EK-Quantum Vector Master RX 6800XT/6900XT - Nickel + Plexi is a 2nd generation Vector GPU water block from the EK® Quantum Line. It is made for AORUS Master 6800XT and 6900XT graphics cards based on the latest AMD® RDNA2™ architecture. For a precise compatibility match of this water block, we recommend you refer to the EK Cooling Configurator.

EK-Quantum Vector Master RX 6800XT/6900XT water block is compatible with AORUS Master Radeon RX 6800XT, and 6900XT graphics cards. The Vector water block 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.

These newly developed water blocks feature optimized flow paths that reduce hydrodynamic instabilities and vortexing (dead spots) inside of them. The EK-Quantum Vector Series water blocks use 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 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.

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. These 2nd generation Vector GPU water blocks also feature acetal terminals. 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.
The aesthetic end-piece is housing the addressable D-RGB LED strip. These water blocks boast a total of 7 individually addressable RGB LEDs, and a LED-lit terminal. They are compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin D-RGB LED connector is to be aligned with the +5V marking on the D-RGB (addressable) header.

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

The HEATKILLER® V eBC backplate is a useful addition for the HEATKILLER® V VGA water blocks. Mounted on the backside of the graphics card, it improves the cooling performance while also granting mechanical stability. This is due to the construction out of massive black anodized aluminum. Even more, it also just looks good.
The backplate cools relevant components on the PCB’s backside, including GPU, RAM, and voltage regulation (VRM). Pre-cut thermal pads are included in the scope of delivery.
Isolating spacers on the backside of the backplate ensure easy installation.
The enclosed mounting material is optimized for usage with HEATKILLER® V water blocks. The backplate can be used with water blocks of other manufacturers. You might need to modify the mounting material, though. This is not part of the delivery scope.
