Great value in a closed loop processor cooler. Hydro Series H80i v2 is an all-in-one liquid CPU cooler with an extra-thick 120mm radiator and dual SP120L 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 H80i v2 makes it easy for you to protect your valuable CPU. The H80i v2 has Corsair Link built in. Just attach the included cable to a USB header on your motherboard and download the free Corsair Link software, and you can monitor CPU and coolant temperatures, adjust fan speeds, and customize the LED lighting directly from your desktop.
