Quiet 140mm Noctua NF-A14x25r G2 PWM PC Fan, 4-pin (Brown)

This is a high-performance cooling solution designed for use in personal computers, particularly for CPU coolers that require a 140mm fan. The fan is engineered to provide excellent airflow while maintaining a quiet operation, making it ideal for users who prioritize both cooling efficiency and noise reduction in their builds. It features a next-generation round-frame design that enhances its performance on specific CPU cooler models like the NH-D15, NH-D15S, or NH-U14S series. The fan is built with advanced materials and technologies to ensure durability and reliability over time.

The fan offers a wide range of speed control through its 4-pin PWM interface, allowing it to adjust its performance based on the system's thermal needs. It can operate between 300 and 1500 RPM, providing near-silent operation at idle and powerful cooling under heavy loads. Additionally, the fan can be completely turned off when the PWM signal is at 0%, offering a semi-passive cooling option for users who want to minimize noise even further. This makes it suitable for both high-performance gaming rigs and quiet office setups.

The fan comes with several accessories to ensure easy installation and optimal performance. These include anti-vibration mounts, fan screws, a Low-Noise Adaptor (LNA), an extension cable, and a y-cable for running two PWM fans on the same header. These components help in reducing noise and ensuring compatibility with various motherboard headers. The fan is also built with a premium-grade SSO2 bearing that ensures long life and smooth operation, backed by safety certifications from UL and TÜV.

The design of the fan includes features like Progressive-Bend impeller with winglets, Centrifugal Turbulator, and Flow Acceleration Channels, all of which contribute to its superior airflow and noise reduction capabilities. It is constructed using Sterrox LCP material and has ultra-tight tip clearance to prevent any unnecessary vibrations or noise. The fan is also protected against reverse polarity, overvoltage, and overcurrent (short-circuits), ensuring safe operation under various conditions.
