The Hyper 412S CPU cooler is designed for optimum heat dissipation at low fan speeds. This is thanks to wider fin gaps & a precise heat pipe layout that directs each of their four heat pipes across CPU "hot zones". These heat pipes are arranged using Cooler Master's patented CDC technology, creating a virtual vapor chamber for maximum cooling potential. The 412S comes equipped with an ultra low speed silent mode fan adapter to virtually erase noise levels.
