Award-winning 60x15mm A-series fan with Flow Acceleration Channels and Advanced Acoustic Optimisation frame for superior quiet cooling performance
Ideal replacement for noisy or broken 12V 6cm fans in DVRs, NAS, network and storage devices, 3D printers, etc.
4-pin PWM version for automatic speed control via 4-pin PWM fan headers, 3500rpm maximum speed (3050rpm with supplied Low-Noise Adaptor)
Includes anti-vibration mounts, fan screws, Low-Noise Adaptor, extension cable and y-cable for running two PWM fans on the same header

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 PWM version uses Noctua's custom-designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed during PWM control from 3500 to 3050rpm. Its superb running smoothness, 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

Integrated 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 bearing

The 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.

Flow Acceleration Channels

The 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.

Scope of Delivery

4x NA-AV2 anti-vibration mounts
NA-EC1 30cm extension cable
NA-YC1 4-pin PWM splitter cable
NA-RC14 Low-Noise Adaptor (L.N.A.)
Fan screws

Custom-designed PWM IC with SCD

Supporting fully automatic PWM speed control, the NF-A6x15 PWM uses Noctua's custom-designed NE-FD1 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.
