At the moment, it is pretty difficult to get current-generation graphics cards from both NVIDIA and AMD, but for the lucky few who do, EKWB has you covered for water cooling. EK has just launched the EK-Quantum Vector TUF water blocks specifically made for the ASUS TUF AMD Radeon RX 6800/6900 Series graphics cards.

The 2nd generation EK-Quantum Vector water blocks take advantage of an Open Split-Flow cooling engine design. The main feature of the cooling engine design is the low hydraulic flow restriction which allows the block to function with weaker pumps or at lower settings. The block is CNC-machined out of nickel-plated electrolytic copper while the top plate is either glass-like cast Acrylic or durable black POM acetal. The jet plate and the fin structure geometry have been optimized to offer the best performance with great flow distribution with any coolant flow orientation.
