Isn’t the Lego Group incredible at this? Their parts are tiny, all different colors, and their tolerances are incredible.

We don't know what Noctua's tolerance is. The clearance in this case has to account for the flexing that will inevitably happen as the fan spins around in an environment than can easily see 50C temperatures. ABS (what Lego uses) begins softening at around 40C, which will increase how much it's deforming at 1500-2500 RPM.
Interestingly enough, I just read about the brown Lego issues earlier today: https://blocksmag.com/brittle-bricks-the-lego-groups-biggest...
Lego is quite impressive, but most of their parts are static and not moving at 500-2000rpm, so they're optimizing for a different problem.
