be quiet! LIGHT WINGS LX 120mm PWM High Speed 3-Pack White Computer case Fan 12 cm 3 pc(s)

The be quiet! LIGHT WINGS LX 120mm PWM High Speed 3-Pack White includes three high-speed 120 mm case fans designed for effective airflow and noticeable lighting. Each fan reaches up to 2100 RPM, delivers up to 105.1 m³/h airflow and a maximum static pressure of 2.51 mmH2O. Built with rifle bearing technology and a white illuminated impeller, these fans combine reliable operation with a modern appearance suitable for a variety of PC builds.

Advantages

Optimized fan blades and a high maximum rotational speed provide strong airflow and pressure for case ventilation and radiator use. The rifle bearing construction ensures long-term durability and consistent performance. Integrated illumination in the impeller offers visible lighting without compromising the fan’s white aesthetic. PWM control supports automatic speed adjustment across a 5–13.2 V range for flexible system integration.

Suitable for

• Case ventilation in desktop PCs
• Intake or exhaust fan positions
• Cooling radiators in compact or performance-oriented builds
• Systems where white-themed components and lighting are desired
