Water block + Heatsink Alphacool Eisblock Aurora Acryl GPX-A

The Alphacool Eisblock Aurora Acryl GPX-A is a combined water block and heatsink engineered for ASUS TUF Gaming Radeon RX 6900 XT OC and ASUS ROG Strix Radeon RX 6800 XT OC graphics cards. The unit pairs a nickel-plated copper cold plate with an acrylic top and integrated addressable RGB lighting to provide effective GPU, memory and power-stage cooling while preserving a visually consistent appearance inside a desktop system. Its external dimensions are 352 mm × 172 mm × 43 mm and the styling uses black and transparent elements to balance aesthetic integration with other components.

Advantages

The design reduces thermal interface thickness and employs a thinner nickel-plated copper cold plate to improve heat transfer from components to coolant. Optimized internal flow channels increase coolant contact with key components such as the GPU core, memory and voltage regulation circuitry, improving overall thermal performance. Integrated addressable RGB LEDs are embedded along the cooling block to deliver even illumination, while improved nickel plating increases resistance to corrosion and minimizes risk of flaking.

Suitable for

• ASUS TUF Gaming Radeon RX 6900 XT OC and ASUS ROG Strix Radeon RX 6800 XT OC based systems
• Custom water-cooled gaming PCs requiring full-cover GPU cooling
• High-performance builds where reduced GPU temperatures and stable power delivery are desired
• PCs where integrated digital RGB lighting is used for visual coordination

How to use

Install the Eisblock Aurora Acryl GPX-A by first preparing your system according to the graphics card and water-cooling manufacturer instructions: power down, remove the original air cooler and clean thermal residues from the GPU die and surrounding components. Align the water block to the card so that mounting points and contact areas match, apply appropriate thermal pads and thermal compound where required, and fasten the block using the supplied mounting hardware. Connect inlet and outlet fittings to your loop using compatible tubing and secure clamps. Connect the addressable RGB header to a compatible controller or motherboard ARGB connector following polarity and voltage requirements.

Usage recommendations

Use coolant and additives recommended for copper-based loops to prevent corrosion and maintain flow. Verify that the block model matches your exact graphics card revision before installation. Ensure leak testing of the loop at low pump speed for several hours prior to powering the rest of the system. Regularly inspect fittings and coolant condition and replace coolant per the coolant manufacturer's guidance.
