be quiet! Silent Wings 4 120mm PWM White Cooling Fan

FEATURES

• The be quiet! Silent Wings 4 120mm PWM High-Speed White (BL115) is a premium PC cooling fan designed for users who want powerful airflow, high static pressure and quiet operation in a clean all-white design. With its 120mm form factor and high-speed performance, this fan is suitable for gaming PCs, high-performance desktops, workstations, CPU heatsinks, radiators and demanding PC cooling configurations.
• The Silent Wings 4 BL115 can operate at speeds of up to 2500 RPM, providing airflow of up to 76.7 CFM / 130.3 m³/h and static air pressure of up to 3.96 mmH₂O. Its high air pressure makes it particularly suitable for applications where air must pass through restrictive components such as CPU heatsinks, liquid-cooling radiators and PC case filters.
• be quiet! uses optimized fan blades and a specially designed frame with a small blade-to-frame clearance and funnel-shaped air outlets. This construction is designed to increase air pressure while maintaining controlled airflow and reducing noise-generating turbulence. At maximum speed, the fan has a rated noise level of 31.2 dB(A).
• For smooth and reliable operation, the BL115 uses a 6-pole fan motor combined with a Fluid Dynamic Bearing (FDB). The motor is designed to reduce vibration and power consumption, while the FDB technology contributes to smooth operation and long-term durability. be quiet! rates the fan for a lifespan of up to 300,000 hours at 25°C.
• The fan uses a standard 4-pin PWM connector, allowing compatible motherboards and fan controllers to adjust its speed according to system temperature and workload. The BL115 also supports Zero RPM mode, allowing compatible systems to stop the fan when cooling is not required.
• Installation is flexible because the package includes both rubber and hard-plastic mounting options. Four screws, four push pins and four hard plastic washers are included. The anti-vibration mounting can help reduce vibration transfer, while the hard-plastic mounting is suitable for radiator and heatsink installation.
• The all-white finish makes the Silent Wings 4 BL115 especially suitable for white gaming PC builds and clean custom PC configurations. With high airflow, strong static pressure, PWM control, FDB technology and a long rated lifespan, the be quiet! Silent Wings 4 120mm PWM High-Speed White BL115 provides a combination of performance, durability and low-noise cooling for modern PC systems.
