Featuring a broad 1000-5000 RPM speed range controlled via 4-pin PWM, it delivers efficient airflow with minimal noise at just 19.6 dB(A). Built with advanced acoustic optimization and durable materials, it offers over 150,000 hours of reliable operation, complete with anti-vibration mounts and versatile connectors for seamless installation. ## Description Product description Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 is an award-winning, premium-quality quiet fan in size 40x10mm. 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 as well as an OmniJoin Adaptor Set for easy connection to proprietary fan headers. 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-A4x10 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-A4x10 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 mounting systems and fan clips used on heatsinks. 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. Reduced motor hub size Thanks to its streamlined, compact motor design, the NF-A4x10's motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10's superior airflow and pressure performance. Review: high quality, low airlow, quiet. - Beautiful piece of engineering. And the packaging... Wow. Speechless. They've included everything you might need. The airflow is weak though, but what would you expect from the fan of this size. Oh yeah! And it's super quiet. Review: Moves Plenty of Air & Extremely Quiet - Used to replace original Asus ROG Strix Z390-E chip set fan. Fan is almost silent and moves plenty of air. My opinion, Noctua fans are the best. All case fans have been replaced with Noctua's fans and no complaints. ## Features - Premium quiet fan, 40x40x10 mm, 12V, 4-pin PWM, max. 5000 RPM, max. 19.6 dB(A), >150,000 h MTTF - Award-winning A-series design with Flow Acceleration Channels and Advanced Acoustic Optimisation frame for superior quiet cooling performance - 40x10mm size ideal for 1U servers or replacing fans in network and storage equipment (routers, switches, NAS etc.) or other devices such as DVRs - 4-pin PWM version for automatic speed control via 4-pin PWM fan headers, broad 1000-5000rpm speed range (3700rpm max. with supplied Low-Noise Adaptor) - Includes anti-vibration mounts, fan screws, Low-Noise Adaptor, extension cable and OmniJoin adaptor set for connecting the fan to proprietary fan headers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DXRNYNX | | Best Sellers Rank | #72 in Computer Case Fans | | Brand | Noctua | | Brand Name | Noctua | | Compatible Devices | Desktop | | Cooling Method | Air | | Customer Reviews | 4.8 out of 5 stars 1,947 Reviews | | Global Trade Identification Number | 00841501110443, 09010018100440 | | Included Components | Noctua NF-A4x10 PWM, High-end Silent Fan | | Item Dimensions L x W x H | 1.57"L x 1.57"W x 0.39"H | | Item Type Name | Fan | | Item Weight | 0.17 Kilograms | | Manufacturer | Noctua | | Material Type | Fibre-glass reinforced PBT | | Maximum Rotational Speed | 5000 RPM | | Model | NF-A4x10 PWM | | Noise Level | 19.6 Decibels | | Number of Items | 1 | | Part Number | NF-A4x10 PWM | | Power Connector Type | 4-Pin | | Product Dimensions | 1.57"L x 1.57"W x 0.39"H | | UPC | 841501110443 | | 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:** 5000 RPM - **Noise Level:** 19.6 Decibels - **Power Connector Type:** 4-Pin - **Product Dimensions:** 1.57"L x 1.57"W x 0.39"H - **UPC:** 841501110443 - **Voltage:** 12 Volts ## Images ![Noctua NF-A4x10 PWM, Premium Quiet Fan, 4-Pin (40x10mm, Brown) - Image 1](https://m.media-amazon.com/images/I/81ud+v9ghlL.jpg) ![Noctua NF-A4x10 PWM, Premium Quiet Fan, 4-Pin (40x10mm, Brown) - Image 2](https://m.media-amazon.com/images/I/81VO3TY5o2L.jpg) ![Noctua NF-A4x10 PWM, Premium Quiet Fan, 4-Pin (40x10mm, Brown) - Image 3](https://m.media-amazon.com/images/I/91q4VBG-wuL.jpg) ![Noctua NF-A4x10 PWM, Premium Quiet Fan, 4-Pin (40x10mm, Brown) - Image 4](https://m.media-amazon.com/images/I/91E+f0eh0WL.jpg) ![Noctua NF-A4x10 PWM, Premium Quiet Fan, 4-Pin (40x10mm, Brown) - Image 5](https://m.media-amazon.com/images/I/71hMKYK9MpL.jpg) ## Questions & Answers **Q: What's the cfm?** A: This fan is rated at 8.9m³/h and 6.6 m³/h with the LNA, this converts to 5.23834215487808 CFM and 3.88461328339273 CFM with the LNA **Q: Will the fan operate off a 2 pin 12V DC supply?** A: Sure, when the PWM has a pull up, this means the FAN will run at 100%. **Q: Can this fan be used in place of the noctua nf-a4x10 flx?** A: There is no reason why not, but do not expect to get the RPMs as low as you can using a PWM signal be aware this model can get a little louder than the flx version as the max fan speed is higher, but that does come with more airflow and static pressure **Q: can I run this off a 12v fan header on my motherboard/fan splitter?** A: yes, you can use as many splitters as you like, just check how many amps your board header maxes out at and add up your fans current draw, this fan is specked at 40 milliamp, 1000 milliamp = 1 amp ## Customer Reviews ### ⭐⭐⭐⭐⭐ high quality, low airlow, quiet. *by T***Y on January 29, 2026* Beautiful piece of engineering.

I did have to use zip ties in order to attach it. But that is not really a surprise. ## Frequently Bought Together - Noctua NF-A4x10 PWM, Premium Quiet Fan, 4-Pin (40x10mm, Brown) - Noctua NF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, 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.vu/products/71150024-noctua-nf-a4x10-pwm-premium-quiet-fan-4-pin-40x10mm](https://www.desertcart.vu/products/71150024-noctua-nf-a4x10-pwm-premium-quiet-fan-4-pin-40x10mm) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
