"Apack's new Zerotherm ZF120 heatsink is a refined version of the Zerotherm Nirvana 120, but this is no simple fan switch out - the ZF120 is rebuilt from the heatpipes up. The result is an Intel & AMD compatible heatsink which offers substantially lower temperatures at its lowest and quietest fan speed, and a slight edge at full tilt that may bring it into the Top 10 heatsink list.
