Corsair iCUE LINK XG3

This water block is specifically engineered for NVIDIA GeForce RTX 4070 and 4070 Ti series graphics cards. It will not fit other GPU models, so please verify your card's specific layout before purchasing.

Yes, you must have a CORSAIR iCUE LINK System Hub to manage the lighting and monitor the built-in temperature sensor. The iCUE LINK ecosystem uses a proprietary connection system that requires this hub to function.

No, you should only use this block in a loop containing copper or brass components. Mixing metals, particularly aluminum with copper, can lead to galvanic corrosion and permanent damage to your cooling loop.

Yes, the XG3 comes with thermal material pre-applied to the cold plate. This simplifies the installation process and ensures the correct amount of thermal interface material is used for optimal heat transfer.

The XG3 uses a liquid-cooled copper plate to directly dissipate heat from the GPU core and memory, while an integrated fan provides active airflow to the VRMs and circuit board. This dual-action approach ensures that all critical components stay within safe operating temperatures.

To maintain the integrity of the materials and ensure long-term performance, the coolant temperature should not exceed 60°C. We recommend using CORSAIR XL coolant or an equivalent high-quality fluid designed for custom loops.
