Noctua DIY Hairdryer?
Hi folks. Marginally related, I know.
Long story short, I have concerns with most hairdryers. Hot air & noise do not mix well sensory-wise with my autism.
Want to build a Noctua-powered hairdryer.
Obviously one could build a leaf-blower approach, but then noise considerations.
Which should I prioritize for better end product, static pressure or noise-normalized CFM?
I have tried using the desk fan nozzle (3D printed my own, a12x25 inside with the metal mount), and it works well but I want to scale this up.
Possibly iPPC fans? 200mm fans? Multi-fan inputs to a single output? How would that work in terms of internal turbulence? What would be a good software to computationally model with known fan parameters at different orientations / "nozzle" geometries?
Is a 3-fan 120deg offset (top of a trapezoid, effectively, with the desk fan nozzles pointing inward) the best bet using Noctua's math?
Diminishing returns probably exist at some point.
Would be interested this community's thoughts on the matter. If this is better suited to an r/askengineers or something, let me know. Just figured the brown owl would be my pick.
