EKWB Unveil Water Blocks for PowerColor RX6900/6800XT Red Devil GPUs

Mike Sanders / 3 years ago

EK Water Blocks (EKWB) has announced its new EK-Quantum Vector Red Devil water block made for the PowerColor Red Devil version of the AMD Radeon RX 6800, RX 6800 XT, and 6900 XT graphics cards. This 2nd-generation EK-Quantum Vector water block implements an Open Split-Flow cooling engine design, which proved to be a superior solution for GPU water blocks. It is characterized by low hydraulic flow restriction, meaning it can be used with weaker water pumps or pumps running on low-speed settings and still achieve top performance. The jet plate and the fin structure geometry have been optimized to provide even flow distribution with minimal losses and optimal performance when used in any given coolant flow orientation, unlike some currently available products on the market.

The base of the block is CNC-machined out of nickel-plated electrolytic copper, while its top is CNC-machined either out of glass-like cast acrylic or durable black POM acetal. The watertight seal is ensured by high-quality EPDM O-rings, while brass standoffs are pre-installed and allow for a safe and easy installation procedure.
