We did a full redesign on the motor, from improved magnets, to changing how the internals are designed to help reduce acoustic noise from the fan. Furthermore we also increased the fan blade count, which creates higher pressure allowing the heatsink and fan to cool better without needing to increase the motor speed and increase noise levels. This will help reduce the temperatures of the card and keep the fan noise down, increasing the lifespan of the card; all of this frees up additional power for overclocking.
EVGA ACX 3.0 coolers feature optimized swept fan blades, double ball bearings and an extreme low power motor, delivering more air flow with less power, unlocking additionjal power for the GPU.
All comparisons above are ACX 1.0, *vs. reference single blower cooling solution, **vs. competitors dual fan cooling solution.
