## Overview

The Noctua NF-A14x25 G2 PWM Sx2-PP is a premium dual 140mm fan set designed for push-pull and side-by-side applications, featuring speed-offset operation to prevent acoustic interference. Engineered with advanced aerodynamic features like Progressive-Bend impellers, ultra-tight tip clearance, and durable Sterrox LCP material, these fans deliver exceptional airflow and static pressure at a whisper-quiet 24.8 dB noise level. Included accessories such as anti-vibration mounts, Low-Noise Adaptors, and splitter cables make installation effortless, ensuring reliable, long-lasting cooling performance for demanding PC builds.

## Description

Product 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. Dual fan set for push-pull and side-by-side usage Bundling two NF-A14x25 G2 PWM fans that are speed-offset by +/- ~25rpm in order to avoid undesired acoustic interaction phenomena, the Sx2-PP set is the ideal choice for push-pull configurations as well as situations where two fans are operating side by side such as on 280mm radiators or in typical case cooling applications. 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. 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 NF-A14x25 G2 PWM PPA NF-A14x25 G2 PWM PPB 2x NA-RC16 Low-Noise Adaptor (L.N.A.) NA-YC1 4-pin PWM splitter cable 2x NA-EC1 30cm extension cable 8x NA-AV2 anti-vibration mounts 2x NA-AVG2-LR anti-vibration gasket for water cooling radiators 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: Whisper quiet and powerful - 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.
Review: Best fans - 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 U***E on 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.
