FEATURES

• The be quiet! Silent Wings 4 120mm PWM High-Speed (BL094) is a premium high-performance PC case fan designed for users who want powerful cooling without excessive operating noise. Combining optimized fan blades, a high-pressure frame design, a 6-pole fan motor and Fluid Dynamic Bearing technology, the Silent Wings 4 is suitable for gaming PCs, performance workstations, custom-built desktops, radiators, CPU heatsinks and demanding cooling applications.
• With a maximum speed of 2500 RPM, the Silent Wings 4 120mm PWM High-Speed delivers airflow of up to 76.7 CFM / 130.3 m³/h and air pressure of up to 3.96 mmH₂O. This high static pressure makes the fan particularly useful for applications where air needs to pass through restrictive components such as radiator fins, CPU heatsinks and dense PC case filters.
• The fan features specially optimized blades and a reduced clearance between the blades and frame. Its funnel-shaped frame outlet is designed to increase air pressure and help provide focused airflow. These features allow the BL094 to combine high cooling performance with controlled acoustics, with a maximum rated noise level of only 31.2 dB(A).
• The 4-pin PWM connector provides precise fan-speed control through a compatible motherboard or fan controller. PWM control allows the system to automatically adjust fan speed according to temperature and workload, helping provide additional cooling when the PC is under heavy load while reducing unnecessary fan noise during lighter workloads.
• For reliability, the Silent Wings 4 uses a Fluid Dynamic Bearing (FDB) and a 6-pole fan motor. According to be quiet!, the fan has a rated lifespan of up to 300,000 hours at 25°C, making it suitable for long-term PC cooling applications.
• Installation is also flexible. The BL094 includes both rubber and hard-plastic mounting options, allowing it to be installed in different configurations. It supports both push-pin and screw mounting, making it suitable for use as a case fan, radiator fan or heatsink fan.
• With its all-black design, 120mm form factor, high airflow, strong static pressure, PWM control and long operating lifespan, the be quiet! Silent Wings 4 120mm PWM High-Speed BL094 is a strong cooling option for gaming PCs, high-performance desktops and custom PC builds where cooling performance and quiet operation are important.
