Powerful Cooling Performance Optimally designed aluminum fins disperse heat away from the CPU via 4 heatpipes while switching noise free high capacity 120mm fan quickly cools the heatsink for stable operation of high performance CPUs. Sharks Fin Blade / Dual Fan Support Optimized for maximum airflow Sharks Fin Blade Fan greatly reduces the turbulence caused by fan rotation thus decreasing the noise and vibration while increasing the airflow. The heatsink is designed to mount one or two fans according to the users preferences. Differentiated Design Direct Touch Heatpipe (DTH) Base Direct Touch Heatpipe (DTH) Base technology transfers the CPUs heat directly to heatpipes thereby minimizing heat resistance and maximizing cooling performance. Compatible with Mid Tower Case(180mm Width) For optimum case compatibility the heatsinks height is set to 152mm which ensures compatibility with case width of 180mm or greater. High Performance Super Thermal Grease ZM-STG2M The high performance super thermal grease ZM-STG2M maximizes heat transfer from the CPU to the base of CNPS10X Optima for intensified cooling performance.
