The H80 work great with Corsair Link, an ecosystem of hardware and software components designed to give you unprecedented control over your PC. Connect your H80 to the Corsair Link Commander (available separately) and monitor a wide range of parameters, including pump speed, coolant temperature, and fan speed, and customize your own performance profiles. Control at your fingertips. The low-profile integrated pump and cold plate includes push-button control so you can select the fan speed and cooling performance setup that best suits your needs. The cool white LED display lets you know at a glance which profile is being used. The Hydro Series H80: Compact and quiet. The H80 includes a double-thick radiator and two 120mm fans. It can be installed almost anywhere you can install a standard 120mm PC case fan, and includes mounting brackets for all modern CPU sockets. Corsair Hydro Series makes it easy to go liquid. Easy installation, zero maintenance. You no longer need to invest into finicky modular watercooling systems to get serious CPU cooling performance. Each Hydro Series Liquid CPU Cooler is a sealed, closed-loop system that comes pre-filled and never needs refilling. Tubing is constructed from low-evaporation FEP for a long lifespan. Even the thermal compound is pre-applied. You'll be up and running in minutes. The latest cooling technology. The H80 include a low-profile, light-weight cooling unit with a micro-channel copper cold plate and a split-flow manifold. The result of all this attention to fluid dynamics is CPU cooling that's remarkably efficient, with a total noise level that's lower than most stock CPU fans.
