Zalman Ultra Quiet CPU Cooler with Direct Touch Heat-Pipe Base CNPS10X Performa+ The CNPS10X Performa+ accommodates a broad range of sockets. Intel LGA 2011 / 1155 / 1156 / 1150 / 1366 / 775 / AMD FM2 / FM1 / AM3+ / AM3 / AM2+ / AM2 For optimum case compatibility the heatsink' s height is set to 151mm which ensures compatibility with case width of 180mm or greater. The Slit fin optimized for movement reduces resistance of air flow and covers wider surface area for heat transfer, which allows maximized heat sink function. The heatsink is designed to mount one or two fans according to the users preferences. Heat sink`s bumpy shape has shortened the air movement distance between the fan and the heat pipe, thus minimizing the efficiency level differences between the heat pipes and increasing the heat transferring function via speeding up the hot air flow. DTH technology transfers the CPU`s heat directly to heat pipes, thereby minimizing heat resistance and maximizing cooling performance.
