## Overview

The Noctua NF-A14x25 G2 PWM Sx2-PP is a premium dual 140mm fan set engineered for push-pull and side-by-side configurations. Featuring a unique ±25 RPM speed offset to eliminate acoustic interference, ultra-quiet operation at 24.8 dB, and advanced aerodynamic design with Sterrox LCP construction, these fans deliver exceptional airflow and durability. Complete with anti-vibration accessories and Low-Noise Adaptors, they ensure professional-grade cooling performance and silent operation for high-end desktop systems.

## 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: Produkt pierwsza klasa. - Noctua, cicha, nieźle wieje, niezniszczalna, brzydka. Fajnie że w pudełku są wszystkie potrzebne dodatki. Niestety bardzo droga.
