Noctua NF-A6x 25 FLX 60mm Low Noise Fan Noctua's first 60mm fan features Smooth Commutation Drive technology, modular cabling, Low-Noise Adaptors & a massive six years manufacturer's warranty. Featuring advanced aerodynamic design measures such as Flow Acceleration Channels & Noctua's AAO frame, the NF-A6x 25 FLX is a highly optimised, premium quality quiet fan in 60x 25mm size. Smooth Commutation Drive technology & Noctua's reference class SSO2 bearings guarantee superb running smoothness & excellent long-term stability. Topped off with modular cabling, Low-Noise Adaptors & six years manufacturer's warranty, the NF-A6x 25 is a premium choice for the highest demands. Features 60 x 25mm quiet PC cooling fan Noise level from 8.2 d B (A) Feature packed Six year manufacturer warranty Flow Acceleration Channels The NF-A6x 25 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 & thus leads to better efficiency & lower vortex noise. More info. Reduced Motor Hub Size Thanks to its streamlined, compact motor design, the NF-A6x 25's motor hub is smaller than with conventional 6cm fans. This allows for more blade surface area & thus contributes to the NF-A6x 25's superior airflow & pressure performance. AAO Frame Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design & Inner Surface Microstructures, both of which further refine the fan's performance/noise efficiency. More info. 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 & increases suction capacity, especially in space restricted environments. More info. 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 & enhanced airflow & pressure efficiency. More info. Integrated Anti-Vibration Pads Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems & fan clips used on heatsinks. Smooth Commutation Drive 2 The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations & switching noises. This makes the NF-A6x 25 remarkably quiet even at very close distance. More info. SSO2 Bearing The NF-A6x 25 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 & durability. More info. Three speed settings for full flexibility Providing 3000, 2400 & 1600 RPM speed settings via the supplied Low-Noise & Ultra-Low-Noise Adapters, the NF-A6x 25 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness. 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 & the supplied 3:4 pin adaptor allows to connect the fan directly to the power supply. Six years manufacturer's warranty Noctua fans are renowned for their impeccable quality & outstanding longevity. Like all Noctua fans, the NF-A6x 25 features an MTBF of more than 150.000 hours rating & comes with a full six years manufacturer's warranty. Specifications: Size
