Manufacturer description
The be quiet! Light Wings LX 120mm PWM high-speed Triple Pack gives you three matched case fans built for two jobs: pushing air through restrictive radiators and lighting up a showcase build. Each fan's 9 optimized blades produce up to 2.51mm/H2O of static pressure, so they suit water-cooled radiators and air-cooled heatsinks alike. A closed loop motor tracks the actual fan speed and raises it back to the target rpm when a grill, dust filter or radiator slows the blades down. The fan holds the speed you set in your PWM curve, however much resistance it meets. For lighting, 16 LEDs sit inside…

Frequently Asked Questions
Are the be quiet! Light Wings LX 120mm fans good for a radiator?
Yes. Each fan's 9 optimized blades produce up to 2.51mm/H2O of static pressure. be quiet! positions them for both water-cooled radiators and air-cooled heatsinks.
How many fans come in the Light Wings LX Triple Pack?
The pack includes three 120mm PWM high-speed fans. That fills a 360mm radiator, or a 240mm radiator with one fan left over for exhaust.
Can I daisy-chain the Light Wings LX ARGB lighting?
Yes. Each ARGB cable has an input and an output connector. Connect the first fan to your motherboard or an ARGB controller, then chain the other Light Wings LX fans from its output.
What does the closed loop motor do?
It constantly monitors the fan's actual speed and raises it back to the target rpm when a fan grill or radiator slows it down. The fan keeps the speed you set whatever the air resistance.
How is the lighting built into the fan?
16 LEDs sit inside the hub of each impeller and shine outward onto frosted fan blades, so the whole blade area glows. You can choose between multiple colors and lighting modes.
Key Features
- Light Wings LX 120mm PWM high-speed undeniably upgrades all kind of PC cases with its spectacular lighting. Especially show cases with an emphasis on ARGB illumination benefit from this fan. Add a bunch of them to your showcase and let friends and family gaze in awe.
- 16 LEDs are located inside the hub of the impeller of the Light Wings LX 120mm PWM high-speed and shine outwards onto the frosted fan blades. This creates an unmistakable look and enables you to express your creativity.
- With a remarkably high air pressure of up to 2.51mm/H2O, Light Wings LX 120mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The 9 optimized fan blades provide enough air pressure to make this fan work great even in demanding configurations.
- Light Wings LX 120mm PWM high-speed features a closed loop motor. This technology is comparable with the cruise control in cars. When working against resistance, for example a fan grill or radiator, fans spin slower as a result. The closed loop motor technology constantly monitors the current fan speed and increases it to the target rpm, if necessary. As a result, Light Wings LX 120mm PWM high-speed always operates at the desired speed, no matter the air resistance.
- The ARGB connection cable comes with an input and an output connector. The input can be used to connect the fan to your motherboard or to an ARGB controller, but also to daisy-chain it with the output connector of other Light Wings LX fans.
