EK-Quantum Momentum Aorus Z490 Master D-RGB is the new Quantum Line monoblock specifically engineered for the Gigabyte Aorus Z490 Master motherboard. Featuring the latest generation Velocity cooling engine with low restriction and high performance. This monoblock aims to provide a stealthy black look for those who prefer that aesthetic.EK Momentum series monoblocks utilize the 5th generation of the award-winning EK CPU water block cooling engine, further tweaked for performance and optimal coolant flow! This water block directly cools Intel 1200 socket-type CPU, as well as the power regulation (MOSFET) module. Liquid flows directly over all critical areas, providing the enthusiasts with a great solution for high and stable overclocks. Like with every EK monoblock, the EK-Quantum Momentum Aorus Z490 Master features a high flow design and it can be easily used with the system using weaker water pump or lower pump speed settings as well.The purest nickel-plated copper available on the market is used for the cold plate which is precisely machined to a dense micro-fin structure. The nickel-plated brass screw-in standoffs are pre-installed and allow for easy installation. Top of the monoblock features a CNC machined durable POM acetal 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, while the jet plate ensures the best contact surface for the CPU.Unlike other solution on the market, this is a true one-piece, sturdy and reliable liquid cooling product which requires only two connector fittings for proper operation. The enclosed thermal pad is used on voltage regulator modules to improve stability, performance, and prolongs the lifespan of the motherboard. For the CPU, please use the enclosed (electrically non-conductive) thermal grease EK-TIM Ectotherm.Enclosed:- EK-Quantum Momentum Aorus Z490 Master D-RGB Monoblock- Mounting mechanism- Thermal grease EK-TIM Ectotherm- Thermal pads Compatible: Gigabyte Z490 Aorus Master
