    VARIABLE FAN SPEED FUNCTION

    Adjusts the fan speed and associated noise level

    Pulse Width Modulation (PWM) allows compatible 4-pin controllers, including those built into many motherboards, to intelligently vary the speed and thus the noise level of the fan. With PWM the system can ramp up the cooling when it’s needed, or operate in maximum quiet mode when it’s not.

    LOADING...

    The be quiet! Light Wings 120mm PWM (BL072) is a black, 25mm-thick case fan with ARGB lighting on the front and rear, designed for PC builders who want PWM-controlled airflow, quiet operation rated up to 20.6dB(A), and lighting that can sync with a compatible motherboard.

    Recommended For

    • PC builders adding a 120mm case intake or exhaust fan who want PWM speed control, ARGB lighting, and noise-conscious airflow for a typical case setup.
    • Showcase-PC builders who want visible ARGB lighting from both sides of the fan and plan to connect its lighting to a compatible motherboard or ARGB controller.
    • Noise-conscious builders looking for a case fan they can slow down or speed up with a motherboard PWM fan curve; independent testing measured the standard model at about 20 dBA at maximum speed.
    • Builders replacing a standard case fan in a system with moderate cooling demands who prefer the regular-speed Light Wings over a higher-speed fan designed for more airflow or radiator use.

    Real-World Use Scenarios

    • Adding a 120 mm front intake fan to a compatible case: it can bring fresh air into the case for the CPU and graphics card, while PWM control lets the motherboard adjust fan speed as temperatures change.
    • Building a windowed PC where the fans are visible from inside and outside: front-and-rear ARGB lighting gives the fan an illuminated look from either side, and compatible motherboard lighting controls can coordinate its colors with other components.
    • Replacing a noisy or aging case fan in a standard 120 mm mount: the seven-blade design is intended for case airflow, while PWM lets you use a lower speed for quieter everyday use and raise it when the system needs more cooling.
    • Adding an exhaust fan at the rear or top of a compatible case: it can help move warm air out of the system, complementing existing intake fans and improving the case’s overall airflow path.
    • Choosing fans for a gaming PC with a visible build: the standard-speed Light Wings is intended for case airflow, so it can suit general case-fan positions where lighting and moderate noise are priorities; it is not the High-Speed model aimed at more demanding airflow restrictions.
