Fan module Noctua NV-AA1-12 12 cm Black
The Noctua NV-AA1-12 is an airflow amplifier designed for use with Noctua NF-A12x25 120 mm fans. It employs a three-way amplification system—helix energy recovery, progressive flow acceleration, and Venturi-effect volume enhancement—to convert the fan’s rotational and axial output into a strong, focused beam of air while preserving very low noise levels. The NV-AA1-12 is suitable for boosting performance in desk and room ventilation settings and allows similar ventilation performance at lower fan speeds compared with using the fan alone.
The NV-AA1-12 increases directed airflow without raising audible noise by recovering rotational energy from the fan, accelerating the flow through a tapered funnel and using the Venturi effect to draw in additional air. Its shape is optimised for the NF-A12x25 series, enabling efficient energy recovery and high outlet velocity. Installation is straightforward and it pairs well with mounting accessories for flexible placement.
Remove the fan’s pre-installed anti-vibration pads from the outlet side and fit the NA-AVG1 anti-vibration gasket between the fan and the NV-AA1 to avoid gaps. Align the NV-AA1 with the fan’s mounting holes and secure it using the supplied screws. Connect and operate the NF-A12x25 fan normally; the NV-AA1 will shape and amplify the output airflow when the fan runs.
For quiet desk or room ventilation, use the NV-AA1-12 with Noctua NF-A12x25 fans running at lower RPMs to achieve effective airflow with reduced noise. For flexible positioning, pair the assembly with the NV-FM1 pivoting mount; use USB-powered 5V PWM models for portable setups and the NV-PS1 supply for 12V models.
