I guess electric fans have their place, but one of the main reasons people use them is to reduce noise. However, it's difficult, if not impossible, to move a large quantity of air without noise. That's why you hear garbage trucks, semi's, buses etc with extremely loud engine fans...they do the job.

Roger that. I have to occasionally select cooling fans for electronics enclosures, and if it is going in a quiet location, one simply has to go to a very low fan speed, and use a larger enclosure, and use internal stirring fans. And we use boxer type fans with stout blades and a thick fan body to keep the blades efficient, not these thin bladed things from the auto catalogs.
