Featuring advanced acoustic optimization, PWM speed control from 400 to 2000 RPM, and a legendary >150,000-hour lifespan, it delivers whisper-quiet airflow with rock-solid reliability. The package includes anti-vibration mounts, extension cables, and a Low-Noise Adaptor, making it the ultimate choice for professionals seeking silent, efficient cooling without compromise. ## Description Product description 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: Good little fan and worth the extra price. Quiet and lasts forever - Bought this to replace the broken stock fan in my UGREEN NAS DXP2800 and it ended up being a perfect drop‑in upgrade. Noise level: At typical NAS fan curves it’s basically whisper quiet, even sitting on a desk a few feet away. Cooling: Despite the low noise, it moves enough air that my drive and system temps stayed the same or slightly improved compared to the original fan. Cable length: The included cable is long enough to route cleanly inside the NAS without needing an extension or weird bends. Mountability: Standard 92mm mounting holes lined right up; swap took a few minutes with just a screwdriver and no mods needed. Speed and airflow: PWM control works as expected, ramps smoothly under load, and at higher RPMs you get noticeably stronger airflow without a huge jump in noise. Overall, if you’re looking for a reliable, quiet replacement fan for a small NAS or SFF build, this one is worth paying a bit extra for. Review: Best 92mm fan on the market - The Noctua NF-A9 PWM (92mm, 4-pin) is one of those components that quietly justifies its premium price — literally and figuratively.I've used several Noctua fans over the years, and this 92mm PWM model continues the brand's reputation for exceptional build quality and acoustic performance. At max 2000 RPM it pushes a solid amount of air (around 78.9 m³/h), yet the noise tops out at just 22.8 dB(A) — in practice, it's barely audible even in a near-silent room unless you put your ear right next to the case. With the included Low-Noise Adaptor plugged in, it becomes whisper-quiet while still providing perfectly adequate cooling for most 92mm applications.What stands out:The PWM control is smooth and responsive; the fan ramps up/down almost imperceptibly as temps change. Flow Acceleration Channels and the AAO (Advanced Acoustic Optimisation) frame genuinely reduce turbulence noise compared to generic fans. Comes with a generous accessory kit: anti-vibration mounts (the classic brown grommets), extension cable, Y-splitter for daisy-chaining two fans on one header, screws, and the LNA adaptor. Build feels rock-solid — fibre-glass reinforced PBT blades, SSO2 bearing, and Noctua's legendary >150,000-hour MTTF rating give real confidence it'll outlast most other PC parts. ## Features - Premium quiet fan, 92x92x25 mm, 12V, 4-pin PWM, max. 2000 RPM, max. 22.8 dB(A), >150,000 h MTTF - Award-winning 92x25mm A-series fan with Flow Acceleration Channels and Advanced Acoustic Optimisation frame for superior quiet cooling performance - Ideal for 9cm CPU coolers (e.g. Noctua NH-U9(S) & NH-D9L series), compact PC cases (HTPC, ITX, Small Form Factor), replacement fan for NAS and other devices, etc. - 4-pin PWM version for automatic speed control via 4-pin PWM fan headers, broad 400-2000rpm speed range (1550rpm max. 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00RUZ059O | | Best Sellers Rank | #41 in Computer Case Fans | | Brand | Noctua | | Brand Name | Noctua | | Compatible Devices | Desktop | | Cooling Method | Air | | Customer Reviews | 4.8 out of 5 stars 4,161 Reviews | | Global Trade Identification Number | 04139052263135, 04716123315513 | | Item Dimensions L x W x H | 3.62"L x 0.98"W x 3.62"H | | Item Weight | 8 ounces | | Manufacturer | Noctua | | Material Type | Fibre-glass reinforced PBT | | Maximum Rotational Speed | 2000 RPM | | Model | NF-A9 PWM | | Noise Level | 22.8 Decibels | | Number of Items | 1 | | Part Number | NF-A9 PWM | | Power Connector Type | 4-Pin | | Product Dimensions | 3.62"L x 0.98"W x 3.62"H | | UPC | 842431014481 731215275791 | | Unit Count | 1.0 Count | | Voltage | 12 Volts | | Warranty Description | 6 year manufacturer’s warranty | ## Product Details - **Brand:** Noctua - **Compatible Devices:** Desktop - **Cooling Method:** Air - **Material:** Fibre-glass reinforced PBT - **Maximum Rotational Speed:** 2000 RPM - **Noise Level:** 22.8 Decibels - **Power Connector Type:** 4-Pin - **Product Dimensions:** 3.62"L x 0.98"W x 3.62"H - **UPC:** 842431014481 731215275791 - **Voltage:** 12 Volts ## Images ![NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown) - Image 1](https://m.media-amazon.com/images/I/81YGnt3WkSL.jpg) ![NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown) - Image 2](https://m.media-amazon.com/images/I/81Ls73P9HiL.jpg) ![NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown) - Image 3](https://m.media-amazon.com/images/I/91qyJZxtNML.jpg) ![NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown) - Image 4](https://m.media-amazon.com/images/I/91PsBrdmZOL.jpg) ![NF-A9 PWM, Premium Quiet Fan, 4-Pin (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.
