The main difference between a 4- and 5-blade ceiling fan is one of aesthetics and personal taste. Additional blades increase the drag on a ceiling fan's motor and slow it down. This is one of the reasons why industrial fans (like wind turbines) usually have only two or three blades.
.
Likewise, people ask, is a 3 or 4 blade fan better?
There is not a great deal of difference between the performance features of a 3,4 or 5 bladed fan – so it's about the fan design you prefer. Though with 5 blade fans these will usually require a larger motor to rotate the blades and larger motors generally means higher energy consumption.
Subsequently, question is, do more blades make a fan better? In other words, air is more effectively circulated with fewer blades, because as the number of blades increases, more air has to be pushed around the blades. This makes the fan less efficient. Having fewer fan blades also decreases the weight on the ceiling fan motor so the motor can spin faster, circulating more air.”
