FEATURES

• The be quiet! Pure Wings 3 140mm PWM High-Speed Triple Pack BL138 is a high-performance cooling solution designed for gaming PCs, workstations, performance desktops and demanding cooling configurations. The pack includes three 140mm PWM fans that combine strong airflow, high static pressure and reliable long-term operation, making them suitable for PC cases as well as radiators and heatsinks.
• Each fan operates at speeds of up to 1800 RPM and delivers airflow of up to 72.2 CFM (122.6 m³/h). With air pressure reaching 2.44 mmH₂O, the Pure Wings 3 BL138 is designed to perform effectively in applications where air needs to pass through resistance, including water-cooling radiators, CPU heatsinks, dust filters and restrictive fan grilles.
• One of the key technologies featured in the BL138 is the closed-loop motor. When a fan encounters resistance, its speed can normally decrease. The closed-loop motor continuously monitors the actual fan speed and adjusts it when necessary to maintain the target RPM. This helps provide consistent cooling performance in demanding configurations.
• The fan uses nine optimized blades with a carefully adjusted blade angle to generate high air pressure while maintaining efficient airflow. The optimized frame also helps minimize air leakage, improving the fan's effectiveness when mounted directly against a radiator or heatsink.
• The Pure Wings 3 BL138 uses a durable Rifle bearing and is rated for an operating lifetime of up to 80,000 hours at 25°C. Its 4-pin PWM connector allows compatible motherboards and fan controllers to automatically regulate fan speed according to system temperature and workload. This allows the cooling system to increase airflow when needed and operate more quietly during lighter workloads.
• The black, non-RGB design gives the fans a clean and professional appearance that works well with gaming PCs, workstations and minimalist builds. With three fans included in the package, users can also improve airflow across multiple mounting positions within a compatible PC case.
• With 140mm dimensions, 1800 RPM operation, 72.2 CFM airflow, 2.44 mmH₂O air pressure, closed-loop motor technology, PWM control and long-life Rifle bearing technology, the be quiet! Pure Wings 3 BL138 provides a versatile and dependable cooling solution for high-performance desktop systems.
