Featuring advanced aerodynamic design elements, PWM speed control from 300 to 1500 RPM, and anti-vibration accessories, it delivers superior cooling performance for cases, CPU coolers, and radiators. Trusted for reliability with premium-grade SSO2 bearings and comprehensive safety certifications, it’s the go-to choice for professionals demanding silent yet powerful thermal management. ## Description Product Description Succeeding the award-winning NF-A14 and building on the technological innovations of the ground-breaking NF-A12x25, the NF-A14x25 G2 is Noctua’s next-generation square-frame 140mm flagship model: Made from Sterrox LCP, its highly optimised Progressive-Bend impeller with winglets, Flow Acceleration Channels and Centrifugal Turbulator hub combined with a tip-clearance of only 0.7mm allow the NF-A14x25 G2 to further improve its predecessor’s renowned quiet cooling performance. Like the NF-A14 and NF-A12x25, it is a true all-rounder that yields superb results in all types of usage, regardless of whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, static pressure demanding scenarios such as on heatsinks and water cooling radiators. For application-specific optimisation, the NF-A14x25 G2 comes with an NA-AVG2-LR anti-vibration gasket pre-installed to create a tighter seal on radiators. Additionally, its AAO (Advanced Acoustic Optimisation) frame can be combined with the optional NA-IS1-14 inlet spacer, which can help to achieve superior suction acoustics and flow rates in challenging intake configurations. The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 1500 to 1250rpm. Its ultra-low-loss etaPERF motor with Smooth Commutation Drive 2 technology doesn’t only provide unprecedented energy efficiency and running smoothness, but thanks to the new SupraTorque feature, it can also leverage extra torque headroom to keep the fan at its desired speed when working against back pressure, thereby ensuring even better performance on heatsinks and radiators. Topped off with Noctua’s reference-class SSO2 bearing and a rich bundle of accessories, the NF-A14x25 G2 is a premium-quality product through and through. Its superior performance, comprehensive feature set, cutting-edge construction and state-of-the-art materials set a new standard within Noctua’s portfolio and make it an elite choice for the most discerning demands. Progressive-Bend impeller The NF-A14x25 G2 features a unique Progressive-Bend impeller with Flow Acceleration Channels and winglets. Its nine blades are swept backwards close to the hub and progressively bent forward further out. Working in tandem with the Centrifugal Turbulator hub, this design not only helps to push more air towards the outer blade areas where efficiency is higher but also assures maximum lift and near uniform loading across the entire blade span. Centrifugal Turbulator hub Acting as a turbulator, the new Centrifugal Turbulator hub design improves flow attachment in the hub region. At the same time, it’s centrifugal driving motion pushes air outwards from the hub area where efficiency is low due to the slow rotational speed towards the outer, high-efficiency zones of the blades, thereby increasing overall efficiency by optimising fluid distribution across the impeller area. SSO2 Bearing The NF-A14x25 G2 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. Ultra-tight tip clearance The NF-A14x25 G2 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.7mm. This highly ambitious design sets a new benchmark for 140mm fans and helps the NF-A14x25 G2 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame. Scope of delivery NA-RC16 Low-Noise Adaptor (L.N.A.) NA-YC1 4-pin PWM splitter cable NA-EC1 30cm extension cable 4x NA-AV2 anti-vibration mounts NA-AVG2-LR anti-vibration gasket 4x NA-AVP1-LR load-relief anti-vibration pads Fan screws Highly optimised P/Q curve for all applications The NF-A14x25 G2’s sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A14x25 G2 is a true jack-of-all-trades with excellent performance in both static pressure and airflow demanding applications. Review: Quietest 140MM Fan I've ever used / heard. - Swapped my case to Antec Flux and fit 4x NF-A14x25 G2 PWM Sx2-PP at the same time, 3x at the front and 1 in the rear, used 1 NF-A14x25 for PSU shroud intake, really impressed with how you can't hear these fans under 800 RPM, even at 400 RPM the amount of air they move is impressive, they can be heard once you start increasing the RPM however with the amount of air they move I don't have to have them above 600 RPM. As in Noctua fashion you get a very nice unboxing experience and they come with all the usual accessories you'd expect, one thing to note is by default the fans ship with the radiator rubber gasket preinstalled unlike previous Noctua fans that come with the 4x corners preinstalled so you'll have to swap them over. Expensive when compared to other fans on the market however I'm more than happy with my purchase. Review: Inaudible above my system hum at 55%. - I like the performance of these fans. I am after mostly quiet but occasional power. The amount of research & development that went into these fans is impressive. I used them to replace my NF-A14s when one of them died (within the six year warranty). I have the same level of system noise (aka none with headphones on) and my coolant temperature is lower; which with modern CPUs and GPUs means more performance. I have my fans set to ramp up @36'c water temperature (summer time) and have 10'c to go, at virtual silence. I bought a spacer: Noctua NA-IS1-14 Sx2; and have used it on one of my 3 140mm radiator fans as space permitted. I've watched a youtube review which said that the fans can perform better with the spacer in this pull scenario with a radiator. Did I mention the six year warranty? ## Features - Next-gen 140x25mm design for unprecedented quiet cooling performance in both high airflow and high static pressure applications: ideal as a PC case fan, on CPU coolers and water cooling radiators! - State-of-the-art engineering (Progressive-Bend impeller with winglets and Centrifugal Turbulator, Flow Acceleration Channels, AAO frame) and construction (Sterrox LCP, ultra-tight tip clearance) - 4-pin PWM version for automatic speed control via 4-pin PWM motherboard fan headers, 300-1500rpm speed range (near-silent at idle, powerful under load), fan stops at 0% PWM (semi-passive option) - Includes anti-vibration mounts, 14cm anti-vibration gasket for tighter seal on radiators, fan screws, Low-Noise Adaptor (LNA), extension cable and splitter cable for running two PWM fans on the same header - Trusted Noctua quality with premium-grade SSO2 bearing (MTTF > 150,000 h), safety certifications from UL and TÜV, protected against reverse polarity, over voltage and over current (short-circuits) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DDY14DQD | | Best Sellers Rank | 7,873 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 36 in Electronic Cooling Fans | | Brand | Noctua | | Compatible Devices | Desktop | | Cooling Method | Air | | Cooling method | Air | | Country Of Origin | Taiwan | | Customer Reviews | 4.8 out of 5 stars 469 Reviews | | Global Trade Identification Number | 09010018100617 | | Included Components | NF-A14x25 G2 PWM | | Item Dimensions L x W x H | 14L x 2.5W x 14H centimetres | | Item Weight | 0.36 Kilograms | | Manufacturer | Noctua | | Manufacturer Part Number | NF-A14x25 G2 PWM | | Material | Sterrox LCP | | Max Rotational Speed | 1500 RPM | | Model Number | NF-A14x25 G2 PWM | | Noise Level | 24.8 Decibels | | Number of Items | 1 | | Power Connector Type | 4-Pin | | Power connector type | 4-Pin | | Product Warranty | 1 Year Manufacturer | | Product dimensions | 14L x 2.5W x 14H centimetres | | Unit Count | 1.0 count | | Voltage | 12 Volts | | Wattage | 2.28 watts | ## Product Details - **Brand:** Noctua - **Compatible devices:** Desktop - **Cooling method:** Air - **Material:** Sterrox LCP - **Maximum rotational speed:** 1500 RPM - **Noise level:** 24.8 Decibels - **Power connector type:** 4-Pin - **Product dimensions:** 14L x 2.5W x 14H centimetres - **Voltage:** 12 Volts - **Wattage:** 2.28 watts ## Images ![Noctua NF-A14x25 G2 PWM, Premium-Quality Quiet 140mm PC Fan, 4-pin (Brown) - Image 1](https://m.media-amazon.com/images/I/81Sggn39-9L.jpg) ![Noctua NF-A14x25 G2 PWM, Premium-Quality Quiet 140mm PC Fan, 4-pin (Brown) - Image 2](https://m.media-amazon.com/images/I/714HGkl7kQL.jpg) ![Noctua NF-A14x25 G2 PWM, Premium-Quality Quiet 140mm PC Fan, 4-pin (Brown) - Image 3](https://m.media-amazon.com/images/I/81KqY7-7oNL.jpg) ![Noctua NF-A14x25 G2 PWM, Premium-Quality Quiet 140mm PC Fan, 4-pin (Brown) - Image 4](https://m.media-amazon.com/images/I/71tkBHZ7axL.jpg) ![Noctua NF-A14x25 G2 PWM, Premium-Quality Quiet 140mm PC Fan, 4-pin (Brown) - Image 5](https://m.media-amazon.com/images/I/711bn922bhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quietest 140MM Fan I've ever used / heard. *by R***G on 21 October 2024* Swapped my case to Antec Flux and fit 4x NF-A14x25 G2 PWM Sx2-PP at the same time, 3x at the front and 1 in the rear, used 1 NF-A14x25 for PSU shroud intake, really impressed with how you can't hear these fans under 800 RPM, even at 400 RPM the amount of air they move is impressive, they can be heard once you start increasing the RPM however with the amount of air they move I don't have to have them above 600 RPM.
