be quiet! Silent Wings 4 140mm PWM Gaming PC Case Fan

FEATURES

• The be quiet! Silent Wings 4 140mm PWM High-Speed (BL097) is a premium PC cooling fan designed for users who need strong airflow, high static pressure and quiet operation. Built for demanding gaming PCs, high-performance workstations and custom desktop systems, this 140mm PWM fan combines advanced airflow optimization with reliable components for long-term cooling performance.
• With a maximum speed of 1900 RPM, the Silent Wings 4 140mm PWM High-Speed can deliver airflow of up to 78.4 CFM / 133.2 m³/h and air pressure of up to 2.36 mmH₂O. This makes the fan suitable for a wide range of cooling applications, including PC cases, CPU heatsinks and radiators. Its optimized fan blades are designed to provide high airflow while helping reduce turbulence and unwanted noise.
• The BL097 uses a specially designed fan frame with small tip clearance and funnel-shaped air outlets. This construction helps increase air pressure and directs airflow more effectively toward the cooling components. The result is a fan that can provide strong cooling performance in demanding PC configurations.
• Noise control is an important part of the Silent Wings 4 design. Even at its maximum rated speed, the fan has a noise level of only 29.3 dB(A). The fan also uses a 6-pole motor that helps reduce vibration and provides smooth operation. A high-quality Fluid Dynamic Bearing (FDB) further contributes to reliable and long-lasting performance.
• The 4-pin PWM connector allows the fan speed to be controlled through a compatible motherboard or fan controller. This provides automatic speed adjustment according to system temperature and workload, allowing the fan to deliver additional cooling when required while keeping operation quieter during lighter workloads.
• Installation is flexible thanks to the included rubber and hard-plastic mounting options, push pins and fan screws. The fan can therefore be installed in different PC cases and cooling configurations. A SATA multi-voltage adapter is also included for compatible setups.
• With its 140mm size, high airflow, strong static pressure, PWM speed control, FDB bearing and up to 300,000 hours of rated lifetime at 25°C, the be quiet! Silent Wings 4 140mm PWM High-Speed BL097 is well suited for gaming PCs, enthusiast builds, workstations and other performance-focused desktop systems.
