Noctua NF-A6x15 FLX Slim 60x15mm premium fan

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame. the NF-A6x15 is a highly optimised. premium-quality quiet fan in size 60x15mm. The FLX version provides 3500/3050/2250rpm speed settings via the supplied Low-Noise Adaptors in order to give full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness. SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.Flow Acceleration ChannelsThe NF-A6x15 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.AAO frameNoctua'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.Stepped Inlet DesignNoctua'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.Inner Surface MicrostructuresWith 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.Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and most other mounting mechanisms.SSO2 bearingThe NF-A6x15 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.Smooth Commutation Drive 2The latest version of Noctua’s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-A6x15 remarkably quiet even at very close distances.Extensive cabling optionsThe 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.3 speed settings for full flexibilityProviding 3500. 3050 and 2250rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adaptors. the NF-A6x15 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.6-year manufacturer’s warrantyNoctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans. the NF-A6x15 features an MTTF rating of more than 150.000 hours and comes with a full 6-year manufacturer’s warranty.
