"At idle the Hydro H80 delivered lower temperatures in both stock and overclocked trim on the Core I7 2600K. When it comes to load temperatures, the H110 is hands down the winner in these tests again both stock and overclocked. In stock trim the Hydro H110 delivers temperatures 30 °C cooler than the reference cooling solution and over 50 °C cooler when overclocked. When compared to the H100, the Hydro Series H110 maintains a 5 °C margin under load, stock and overclocked."
