As we can see from this design shot, nVidia’s new “TurboFan” design includes an axial fan which pushes air into the cooler, and a radial/centripetal fan that then directs the air through the heatsinks. This is similar to MSI’s RADAX design, as used in MSI’s low-profile GPUs.
Nvidia’s patent claims their new “TurboFan” design will lead to improved cooling and lower noise levels compared to previous stock cooling solutions. Assuming this will be used on Maxwell GPUs, which is likely the case, it could lead to very quiet stock cooling due to the improved cooler and thermal efficiency of Maxwell. I’m personally excited to see how these coolers will perform -- one might even say I’m a … fan of this new design. I expect Maxwell coolers to perform similar to or better than what exists now, considering their stock coolers will likely feature high-performance vapor chambers like Kepler coolers do.
