According to Fandiego, “With all things being equal, the ceiling fan with fewer blades will outperform (better airflow) the fan with more blades. It will actually move more air. Here's why: With fewer blades, more air is actually circulated through the blades. This makes the fan less efficient.
.
Just so, does the number of fan blades make a difference?
However, the laws of physics do dictate a slight difference in performance between ceiling fans with different numbers of blades. As a rule, as the number of blades goes up, the fan tends to be quieter and circulates less air. Additional blades increase the drag on a ceiling fan's motor and slow it down.
Beside above, do 3 blade fans work as well as 5 blades? There is a common misconception that five ceiling fan blades work better than four or even three blades. Homeowners assume that five blades means better air movement, circulation, and less cooling costs, but in reality, all five blades do is add aesthetic appeal.
In respect to this, how many blades on a ceiling fan make the best airflow?

Is a 3 blade fan better than a 4 blade fan?
So, it is ideal to find three blade ceiling fans for optimum airflow that works with lesser friction. In this case, the motor load is also manageable, and you are protected from unnecessary noises. While having four blades might improve the aeration, it can increase the amount of load on the motor.
