(Summary description)The reason why the cooling fan suddenly does not turn 1. Power failure: If the power supply of the fan fails, such as disconnecting the power cord or loosening the power plug, it can cause the current to not be transmitted normally, resulting in the fan stopping running. 2. Low temperature: Some heat dissipation windbreakers have temperature protection function. When the temperature is too low, the fan will automatically stop working to avoid excessive cooling. This usually occurs in low-temperature environments, such as winter or air-conditioned environments. 3. Lubricating oil drying up: It is possible that the lubricating oil has dried up. Try to rotate the fan with your hand. If there is any sign of slight movement or if you feel that the rotation resistance is very high, it indicates that the fan is not a problem. However, if the lubricating oil has dried up, remove the fan. Generally, there is a sticker on the opposite side, and when you remove it, you can see the fan shaft. Add some lubricating oil such as engine oil, Then rotate the fan a few more times by hand, feeling that there is no resistance or the resistance is very small, and reinstalling it can almost solve the problem. 4. The speed has not reached the normal speed required for operation 5. Fan controller failure: Some advanced cooling fans are equipped with controllers. If the controller fails, such as burning out the circuit board or damaging circuit components, it can cause the fan to stop running. 6. Overload protection: When the cooling fan is working, if the load is too large, such as in case of overclocking or overvoltage, the fan power current may exceed the rated value, which will trigger overload protection and the fan will stop rotating to protect the circuit. 7. Not paying attention to cleaning and maintenance: Due to the environment where the cooling fan is located being dusty or used for a long time, and we do not clean it very much, it is very likely that the power supply of the cooling fan cannot rotate due to excessive dust. This is mainly because as the dust increases, the internal heat accumulation of the cooling fan also increases, leading to poor internal heat dissipation of the power supply and unstable power supply, The fan speed is also unstable, so it is important to maintain the cooling fan and regularly clean it. There are many reasons why the cooling fan does not turn. It may be an external cause of the cooling fan, or it may be a malfunction or damage caused by the cooling fan during operation. If the cooling fan suddenly does not turn, it is recommended to check whether the power connection is normal, whether the power supply provides sufficient voltage and current, and whether the fan has overload protection functions. If these are all correct, it may be necessary to check whether the fan itself has mechanical or controller faults, and further maintenance or replacement is needed. Before carrying out any repairs or replacements, it is recommended to refer to the relevant fan manual or consult a professional.
