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: "The NH-C14S definitely took the cake for C-types. The cooling capabilities are great and the residual airflow cools your motherboard components as well. If you are in the market for a C-type cooler look no further as the NH-C14S will meet your demands." (Chris McCart, FunkyKit.com)
