Specifications Size 60x60x25 mm Connector 4pin PWM Bearing SSO2 Blade Geometry ASeries with Flow Acceleration Channels Frame Technology AAO Advanced Acoustic Optimisation Rotational Speed +/ 10% 3000 RPM Rotational Speed with L.N.A. +/ 10% 2300 RPM Min. Rotational Speed PWM +/20% 550 RPM Airflow 292 m/h Airflow with L.N.A. 226 m/h Acoustical Noise 193 dBA Acoustical Noise with L.N.A. 137 dBA Static Pressure 218 mm H2O Static Pressure with L.N.A. 129 mm H2O Max. Input Power 096 W Max. Input Current 008 A Voltage 12 V MTBF > 150.000 h Flow Acceleration Channels The NFA6x25 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. button Reduced Motor Hub Size Thanks to its streamlined compact motor design the NFA6x25's motor hub is smaller than with conventional 6cm fans. This allows for more blade surface area and thus contributes to the NFA6x25's superior airflow and pressure performance. AAO Frame Noctua's AAO Advanced Acoustic Optimisation frames feature integrated antivibration 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. button Stepped Inlet Design Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow which reduces tonal intake noise improves flow attachment and increases suction capacity especially in space restricted environments. button 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. button Integrated AntiVibration Pads Integrated AntiVibration Pads made from extrasoft 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 NFA6x25 features the further optimised second generation of Noctua's renowned timetested SSO bearing. With SSO2 the rear magnet is placed closer to the axis to provide even better stabilisation precision and durability. button Custom designed PWM IC with SCD Supporting fully automatic PWM speed control the NFA6x25 PWM uses Noctua's custom designed NEFD1 PWM IC that integrates Smooth Commutation Drive SCD technology. By providing smoother torque impulses SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds. button LowNoise Adaptor The NFA6x25 PWM is supplied with a LowNoise Adaptor L.N.A. that reduces the maximum fan speed from 3000 to 2300rpm. The L.N.A can be used either to run the fan at a fixed speed of 2300rpm or to cap the maximum speed when using automatic PWM control. Extensive cabling options The fan's short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4pin ycable allows to connect a second NFA6x25 PWM fan to the same PWM fan header for automatic control.
