Overview

A full-cover water block designed for ASUS ROG Strix Radeon RX 6800, 6800 XT, and 6900 XT graphics cards. It cools the GPU, VRAM, and VRM with an optimized split-flow engine and addressable RGB lighting.

Design and Materials

The base is CNC-machined from nickel-plated electrolytic copper. The top and terminals use durable black POM acetal. High-quality EPDM O-rings provide a watertight seal, and brass standoffs come pre-installed for easier mounting.

Cooling Performance

The second-generation Vector engine uses an open split-flow design that reduces hydraulic restriction and eliminates dead spots. Coolant passes directly over the GPU, VRAM, VRM, and inductors to minimize coil whine and maximize thermal transfer.

Lighting and Connectivity

An integrated end-piece holds nine individually addressable D-RGB LEDs and a lit terminal. The 3-pin 5V connector works with ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, and ASRock Polychrome Sync. Two G1/4 ports accept standard fittings.

Included Accessories

The package contains the water block, mounting hardware with screws and washers, two nickel-plated G1/4 plugs, a multi-size Allen key, thermal pads, and a 1-gram syringe of EK-TIM Ectotherm thermal grease.
