## Long description

The Alphacool Eisblock Aurora water block and backplate (Acrylic Copper Black, dimensions 285.5 × 144.5 × 34.2 mm) is developed for Radeon RX 7XXX graphics cards to provide improved liquid cooling compared with the previous generation. The cooler combines a revised fin structure, an optimized jet plate and a chrome-plated copper housing to increase heat transfer, improve coolant flow and offer a uniform illuminated appearance when used with digitally addressable RGB LEDs. The package includes a matching backplate and high-performance thermal interface materials for GPUs, memory and VRM.
Advantages
The fin structure, created in collaboration with AMD board partners, uses 0.4 mm thick fins spaced 0.4 mm apart to enlarge cooling surface area while maintaining effective water flow. A modified jet plate evens out water distribution and provides an improved angle of inflow for better heat absorption. The cooler is made entirely of chrome-plated copper, which is harder and more scratch- and acid-resistant than nickel plating and produces a homogeneous shine that improves RGB light diffusion. Included thermal materials—Alphacool Subzero paste (16 W/mK) and soft pads—are specified for high conductivity and reliable contact on GPU, memory and PCB back areas.
Suitable for
Liquid cooling of Radeon RX 7XXX series graphics cards
Custom PC builds requiring a combined water block and backplate (285.5 × 144.5 × 34.2 mm)
Systems using digitally addressable RGB lighting with even light distribution

How to use
Mount the water block onto the Radeon RX 7XXX GPU according to the manufacturer’s mounting instructions and torque specifications. Apply the supplied Alphacool Subzero thermal paste to the GPU die and position the soft thermal pads on the voltage regulator modules and memory chips as indicated in the installation guide. Secure the backplate and connect fittings and tubing to your custom loop, ensuring proper orientation of inflow/outflow for optimal coolant path. Verify that all fasteners are tightened evenly and perform a leak test before powering the system.
Usage recommendations
Use corrosion-inhibited coolant compatible with copper components and verify compatibility of fittings and tubing sizes with the block’s ports. Regularly inspect seals and fittings and replace thermal pads if rebuilding or after extended use to maintain thermal performance.
