> In other words, we would only recommend upgrading to the NF-A12x25 G2 if you seek to lower noise levels as much as possible and if you are willing to sacrifice the maximum performance headroom in worst-case scenarios that the G1 HS-PWM fan provides.

...but it's a plastic panel? I don't understand how this helps with EMC.

Isn't the problem with Noctua (and similar "silent" fans) that they don't offer the same airflow throughput as their noise making bretheren ?
So sometimes its not as easy as "just use Noctua" ?

But I don't think that's an issue for computer cooling unless you're talking about extreme circumstances.

They have a range of fan speeds going up to very high speeds.
Many people doing modifications will substitute a lower airflow fan for even more noise reduction, which might be why you’re thinking they flow less. That’s a function of fan choice, though.
Noctua fans perform very well on a noise-adjusted basis.
