It is aimed at enthusiasts who plan to swap the stock cooler for a full-cover water block and want a robust copper solution that increases water flow coverage. The single biggest reason to buy is its second generation three-layer structure and 10mm thick copper plate, which are designed to maximize water contact and reduce thermal resistance for the GPU, VRAM and MOS components.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecond generation three-layer structure:\u003c\/strong\u003e Improves water flow distribution over critical areas for more efficient heat transfer across the block.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-precision CNC copper plate:\u003c\/strong\u003e Ensures accurate contact and a large flow coverage area so the GPU core and surrounding components receive effective cooling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10mm thick copper plate:\u003c\/strong\u003e Adds material mass for longevity and allows a single sealing ring design to reduce leakage risk compared with multi-ring thin plates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge area hollowing:\u003c\/strong\u003e Reduces weight while keeping rigidity to protect the PCB from deformation and maintain secure mounting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized positioning columns:\u003c\/strong\u003e Height-optimized columns in the grooves provide precise fit over the GPU core, VRAM and power MOS for reliable thermal contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes fittings:\u003c\/strong\u003e Ships with 2pcs G1\/4 14mm OD rigid tubing compression fittings so builders have essential parts for installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis water block is for PC builders and liquid cooling enthusiasts who own a PowerColor AMD Radeon RX7900XT 20GB Hellhound or one of the closely compatible PCBs listed, and who have experience with GPU block installation.
