Overview

A full-cover water block designed specifically for Palit and Gainward GeForce RTX 5090 graphics cards. It cools the GPU, memory, and VRMs using a symmetrical flow design.

Design and Materials

The block uses a nickel-plated electrolytic copper base paired with a black acrylic top. A screwless exterior and included full-cover backplate create a clean look while protecting the PCB.

Cooling Performance

Symmetrical flow paths distribute coolant evenly across the GPU, memory modules, and voltage regulators. The full-cover design ensures all critical components receive direct liquid cooling.

Lighting and Connectivity

An addressable RGB board connects via a 3-pin 5V digital header. The plug system allows the block to operate with or without the lighting module installed. Six G1/4 ports support multiple inlet and outlet configurations.

Compatibility and Contents

Validated exclusively for Palit GeForce RTX 5090 and Gainward GeForce RTX 5090 graphics cards. The package includes the water block, backplate, ARGB board, and mounting hardware.
