Water block + Heatsink Alphacool Aurora Acryl GPX-A

The Alphacool Aurora Acryl GPX-A is a combined water block and heatsink engineered for Sapphire Nitro+ Radeon RX 6800 XT graphics cards. It integrates a nickel-plated copper cold plate with an acrylic top and extensive addressable RGB illumination to deliver improved thermal management and an aesthetic visual effect. With dimensions of 352 mm x 172 mm x 43 mm and a black/transparent appearance, this unit replaces the stock cooling solution to provide lower operating temperatures for GPU, memory, and VRM components while maintaining a compact profile for many standard PC layouts.

Advantages

This water block increases cooling performance by positioning the cooler closer to heat-generating components through reduced thermal pad thickness and a thinner copper cold plate. Optimized internal water flow enhances heat transfer to the coolant, while nickel plating improves corrosion resistance. Integrated addressable RGB LEDs are embedded along the block to provide uniform lighting across the entire cooler. The design uses copper for its high thermal conductivity and includes flush-mounted stop fittings and clear IN/OUT markings for simpler installation into liquid-cooling loops.

Suitable for

• Custom liquid-cooled Sapphire Nitro+ Radeon RX 6800 XT PC builds
• Systems requiring improved GPU, memory, and VRM thermal control
• Enthusiast rigs where visual aesthetics and aRGB lighting are desired
• High-performance gaming and content-creation workstations using water cooling

How to use

Install the water block by first removing the graphics card’s original cooler according to the manufacturer’s service instructions. Apply the provided or manufacturer-recommended thermal pads and thermal paste with the specified 1 mm pad thickness where required, then position the block over the GPU and secure it using the supplied mounting hardware. Connect the water block to your custom loop using compatible fittings and hoses, matching IN and OUT markings. Power the addressable RGB header to your controller or motherboard header to enable lighting control. Perform a leak test and run the loop at low pump speed until no leaks are detected before regular operation.

Usage recommendations

Use corrosion-inhibited coolant compatible with nickel-plated copper components and avoid mixing dissimilar metals without appropriate inhibitors. Verify mechanical compatibility with your specific Sapphire Nitro+ Radeon RX 6800 XT PCB variant before installation. Follow standard ESD precautions when removing or installing GPU components and ensure the custom loop is properly bled and leak-tested prior to extended use.
