"On the heatsink test bench today is NZXT's Havik 120 heatsink, a tower style CPU cooler designed for Intel socket 2011/1366/1155/1156/775 and AMD socket AM2/AM3/AM3+/FM1 processors. The Havik 120 is a pretty typical tower heatsink that ships with two 120mm PWM fans (NZXT's special 'FZ' 13-blade fans) capable of each moving 75CFM per the mfgr's spec. One novel aspect of the Havik 120's design are the edges of its aluminum fins. Each fin has a blunt knife edge which helps ease airflow through the aluminium fin stack by decreasing air flow resistance."
