Smooth Commutation Drive technology and SSO-Bearing guarantee benchmark superb quietness and outstanding long-term stability. Modular cabling, Low-Noise Adapter and 6 years warranty make the NF-A6x25 a premium solution for high performance.

The impeller of the NF-A6x25 is equipped with so-called suction Flow Acceleration Channels. By the acceleration of the air flow in the critical regions of the fan blades outer suction vortex shedding can be reduced, which leads to a higher efficiency and a lower vortex induced noise emission. Thanks to an optimized and compact motor design of the hub of the NF-A6x25 is clearly smaller than in conventional fans 6cm. Thus, a larger blade surface can be realized, which contributes to the superior pressure and flow rate of the NF-A6x25.

Noctua AAO (Advanced Acoustic Optimisation) framework have built vibration buffer and a stepped inlet area (Stepped Inlet Design) and a microstructure inside (Inner Surface Microstructures), enabling an even better performance / noise efficiency. By the stepped inlet area of the Stepped Inlet designs in supply caused more turmoil. Thus, the transition from laminar to turbulent flow is facilitated adhered better to the frame (Flow Attachment) and thus increase especially with limited absorptive capacity of the intake fan.

The micro-structure in the inner region of the frame (Inner Surface Microstructures) creates a boundary layer, by moving the tips of the fan blades. This separation reduces the power of the suction side of the blade tips, which is a considerable reduction in the pressure and an increase Drehtons airflow and efficiency with the result. Made of extra-soft silicon anti-vibration pads reduce transmission minimal vibration and are at the same time with all standard screws and standard mounting systems or CPU coolers used fan brackets compatible.

The latest, enhanced version of Noctua's advanced SCD drive system ensures by eliminating torque variations and switching noises outstanding quietness. This makes the NF-A6x25 even at close surprisingly quiet. The NF-A6x25 has the further optimized second generation of Noctua-grade SSO-bearing system. SSO2 in the rear magnet is closer to the fan axis, causing an even better stability, which leads to a further improvement in precision and durability.

The NF-A6x25 FLX (Flexibility) provides via the supplied Low-Noise and Ultra-Low-Noise Adaptor 3,000, 2,400 and 1,600 rev / min settings and allows fine tuning for superior airflow or maximum quietness. While the 20 cm short primary cable helps in typical applications, to avoid clutter, the supplied 30cm extension provides extra coverage for all cases. Both cables are completely encased.

Noctua fans are known for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-A6x25 an MTBF specification of over 150,000 hours and comes with full 6 years manufacturer's warranty.
