The wire is only just laminar flow... I found a random PC fan and assumed a 1mm wire diameter, 2.3m/s airflow, and the reynolds number comes out at 36. That tells me if you were to get a 1000x really powerful fan, then the grille would start giving turbulent flow, and might no longer perform the best.

I even remember, when in mac clones used ultra-high-speed coolers, which now used only in rack devices.
And yes, ultra-high-speed coolers, has much higher speed and make turbulence.
