When such a problem occurs, if the lubricant is not added in time, the fan may be damaged and the bearing clearance may be caused. The more it is worn, the louder and louder the noise will be, until the fan is scrapped; in worse cases, the CPU heat dissipation is poor, causing frequent crashes or restarts for no reason, and in more serious cases, the CPU may be burned. Some friends don’t understand and think that the fan is broken. They go to the computer market and spend dozens of dollars or more to buy a new one. In fact, they just need to add some oil. The process is not complicated, and the effect is significant. You can also experience For DIY fun, the steps are as follows: Tool preparation: 1. A screwdriver (maybe two, because the fixing screws of the chassis and the fixing screws of the CPU fan may be different); 2. Lubricating oil (also known as " "Motor oil") a few drops (actually it can't be so little, because you can't get it if it is so little), it doesn't matter if the viscosity is slightly higher, anything between No. 32 and No. 100 will do. If not, you can use ordinary sewing machine oil, butter (not the kind sandwiched in bread, the kind scientifically called "calcium-based grease", don't be ridiculous), or molybdenum disulfide. I've used all of these and it's fine. Note: Do not use edible oil. This oil will become sticky the more you use it, which will affect the normal operation of the fan. After all, it is used for eating and not for lubrication. You should not use water to "lubricate" it. I have seen people using water. I came to clean and "lubricate", and I almost fainted. The man was an electrical major, let's not talk about him. 3. A toothpick (for refueling), of course you can use wire or something similar, as long as it can be dipped in two drops of oil; 4. A brush (if not, you can use an old toothbrush instead to clean the fan and dust on the heat sink); when the fan is disassembled, you can see that the fan blades and heat sink are covered with dust. At this time, you should find a brush to clean away the dust on the heat sink and fan blades, and peel off the plastic film on the bottom of the fan. Note: Do not uncover it all, just expose the bearing (** part). It will not be easy to stick it on after it is completely uncovered. At this time, you can see that the bearing is dry and there is no lubricating oil. The cause of the noise is to dip a little lubricating oil here and carefully drip it on the fan bearing. Note: Just three to five drops is enough, not too much, otherwise it will overflow outside and become sticky, which will attract dust. In addition, if the lubricating oil spills out, it will make it difficult for the plastic film to be reattached. In addition, each drop of oil will rotate the fan blade several times to allow the added lubricating oil to infiltrate into the bearing. After adding oil, reattach the plastic film. At this time, you should blow a few blows on the fan blade to see if it can rotate flexibly. If it does not rotate, it means there is still something stuck inside, and it needs to be lubricated again until it rotates fully and flexibly. If you find it is a machineIf the fan of the box power supply is noisy, you can also use this method. Note: The source of oil is the bicycle repairman who has butter. If you ask him for a piece as big as a quail egg and give him 50 cents (it’s too little to hand over), he will be absolutely beautiful, so much. Oil isn't worth a dime, but if you buy it in a store, they won't retail it. If you go to a shop that repairs motorcycles or cars, you must have oil. If you ask for their used oil, you can get a small bottle and get some. It should be free of charge. Other causes of chassis noise: 1. There are 2 to 6 fans in the fan chassis, including power supply fans, chassis fans (some do not), CPU fans, graphics card fans (some do not), and north and south bridge chip fans (some do not). First of all, you need to confirm where the noise comes from (this shouldn't be difficult). Maybe the noise comes from other fans; in addition, the fixation must be firm, otherwise it will resonate with the motherboard chassis and there will be noise. 2. Hard drives. Today’s hard drives are generally less noisy. Older hard drives can hear a “squeaky” sound when they rotate. This is the sound of its spindle motor. There is no way to solve it. It is a normal phenomenon. Others can hear a “squeaky” sound. The sound of "clucking" is the sound of the hard disk reading (writing) the disk. It is usually felt by everyone. After defragmenting the disk, the sound will be smaller, but the effect is not significant; if the sound of the hard disk reading (writing) the disk is very loud If it is large, then you should pay attention. It may be a precursor to bad sectors in the hard disk. If you find that the hard disk read and write speed is slowing down at this time, you must be more vigilant and take necessary measures to prevent data loss. 3. It’s hard to tell about electronic components. They generally produce high-frequency sounds, and some sound different depending on the program being run. There is no other way than replacing the components. I guess it's the oscillator inside. Why is the noise still louder after adding oil? It may be that there is dirt in your bearing, and there is a lot of it. Even if you add oil, it is still not lubricated effectively and the noise is still loud. If you want to solve the problem, you must first remove the dirt! You can clean it with kerosene first (of course, flushing with a large amount of lubricating oil will also work, but the effect is not good). The flushing position is the center of the bearing. While flushing, blow the blades with your mouth until the fan rotates rapidly, and then clean the outside. Wipe it clean with kerosene, drop lubricating oil into the bearing, and seal it with a protective film. (Do not use strong soluble solvents such as gasoline, alcohol, ether or acetone for flushing. This may dissolve the plastic shell. In particular, it may also dissolve the enameled wire of the internal rotor, which will cause the fan to be scrapped.) Note: I The "flushing" mentioned here does not mean that you use high-pressure liquid to flush it like a car wash. It is just a word used. The operation is nothing more than adding lubricating oil, adding and turning until it rotates flexibly.
