EK, the leading computer cooling solutions provider, is launching the new EK-Quantum Vector Nitro+ water block made for the SAPPHIRE NITRO+ version of the AMD Radeon RX 6800XT and RX 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 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.Compatibility:

• Sapphire Nitro+ Radeon RX 6800 XT, 16 GB GDDR6 (11304-02-20G)
• Sapphire Nitro+ Radeon RX 6900 XT (11308-01-20G)

D-RGB Lighting on EK-Quantum Vector Nitro+ RX 6800XT/6900XT Water Blocks
The aesthetic end-piece houses the addressable D-RGB LED strip. These water blocks boast a total of 8 individually addressable RGB LEDs on the Plexi version, while the Acetal has 9 LEDs. They also have a black acetal 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.

Backplate for the EK-Quantum Vector Nitro+ RX 6800XT/6900XT Water Blocks
EK recommends the purchase of an aluminium retention backplate, which improves the overall aesthetics of your graphics cards and also provides additional passive cooling. Cooling is provided for the PCB behind the GPU core, the backside of the VRAM, and the backside of the printed circuit board VRM section on SAPPHIRE NITRO+ 6800 XT and 6900 XT GPUs. It comes in anodized black or nickel-plated variant.

Availability and Pricing
The EK-Quantum Vector Nitro+ RX 6800XT/6900XT GPU water blocks and backplates are made and assembled in Slovenia, Europe, and are available for pre-order through the EK Online Shop and the dedicated reseller network. They are expected to start shipping out in mid-June 2021. In the table below, you can see the manufacturer suggested retail prices (MSRP).
