Premium 92mm PWM fan for compact builds
The NF-A9 PWM is a 92mm case fan designed for CPU coolers, water-cooling radiators and small-form-factor cases where space is limited. Its 4-pin PWM connector enables automatic speed control from 400 to 2000 RPM through standard motherboard headers. The brown colour scheme matches Noctua's signature aesthetic without any LED lighting.
Sustained airflow with acoustic optimisation
Flow Acceleration Channels on the impeller reduce flow separation at the outer blade regions, maintaining efficiency during continuous operation. The Advanced Acoustic Optimisation frame integrates anti-vibration pads, Stepped Inlet Design and Inner Surface Microstructures to lower vortex noise. At full 2000 RPM the fan delivers 46.44 CFM at 22.8 dB(A); with the supplied Low-Noise Adaptor it runs at 1550 RPM for 36.84 CFM at 16.3 dB(A).
SSO2 bearing and versatile mounting kit
The self-stabilising oil-pressure bearing is rated for more than 150000 hours MTTF, supporting long-term reliability under constant load. In the box you receive four vibration-compensating mounts, four fan screws, a 30cm extension cable and a 4-pin Y-cable for running two PWM fans from one header. The 92x92x25mm frame fits standard 92mm mounting patterns without modification.

| Features | Succeeding the award-winning NF-B9 Noctua's NF-B9 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 92mm fan. Thanks to its thoroughgoing aerodynamic optimisations, the NF-A9 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor. Flow Acceleration Channels The NF-A9 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. |

Spørgsmål om denne vare
How loud is the NF-A9 PWM at its standard 2000 RPM speed?
At 2000 RPM the fan produces 22.8 dB(A). With the supplied Low-Noise Adaptor limiting speed to 1550 RPM, noise drops to 16.3 dB(A).
Does the NF-A9 PWM need a 4-pin PWM header on the motherboard to run?
Yes, the 4-pin PWM connector plugs into a standard 4-pin fan header for automatic speed control between 400 and 2000 RPM.
Will the NF-A9 PWM fit the screw pattern of my older 92mm case or cooler?
The fan uses the standard 92mm mounting holes (92.00 x 92.00 mm) and includes vibration-compensating mounts plus regular screws for backward-compatible installation.
