CORSAIR iCUE QL140 RGB 140mm PWM Dual Fan Kit Lighting Node Core

The Corsair CO-9050100-WW is a 140 mm computer case fan designed to provide efficient cooling with low noise. It features a semi-transparent blade design that lets RGB lighting shine through, built-in metal logo plates on both sides of the hub, and corner-mounted rubber dampers to reduce vibration. This fan is compatible with CORSAIR iCUE lighting control when paired with the Lighting Node CORE or other iCUE controllers.

Advantages

Four independent lighting zones and 34 LEDs per fan create vivid RGB effects visible from both sides. The fan delivers effective airflow at up to 1,250 RPM and 50.2 CFM while using PWM for responsive speed control, and its hydraulic bearing improves durability and reduces operational noise. Integrated anti-vibration rubber dampers and a low-noise semi-transparent blade further reduce audible disturbance, and the compact Lighting Node CORE connection minimizes cable clutter when controlling lighting via CORSAIR iCUE.

Suitable for

• Mid-tower or full-tower PC cases that support 140 mm fans
• Systems where synchronized RGB lighting with iCUE is desired
• Quiet workstation or gaming builds needing balanced airflow and low noise

How to use

Mount the fan in a compatible 140 mm fan location using the supplied screws, aligning the airflow direction indicated on the fan frame. Connect the fan’s power and PWM cable to an available fan header on the motherboard or a fan controller; confirm the operating voltage range is supported. For RGB control, connect the fan to the Lighting Node CORE or another compatible iCUE controller and install CORSAIR iCUE software to configure lighting zones and profiles. Use PWM control via the motherboard or controller to let the fan adjust speed according to system temperature.

Recommendations

Install the fan as intake or exhaust according to your case airflow plan, keep fan mounts and surrounding filters clean to maintain airflow, and use PWM-based fan curves in iCUE or the motherboard BIOS to balance cooling performance and noise.
