Overview

This full-cover water block fits Sapphire Nitro+ Radeon RX 6800XT and 6900XT graphics cards. It cools the GPU, VRAM, and VRM with a nickel-plated copper base and includes addressable RGB lighting.

Design and Materials

The block uses a nickel-plated copper cold plate paired with a subtle acetal top. An aesthetic end-piece houses the addressable LED strip and a lit terminal. A retention backplate is recommended for added passive cooling and visual completion.

Cooling Performance

The open split-flow cooling engine channels liquid directly over the GPU, memory, and voltage regulation modules. Optimized jet plate and fin geometry ensure even flow distribution with minimal hydraulic restriction, allowing use with lower pump speeds.

Lighting and Compatibility

Nine individually addressable RGB LEDs connect via a standard 3-pin 5V D-RGB header. The lighting works with ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, and ASRock Polychrome Sync for system-wide synchronization.
