How to disassemble the 15050 aluminum frame AC fan

We may all encounter computer component failure. It is not easy to move important parts without certain knowledge, but if there is a problem with the cooling fan, it is not difficult to remove them even by ordinary people. Next, let's learn how to remove the 15050 aluminum frame AC fan, so that the removal of the cooling fan requires no one.
The CPU cooling fan is a little noisy after a long time. Don't be willing to replace it and handle it yourself. Everything starts with saving.
How to remove the desktop computer fan and how to refuel the CPU fan
1. The first step is to remove the fan. Hold the bottom of the fan with both hands, and press the middle part of the fan outward with two thumbs of both hands. Be careful not to push the fan leaf. The closer it is, the better it is. Avoid breaking the fan. Don't be afraid to break it with a little force. It will come out smoothly after reaching the power point. (If you are not sure, you can find an old fan, try it out, and then dismantle the fan.)
2. Start removing the fan:
3. Be careful not to push the fan leaves. The closer the fan leaves are, the better. Avoid folding the fan
4. It's really dirty. The stain is covered with the shaft sleeve. It needs to be cleaned:
Dismantle and clean the shaft sleeve, which is the culprit of the loud noise of the CPU fan. When removing the shaft sleeve, gently remove the plastic stopper at the top of the shaft with a small slotted screwdriver, and then the shaft sleeve can be removed from the shaft smoothly.
At this point, we must pay attention to the installation direction of the shaft sleeve. It is best to take photos before dismantling, because one end of the shaft sleeve is chamfered, and if it is installed reversely, it will seriously affect the rotation of the fan; And don't lose that plastic stopper.
5. There is a lot of dust.
6. These parts must be put away properly. If they are lost, they will be scrapped.
7. Clean the coil assembly and shaft sleeve clamp groove. They do not participate in friction rotation, but if not cleaned, these dust will fall onto the shaft, indirectly affecting the rotation of the fan:
8. The cleaned fan is much cleaner. Although there is some dust in the dead corner, there is no way to clean it. It is too difficult to clean it. Besides, it really does not affect anything, so let it go.
9. Drop a few drops of lubricating oil and mechanical lubricating oil in the shaft sleeve clamp slot. If there is no lubricating oil, it will be better to use butter
10. Fan after cleaning:
11. The sound of the CPU fan is much quieter after it is removed, refueled and cleaned, but it is impossible to be as quiet as it just left the factory, but it can still be used for a while.
How to remove the cooling fan? To sum up, the removal of 15050 aluminum frame AC fan is actually relatively simple. But this does not mean that we can be careless when removing the cooling fan. In the process of disassembly, we need to ensure that other parts inside the computer will not be damaged with our disassembly action, which is very important.
