It also helps keep the shape of the fan constant, stopping the tips of the blades from stretching outwards at high speed and touching the surrounding fin stack.

I never knew that kind of thing also happens.
Do the fans spin high enough for that?
My card's fans only went till 1700 RPM at 76C max.

well, gigabyte GPU's are known for issues like that - it's not super common

It's not exactly common, but for high speed fans (>3000rpm) in tight installations it's not uncommon either. The faster Gentle Typhoon case/radiator fans had outer rings, and that's a 120mm fan - but a very fast, high powered one. That's the reason for Noctua using an expensive liquid crystal polymer in their NF-A12x25 too - it's stiffer and allows the blades to stretch less, meaning they could design the fans with a much smaller gap between the fan frame and blades, improving performance. Most fans avoid this issue by simply having a relatively large gap between the fan blade tips and fan frame/heatsink (often 2mm or thereabouts, compared to .5mm for the NF-A12x25), though that sacrifices a surprising amount of performance as that gap creates turbulence along the fan blade tips, increasing noise and reducing airflow. A ring of course has the downside of dramatically increasing the rotating mass of the fan, necessitating a more powerful motor and more durable bearing, plus a rather fundamental change to how airflow is directed (which can be both good and bad depending on your use case).

The Noctua NF-A12x25 fan was designed with a new type of reinforced plastic just to combat this issue.

The alternative is to just have sloppier tolerances and have a big gap between the fan blade tips and the frame or heatsink fins, but then air leaks through that gap and reduces the efficiency of the fan blades.
