This article covers be quiet! ケースファン PURE WINGS 3 120mm PWM High Speed 2.

Overview

The be quiet! PURE WINGS 3 120mm PWM High Speed is a 120mm case fan that delivers up to 2,100 RPM while keeping noise levels at a modest 30.9 dBA. It supports PWM control for precise speed tuning via the motherboard, making it versatile for various cooling scenarios. The closed-loop motor technology maintains stable rotation even against airflow resistance, which is especially beneficial when mounted on heatsinks or radiators. With a rifle bearing rated for 80,000 hours of operation, this fan offers long-term reliability for daily use. The high-speed variant prioritizes cooling performance over absolute silence, positioning it as a balanced mid-range option in be quiet!'s lineup.

Compatibility Guide

Standard 120mm fan dimensions (120x120x25mm) fit most PC cases with 120mm mounts. 4-pin PWM connector enables automatic fan speed control when plugged into a motherboard 4-pin header. Can also run on 3-pin headers, but PWM functionality is lost; DC voltage control or fixed speed will apply. Compatible with standard 120mm fan screw holes on CPU coolers and radiators. * Includes four mounting screws and a quick manual; rubber anti-vibration mounts are not included but can be added separately.

Product Info

The fan was released in late 2023 with a typical retail price around ¥1,800-¥2,200 in Japan. It is sold as an official be quiet! product with a 3-year manufacturer warranty. In the market, it sits at the mid-range tier, offering a good compromise between airflow, static pressure, and noise – ideal for users who want reliable cooling without spending a premium on top-tier silent fans.

Best Use Cases

Balanced performance for desktop PCs: The PWM control allows near-silent operation at low loads and effective cooling under heavy loads, making it suitable for general computing, productivity, and gaming. Auxiliary fan for CPU coolers or AIO radiators: Thanks to the closed-loop motor and higher static pressure, it performs well when mounted on tower heatsinks or thin radiators where resistance is present. Budget-conscious builders who still want quality: be quiet! is a well-respected brand in the PC cooling space; this fan provides excellent durability and reasonable performance without the high price of premium silent fan lines.

Things to Consider

The High Speed variant produces noticeable noise (30.9 dBA) at maximum RPM. If absolute silence is your priority, consider the standard PURE WINGS 3 (1,600 RPM) or Silent Wings 4 (1,200 RPM) instead. While PWM control is included, some older motherboards may lack a 4-pin header or require BIOS configuration to enable PWM mode properly. For radiator use, check that the included screws fit your specific radiator; some AIO radiators use M3 threads that may not match the standard fan screws supplied with this product. Always verify mounting hardware beforehand.
