Direct Contact Heatpipes & 57 Stacks of Aluminum Fins 289138mm2 air contact surface area (>16% higher than Blizzard T4 / Hyper T4) of aluminum fins with 4 x Direct Contact heatpipes to provide excellent heat dissipation ‘V’ Shaped Array Aluminum Fins Wide ‘V’ Shaped molding of the Aluminum Fins minimize the contact of the heatsink and the cooling fan. Which increase the airflow and keep the fan away from the hot heatsink, in order to ensure the lifespan of the cooling fan. XtraFlo 120 ARGB LED PWM Fan Wave Shaped and small hub dimension generate extra high airflow. With a wide range PWM fan control from 500 to 1,600 RPM to fine tune and balance fan noise and performance. ‘Top Cover’ Lock the Push & Pull AirFlow To avoid dynamic losses, the ‘Turbo Engine Cover’ & the dual XtroFlo Fan setup provides added pressure to push hot air through the heatsink. Quick-snap Fan Bracket with Anti-vibration Rubber Pads Quickly and easily install, remove, clean or replace the fan / heatsink.
