Our Axial-tech fan design has been optimized for a new, larger heatsink that features more fins and surface area than last gen. The blade count has been increased on all three fans, with 13 on the center fan and 11 on the auxiliary fans. The barrier ring on the side fans has been slimmed down to allow for more lateral intake and to provide better airflow through the cooling array. The center fan’s extra blades and full-height ring provide boosted static pressure to blast air directly onto the heat spreader.
To bolster the specialized roles of the center and auxiliary fans, the rotational direction of the center fan is reversed. This reduces air turbulence inside the cooling array for another boost to overall thermal performance. The fans also shut off completely when card power consumption is low and the GPU temperature falls beneath 50 Celsius, keeping noise levels down when the system is under a light load.
To get heat into the heatsink array efficiently, so that it can be whisked away by the powerful Axial-tech fans. We use a manufacturing process that improves the surface smoothness of the heatspreader at the microscopic level. The extra flatness allows for better contact with the die, helping to enhance thermal transfer.
2.9 Slot Design
The heat spreader draws heat up into heatpipes that carry it through a fin stack that fills a large 2.9-slot footprint. Increasing the heatsink size compared to the last generation provides more thermal headroom to account for the new high-performance chipset.
