Noctua NF-A4x10 PWM, Premium Quiet Fan, 4-Pin (40x10mm, Brown)

Brand: Noctua

Noctua NF-A4x10 PWM Premium Quiet Fan 4-Pin (40x10mm Brown)
Product Description

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame the NF-A4x10 is an award-winning premium-quality quiet fan in size 40x10mm. The PWM version sports Noctua’s custom-designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise Adaptor as well as an OmniJoin Adaptor Set for easy connection to proprietary fan headers. Its superb running smoothness reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.

^{AAO frame}

Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures both of which further refine the fan's performance/noise efficiency.

Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.

^{SSO2 Bearing}

The NF-A4x10 features the further optimised second generation of Noctua's renowned time-tested SSO bearing. With SSO2 the rear magnet is placed closer to the axis to provide even better stabilisation precision and durability.

^{Reduced motor hub size}

This allows for more blade surface area and thus contributes to the NF-A4x10's superior airflow and pressure performance.

^{Inner Surface Microstructures}

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures flow separation from the suction side of the blades is significantly suppressed which results in reduced blade passing noise and improved airflow and pressure efficiency.

By speeding up the airflow at the crucial outer blade regions this reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
