Laminar Flow Fan plate

The airflow turbulence has been significantly reduced, resulting in a much more controlled flow and increased pressure. Curved blades produce less noise but at the cost of compromised performance due to early stalling (turbulent air flow) under lower static pressures compared to straight blades. The same design concept is visible in Noctua NF-F12 fans and SilverStone Air Penetrator fans. To see this principle in action, check out a video from SilverStone. I've successfully printed the 92mm and 120mm versions, which are functioning properly. This design applies specifically to curved edge fans rotating counter-clockwise (approximately 99.9% of all fans). Although I haven't measured the change in the P-Q curve, it's likely that it creates an entirely new curve. The slicing process was done using Cura within Repetier Host V1.0.2 without any issues. For optimal results, attach the plate to the exhaust outlet with the letter Q facing outward. 20-August: A 40mm V4 plate has been added, which is slightly more challenging to print due to its thinner blades. However, it performs similarly to the others. I tested this on a Fan FD244010HB and observed a loss of flow ranging from 2-4% along with a gain in pressure between 15-20%.
