The twin full-size cooling towers and doubled up fans are only part of the story however, the real coup d'etat is how DeepCool configured its fan speeds. The front 120mm PWM fan operates at 1500-900RPM to drive air through the first 40mm thick aluminum fin stack based on moment to moment CPU thermal requirements while the center 120mm fan operates at a fixed speed of 1300RPM; essentially ensuring a steady volume of airflow is always pulled through the two fin stacks. Consequently, DeepCool's Neptwin sees very little thermal performance fluctuation between its high and low fan speed settings. In short, it's a heatsink ideally sized for Intel LGA2011 platforms and AMD FX-series chips.
For the adventurous out there, the DeepCool Neptwin heatsink even ships with an extra set of springy wire fan clips so a third fan (not supplied) can be tacked onto the rear of the cooler.DeepCool's Neptwin heatsink installs onto Intel socket LGA2011/1366/1155/1156/775 processors and the complete line up of AMD socket AM2/AM3/FM1/FM2 processors.
