Earlier this year, Corsair announced its Hydro Pro series of closed-loop liquid coolers. Those heatsinks introduced a stylish new pump-head design kitted out with RGB LED lighting, and they tapped Corsair's exceptional ML-series fans for air-moving power at the radiator end. The first two heatsinks in that series covered two important bases: the H115i Pro for 280-mm radiator mounts, and the behemoth H150i Pro for cases with 360-mm radiator hardpoints.

The bread and butter of the closed-loop liquid-cooler market lies in smaller radiators, though, and 240-mm heat exchangers are the place to be for most builders with mid-towers and mainstream CPU sockets. Today, Corsair is rounding third and headed for home with the 240-mm H100i Pro.
