Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown)

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua's AAO frame, the NF-A6x25 FLX is a highly optimized, premium quality quiet fan in 60x25mm size. Smooth Commutation Drive technology and Noctua's reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, Low-Noise Adaptors and 6 years manufacturer's warranty, the NF-A6x25 is a premium choice for the highest demands.


Flow Acceleration Channels


The NF-A14 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.



Reduced Motor Hub Size


Thanks to its streamlined, compact motor design, the NF-A6x25's motor hub is smaller than with conventional 6cm fans this allows for more blade surface area and thus contributes to the NF-A6x25's superior airflow and pressure performance.



A4O Frame


Noctua's A4O (Advanced Acoustic Optimization) 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.



Stepped Inlet Design


Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar to flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity especially in space restricted environments.Fan Size
