Hydro Series H110i is an all-in-one liquid CPU cooler with a 280mm radiator and dual SP140L PWM fans for cooling that's far superior to stock CPU cooling fans. Liquid cooling simply works better than air cooling, and the self-contained design of the H110i makes it easy for you to protect your valuable CPU. For efficient cooling, bigger is better - it's simple physics. If your PC's case can fit a 280mm radiator, Hydro Series H110i will give you better performance. It's Corsair Link compatible, so you can customize cooling performance, monitor system temperature, and change the color of the RGB LED lighting.
