This article covers be quiet! 120mm PWM ケースファン SILENT WINGS 3 ハイスピード仕様 3年保証 ブラック BL070.

Overview

The be quiet! SILENT WINGS 3 120mm PWM High-Speed fan (model BL070) is a premium case fan that strikes an excellent balance between airflow and acoustics. With a maximum speed of 2200 RPM, it delivers 73.33 CFM of airflow and 3.37 mmH₂O static pressure while keeping noise to just 28.6 dBA. Its three-phase six-pole motor and fluid-dynamic bearing minimize vibration and wear, backed by a three-year warranty. This fan targets enthusiasts and builders who want high performance without compromising on silence.

Compatibility Guide

This is a standard 120mm × 25mm fan compatible with most PC cases, CPU coolers, and radiators that accept 120mm mounts. It uses a 4-pin PWM connector for automatic speed control via the motherboard. The included rubber anti-vibration mounts help reduce transmitted noise. Ensure your chassis has sufficient clearance (25mm depth is standard) and a free 4-pin fan header. Some very slim cases may not accommodate the 25mm thickness.

Product Info

Released around 2023 and priced at approximately ¥3,800 ( Japan), the SILENT WINGS 3 High-Speed sits in the mid-to-high tier of be quiet!'s fan lineup. It features a three-phase six-pole motor, fluid-dynamic bearing rated for 300,000 hours, and a 3-year warranty. The fan is widely available through online retailers and electronics stores. Its market positioning is for users who demand strong cooling with minimal noise.

Best Use Cases

Silent PC builds: At 28.6 dBA max, this fan is barely audible even under load. The vibration-dampening mounts and rubber frame make it ideal for recording studios or quiet home offices. High-airflow gaming or workstation rigs: High static pressure pushes air through dense radiator fins or mesh panels efficiently, making it suitable for AIO liquid coolers or front intake with dust filters. * Long-term, low-maintenance systems: The fluid-dynamic bearing outlasts standard sleeve bearings, offering a lifespan of over 34 years of continuous use. The three-year warranty provides extra peace of mind. ## Alternatives
Direct competitors include the Noctua NF-A12x25 PWM (around ¥4,500) and the Arctic P12 PWM PST (around ¥1,500). The Noctua offers slightly lower noise and higher static pressure but at a higher price. The Arctic is more affordable but lacks the premium build quality and longer warranty. The SILENT WINGS 3 strikes a sweet spot, delivering performance close to Noctua at a more accessible price point. It also maintains a consistent black aesthetic, ideal for monochrome builds.

Things to Consider

This fan's high-speed variant reaches 2200 RPM, which is louder than the standard SILENT WINGS 3 (1450 RPM). If absolute silence is your top priority, consider the standard version. Also, the fan runs at full speed if your motherboard does not support PWM control. Note that this is a single-pack; if you need multiple fans, the three-pack version (not BL070) may offer better value. Finally, the 25mm thickness might not fit in some slim cases or behind certain chassis panels – measure your available space first.
