EK-Quantum Velocity D-RGB AMD is the high-performance premium quality CPU water block for modern AMD processors. It features a design that will enable a vast number of variations and options for enthusiasts and demanding users as well.EK Quantum Velocity series CPU water blocks embed the 5th generation of the award-winning EK CPU water block cooling engine, further tweaked for performance and optimal coolant flow. Low hydraulic flow restriction enables this product to be used in setups using weaker water pumps or lower pump speeds for added silent operation, while still achieving top performance! The water block also comes with addressable RGB illumination. The illuminated D-RGB EK logo connects to a standard 3-pin 5V D-RGB header on the motherboard.The purest copper available on the market is used for the EK-Quantum Velocity cold plate which is precisely machined to a dense micro-fin structure. The contact surface itself is machine polished for better contact with the CPU IHS. This version of the water block features a nickel-plated cold plate and a CNC machined nickel-plated copper top piece. The new cooling engine is characterized by the top-integrated jet nozzle which is combined with a thicker jet plate allowing a more precise bow control. The simplified water block structure offers a more optimized coolant flow and easier maintenance.The block is equipped with a reinforced hold-down bracket, and the enclosed mounting kit includes all the necessary mounting screws, mounting springs, an AMD AM4 backplate, rubber backplate gasket, and a small tube of Thermal Grizzly Hydronaut high-performance thermal paste. The EK-Quantum Velocity CPU water block features a universal mounting mechanism that offers error-preventing, tool-less installation supporting AMD AM4 sockets out of the box. The mounting screws are streamlined and are even smaller than before for an added aesthetical perfection.This product is compatible with all popular D-RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the addressable RGB header.
