Featuring a unique speed-offset design to prevent acoustic interference, advanced aerodynamic impellers, and durable Sterrox LCP construction, these fans excel in push-pull radiator setups and case cooling. With a max speed of 1500 RPM, noise levels as low as 24.8 dB, and a 150,000-hour rated SSO2 bearing, this kit ensures reliable, silent performance backed by comprehensive mounting accessories. ## 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 | #186,149 in Computers & Accessories (See Top 100 in Computers & Accessories) #1,009 in Case Fans | | Brand Name | Noctua | | Compatible Devices | Desktop | | Cooling Method | Air | | Customer Reviews | 4.8 4.8 out of 5 stars (363) 4.8 out of 5 stars | | Item Dimensions L X W X H | 14L x 14W x 2.5H Centimeters | | Item Weight | 0.68 Kilograms | | Manufacturer | Noctua | | Material Type | Sterrox LCP | | Max Rotational Speed | 1500 RPM | | Model Number | NF-A14x25 G2 PWM Sx2-PP | | Noise Level | 24.8 Decibels | | Number Of Items | 2 | | Part Number | NF-A14x25 G2 PWM Sx2-PP | | Power Connector Type | 4-Pin | | Unit Count | 2.0 Count | | Voltage | 12 Volts | ## Product Details - **Brand:** Noctua - **Cooling Method:** Air - **Power Connector Type:** 4-Pin - **Product Dimensions:** 14L x 14W x 2.5H Centimeters - **Voltage:** 12 Volts ## Images ![Noctua 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) ![Noctua 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) ![Noctua 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) ![Noctua 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) ![Noctua 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 ### ⭐⭐⭐⭐⭐ Great silent performance *by on Reviewed in the Netherlands 3 December 2025* Best fans and most quiet fans there are. ### ⭐⭐⭐⭐⭐ worth the price *by on Reviewed in Japan 9 May 2026* quiet and efficient ### ⭐⭐⭐⭐⭐ Quiet, powerful, pricey *by on Reviewed in Singapore 7 May 2026* Quiet, hope it lasts as long as the previous Noctual A-series fansPretty pricey though ## 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?
