An EK-Classic Water Block for the Radeon RX 6800, RX 6800XT, and RX 6900 Graphics Cards

The EK-Classic GPU Water Block RX 6800/6900 D-RGB directly cools the GPU, VRAM, and the VRM (voltage regulation module) as a cooling liquid is channeled right over these critical areas. The water block is in contact with power stages as well as Inductor chokes to maximize cooling and minimize the chances of coil whine. It boasts some new features, already previously introduced in the EK’s Quantum line, such as the optimized flow paths that reduce hydrodynamic instabilities and vortexing (dead spots) inside of them.

The base of the block is CNC-machined out of high-grade 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 already pre-installed and allow for a safe and easy installation procedure.
