By virtue of its own diversion function, the cooling fan has the characteristics of fast speed and good heat dissipation effect, but many people will encounter a problem, that is, the purchased cooling fan sometimes does not rotate after being used for a long time, or sometimes slows down. Suddenly, and there are many reasons for this failure, what should I do if the cooling fan does not rotate? Don't panic the cooling fan manufacturers to share the solution of the cooling fan does not turn.

       What should I do if the cooling fan does not turn? The reasons and solutions are as follows:

　　 1. The cooling fan works under high temperature for a long time:

Reason: There are many reasons for the cooling fan not to rotate. The fan is broken, and the power supply problem is also one. But in general, the fan is not broken, because the cooling fan works at high temperature for a long time, which will easily cause the fan. The lubricating oil dries up.

Solution: You can try to rotate it with external force by hand. If there are signs of fretting or the rotation resistance is very large, it means that the fan is not problematic, but the lubricating oil is dry. You can remove the fan. Generally, there is a sticker on the reverse side. The adhesive sticker can be removed. At this time, you can see the fan shaft, add some oil or something, turn it a few times with your hands, and feel that there is no resistance. Putting it back on should solve the problem.

　　2, the cooling fan rotates slowly, or even does not rotate:

Reason: As a machine, failure is inevitable. We do not choose to replace it immediately. We must find the cause from the faulty cooling fan. If the fan of the radiator stops rotating, one of the possible reasons is heat dissipation. The speed of the fan does not reach the normal speed required for the radiator to work. In this way, if the cooling fan cannot reach its operating power, the result of such a slow rotation or even no rotation will occur, and the heat dissipation effect will definitely not be as good as before.

　　 Solution: We can try to adjust the fan blades so that its speed can meet the corresponding power requirements of the radiator. This time not only solves the problem, but also saves you the trouble of replacing a new device.

　　 3. Not paying attention to cleaning and maintenance:

Reason: Because the environment where the cooling fan is located is relatively dusty, or it has been used for a long time, and we have not cleaned it, it is likely that the power supply of the cooling fan cannot rotate due to excessive dust. This is mainly due to The accumulation of heat inside the cooling fan increases, resulting in poor heat dissipation inside the power supply, and unstable power supply, resulting in instability.

　　 Solution: Pay attention to the maintenance of the cooling fan and clean it regularly.

　　The solution to the cooling fan not turning is shared here. From the above content, we can know that there are many reasons for the cooling fan not turning, so we need to analyze the core reasons to find a suitable solution!
