Ventilador para caja de PC be quiet! LIGHT WINGS LX 140mm PWM High Speed pack de 3 blanco 14 cm 3 uds.

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

How to use

Install the fan in a compatible 140 mm fan mount inside your PC case, observing airflow direction indicated on the fan frame. Connect the 4-pin PWM cable to a motherboard fan header or compatible controller to enable speed control. Secure the fan with screws provided or standard case fan screws and arrange cables to avoid contact with the blades.

Recommendations

For optimal cooling, configure fan curves in BIOS or motherboard software to adjust speed based on CPU or system temperatures. Maintain clearance from obstructions and clean dust filters and fan blades periodically to preserve airflow and noise performance.
