This article covers be quiet! ケースファン PURE WINGS 3 140mm White PWM High Speed 1.

Overview

The be quiet! Pure Wings 3 140mm White PWM High Speed is a 140mm case fan designed for balanced airflow and low noise. With a maximum speed of 1,800 RPM and a noise level of 30.5 dBA, it delivers strong cooling performance while remaining quiet enough for daily use. The rifle bearing ensures a lifespan of about 80,000 hours, making it a durable choice for long-term builds. The white color scheme fits well in light-themed PC builds, and the fan is suitable for both case ventilation and radiator mounting. This model offers excellent value in the mid-range segment, backed by be quiet!'s reputation for quality.

Compatibility Guide

This fan has standard 140mm dimensions (140x140x25mm) and fits all cases and radiators with 140mm mounting holes. It uses a 4-pin PWM connector, allowing automatic speed control via the motherboard. For radiator use, the closed-loop motor technology maintains consistent RPM even under backpressure, ensuring effective heat dissipation. Note that a 120mm fan alternative is available if your case only supports 120mm fans. Both intake and exhaust orientations are supported.

Product Info

The be quiet! Pure Wings 3 140mm White PWM High Speed debuted in 2023 as a mid-range cooling solution. Priced at approximately ¥2,000, it offers excellent value from a reputable German brand. The closed-loop motor design keeps fan speed stable regardless of airflow resistance, particularly beneficial on radiators and heatsinks. The warranty is typically 3 years (please verify with retailer). A black version is also available for darker builds.

Best Use Cases

Ideal for white-themed PC builds where matching color aesthetics matter, this fan adds a clean look without sacrificing performance. It is also a great choice for users mounting fans on radiators, as the high static pressure design and stable motor maintain cooling efficiency even under restriction. Budget-conscious builders looking for a reliable, quiet fan from a trusted brand will appreciate the cost-to-performance ratio. Suitable for gaming PCs, productivity rigs, and general cooling upgrades.

Things to Consider

The High Speed variant operates at up to 1,800 RPM, which is louder than the standard Pure Wings 3 (1,350 RPM) under full load. If absolute silence is your priority, consider the Low Speed version. Also, ensure your case supports 140mm fans; many smaller cases only accept 120mm. The rifle bearing is durable but not as acoustically refined as fluid or magnetic levitation bearings used in premium fans. However, at this price point, the balance of longevity and noise is commendable.
