Certainly but as I’ve learned the economics aren’t there. In a previous role we developed a novel heatsink and fan design and saw some licensing interest. We learned that all that matters for thermal management solutions was cost above all else. Existing designs were good enough.
Idk, Noctua's clearly making bank off premium ultra quiet fans. At least from me.
You're way not alone. Love those ugly-brown quiet-machines. Still, they're probably looking at this and think "Nah, our optimizations are way cheaper to manufacture and wholly sufficient" (because they are :)
Is the fan shroud not mostly solving or mitigating the tip vortex issue on something like a computer fan?
