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.

Advantages

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.

Suitable for

• Desk fans and personal cooling where a focused air beam is required
• Room ventilation applications with medium-range airflow requirements
• Situations requiring lower fan RPMs to reduce noise while maintaining airflow
• Integration with pivoting mounts or custom mounting solutions

Key specifications

• Compatible fan size: 120 mm (Noctua NF-A12x25 series)
• Amplification system: Helix energy recovery, progressive flow acceleration, Venturi-effect volume enhancement
• Colour: Black
• Mounting: Screws to fan mounting holes (screws supplied)
• Optimised for: NF-A12x25; compatible with 5V PWM USB-powered models and 12V models (use NV-PS1 for 12V)

How to use

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.

Recommendations

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.
