The Hyper 412 PWM CPU Cooler is designed for optimum heat dissipation at low fan speeds. This is thanks to wider fin gaps and 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 412 PWM comes with a high-grade PWM that is controllable via BIOS and OS-based tuning applications.
