This article covers be quiet! Silent Wings 4 120mm 1600RPM プレミアム低ノイズ冷却ファン.

Overview

The be quiet! Silent Wings 4 120mm 1600RPM is a premium case fan from the German high-end cooling specialist be quiet!. Designed for silent operation, it achieves a maximum noise level of just 18.9 dB(A) while delivering 48.7 CFM of airflow and 1.79 mmH2O static pressure. The 3-pin version (model BL092) offers wide compatibility with motherboards that support DC voltage control. This fan is ideal for silent PC builds, radiator cooling, or improving airflow in standard ATX and micro-ATX cases.

Compatibility Guide

The fan adheres to the standard 120mm form factor (120 x 120 x 25 mm) and can be mounted in most PC cases, CPU coolers, and radiators. It includes push-pin and screw-type anti-vibration mounts. The 3-pin connector requires a 3-pin or 4-pin fan header on the motherboard; speed control is achieved via voltage (DC) mode rather than PWM. Users must ensure their motherboard's BIOS can switch to DC mode for proper speed regulation.

Product Info

Released in 2022 as part of the fourth-generation Silent Wings series, this fan represents a high-end silent cooling solution. Key features include a 6-pole fan motor and fluid dynamic bearing (FDB) for quiet, smooth, and long-lasting operation. Typical retail price is around ¥2,500–¥3,000 per fan. The rated power consumption is only 1.4 W, making it extremely energy-efficient. The fan is backed by a 3-year manufacturer warranty.

Best Use Cases

This fan excels in silent PC builds where low noise is paramount – perfect for home theater PCs, office workstations, or recording studios. Its high static pressure also makes it an excellent choice for radiator cooling in liquid-cooled systems. Additionally, it suits budget-conscious builders who want reliable, high-quality fans without paying extra for RGB lighting or PWM features.

Things to Consider

The 3-pin design means no automatic PWM speed control; users must rely on DC voltage regulation, which may not be as convenient. The maximum 1600 RPM speed is modest compared to high-RPM alternatives (e.g., 2500 or 3000 RPM models available in the same series) – if maximum airflow is a priority, a faster variant may be better. Some users report that the push-pin mounts can feel less secure than screws; using the included screws is recommended for a firmer hold. Lastly, there is no LED lighting, so enthusiasts seeking RGB effects should look elsewhere.
