Actually, more air, more noise. That is always the case. I suspect you meant "the more free area, the less the noise". Velocity plays a bigger factor in mechanically generated noise than volume does, most of the time. Less restriction, more free area, means lower velocities, which means less noise.
You of course can also have harmonics & vibration issues , faster spinning motors usually present more sound & harmonics issues in general, however, that typically isn't an issue with these tiny motors.
I haven't noticed any more noise than the PS4 or the PS4 Slim. In fact, the only people I have ever heard complain about noise from fans on any PS were people that don't regularly clean/dust or vacuum. Last buddy that was complaining about noise from PS3 fan, when I opened it for him, it looked like it had hit a cat on the freeway going 60mph.
