Delivering up to 78.9 m³/h airflow at a whisper-quiet 22.8 dB(A), it offers fully automatic PWM speed control from 400 to 2000 RPM. Its AAO frame with anti-vibration pads and Flow Acceleration Channels ensures efficient, silent cooling, making it an elite choice for professionals demanding top-tier performance and durability. ## Description From the manufacturer The NF-A9 is a highly optimised, premium quality quiet 92mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9 further improves the renowned quiet cooling performance of the award-winning NF-B9. The PWM version sports 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 2000 to 1550rpm. Its superb running smoothness, reference-class 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. 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. SSO2 bearing The NF-A9 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. 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 other mounting systems. Scope of delivery NA-RC7 Low-Noise Adaptor (L.N.A) NA-YC1 4-pin PWM y-cable NA-EC1 30cm extension cable 4x NA-AV1 anti-vibration mounts Fan screws Inner Surface Microstructures With 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. Review: Excellent fan money can buy - Super airflow, great quality build, you see here in the photo, I used as a mod over my RTX A4000 GPU, with a 3D Printed air deflector to send air over PCB rear Review: Brilliant performance... - Very easy to install... used it with my nh-u9s air cooler. Cools my core i7 9700f with max upto 65°C. Pretty good performance for the price. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Noctua | | Compatible Devices | Desktop | | Cooling Method | Fan | | Noise Level | 22.8 Decibels | | Power Connector Type | 4-Pin | | Voltage | 12 Volts | ## Product Details - **Brand:** Noctua - **Compatible Devices:** Desktop - **Cooling Method:** Fan - **Power Connector Type:** 4-Pin - **Voltage:** 12 Volts ## Images ![Noctua NF-A9 PWM, 4-Pin Premium Cooling Fan for Desktop (92mm, Brown) - Image 1](https://m.media-amazon.com/images/I/81YGnt3WkSL.jpg) ![Noctua NF-A9 PWM, 4-Pin Premium Cooling Fan for Desktop (92mm, Brown) - Image 2](https://m.media-amazon.com/images/I/81Ls73P9HiL.jpg) ![Noctua NF-A9 PWM, 4-Pin Premium Cooling Fan for Desktop (92mm, Brown) - Image 3](https://m.media-amazon.com/images/I/91qyJZxtNML.jpg) ![Noctua NF-A9 PWM, 4-Pin Premium Cooling Fan for Desktop (92mm, Brown) - Image 4](https://m.media-amazon.com/images/I/91PsBrdmZOL.jpg) ![Noctua NF-A9 PWM, 4-Pin Premium Cooling Fan for Desktop (92mm, Brown) - Image 5](https://m.media-amazon.com/images/I/81G7boxoyKL.jpg) ## Questions & Answers **Q: Is this a 3 pin or 4 pin fan?** A: It is a 4 pin fan, however; it could be connected to 3 pin but it will run at full speed, according to the manual **Q: Does this fan come with a retension clip to attach to a nh-u9s?** A: No it does not but the nh-u9s comes with two sets of retention clips, two for each fan. **Q: Is this NF-A9 PWM delivered with a Y-adapter for two fan hookup?** A: Yes It is complete with a Y csble, an extension cable and a speed reducer.
