Engineered with advanced airflow technologies and ultra-quiet operation at 24.8 dB, these fans excel in push-pull and side-by-side configurations, ideal for 280mm radiators and high-performance PC cooling. Included anti-vibration accessories and premium Sterrox LCP materials ensure durability and silent, efficient cooling for professional-grade desktop setups. ## Description The NF-A14x25 G2 PWM Sx2-PP is a set of two NF-A14x25 G2 PWM square-frame 140mm fans that are offset in speed, which can be beneficial in push-pull operation as well as in situations where two fans are operating side by side, such as in case cooling applications or on 280mm water cooling radiators. When two fans are running at almost the same, constant speed in a push-pull configuration or, albeit to a lesser extent, side by side, their acoustic interaction can lead to undesirable harmonic phenomena such as intermittent vibrations or periodic humming due to interference, which can be heard as beat frequencies. Therefore, the two NF-A14x25 G2 PWM fans contained in the Sx2-PP set are slightly offset in speed (+/- ~25rpm) in order to avoid such phenomena. This fine-tuning is made possible by the fans’ novel etaPERF motor and its NE-FD6 driver IC that achieves extremely precise speed control and, thanks to its SupraTorque feature, can leverage extra torque headroom to keep the exact desired speed even when working against significant flow resistance such as on water cooling radiators and heatsinks. With one fan running ~25rpm slower (PPA) and one ~25rpm faster (PPB), the overall cooling performance can be kept the same while efficiently preventing intermittent vibrations or periodic humming. Since the perception of beat frequencies can vary depending on psychoacoustic preferences, users can easily further optimise acoustics by slowing the PPA fan down a little more through PWM control or the supplied Low-Noise-Adaptor, which will result in an even smoother sound signature due to the increased offset. ## Features - Dedicated dual fan set with two NF-A14x25 G2 PWM 140x25mm fans that are slightly off-set in speed (+/- ~25rpm) in order to avoid undesired acoustic interaction phenomena - 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) - Ideal choice for push-pull applications as well as situations where two fans are operating side by side (280mm water cooling radiators, case intake or exhaust fans, etc.) - Includes anti-vibration mounts, anti-vibration gaskets for tighter seal on radiators, fan screws, Low-Noise Adaptors (LNA), extension cables and y-cable for running two 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 | B0DDXRD5RK | | Best Sellers Rank | 9,573 in Business, Industry & Science (See Top 100 in Business, Industry & Science) 124 in Thermal Management Products 214 in Fans & Cooling | | Brand | Noctua | | Compatible Devices | Desktop | | Cooling Method | Air | | Country Of Origin | Taiwan | | Customer Reviews | 4.8 4.8 out of 5 stars (354) 4.8 out of 5 stars | | Included Components | NF-A14x25 G2 PWM Sx2-PP | | Item Dimensions L X W X H | 14L x 14W x 2.5H centimetres | | Item Weight | 0.68 Kilograms | | Manufacturer | Noctua | | Manufacturer Part Number | NF-A14x25 G2 PWM Sx2-PP | | Material | Sterrox LCP | | Max Rotational Speed | 1500 RPM | | Model Number | NF-A14x25 G2 PWM Sx2-PP | | Noise Level | 24.8 Decibels | | Number Of Items | 2 | | Power Connector Type | 4-Pin | | Product Warranty | 1 Year Manufacturer | | Unit Count | 2.0 count | | Voltage | 12 Volts | ## Product Details - **Brand:** Noctua - **Compatible devices:** Desktop - **Cooling method:** Air - **Manufacturer:** Noctua - **Material:** Sterrox LCP - **Maximum rotational speed:** 1500 RPM - **Noise level:** 24.8 Decibels - **Power connector type:** 4-Pin - **Product dimensions:** 14L x 14W x 2.5H centimetres - **Voltage:** 12 Volts ## Images ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm | High Airflow & Static Pressure, Low-Noise 25mm Thick Fans, Speed-Offset Dual Kit, for Coolers/Radiators/Cases, 1500rpm 4-Pin - Image 1](https://m.media-amazon.com/images/I/81CxumffFML.jpg) ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm | High Airflow & Static Pressure, Low-Noise 25mm Thick Fans, Speed-Offset Dual Kit, for Coolers/Radiators/Cases, 1500rpm 4-Pin - Image 2](https://m.media-amazon.com/images/I/81KqY7-7oNL.jpg) ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm | High Airflow & Static Pressure, Low-Noise 25mm Thick Fans, Speed-Offset Dual Kit, for Coolers/Radiators/Cases, 1500rpm 4-Pin - Image 3](https://m.media-amazon.com/images/I/71euTmmyxYL.jpg) ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm | High Airflow & Static Pressure, Low-Noise 25mm Thick Fans, Speed-Offset Dual Kit, for Coolers/Radiators/Cases, 1500rpm 4-Pin - Image 4](https://m.media-amazon.com/images/I/712cYPr6KgL.jpg) ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm | High Airflow & Static Pressure, Low-Noise 25mm Thick Fans, Speed-Offset Dual Kit, for Coolers/Radiators/Cases, 1500rpm 4-Pin - Image 5](https://m.media-amazon.com/images/I/711bn922bhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Whisper quiet and powerful *by on Reviewed in the United Kingdom 29 January 2026* I read up on these as I wanted a silent PC build. The Fractal case I bought was a little noisy for my taste so decided to replace the in case fans with these and what a difference it made! Temperature wise the CPU dropped around 5 degrees and noise wise they can barely be heard under my desk. They didn't replace the CPU fan directly, so this is purely configuring the ambient air flow so very happy with the results. ### ⭐⭐⭐⭐⭐ Best fans *by on Reviewed in the United Kingdom 2 March 2026* These are great computer fans, very efficient and very quiet. If you don't care about price or appearance, buy them, because there are no better ones on the market. ### ⭐⭐⭐⭐⭐ Premium cooling that can't be beat *by on Reviewed in the United Kingdom 30 November 2025* Works perfectly. Noctua are my go-to for anything air cooling. The amount of air that they can push is amazing, it's like the power of a proper room fan. Moving to these from my previous arctic 212 120mm fans, I've seen ~10c improvements, this is from a 5 fan 120mm setup to a noctua 5 fan setup, with 4 140mm fans (these ones) and a nf-a12x25 G2 at the rear. Noctua aren't cheap, but you definitely get what you pay for. ## Frequently Bought Together - Noctua NF-A14x25 G2 PWM Sx2-PP, Dual Fan Set for Push-Pull and Side-by-Side Applications (Brown) - Noctua NF-A14x25 G2 PWM, Premium-Quality Quiet 140mm PC Fan, 4-pin (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.tn/products/660909881-nf-a14x25-g2-pwm-sx2-pp-high-performance-quiet-fans](https://www.desertcart.tn/products/660909881-nf-a14x25-g2-pwm-sx2-pp-high-performance-quiet-fans) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-02*
