1, open the chassis and see that the CPU fan is covered with dust!
2. When the fan is disassembled, you can see that the fan blades and fins are covered with dust. At this time, you should find a brush to clean up the dust on the heat sink and the dust on the fan blades.
3. Uncover the plastic film at the bottom of the fan. Note: Do not completely uncover, only the bearing (yellow part) is exposed, and it is not easy to stick to it after completely uncovering. At this time, we can see that the bearing is dry and there is no lubricating oil, which is the reason for the noise. (Different fans, different refueling locations)
4. Dip a little engine oil and carefully drop it on the fan bearing.
Note: just three or five drops, not too much, too much will spill out, sticky, but will stick to dust.
In addition, after the oil overflows, the plastic film is not easy to stick.
In addition, each drop of oil will make a fan blade rotate several times, so that the added lubricating oil can be wetted in the bearing.
5. Look carefully and take a close-up. The bearing has been filled with lubricating oil.
6. After adding oil, you will avoid wiping with paper and then stick a plastic film.
At this time, blow a few breaths on the fan blades to see if they can rotate flexibly. If it doesn't turn, it proves that it is still stuck and needs to be lubricated again until it is completely flexible.
Question 2: How to refuel the fan of the computer? What kind of oil should I add? Removed fan. Put it on the table and carefully tear off the sticker on the back. The computer network tribe took out the rubber plug. If you use a small screwdriver, this plug can be easily taken out and inserted. Drop a few drops of lubricating oil like this to cover the rubber and put the sticker on the back back back. If the adhesive is not sticky, you can stick it with a small amount of glue.

Question 4: How to refuel the computer CPU fan? After the computer runs for a period of time, there will be a buzz in the chassis when it is first turned on, and it will return to calm after a few minutes. Most people don't pay much attention to this problem. Some people pat the chassis a few times to reduce the noise, but they don't think so. In fact, this is the performance of CPU fan or power fan lacking oil, which is very unfavorable for the safe operation of the computer. Let's talk about how to refuel the CPU fan to reduce noise: tools/raw materials.

Different refueling positions)

Question 5: How to refuel the computer fan? What kind of oil do you want ~ If you haven't touched the fan, there should be a label on it. When you open the label, you will see a filling hole for filling the kettle. Personally, I think sewing machine oil can be used as a better oil, and of course engine oil can also be used.
Question 6: How to refuel the computer power fan? 1. How to remove the power fan?
To replace the power supply, we must first understand these problems: fan size and fan interface, which can be seen from the inside when the power supply is disassembled. Removing the computer power supply is simple. Just use a Phillips screwdriver to unplug the power supply from the chassis first. When disassembling, pay attention to the power failure, first disconnect all wires between the power supply and the hardware. After taking out the power supply, first remove the four fixing screws on the surface of the power supply, and then you can easily open the upper cover of the power supply, as shown in the figure below.
First remove the fixing screws.
It should be noted that at present, most power supply fans are designed to blow up or side. If it blows, the fan is fixed on the upper cover of the power supply. When disassembling, it must be noted that there is also a power cord inside the fan connected to the internal PCB. When disassembling, you need to open the cover carefully, and you need to disconnect the power cord before opening the upper cover, as shown in the following figure.
Note that the fan power interface should be disconnected.
Note: One of the four screws of the power supply has a fragile label with a date on the surface. Removing the power supply means that the warranty service of the power supply will be lost. Therefore, before removing the power supply, please find out whether the power supply has passed the warranty period, and if so, should it be solved through after-sales maintenance? After removing the power supply cover, you can see the internal cooling fan. Usually there are dimensions on it. Generally, the fan of ATX switching power supply is 300px. In terms of interface, most of the current power fan interfaces are 2Pin or 3Pin.
Second, the power supply fan replacement tutorial
After buying the power fan, you can start replacing the radiator. The specific steps are as follows. 1. Pull out the power cord of the power fan from the slot of the PCB power motherboard, which requires a little force; 2. Remove the fixing screw of the power supply fan with a cross screwdriver, and then remove the damaged fan; 3. Fix the new power fan in the power supply, then install the fixing screws, and insert the power cord into the power socket of the PCB board inside the power supply, being careful not to insert it backwards.
Next, don't rush to put the power supply into the chassis, first test whether the power supply fan will rotate.
1, plug the power supply into alternating current; 2. Then use a small iron wire to short-circuit the green line corresponding interface in the power supply 24Pin interface with the black corresponding interface (equivalent to computer startup operation), and then the power supply fan rotates normally, which means that the replacement of the fan is successful. If the fan does not turn, disconnect the AC power supply first, and then check whether the power interface of the fan is plugged backwards. Generally, as long as the power supply is not cut off, the fan is not cut off, and the black line and green line ports are normally short-circuited, the power supply is equivalent to normal work and the fan will rotate normally.
Question 7: How to refuel the fan in the computer case? Remove the fan and find the oil filler (usually stuck by the trademark). Pay attention to a drop or two when refueling, not too much.
Question 8: How to refuel the computer cooling fan? When you remove the fan and stick it on the heat sink, there is a small cover under the label. Open the shaft where you can see the fan and refuel here!
CPU fan, usually on the top cover
Large fans, such as power fans, are usually below. However, some fans can't see the hole where they can refuel when the labels on the front and back are torn off. The card on the shaft of this fan is inside, so you can't see it when you open the label. However, you can still find a way to make a small hole in the center of the refueling side of the ordinary cooling fan and refuel through this hole. Be careful not to add too much when refueling, so as not to overflow and damage other components.
Question 9: How to refuel the laptop fan? Never listen to those barefoot doctors. A laptop is not a desktop, just clean the fan. If the effect is not obvious, it's almost time to change it. After refueling, the seal is not good, and the waste motherboard is dumbfounded.
