So I saw that the Fractal Design HP-14 PWM does well but the pricing is close to the other top fans and the packaging is subpar.
However, the airflow oriented HF-14 is not very good even in low restriction testing.

HF-14: 109m3/h at 990RPM (~ 64CFM)
HF-14: 135m3/h at 1200RPM (~79CFM)

At least 3 sources for inferior performance for the HF-14 vs their own HP-14
