Cooling block Alphacool Core RX 9070 XT Mercury Transparent Chrome with backplate

The Alphacool Core RX 9070 XT Mercury Transparent Chrome with backplate is a full-cover liquid cooling block engineered for compatible graphics cards. It combines a transparent chrome top with an integrated backplate to provide direct cooling to the GPU area, memory and VRM where applicable. Designed for custom water-cooling loops, the block allows coolant to pass directly over critical components, reducing operating temperatures and enabling quieter system operation under sustained load.

Advantages

This cooling block offers full-cover protection of the GPU area while maintaining a visually distinctive transparent chrome finish. The integrated backplate adds structural support and contributes to heat dissipation on the rear side of the PCB. Flow-optimized internal channels and precision machined contact surfaces ensure even cooling distribution. The unit is compatible with common fittings and standard G1/4" threads used in custom water-cooling setups, simplifying integration into existing loops.

Suitable for

• Custom liquid cooling loops for high-performance gaming or workstation GPUs
• PC builders upgrading from air cooling to direct liquid cooling
• Systems requiring quieter operation and lower GPU temperatures under sustained load
• Enthusiast builds where visual aesthetics and component visibility are important

Key specifications

• Cooling coverage: full-cover design for GPU area including memory and VRM where supported
• Material: transparent chrome top with precision-machined cold plate contact surface
• Mounting: integrated backplate for rear-side support and additional heat transfer
• Thread standard: compatible with standard G1/4" fittings used in custom loops
• Compatibility: designed for use with specific high-performance graphics card models (verify model fitment before purchase)

How to use

Install the cooling block following the manufacturer’s fitting instructions and ensure the graphics card model is supported. Begin by preparing the graphics card: remove the factory cooler and clean the GPU die and component contact areas using appropriate isopropyl alcohol and lint-free cloths. Place thermal interface materials on the GPU die and other contact points as recommended by Alphacool. Align the cold plate and secure the block to the PCB using the provided mounting hardware, making sure screw torque is even and moderate to avoid PCB stress. Connect tubing to the inlet and outlet ports using compatible G1/4" fittings, then perform a leak test with the loop powered off and only the pump running for several minutes before applying power to the full system.

Recommendations

Use high-quality compatible coolant and maintain regular loop maintenance: inspect fittings and tubing for wear, replace coolant per manufacturer intervals, and recheck mounting torque after initial thermal cycles. Verify clearance in your case and confirm compatibility with your GPU model and VRM layout prior to installation to ensure correct contact and optimal thermal performance.
