Hi! Thanks for such a detailed review!
I agree, the hero of the review is far from the most productive fan in terms of noise normalization, but its quality is… a separate level
As a person for whom complete noiselessness of assembly is a priority, I cannot accept some models following the NF-A12x25 in the list of the best, simply because, based on personal experience and numerous reviews, after a while very unusual sounds at low rpm (~800-1000 rpm) begin to emanate from them
Therefore, in my personal top, I would give him a solid 2nd place in terms of a combination of factors
The rest is a matter of compatibility of the Phankeks T30 with your build. 😁
Suggestion: it would be cool to add fan testing for near-silent operation, 10 dBa, for example, there are probably a lot of silence maniacs in their builds 🙃
Also, please test the NF-A14 (aka A15 for the NH-D15 cooler)
Thanks!
Happy New Year to your team! 🎄
Happy New Year!
Unfortunately, I cannot do torture testing in noise measurements, for now at least.
This Noctua fan has sky-high quality and its bearing is among the best in today’s market, but since performance is of the highest priority, it needs improvements there.
In the way I test, even 20 dBA is very low, since I measure the fans from 1 meter away. I also have readings for 15 dBA.
