It offers a broad 400-2000 RPM speed range controlled via 4-pin PWM for precise thermal management, operates at a whisper-quiet 22.8 dB(A), and boasts a robust SSO2 bearing for over 150,000 hours of durability. Included accessories like anti-vibration mounts and low-noise adaptors make it the elite choice for silent, efficient airflow in compact and high-demand desktop setups. ## 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 iconic 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.

Review: Amazing fan - quiet and moves a lot of air! - Back Story: I have a HTPC that has a small ITX case.. which had a nice low power Haswell Refresh I3 (4170T) in it and a lowish power gfx card (GTX 1030 - only 30 watts TDP).. This was used for casual gaming and media playback of movies etc. I started to get back into gaming after about 5 years away (birth of kids etc), and decided to up my processor and gfx card.. The CPU got upgraded to a Haswell I5 (4790K), and the wattage therefore went up from 35w to 88w. Unfortunately my Scythe Kodati CPU cooler was VERY noisy trying to deal with 88 watts as it was meant for only 65w processors. Solution: The solution was buying this Noctua NF-A9 fan. I took the stock fan off the cooler (an 80mm x 10mm affair), and strapped this to it with some heat resistant rubber bands used for cooking. It increased the height of the cooler from 3.7 to 6cm, but still enough room in my case, as I had a nax height of about 10cm. I then started up the PC with its new fan on the cooler, and et voila! A lot less noisy (Kodati fan was rated as 32db max, this one at 22db max) and actually allowed me to overclock a little bit (200mhz only) due to the extra air flow (from 24 cfm to 46 cfm)! It comes with a great range of stuff in the box too - a splitter, now noise adaptor etc. Very happy with the result! Review: Perfect as always - I used these for my 6800pro Ugreen NAS. They fit perfectly and the airflow is increased but the noise is much reduced allowing me to leave it set on default. As you would expect these fans came with loads of adapters etc and were well packed. they were sturdy and the rubber corners helped with my metal chassis. The performancce of Noctua is always great and to me the the little bit more thay cos is worth it. ## 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 - 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 - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00RUZ059O | | Air Flow Capacity | 78.9 Cubic Metres Per Hour | | Best Sellers Rank | 3,837 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 80 in Thermal Management Products 145 in Fans & Cooling | | Brand | Noctua | | Compatible Devices | Desktop | | Compatible devices | Desktop | | Cooling Method | Air | | Cooling method | Air | | Customer Reviews | 4.9 out of 5 stars 4,051 Reviews | | EU Spare Part Availability Duration | 1 Years | | Global Trade Identification Number | 04139052263135, 04716123315513 | | Included Components | Camera Body | | Item Dimensions L x W x H | 25L x 92W x 92H millimetres | | Item Weight | 227 g | | Manufacturer | noctua | | Manufacturer Part Number | NF-A9 PWM | | Material | Fibre-glass reinforced PBT | | Max Rotational Speed | 2000 RPM | | Model Number | NF-A9 PWM | | Noise Level | 22.8 Decibels | | Number of Items | 1 | | Power Connector Type | 4-Pin | | Power connector type | 4-Pin | | Product Warranty | 2 year manufacturer | | Product dimensions | 25L x 92W x 92H millimetres | | UPC | 842431014481 731215275791 | | Unit Count | 1.0 count | | Voltage | 12 Volts | ## Product Details - **Air flow capacity:** 78.9 Cubic Metres Per Hour - **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:** 25L x 92W x 92H millimetres - **Voltage:** 12 Volts ## Images ![NF-A9 PWM - Image 1](https://m.media-amazon.com/images/I/81YGnt3WkSL.jpg) ![NF-A9 PWM - Image 2](https://m.media-amazon.com/images/I/81Ls73P9HiL.jpg) ![NF-A9 PWM - Image 3](https://m.media-amazon.com/images/I/91qyJZxtNML.jpg) ![NF-A9 PWM - Image 4](https://m.media-amazon.com/images/I/91PsBrdmZOL.jpg) ![NF-A9 PWM - 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.

The fan is lovely & quiet. It's very easy to install, using the screws provided in the box. There are rubber grommet things in the box; I didn't bother with them. Please note: the Dell motherboard has a five pin header; a five pin (from the Dell motherboard) to four pin (to the fan's cable) adapter cable is required. These adapters are easily obtained. The above Dell DID NOT like the fan speed reduction cable included in the box: using this cable brought about a series of beeps, a pre-boot/POST (power-on self-test) error diagnotic screen & a refusal to boot to Windows. This was easily resolved by removing the fan speed reduction cable. In short: a very quiet & relatively cheap replacement for an existing fan; ample cables & fittings provided; very nice presentation with high quality packaging. A very good product & highly recommended. ## Frequently Bought Together - Noctua NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown) - Noctua NF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, Brown) - Noctua NF-A12x25 PWM, Premium Quiet Fan, 4-Pin (120mm, Brown) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/47874224-nf-a9-pwm](https://www.desertcart.ie/products/47874224-nf-a9-pwm) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-07-09*
