I recently bought several different models of electric fans to use to keep cool. Some are square box fans, others are circular, but all are “traditional” fans with blades that spin behind a plastic grate. The minimum setting on every one of them is too powerful and pushes too much air out (at least for me). Is there a reason (electricity, fluid dynamics, etc.) they can’t have a lower setting?

Most people want a fan that can function with a good degree of power, so it takes a certain size motor to do that. If you progressively turn that motor lower and lower it will eventually stall as there’s not enough power to overcome the internal friction and push air. If you sold a fan with a weak motor, it would not be able to handle high power that most people want and it would burn out.
how about putting the fan farther away, or not having it pointed directly at you?
