Product information

Description

The be quiet! LIGHT WINGS LX 140mm PWM High Speed (1800 RPM) is a 140 mm case fan designed to improve airflow in computer systems. It features optimized fan blades, an illuminated impeller for subtle lighting, and a rifle bearing for reliable operation. With a maximum airflow of 127.9 m³/h and PWM control, the fan balances high cooling capacity and controllable speed.

Advantages

The optimized blade design increases airflow while maintaining stable rotation at high RPM. PWM control allows automatic speed adjustment based on system needs. The illuminated impeller provides modest lighting without additional controllers. A rifle bearing ensures durable and quiet operation compared with basic sleeve bearings.

Suitable for

Enhancing airflow in mid-tower and full-tower PC cases
Cooling high-performance components such as CPUs and GPUs when case ventilation is critical
Replacing or upgrading existing 140 mm case fans for better airflow and lighting
