While this is neat, it strikes me as the software developer's idea of a "smart fan". The engineer in me says that an actual "smart fan" would be one whose blades are designed to produce maximum airflow with minimum noise (variable pitch? avoiding turbulence?)

I think you're describing a "great" fan. A "smart" fan is one that thinks. e.g. smart TVs are worse (and therefore cheaper) than dumb TVs, but they do a lot more thinking.

They're describing an efficient fan. A great fan would be one that offers the best attributes such as efficiency, quality and features. Though, I agree the term "smart" should denote some kind of CPU enabled automation and features.

He’s using a noctua fan which are pretty much the quietest pc fans you can buy while still moving large amounts of air
