This article covers be quiet! ハイエンドモデル 静音仕様 Be Quiet! SILENT WINGS 4 140mm PWM BL096.
Overview
The be quiet! SILENT WINGS 4 140mm PWM BL096 is a premium case fan designed for users who prioritize low noise without compromising cooling performance. With a maximum speed of 1100 RPM, it features a rifle bearing that keeps noise down to just 13.6 dBA while delivering 51.3 CFM of airflow and 0.92 mmH2O of static pressure. This standard 140x140x25mm fan fits most PC cases and is ideal for silent PC builds. Released in August 2022, it comes with a 5-year warranty and an impressive 300,000-hour lifespan at 25°C. Positioned as a high-end fan in be quiet!'s lineup, the Silent Wings 4 series combines advanced engineering with user-friendly mounting options. Included rubber and hard plastic mounts help isolate vibrations, further reducing noise. Whether used as a case intake/exhaust fan or on a CPU cooler, this model delivers whisper-quiet operation suitable for home theater PCs, office workstations, or high-end gaming rigs.
Compatibility Guide
This fan uses the standard 140mm mounting pattern (105mm pitch) and is compatible with virtually any case that supports 140mm fans. It uses a 4-pin PWM connector for automatic speed control via the motherboard. The 50cm cable length provides ample reach even in full-tower cases. When used on a CPU cooler, ensure there is enough clearance for the 25mm thickness, particularly with tall memory modules or compact coolers.

Best Use Cases
Silent PC Builds: Perfect for users seeking near-silent operation. The low noise level (13.6 dBA) makes it an excellent choice for HTPCs, silent office PCs, or any environment where noise is a concern. Balanced Airflow Systems: With 51.3 CFM and 0.92 mmH2O static pressure, it works well as a case intake fan with dust filters or on a slim radiator (up to 30mm thickness). * Long-term Investments: The 300,000-hour lifespan and 5-year warranty provide peace of mind for users who want to build a system that lasts.
Things to Consider
This fan is limited to 140mm openings; it will not fit 120mm mounts. Its relatively low maximum speed (1100 RPM) may not be sufficient for high-TDP CPUs or heavy overclocking. In such cases, consider using it as an exhaust fan paired with higher-RPM intakes. The PWM header is required to take full advantage of its silent capabilities; without PWM, the fan will run at full speed constantly. Mounting the rubber studs can be tricky – we recommend carefully following the instruction manual.
