What If the Noctua NF-A12x25 Had Twice as Many Blades? | Custom 3D Printed Blades

I have always found fan design interesting, companies spend hours upon hours and millions of dollars trying to fine tune the design of their fans to move more are while also making less noise. Have you ever wondered why they choose the amount of blades they do. I have so I decided I would copy one of the best fans on the market and test out 2 other configurations, a 3 blade design and an 18 blade design. One would think more blades means more static pressure but is that all there is to it.
