The Corsair iCUE LINK RX140 II RGB 140mm PWM fan delivers up to 84.06 CFM of airflow and 2.73 mm-H2O static pressure through a single-cable iCUE LINK ecosystem connection. Engineered with a 140mm x 25mm white frame, this single expansion fan expands your system cooling network while keeping interior cabling exceptionally clean.

High-pressure cooling tailored for radiators and restrictive mesh

Delivering high static pressure is essential when pushing air through dense radiator fins or fine front-panel dust filters. The RX140 II RGB generates up to 2.73 mm-H2O of static pressure alongside an airflow range of 20.16 to 84.06 CFM. Pulse-width modulation (PWM) control allows fine speed adjustments between 350 and 1,700 RPM (±10%), enabling the system to scale fan speeds precisely according to real-time workload requirements.

At the centre of the fan is Corsair's Magnetic Dome bearing technology. This bearing design minimises physical contact to reduce mechanical friction, lowering noise levels to a range between 10 and 31.8 dBA. Lower friction also reduces long-term component wear, ensuring consistent rotation speeds and whisper-quiet performance during light office tasks or intensive gaming sessions.

Streamlined single-cable hookup with integrated thermal monitoring

Traditional PC fans require separate 4-pin PWM and 3-pin RGB headers for every unit, creating significant cable bulk behind motherboard trays. The iCUE LINK interface consolidates power, RGB data, and telemetry into a single unified connector architecture. Fans link sequentially to one another, allowing multiple units to connect back to an iCUE LINK System Hub with minimal cable routing.

Each RX140 II RGB fan includes an integrated thermal sensor. This sensor reports real-time coolant or internal case air temperatures back to Corsair iCUE software, allowing you to create automated fan curves that react instantly to temperature spikes in specific zones of your PC chassis.

Clean white finish with vivid customisable lighting

Designed for clean white-themed builds, the crisp white housing and fan blades reflect light evenly across the entire frame. Integrated into the hub assembly are 8 individually addressable RGB LEDs that produce bright, uniform illumination across the fan blades. Through Corsair iCUE software, lighting effects can be synchronised across all connected iCUE LINK devices or adjusted on a per-LED basis for complete customisation.

Key technical capabilities of this fan include:

• 140mm x 25mm dimensions: Standard form factor fitting most modern dual or triple 140mm fan mounts and radiators.
• 350 to 1,700 RPM PWM control: Expansive tuning range allowing near-silent idling at 10 dBA and max cooling performance at 31.8 dBA.
• Magnetic Dome bearing: Low-friction design engineered for extended operational life and reduced mechanical noise.
• iCUE LINK unified interface: Daisychain connection style that eliminates traditional PWM and RGB cable clutter.
• Built-in thermal sensor: Monitors micro-climate temperatures directly inside your PC chassis for accurate automated cooling curves.
• 5-year warranty: Backed by Corsair's five-year manufacturer warranty for long-term peace of mind.
