Common Applications

The A-AS6900STRIX-X is a full-coverage water block engineered for the Asus ROG STRIX LC variants of the Radeon RX 6900 XT and RX 6800 XT Gaming cards, which share the same PCB layout. The cold plate is nickel-electroplated high-purity copper with a PMMA acrylic top, and the backplate is black anodized aluminum kept out of the coolant path. Microchannel routing cools the Navi 21 GPU die, GDDR6 memory, and VRM phases through G1/4 inlet and outlet ports, with top and bottom port pairs supporting series or parallel multi-card loops. A pre-installed 5V 3-pin addressable RGB (RBW) strip provides lighting.
