Lets come to this, how to choose no of blades, please consider below matters before choosing the no of blades
1. When no of blades increases, it will reduce the noise while running
2. And also you need to consider this while u choose higher blade fans, because efficiency will gets reduced i.e, RPM (Rotation per minute) will get reduced due to the increase in the weight while choosing 4 r 5 blade fans

In this case, you need to compromise performance
