Overview

The be quiet! Pure Wings 3 140mm Quiet Case Fan delivers silent operation and balanced airflow for your PC. With a maximum speed of 1500 RPM and a noise level of just 21.9 dBA, it keeps your system cool without distracting noise. The fan features seven airflow-optimized blades and a high-quality rifle bearing rated for 80,000 hours of operation, ensuring long-term reliability. Optimized for radiator use, this fan fits seamlessly into both air-cooled and liquid-cooled builds. It occupies the mid-range silent fan segment, offering a compelling balance of performance, quietness, and durability.

Compatibility Guide

The fan is 140mm in size and requires a 140mm fan mount on your case. It cannot be installed in 120mm mounts without an adapter (not included). The 4-pin PWM connector supports automatic speed control on most modern motherboards; 3-pin headers will run the fan at full speed. Standard 25mm thickness makes it compatible with most 240mm, 280mm, and 360mm radiators. Ensure your case has enough clearance for 140mm fans, especially if using push-pull configurations.

Product Info

Released in late 2023, the Pure Wings 3 140mm is priced around ¥6,362 on Japan. It carries a 3-year warranty from be quiet! (registration recommended). The fan targets the mid-range market, competing with Noctua NF-A14 and ARCTIC P14. Its key differentiators are the long-life rifle bearing and optimized frame for radiator use, providing quiet yet effective cooling.

Best Use Cases

Ideal for silent gaming PCs: at idle or low load, the fan runs at very low RPM (as low as 200 RPM reportedly) with minimal noise, and ramps up to 1500 RPM under heavy load to maintain temperatures. Perfect for water-cooling radiators: the frame design maximizes static pressure, making it effective for liquid cooling setups. Also suitable for office or HTPC builds where noise must be kept to a minimum – the Pure Wings 3 excels at quiet operation without compromising airflow.

Things to Consider

The 140mm size limits compatibility – you cannot use it in 120mm-only cases. If you need maximum airflow, consider the high-speed version (Pure Wings 3 140mm High Speed). No RGB lighting is included, so users wanting visual effects will need to look elsewhere. At full speed, the fan is slightly louder than some premium competitors like Noctua NF-A14, but in the low-to-mid range it is quieter. Ensure your motherboard supports PWM if you want automatic speed control; otherwise, the fan will always run at max RPM.
