AIO liquid CPU cooler CORSAIR WAK iCUE LINK TITAN 420 RX 420mm RGB

The CORSAIR WAK iCUE LINK TITAN 420 RX 420mm RGB is an all-in-one liquid CPU cooler engineered for systems that require high thermal performance and customizable lighting. Featuring a 420mm triple-fan radiator, an integrated pump unit with RGB illumination and compatibility with CORSAIR iCUE software, this cooler provides sustained heat dissipation for modern desktop processors. The design balances cooling capacity and aesthetic control for gaming rigs, content-creation workstations, and other high-load builds.

Advantages

The large 420mm radiator offers enhanced surface area for heat transfer, enabling lower CPU temperatures under sustained loads. Integrated RGB lighting on the pump and addressable fan lighting provide coordinated visual customization through CORSAIR iCUE. The sealed all-in-one design reduces maintenance compared with custom loops while delivering performance suitable for high TDP processors. Compatibility with standard 420mm radiator mounts allows flexible installation in mid-tower and full-tower chassis that support extended radiators.

Suitable for

• High-performance gaming PCs that require sustained cooling for overclocked CPUs
• Content-creation workstations running CPU-intensive rendering or encoding tasks
• Professional desktops used for simulation, compilation, or scientific computing
• Enthusiast builds where RGB lighting and synchronized effects are desired

Key specifications

• Radiator size: 420 mm triple-fan configuration for increased thermal surface area
• Cooling type: Closed-loop (all-in-one) liquid cooling system
• Lighting: Addressable RGB on pump and compatible RGB on fans controllable via iCUE
• Compatibility: Designed for modern desktop CPU sockets; check case clearance for 420 mm radiators
• Connections: Power and lighting control through motherboard headers and USB connection for software integration
• Maintenance: Factory-sealed loop requiring minimal user maintenance

How to use

Install the radiator in a compatible chassis location that supports a 420 mm radiator, typically the top or front panel, ensuring sufficient clearance for fans and the hoses. Mount the pump block on the CPU following the included mounting brackets and torque recommendations to ensure even contact with the processor heatspreader. Connect the pump and fan power cables to the appropriate motherboard headers and the USB lead to an internal USB header for iCUE control. Configure fan curves, pump speed, and lighting profiles in CORSAIR iCUE to match thermal and acoustic preferences.

Recommendations

Verify case compatibility and radiator clearance before installation. Route hoses to avoid kinking and ensure fans are oriented for optimal airflow through the radiator. Use the CORSAIR iCUE software to set thermal limits and lighting effects, and monitor temperatures during initial stress testing to confirm proper mounting and thermal performance.
