You’re basically trading energy to move higher volume of air. The fan can move smaller amount of air at higher speed, but larger amount at a gentle breeze feels nicer and helps with circulating the air in the room better. You could achieve it by taking that exact motor and slapping a bigger fan onto it, but that looks less cool and probably produces more noise? Maybe there’s some efficiency differences if the motor is better at spinning fast, but as a spherical cow in vacuum it should be similar.
