be quiet! LIGHT WINGS LX 140mm PWM BL126 140mm ARGB LED Case Fan

The be quiet! LIGHT WINGS LX 140mm PWM BL126 is a black, single-pack ARGB case fan for PC builders who want to add 140mm case cooling and customizable lighting to a compatible desktop.

Recommended For

• PC builders adding quiet 140mm case ventilation to a compatible case who also want illuminated fan blades; the standard PWM model is rated at 22.9 dB(A) at full speed and includes ARGB lighting.
• Showcase-build owners who want ARGB visible through a case window: the fan’s 16 LEDs illuminate its frosted blades, and its ARGB cable supports daisy-chaining compatible fans.
• Everyday gaming or productivity PC builders seeking a lower-speed 140mm case fan for routine case airflow, rather than a high-speed model; the standard 140mm PWM version tops out at 1,200 RPM.
• Builders replacing or supplementing a single 140mm case fan who want PWM speed control and ARGB without buying a multi-fan pack; this listing is for one fan.

Real-World Use Scenarios

• A builder adding 140mm front intake to a compatible case can use the fan to bring fresh air into the case; the resulting cooling depends on the case layout and the rest of the airflow setup.
• For a home or office PC where fan noise matters, a user can set a motherboard PWM fan curve to keep the fan at a lower speed during everyday tasks; it can ramp up when more airflow is needed.
• When adding a rear or top exhaust fan to a compatible build, the user can help move warm air out of the case; the improvement depends on the existing intake and exhaust arrangement.
• For a PC with a transparent side panel, a user can add this fan for visible ARGB lighting; its illuminated hub and frosted blades diffuse the light across the fan.
• When expanding a case with multiple Light Wings LX fans, the user can daisy-chain their ARGB connections to simplify lighting connections to a motherboard or ARGB controller.
