EK-Classic GPU Water Block RX 6800/6900 D-RGB is a high-performance full-cover water block designed for graphics cards based on the latest AMD RDNA2 architecture. This water block fits most reference PCB designs of the Radeon RX 6800, RX 6800XT, and RX 6900 GPUs and is part of the EK Classic Product Line, characterized by a minimalistic and clean design while maintaining class-leading performance. For precise compatibility, we recommend referring to the EK Cooling Configurator.

EK-Classic GPU Water Block RX 6800/6900 D-RGB is compatible with most reference design Radeon RX 6800, RX 6800XT, and 6900 graphics cards. This Classic line water block directly cools the GPU, VRAM, and the VRM (voltage regulation module) as cooling liquid is channeled over these critical areas. The water block is in contact with power stages and inductor chokes to maximize cooling and minimize the chances of coil whine.

The water block's base is CNC-machined out of nickel-plated electrolytic copper, while its top is CNC-machined out of glass-like cast acrylic. The watertight sealing is ensured by high-quality EPDM O-rings, while brass standoffs are pre-installed for a safe and easy installation procedure.

This product is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin LED connector should be aligned with the +5V marking on the D-RGB (A-RGB) header.

EK recommends the purchase of a retention backplate, which improves the overall aesthetics of your graphics cards and provides additional passive cooling for the GPU core and backside of the printed circuit board VRM and VRAM sections.
