## Summary description

Phanteks PH-GB6900ASSRX is an aluminum-design water block intended for liquid cooling of compatible graphics cards. It features a full-cover construction for direct GPU cooling, durable metal housing and mounting points for secure installation. Suitable for custom loop systems, it improves heat transfer and helps maintain lower GPU temperatures under load, enhancing stability and longevity.

## Long description

The Phanteks PH-GB6900ASSRX aluminum-design water block is engineered for liquid cooling of compatible graphics cards. It uses a full-cover layout to directly cool the GPU and surrounding components, with an aluminum exterior and reinforced mounting points for a secure fit in custom loop systems. The block improves thermal conductivity compared with air cooling alone, helping to maintain lower GPU temperatures during sustained loads and supporting stable long-term operation.
Advantages
The aluminum housing provides a balance of rigidity and thermal performance while keeping weight low. A full-cover construction ensures direct contact with critical heat-generating parts of the graphics card for efficient heat extraction. Robust mounting points and a metal housing increase mechanical durability and simplify installation in a variety of custom liquid-cooling loops. The design focuses on reliable thermal transfer and predictable performance under extended GPU workloads.
Suitable for
Custom liquid cooling loops for desktop gaming or workstation GPUs
Users upgrading from air coolers to full-cover water cooling
Systems requiring lower GPU temperatures for stability during rendering or prolonged gaming sessions
Environments where a sturdy, metal-bodied block is preferred for durability
Key specifications
Full-cover water block construction for direct GPU and component cooling
Aluminum exterior and structural components
Compatibility with compatible graphics card PCB layouts (check manufacturer compatibility list)
Reinforced mounting points and metal fittings for secure installation
Designed for integration into custom single-loop and multi-loop liquid cooling systems
How to use
Prepare the graphics card by removing the original air cooler and cleaning the GPU and nearby components with isopropyl alcohol. Align the Phanteks aluminum water block over the card so that contact surfaces match the GPU and other cooled components, then install the supplied standoffs and screws according to the manufacturer’s torque recommendations. Connect appropriate fittings and tubing to the water block ports, ensure leak testing of the loop before powering the system, and monitor temperatures after initial use to confirm proper thermal contact and flow.
Usage recommendations
Use compatible thermal interface materials on GPU die and other contact points, follow Phanteks’ compatibility guidance for supported PCB layouts, and perform a pressure/leak test for the entire cooling loop before regular operation. Regularly inspect fittings and tubing for wear and maintain coolant quality to preserve thermal performance and component longevity.
