I do not know.
if one can compare the static pressure rating of a 80MM fan vs a 120Mm fan.
I am not sure how the test is performed.
Is a 80mm fan pulling a 80mm column of water up 2.2mm comparable to a 120Mm fan pulling a 120Mm column of water that same distance?
generally high rpmas are going to do well on the static pressure test, and comparing the fans of the same size that have equal results on that, then one can then make assessments as to ampdraw for that staic pressure, and which one is rated for hier airflow(CFM)
Generally noctua seems to perform very well considering the noise made for static pressure, and the nf f12 for its 0.05 amp draw and static pressure is hard to beat.
Ther is another very respected lineup of fans called gentle typhoon from nidec. These are known to perform very well when attached to a computer heatsink.
The latest Noctua 120Mm flagship model's impeller blade shape has remarkable resembelance to the gentle typhoon. Me thinks a patent has expired.
Real world tests in specific usages could easily make the static pressure and cfm ratings, not line up like scared ducks.
The gentle typhoon fan comes in many different rpms, and they used to have a screaming banshee version with 4K+ rpm available, which seemed
to be highly regarded in the overclocker world, but it looks like it is discontinued.
