Inner Surface Microstructures

Inner Surface Microstructures are an advanced aerodynamic design measure first introduced with Noctua’s NF-F12 fan. Miniature dents at the inside of the fan frame create a turbulent boundary layer when the fan blades pass by. With the tips of the fan blades ploughing through this boundary layer, flow separation from the suction side of the blades is significantly reduced. As suction side flow separation is a major source of axial fan blade passing noise and leads to considerable losses in airflow and pressure efficiency, the use of Inner Surface Microstructures allows for lower noise emission and better performance at the same time. Reducing undesired turbulences caused by suction side flow separation, Inner Surface Microstructures help Noctua’s latest fans to keep pushing the boundaries in performance to noise efficiency.

Test verdict: "Noctua nous fait part de deux gamme bien distinctes et qui ont deux publics différents. En effet, la gamme Redux se veut plus grand public avec des vitesses de fonctionnement plus bas et des bruits également plus bas. De son côté, la gamme iPPC se veut plus orientée industrie grâce à la présence de la norme IP 52. Les deux gammes proposent des performances de ce nom tout en étant performantes a des prix plutôt attractifs. La gestion PWM est également un plus pour ceux voulant un bruit faible provenant de sa tour." (Batiste Hocq, Syndrome-OC.net)

Test verdict: "Noctua has raised the bar once more for high end air cooling products: the NH-D15 is without a doubt a stellar performer, in combination with the two included brilliant 140mm PWM fans it still keeps noise level reduced to a minimum. Even when running the D15 with a single centered fan the cooling performance is more than adequate to cool down your overclocked processors. Noctua has provided every accessory you need with this NH-D15, from the big thermal paste syringe to the Low Noise Adapters, everything you will need is included." (Albrecht Mesotten, Madshrimps.be)
