Water block EK Water Blocks nickel perspex nero grigio

The EK-Quantum Vector² XC3 RTX 3080/90 Active Backplate is a combined water block and active backplate solution designed to cool high-performance GPUs. It integrates a new terminal that replaces the stock terminal of the Vector² water block, linking both parts into a single enclosure with one inlet and one outlet. Constructed from nickel-plated electrolytic copper base and a cast acrylic top, and supplied with a black-anodized aluminum side cover, this unit provides full PCB coverage and a unified appearance while enabling efficient liquid cooling for RTX 3080/3090-class graphics cards.

Advantages

The integrated terminal reduces tubing and clutter by allowing the water block and active backplate to operate as a single unit with one inlet and one outlet. A Direct Link flow solution with a machined brass insert enables both serial and parallel connections from adjacent or opposing sides, increasing installation flexibility with distribution plates or vertical GPU mounts. Hidden magnetic terminal covers improve aesthetics and allow rotating visible branding when the GPU is inverted. CNC-machined components and premium materials ensure precise fit, durability and efficient thermal transfer.

Suitable for

• Liquid cooling setups for NVIDIA RTX 3080 and RTX 3090 graphics cards
• Builds using distribution plates or vertical GPU mounts
• Systems where reduced external tubing and a clean aesthetic are desired

Key specifications

How to use

Install the EK-Quantum Vector² water block onto the GPU following manufacturer mounting instructions, then attach the Vector² Active Backplate using the provided terminal so both pieces form a single sealed unit. Connect the inlet and outlet to your loop using appropriate fittings and tubing; the Direct Link terminal allows routing either in serial or parallel depending on your loop layout. Ensure all fittings are tightened and perform a leak test before powering the system.

Recommendations

Use compatible fittings and tubing rated for your cooling loop and avoid mixing incompatible coolants. Verify compatibility with your specific RTX 3080/3090 PCB layout and mounting points before installation. Perform a thorough leak test and monitor temperatures after first startup.
