## Long description

The Phanteks PH-GB6900ASSRX water block is engineered to provide direct liquid cooling for compatible graphics card assemblies. Constructed from a combination of acrylic, aluminum, brass, copper and nickel, the block measures 277 mm wide, 151.3 mm deep and 19 mm high and comes in a black and silver finish. Its materials and dimensions are chosen to ensure efficient heat transfer and reliable integration into custom liquid-cooling loops.
Advantages
This water block combines multiple metals and a clear acrylic top to balance thermal conductivity and visual integration into custom builds. The slim 19 mm profile reduces interference with adjacent components while the broad 277 mm contact area improves cooling coverage. Its mixed-material construction supports efficient heat dissipation and corrosion resistance where applicable, and the neutral black and silver appearance fits a wide range of system aesthetics.
Suitable for
Custom liquid-cooled GPU setups in desktop PCs
High-performance systems requiring improved GPU thermal management
Systems where a low-profile water block design is preferred to save space
Builds that combine visual elements with functional cooling components
Key specifications
Primary materials: acrylic, aluminum, brass, copper, nickel
Dimensions (W × D × H): 277 mm × 151.3 mm × 19 mm
Finish: black and silver
Form factor: full-coverage GPU water block
Compatibility: designed for integration into custom liquid-cooling loops
How to use
Install the water block according to the graphics card and cooling-loop manufacturer instructions. Prepare the system by draining and flushing the loop if replacing an existing block. Place the block onto the GPU’s contact points, secure mounting hardware evenly to the specified torque values, and connect inlet and outlet ports to the loop tubing. After installation, refill the loop with the recommended coolant and perform a leak test at low pump speed before normal operation.
Usage recommendations
Use compatible thermal interface materials and follow manufacturer torque specifications during mounting. Maintain regular coolant changes and system checks to preserve performance and prevent corrosion. Verify clearance around adjacent components when planning the installation to ensure the 19 mm height and 277 mm width fit the intended chassis layout.
