This article covers be quiet! PURE WINGS 3 140mm PWM ハイスピードファン.

Overview

The be quiet! PURE WINGS 3 series has earned a strong reputation among PC builders for balancing silent operation with effective cooling performance. This 140mm PWM High Speed variant pushes the maximum RPM to 1,800, making it suitable for demanding thermal scenarios. Its closed-loop motor technology ensures stable rotation speeds regardless of airflow resistance, a key advantage when mounted on radiators or heatsinks. Equipped with a rifle bearing rated for approximately 80,000 hours of operation, this fan is built for longevity. The 140mm form factor provides a larger blade surface area compared to 120mm fans, enabling higher airflow at lower noise levels under normal operating conditions. Positioned in the mid-to-high-end segment of the case fan market, the PURE WINGS 3 High Speed offers a compelling mix of be quiet!'s signature noise dampening and the higher static pressure needed for restrictive cooling setups. It is a versatile choice for enthusiasts who want reliable performance without excessive noise.

Compatibility Guide

This fan is designed for 140mm mounting points commonly found in mid-tower and full-tower PC cases. It uses a standard 4-pin PWM connector, allowing the motherboard to dynamically control fan speed based on temperature readings. It will also work with 3-pin headers, but PWM speed regulation requires a 4-pin connection. The fan dimensions are 140mm x 140mm x 25mm, which is the standard thickness for case fans. Most cases with 140mm support will accommodate this without clearance issues, but it is always wise to verify available space, especially when using thick radiators or large CPU coolers.

Product Info

Released in late 2023, the be quiet! PURE WINGS 3 140mm PWM High Speed fan targets the mid-to-high-end segment of the cooling market. It is designed for users who need reliable static pressure for radiators and heatsinks while keeping noise levels in check. Key specifications include a maximum rotational speed of 1,800 RPM, a noise output of 30.5 dBA, and a maximum power draw of 6W at 12V. The fan weighs approximately 200g. It comes with a standard 3-year manufacturer warranty and is available through major online retailers like .

Best Use Cases

This fan is an excellent choice for water cooling radiators. The closed-loop motor technology maintains consistent RPM even under the backpressure created by dense radiator fins, ensuring steady cooling performance without unexpected slowdowns. It is also well-suited for builders who prioritize quiet operation but still need strong airflow. The be quiet! brand heritage in noise reduction, combined with the High Speed model's 1,800 RPM capability, provides a balanced solution for systems that run both idle and under load. For users seeking a long-term, low-maintenance setup, the rifle bearing's 80,000-hour lifespan means fewer replacements over the life of the PC. This makes it a practical choice for workstations or home servers that run continuously.

Things to Consider

As a High Speed variant, this fan produces slightly more noise than the standard PURE WINGS 3 (1,500 RPM) model. If absolute silence is your top priority, consider the standard or Low Speed versions instead. The 140mm size may not fit in compact cases or those with limited clearance. Always check your case specifications for 140mm fan support before purchasing. PWM control quality can vary between motherboards. Some boards may not provide smooth speed transitions, requiring manual tuning via BIOS or software utilities to achieve the desired fan curve. Additionally, while the fan is rated for 30.5 dBA at maximum speed, actual noise levels depend on case acoustics and mounting conditions.
