Pros & Cons

Pros

  • ✓ High 2.51 mm/H2O static pressure suits radiators and restrictive air-cooled builds
  • ✓ 16-LED illuminated hub shines onto frosted blades for even ARGB diffusion
  • ✓ Daisy-chain ARGB cable (input + output) reduces clutter across multiple fans
  • ✓ Closed-loop motor holds target RPM against grill or radiator resistance

Cons

  • ✗ High-speed tuning favors airflow, so it runs louder than quiet-optimized fans at max RPM
  • ✗ Rifle bearing typically lasts less than premium fluid-dynamic bearings
  • ✗ ARGB needs a 3-pin 5V header or controller, unsupported on older motherboards
  • ✗ Sold as a single fan with no bundled ARGB hub or controller included

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.
