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: "With the release of the NH-D14, Noctua brought to us a goliath of a passive CPU Cooler. It has dominated at Noctua’s top end solutions for over 4 years. One would think that the gigantism would end there. This isn’t the case as the newer and even bigger NH-D15 goes that one step further." (Farhan, Khan, TechLobby.co.uk)
