The hyper 612 ver. 2 includes a PWM controlled fan and provides incredible 11 dB low noise while sustaining excellent cooling performance. Exclusive CDC™ technology, folding fin design, wider fin gaps, and a special 6 heatpipe layout crossing the CPU’s “hot spot,' the Hyper 612 ver. 2 CPU cooler is optimized for superior heat dissipation at low fan speeds, rescuing your machine from a noisy nightmare. Hyper 612 ver. 2 generates only max 20 dB to provide a good operating environment. Without fans, the big fin area will give you dissipation for passive usage. Adopts the innovative patented CDC™ (Continuous Direct Contact) technology - side-by-side heat pipe configurations with no gaps creating a smooth surface for heat conduction. Folding fin design with good air guiding ensuring high efficiency heat dissipation. upported Platforms Intel® LGA 2011 / 1366 / 1156 / 1155 / 1151 / 1150 / 775 socket AMD® AM4* / AM3+ / AM3 / AM2+ / AM2 / FM2+ / FM2 / FM1 socket Heatsink Dimensions (LxWxH) 139 x 102 x 160.4 mm (5.5 x 4 x 6.3 inch) Heatsink Material 6 Continuous Direct contact heatpipes / Aluminum fins Heatsink Weight 732 g / 1.6 lb Heatpipe Dimensions Ø6 mm Fan Dimensions (LxWxH) 120 x 120 x 25 mm (4.7 x 4.7 x 1 inch) Fan Speed 800~1,300 RPM ±10% Fan Air Flow 26.6 - 44.2 CFM (45.2 – 75 m3/h)±10% Fan Air Pressure 0.6 - 1.6 mm H2O ± 10% Fan Life Expectancy 40,000 hrs 40℃ Noise Level 11-20 dBA Bearing Type Rifle bearing Connector 4-Pin Rated Voltage 12 VDC Rated Current 0.09 A Power Consumption 1.08 W Fan Weight 154 g / 0.34 lb Warranty 2 years EAN / UPC Code 4719512047828 / 884102026799 Quick-snap fan bracket design for simple installation.
