The Mine 2 CPU Cooler is based on a twin cooler Layout. Eight copper heatpipes transport heat to two generously dimensioned cooling blocks. By placing the fan in between the 2 heatsink towers, intake as well as exhale airflows are optimized to provide high performance. By default, the Mine 2 will be delivered with a centrally placed, adjustable 140 mm Slip Stream PWM & VR fan. Although the fan supports the PWM feature, the user can manually adjust the PWM bandwidth between 470 to 1,370 rpm and 740 to 1,900 rpm.
