The Corsair iCUE LINK RX120 II RGB 120mm PWM Fan Expansion in white delivers up to 3.57 mmH2O of static pressure and 64.72 CFM of airflow through Corsair's single-cable iCUE LINK ecosystem. Designed for liquid cooling radiators and restricted intakes, this 120mm x 25mm fan expands your cooling configuration with minimal cable clutter and precise automated thermal response.
Focused Static Pressure for Radiators and Restricted Intakes
Standard case fans often lose efficiency when blowing air through dense radiator fins or fine dust filters. The iCUE LINK RX120 II RGB features direct static pressure optimization, pushing air through restrictive components with static pressure ranging from 0.21 up to 3.57 mmH2O at full speed. Integrated Corsair AirGuide technology utilizes anti-vortex vanes behind the fan blades to concentrate the exhaust airflow into a direct column, improving surface-area thermal dissipation across radiator cores and front panel mesh.
Magnetic Dome Bearing for Quiet Operation down to Zero RPM
Operating across a PWM duty cycle from 20% to 100%, the fan scales dynamically from 400 up to 2,100 RPM (±10%). At lower speeds, acoustic output drops to 10 dBA for near-silent operation during light desktop tasks. When commanded with a 0% PWM signal via software, the fan supports 0 RPM mode to cease rotation completely under light thermal loads.
Long-term reliability and low acoustic friction are delivered through Corsair's Magnetic Dome bearing design. By reducing mechanical contact within the bearing assembly, it maintains precise blade alignment across the entire operational range while capping maximum noise at 32.8 dBA under peak performance loads.
Smart iCUE LINK Integration with Onboard Thermal Sensing
As part of the iCUE LINK ecosystem, this single expansion unit connects directly to adjacent iCUE LINK devices using unified bridge connectors, eliminating individual fan control and RGB lighting cable runs back to the motherboard. Every RX120 II RGB fan incorporates a built-in thermal probe frame sensor. This enables the iCUE software suite to measure localized air temperatures inside your PC frame, allowing custom fan curves that react directly to temperature shifts in specific hardware zones.
All-White Aesthetic and 5-Year Warranty Protection
Finished in clean white housing with matching light-diffusing blades, this fan matches light-coloured hardware configurations. Eight individual RGB LEDs provide customizable illumination through iCUE, enabling complex lighting patterns synchronized across connected iCUE LINK components. The RX120 II RGB expansion fan is backed by a 5-year manufacturer warranty.
