Product information

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.
