Why the speed of DC cooling fan slows down?

The speed of the cooling fan is determined by voltage, fan blade angle, diameter, number of fan blades, bearings, etc. So what is the reason why the cooling fan slows down?

The speed of the cooling fan is mainly determined by the structure and components of the fan itself, the bearing friction and the wind resistance of the inclination angle of the fan blade. If the air pressure of the cooling fan is not enough, the speed of the fan will also be affected.

1. The reason for the slow speed of DC cooling fan: first, check whether it has been used for too long. If it is not disassembled to clean the dust, there will be too much dust accumulation, which will make it difficult for the fan to rotate and slow down. It is recommended to clean regularly. Dust is very harmful to DC cooling fan.

2. The reason for the slow speed of DC cooling fan may also be the problem of power supply, so users can also consider replacing silent power supply or DC cooling fan. At present, there are many silent power supplies in the market, which can effectively reduce the power supply noise after strict testing. In addition, the DC cooling fan can be replaced better. The process of replacing the power fan is also very simple. The key is to pay attention to the connection between the fan and the power supply.

3. In addition, if the DC cooling fan is not installed and loosened during installation, the fan speed will also slow down. Therefore, it is recommended to be careful during installation and removal.
