Reasons for slow speed of DC cooling fan

Release time:

2022-03-08

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 for the slow cooling fan?
The main determining conditions for the speed of the cooling fan are the structure and components of the fan itself, the bearing friction and the wind resistance of the fan blade angle. If the wind pressure of the cooling fan is not enough, it will also affect the speed of the fan.
1. The reason for the slow speed of the DC cooling fan First check whether it has been used for too long and has not been disassembled to clean the dust, resulting in excessive dust accumulation, causing the fan to be difficult to rotate and the speed will slow down. It is recommended to clean up regularly. Dust is very harmful to the DC cooling fan.
2. The reason for the slow speed of the DC cooling fan may also have problems with the power supply, so users can also consider replacing the silent power supply or the DC cooling fan. At present, there are many silent power supplies on the market, which can effectively reduce power supply noise after strict testing. In addition, the DC cooling fan can be better replaced. The process of replacing the power supply 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 loose during the installation process, the fan speed will also slow down. It is recommended to be careful when installing and removing.
