What is the reason for the slow speed of the cooling fan

The speed of a cooling fan is generally determined by its voltage, blades, and number of blades. The reason for its slower speed is caused by the following factors. Let's follow the manufacturer to learn more!
1. The general cause of the impact may be external environment, high or low temperatures, or sandstorms.
If the wind speed slows down, we can also check to see if there is a lot of dust on the components and blades of the cooling fan. The accumulation of dust can also affect its speed.
3. We also need to check if the installed fan is installed correctly. If the fan is not installed properly, it may slow down the speed if it becomes loose after prolonged use.
