Corsair XG3 GPU Water Block

This water block is specifically designed for NVIDIA GeForce RTX 5080, 5070 Ti, and 5070 GPUs. Please verify your specific card model before purchasing to ensure a proper fit.

Yes, this unit requires a CORSAIR iCUE LINK System Hub to function. The iCUE LINK ecosystem uses a single-cable connection to manage both the lighting and the integrated fan speed through software.

No, you should only use this block in a loop with other copper or brass components. Mixing metals can lead to galvanic corrosion, which will damage your cooling loop over time.

The block comes with thermal paste and thermal pads pre-applied to the contact surfaces. This simplifies installation and ensures you have the correct amount of material for optimal heat transfer right out of the box.

The hybrid design uses a liquid loop to directly cool the GPU core and memory, while an integrated fan provides dedicated airflow to the circuit board and VRM. This dual-action approach helps maintain stability and performance across the entire card, not just the core.

You should use CORSAIR XL coolant or an equivalent high-quality coolant designed for custom PC water cooling loops. Avoid using distilled water or unverified mixtures to prevent biological growth or corrosion.
