Know before you buy
This water block is specifically engineered for the XFX edition of the AMD Radeon 79X0 series. Please verify your specific card's PCB layout against the manufacturer's compatibility list before purchase to ensure a perfect fit.
Yes, the block features a full-cover design that actively cools the GPU core, the memory modules, and the voltage regulator modules (VRMs) to ensure comprehensive thermal management.
The block is designed with wide internal channels to minimize flow resistance. This makes it an excellent choice for custom loops, even those utilizing pumps with lower head pressure.
The package includes pre-cut thermal pads tailored to the specific layout of the supported cards. This simplifies the installation process significantly, as you do not need to measure or cut them yourself.
The block features four G 1/4 inch threads, which is the industry standard for custom water cooling. This allows you to use a wide variety of fittings, including both soft and hard tubing configurations.
The block is constructed from high-purity electrolytic copper for the base, durable stainless steel for the mounting hardware, and a black POM (polyoxymethylene) connection block for long-term reliability.
