EK-Quantum Momentum ROG XII Hero is the new Quantum Line monoblock specifically engineered for the ROG Maximus XII Hero an Intel Z490 chipset-based motherboard. Featuring the latest generation Velocity cooling engine with low restriction and high performance.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 ROG Maximus XII Hero features a high flow design and it can be easily used with the system using a 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. The top of the monoblock features a CNC machined black POM acetal 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, 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 ROG Maximus XII Hero Monoblock- Mounting mechanism- Thermal grease EK-TIM Ectotherm- Thermal padsCompatible:ASUS ROG Maximus XII Hero [WI-FI]
