The EK-Pro GPU Zotac RTX 5090 Nickel + Inox is a high performance water block designed for ZOTAC GAMING GeForce RTX 5090 SOLID graphic cards. It efficiently cools GPU, VRAM, and VRM with low flow restriction. Constructed with nickel-plated copper and stainless steel for durability, it features a side_terminal design optimized for workstations. Installation is made easy with pre-installed brass standoffs, and it integrates seamlessly with EK Pro QDC kits and manifolds for high compute-density applications. HIGHLIGHTS ? Occupies just one PCIe slot width ? Efficiently cools GPU, VRAM, and VRM ? Works with weaker water pumps ? Nickel-plated copper base, stainless steel top ? Enhances stability in compact workstations ? Backplate adds rigidity and passive cooling. ?
