What it does

This is a 420mm AIO liquid cooling solution that transfers heat from the CPU via a copper cold plate and liquid loop to a large aluminum radiator, where fans dissipate the heat.

What the key specifications mean

• Cold Plate Material: Copper offers efficient heat conduction away from the CPU surface.
• Radiator Size (420mm): A larger radiator surface allows better heat dissipation, suited to high-heat CPUs.
• Radiator Material: Aluminum construction balances heat dissipation and weight.
• Fan Airflow: The 17.9-94.7 CFM range allows the cooler to adjust between low noise and high cooling performance.
• Fan Static Pressure: Indicates the fans can push air effectively through the radiator fins at higher speeds.
• Speed (300-1700 RPM): Wide RPM range lets the system scale cooling output based on load.
• Noise Level: 10-36 dBA range shows the cooler can run near-silent at idle and louder under heavy load.
• iCUE Software: Allows monitoring and customization of fan/pump behavior and lighting from within Windows.
• Tubing Length (450mm): Determines how far the radiator can be mounted from the CPU block inside the case.
• Tubing Material: Sleeved low-permeation rubber reduces coolant evaporation and adds durability.
• Weight: 2kg total weight should be considered for radiator mounting points and case support.

Practical benefits

• Effective cooling for high-performance or overclocked CPUs
• Quieter operation possible at lower load due to wide RPM/noise range
• Software-based monitoring and control via iCUE

Who it suits

• High-performance desktop builds
• Overclocking enthusiasts
• Users wanting software-controlled cooling and RGB lighting ecosystem integration

Compatibility and installation

• Requires a case with support for a 420mm radiator mounting location
• Requires iCUE software installation for monitoring/control features
• Radiator dimensions: 457mm x 140mm x 27mm
• Tubing length: 450mm, limiting radiator-to-CPU mounting distance
• Total unit weight: 2kg, requiring adequate case radiator mount support
• Cooler block height: 145mm, width: 137mm

Important limitations

• No native PWM support; fan control is digital via Corsair's system
• Specification verification required for full iCUE Link ecosystem/ fan/pump bundle details

Package contents

• Specification verification required.

Buy separately:
