The CORSAIR NAUTILUS RS ARGB Liquid CPU Cooler showcases CORSAIR's excellence in engineering and design, offering efficient, low-noise cooling with straightforward connectivity – no controller required, just plug directly into your motherboard. Its slightly convex cold plate with pre-applied thermal paste ensures superior thermal transfer, while RS120 ARGB fans maintain low temperatures for maximum CPU performance. Eight RGB LEDs on the pump head and each fan light up your system with easy motherboard control. Simplify your build with easy, daisy-chained connections and precise cooling control via a 4-pin PWM fan header. For more advanced control, an optional iCUE controller (sold separately) can be used. Supporting a wide range of Intel and AMD CPU sockets, including LGA 1851, the NAUTILUS RS offers broad system compatibility.
