Zalman Reserator 3 MAX Ultimate Liquid CPU Cooler Zalman with its unique technology came up with the world first nanofluids refrigerant applied cooler to maximize the cooling performance. Zalman with its unique technology came up with the world first nanofluids refrigerant applied cooler to maximize the cooling performance. Using nanofluids coolant improves thermal conductivity by mixing nanoparticles with fluids. Nm (nanometer): an SI unit of length, equal to 10?9?m (a billionth of a meter). Slim fin pure cooper dual radial radiator designed for optimized air flow. Four times more powerful cooling efficiency with two copper pipes- Quadro cooling path system. Pure cooper water block & inner micro-fin applied for quick heat transfer. Built-in low noise/ high performance pump inside the water block, minimized the tube connection & helps to speed up the circulation of the coolant for optimized cooling performance. Induction of the airflow inside the case increases cooling efficiency of the motherboard & VRM. Blue LED on the water block & the radiator fan is applied to create the luxurious & powerful image. Extra 120mmfan can be mounted for more powerful performance. (Extra fan available for purchase.) Coolant is already placed inside the confined product, it can be used semi-permanently without replacement or separate maintenance. Features Up to 400 watts cooling performance using dual radiators & nanofluids High performance integrated water pump & nickel-plated radiator Blue LED lighting effect on both the pump & the fan Compatible with most desktop CPU sockets & mid-tower cases
