The centre fan rotates backwards to reduce turbulence and improve air distribution through the heatsink. For the best balance between thermal efficiency and quietness through all details. ASRock's new striped-ring fan provides more side intake and better airflow through the cooling system. Direct airflow more smoothly and quickly to improve cooling efficiency through the V-cut fins and V-shaped vents. The heatpipes are consolidated to maximise contact with each other and with the GPU baseplate for optimised heat dissipation. The premium copper heatsink design maximises the direct contact area with the GPU to effectively improve heat transfer.
