Product information

Description

EK-Quantum Vector Strix RX 6800/6900 is a 2nd generation GPU water block from the EK® Quantum Line, designed specifically for ASUS ROG Strix RX 6800, 6800 XT and 6900 XT graphics cards built on AMD RDNA2 architecture. The block cools the GPU core, VRAM and the VRM by channeling coolant directly over these critical components. Its CNC-machined nickel-plated copper base and glass-like cast acrylic top provide reliable heat transfer and a durable, transparent housing. Pre-installed brass standoffs, EPDM O-rings and included mounting hardware simplify installation.

Advantages

The EK-Quantum Vector Strix RX 6800/6900 offers an Open Split-Flow cooling engine that minimizes hydraulic restriction, allowing effective operation even with lower-speed pumps. Optimized jet plate and fin geometry reduce hydrodynamic instabilities and ensure even coolant distribution across the GPU, VRAM and VRM. The block includes addressable D-RGB lighting with nine individually controllable LEDs and a lit terminal compatible with major motherboard RGB sync standards. High-quality materials—nickel-plated electrolytic copper base, acrylic top and acetal terminals—ensure durability and efficient thermal performance.

Suitable for

  • ASUS ROG Strix Radeon RX 6800, RX 6800 XT and RX 6900 XT graphics cards
  • Custom liquid-cooled PC builds requiring direct GPU, VRAM and VRM cooling
  • Systems using low or medium flow water pumps where low hydraulic restriction is desired

Key specifications

  • Compatibility: ROG Strix RX 6800 / 6800 XT / 6900 XT
  • Materials: Nickel-plated electrolytic copper base, cast acrylic top, acetal terminals
  • Cooling coverage: GPU core, VRAM, VRM and power stages
  • RGB: Addressable D-RGB, 9 individually controllable LEDs, 3-pin connector (+5V alignment required)
  • Sealing: EPDM O-rings; pre-installed brass standoffs
  • Included accessories: mounting mechanism with brass standoffs, screws, nuts, washers, 2x nickel-plated brass G1/4" plugs, EK-Loop multi Allen key (6/8/9 mm), thermal pads, EK-TIM Ectotherm thermal grease (1 g)

How to use

Power off the system and remove the graphics card from your PC. Follow the included mounting guide to replace the stock cooler: remove the factory heatsink, position the EK-Quantum Vector block onto the GPU so the pre-installed brass standoffs align with the card mounting points, and secure it with the supplied screws, nuts and washers. Connect the coolant fittings (G1/4") and ensure the D-RGB 3-pin connector arrow aligns with the +5V marking on your motherboard header. Reinstall the graphics card and perform a leak test before powering the system.

Usage recommendations

Use a compatible retention backplate for improved aesthetics and additional passive cooling for the GPU core and the backside VRM/VRAM areas. Use recommended high-quality coolant and follow standard loop-bleeding and leak-testing procedures; avoid mixing incompatible additives. Ensure the pump provides sufficient flow for your overall loop, though the block is optimized for low hydraulic restriction.
