Overview

This all-in-one kit provides a pre-filled, drip-free water cooling loop for RTX 5090 reference design cards. It includes a copper cold plate, 360mm slim radiator, plate kit, three 120mm fans, and thermal paste.

Complete Pre-Filled Loop

The kit arrives pre-filled with coolant and uses drip-free quick-connect couplings. Installation requires no filling, bleeding, or specialized tools. Simply connect the modules, tighten the fittings, and power on the system.

Reference Design Compatibility

The included plate kit is engineered for board partner reference PCBs. It ensures optimal contact between the copper cold plate and GPU components for maximum thermal transfer. A list of validated graphics card models is provided in the specifications.

Radiator and Fan Configuration

The 360mm slim LED radiator fits most cases supporting 360mm mounts; verify case clearance before purchase. The kit includes three 120mm fans configurable at checkout, with mounting screws for both 25mm and 30mm thicknesses.

Modular Expandability

The GPU cooler and radiator function as a matched pair and can be integrated with additional LYNK+ modules. This allows future expansion to cool other components without replacing the existing loop.
