Yes, though the fidelity offered by faithful CAD would be both easier to interpret correctly and might even hint at the CAD feature tree.

Kudos to them for releasing models useful for integration.

From what I remember from my NASA friend, a few companies, hired a few fluid flow engineers, during the defense bust, and designed fan blades that remarkably increased air flow. ( think profiles like air plane wing ). Something happened and in a few years, there were good fans, and there were great fans.

I happen to own a pair of Noctura fans, and wow! They are great, so I would assume that some heavy lifting was done in fluid flow.

  • It better have been, considering what they charge and how long they take to come out with new ones.
