Single 120 mm RGB case fan

This Corsair LL120 RGB fan is a single 120 mm unit designed for PC builders who want addressable RGB lighting and PWM speed control in a standard case slot. It uses a hydraulic bearing and a 4-pin connector for motherboard-controlled operation.

Airflow and noise limits

The fan spins between 600 and 1500 RPM and delivers 43.25 CFM at a reported 24.8 dBA, giving enough airflow for typical chassis cooling while staying quiet at lower speeds. At maximum RPM the noise rises and the static pressure may not overcome dense radiator fins or restrictive filters.

PWM control and lighting dependencies

The 4-pin PWM connector allows the motherboard to vary speed across the full 600 to 1500 RPM range, but the 16 RGB LEDs split across two light loops require a separate Corsair RGB Lighting Hub and Lighting Node PRO to function. Without those controllers the lighting remains inactive.

Highlights

  • Dual light loops with 16 independent RGB LEDs enable extensive lighting customisation
  • Hydraulic bearing and PWM control from 600 to 1500 RPM balance airflow and noise
  • 25 CFM airflow at 24.8 dBA delivers effective cooling quietly
  • 120 mm x 25 mm frame fits standard case mounts with four included screws
  • Expansion kit design requires RGB hub and Lighting Node PRO for full RGB control

Questions about this item

Will the 120mm frame and 4-pin PWM connector fit my older case and motherboard?

Yes, the fan uses a standard 120mm square frame with 25mm thickness and a 4-pin PWM connector, matching common case mounting holes and motherboard headers.

How can I verify the dual light loops and 16 RGB LEDs are functioning after installation?

Connect the fan to a Corsair RGB Lighting Hub and Lighting Node PRO, then use iCUE software to confirm both light loops illuminate and all 16 LEDs respond to colour changes.

Does the single pack include the Lighting Node PRO and RGB hub needed for RGB control?

No, the box contains only one fan and four mounting screws; the Lighting Node PRO and RGB Lighting Hub are sold separately and are required for RGB functionality.
