The CORSAIR NAUTILUS RS Liquid CPU Cooler showcases CORSAIR's engineering and design excellence, offering powerful, quiet cooling with simple connectivity - no controller required, simply connect directly to your motherboard. Its slightly domed cold plate with pre-applied thermal paste provides excellent heat transfer, while the RS120 fans keep temperatures low for maximum CPU performance. Simplify your build with easy, daisy-chain connections and precise cooling control with the 4-pin PWM fan connector. For more advanced control, you can use the optional iCUE controller and adapter cable (sold separately). Supporting a wide range of Intel and AMD CPU sockets, including LGA 1851, the NAUTILUS RS offers broad system compatibility.
