It's different. Blower style are reference design, basically the exact same board nvidia uses for its coolers. Most of the budget boards are, even some of the mid grade gpus. It's only on the higher end you'll run into custom pcbs. You could basically remove the shroud from an nvidia model and the asus turbo and they'll look the same.
Being reference designs, they have reference clocks, reference ram, reference cooling, there's very little, if any difference. With axial designs, vendors can increase cooling ability, but will also increase clocks, so you get the OC models like the Evga SC. The upgrade from that is high end, like the FTW or MSI Gaming X, which have even larger heatsinks and the highest OC clocks. But even so, they'll all see approximately the same temps as the clock speeds and consequent voltage used increase wattage, which increases temps. End result is a few more fps.
You changing your cooling won't affect the fps ability or outputs unless you OC. You'll get the same thing, just a few °C cooler. If you OC to get better performance, your temps will just go back up.
