Water block + Backplate Alphacool 13548 Aluminium Copper 1/4"

The Alphacool Eisblock Aurora water block for Radeon RX 7XXX is a next-generation full-cover cooler and matching backplate designed to improve heat dissipation for high-power graphics cards. The cooler uses an optimized fin structure and a revised jet plate to increase cooling surface and improve water distribution across the fins. Constructed from chrome-plated copper and supplied with Alphacool Subzero thermal paste and Soft Pads, the unit is intended for efficient GPU, memory and VRM cooling.

Advantages

The fin structure was developed in cooperation with AMD board partners and uses 0.4 mm fin thickness with 0.4 mm spacing to balance high cooling surface with good water flow. The revised jet plate evens out water pressure and provides a better angle of inflow for improved heat absorption. Chrome-plated copper construction is more scratch- and acid-resistant than nickel plating, reduces the risk of chipping and provides a more homogeneous reflective surface. Included thermal paste (Subzero, 16 W/mK) and thermal pads (1 mm for VRM/memory at 7 W/mK, 3 mm for the PCB rear at 3 W/mK) support thermal transfer to the block.

Suitable for

• Radeon RX 7000-series graphics cards requiring full-cover water cooling
• Custom liquid-cooled PC builds focused on lower GPU temperatures and quieter operation
• Systems where a chrome-plated copper cooler is preferred for durability and appearance

How to use

Mount the water block onto the GPU following the manufacturer's mounting hardware and step-by-step instructions, ensuring correct alignment with the GPU die, VRM and memory contacts. Apply the supplied Subzero thermal paste to the GPU die as recommended and place the 1 mm Soft Pads on the voltage regulator and memory chips; use the 3 mm pads on the back of the PCB if required. Connect fittings to the 1/4" ports and integrate the block into the loop, then pressure-test and check for leaks before running the system under load.

Usage recommendations

Use compatible G1/4" fittings and ensure the loop is flushed and filled with appropriate coolant. Tighten fittings to the recommended torque and perform a leak test for several hours before normal operation. Avoid abrasive cleaning agents on the chrome-plated surface; use a soft cloth to maintain its appearance.
