Common Applications
The GBN-GV4090WF is a Full Armor full-coverage water block built for the Gigabyte GeForce RTX 4090 Windforce 24G and the Gigabyte Aorus GeForce RTX 4090 Xtreme Waterforce 24G PCBs. The cold plate is nickel-electroplated high-purity copper with a 0.3 mm jet microchannel structure, and the fin area is approximately three times the surface area of the GPU die to maximize heat transfer. The frontplate and backplate are black anodized aluminum armor, fully isolated from the coolant path. A single integrated channel cools the AD102 die, GDDR6X memory, and VRM stages. G1/4 ports on the top and bottom of the block allow serial or parallel plumbing in multi-GPU loops.
