember to keep the word count under 135 words.

It’s actually very easy to remove. Just take off a few screws on it. But you have to remove your motherboard first. Be careful when removing the data cable. Don’t use force and gently grasp the socket. and motherboard power socket. Also remove your network card and other hardware one by one, and then remove the motherboard. The removed motherboard should be placed on top of a book to prevent damage to the circuits under the motherboard. Unplug the power supply again. The power cord is at the back of the chassis. After removing it, remove the back cover of the power supply. The fan can also be easily removed. After removing the fan, dust and oil it. After installation, be sure to be careful not to install the power supply fan backwards, as this will not work.

After success, install the motherboard, data cable, network card and other equipment one by one.

No matter what type of lubricant is used, as long as it can provide appropriate lubrication effect. If you still hear noise after applying lube, don't worry, just give the fan a few more turns. In addition, you can also consider adding some lubricant to the CPU fan.

My power supply fan makes a very loud sound when I turn on my computer. Is there any solution?

Clean computer fan

Before solving the fan noise problem, please confirm whether the noise comes from the graphics card fan, or the CPU or power supply fan.

If you are sure that the power supply fan is noisy, please do as follows

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. First, turn on the power (be sure to cut off the power, the voltage is very high and dangerous), then take out the fan and carefully remove the sticker on the back of the fan.

If there is a small hole above, you can try to drip a small amount of lubricating oil (such as sewing machine oil or watch oil), but be careful not to drip too much to avoid the oil from overflowing due to the rotation of the fan. Finally, just put a sticker on it.

If there is no oil delivery hole on the back of the fan, you can pay attention to whether there is a larger round soft plug in the center of the back. Use a needle to hook out the plug, and then pull out the fan rotor (including the metal rod of the fan) to clean it. Apply some solid lubricant to the metal rod, and then apply lubricant to the recessed parts at both ends of the stator (the part with the coils on it). After installing the stator, turn it a few times to distribute the lubricant evenly. Finally, install the plug and stick on the sticker to complete the operation.

Note

Remove the sticker and apply oil. Please make sure the back of the fan is clean, otherwise the sticker will not stick

Apply the right amount of oil, don’t apply too much

Attachment

Some fans (such as graphics cards) use magnetic levitation technology and cannot be lubricated. This kind of fan noise is usually caused by physical collision, such as poor contact between the fan power cord and the fan.
