Featuring a unique ±25 RPM speed offset to prevent acoustic interference, advanced aerodynamic design, and ultra-quiet operation at 24.8 dB, these fans deliver exceptional cooling performance for high-demand PC builds and water cooling radiators. Built with durable Sterrox LCP material and backed by Noctua’s renowned quality, this set includes all necessary accessories for vibration-free, easy installation. ## 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. Review: Great silent performance - Best fans and most quiet fans there are. Review: The succ, the silence, the gains! - 1. They can be whisper quiet and do a decent job; although, I'd recommend setting a fan curve for optimal balance between airflow during peak CPU utilization and quiet during light workloads. 2. They are effective at airflow and pressure making them a true jack of all trades. 3. Significantly more powerful than the 120mm fans but at the cost of a bit of noise when ramping up but bottom end is still whisper quiet. I'm currently running these in a push config on a water-cooled CPU radiator. Mind you I barely notice these fans even with open back headphones, massively better than the ones that came with the radiator. ## 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 | #89,289 in Computers & Accessories ( See Top 100 in Computers & Accessories ) #456 in Case Fans | | Brand | Noctua | | Brand Name | Noctua | | Compatible Devices | Desktop | | Cooling Method | Air | | Country of Origin | USA | | Customer Reviews | 4.9 out of 5 stars 346 Reviews | | 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 | | Product Dimensions | 14L x 14W x 2.5H Centimeters | | 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 ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm - Image 1](https://m.media-amazon.com/images/I/81CxumffFML.jpg) ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm - Image 2](https://m.media-amazon.com/images/I/81KqY7-7oNL.jpg) ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm - Image 3](https://m.media-amazon.com/images/I/71euTmmyxYL.jpg) ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm - Image 4](https://m.media-amazon.com/images/I/712cYPr6KgL.jpg) ![NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm - Image 5](https://m.media-amazon.com/images/I/711bn922bhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great silent performance *by S***. on 3 December 2025* Best fans and most quiet fans there are. ### ⭐⭐⭐⭐⭐ The succ, the silence, the gains! *by B***E on 3 September 2025* 1.
