The Noctua NF-A14x25 G2 might be super-expensive, at 40 dollars, but it offers absolutely top performance at both static pressure and airflow.
I have already evaluated the fan that equips the Noctua NH-D15 G2 cooler (model number Noctua NF-A14x25r G2), which is among the best fans I have ever assessed regarding performance and build quality. The time has come for Noctua to release the square-shaped version of this fan, with model number NF-A14x25 G2.
The Noctua NF-A14x25 G2 achieves a Diamond airflow rating in the Cybenetics Phi scale and a Titanium static pressure rating.

It may hurts eyes, sorry 🙂
Brighter colors – NF-A14x25 G2, 50% PWM
Dimmer – Silent Wings 4 Pro 140, Mid Range, 50% PWM
It looks like the NF-A14x25 G2 is superior to the SW4 Pro as a fan for the case (I’m guided by the graph from Noctua: https://noctua.at/pub/media/wysiwyg/A14_further_reading_1_Highly_optimised_PQ_curve_for_all_applications.png) and for the radiator of the tower cooler, but loses as a fan for the radiator, which generally corresponds to tests on other resources.
Greetings!
Thank you so much for your reviews, everything is simple, technologically advanced and accurate.
I would like to suggest adding a P/Q Graph for 20, 25 and 30 db to compare fans in the “Normalized Noise Tests” category.
It would probably be more visual, and correct, from the point of view of testing performance close to real.
Have you considered this option?
