The speed of the cooling fan is generally determined by its voltage, blades and the number of blades. The reason for its slow speed is caused by the following points. Let's follow the manufacturer to understand!
1. The general impact may be caused by external environment, high or low temperature, or sandstorm.
2. If the wind speed slows down, we can also check to see if there is a lot of dust on the parts and blades of the cooling fan. The accumulation of dust will also affect its speed.
3. We also need to check whether the installed fan is installed correctly. If the fan is not installed correctly, the fan becomes loose after a long time of use will also lead to slower speed.
