Common Applications
The N-RTX4090H-X-V2 is a full-cover water block engineered for the NVIDIA GeForce RTX 4090 AIC reference PCB, which is shared by partner cards from Inno3D, Galax, and Gainward. The cold plate is nickel-electroplated high-purity copper paired with a stainless steel top panel and POM resin sections, which keeps the assembly ultra-thin. The backplate is black anodized aluminum and is isolated from the coolant path. A high-flow internal geometry covers the AD102 die, GDDR6X memory, and VRM stages in one pass, and G1/4 ports allow multi-block serial loops. This SKU ships without RGB lighting.
