If you need that kind of precision, yes. But I don't think they really need that.

It's par for the course in the premium PC parts industry. It's overkill in a way that does not impact performance at all because gamers will pay for that.

They want them to be really silent. There's more details here: https://www.noctua.at/en/expertise/tech/nf-a12x25-technical-...

Last I checked they weren't really any quieter than their competitors at the same airflow and pressure (which is a little subjective because your curve will never match perfectly). They do have a really low number on their specs because they have a really low max RPM, but that's not really relevant when you can just lower the speed of other fans.

They're still really good fans, but a lot of this is just marketing.

At max power the Noctua NF-A12x25 has 56 CFM and 2.3 mmAq for 31dBA [1]. At 70% the Artic A12 Pro is 56 CFM, 4.3 mmAq, and 31dBA [2]. At 60% the Asus ProArt PF120 is 61 CFM, 2.6 mmAq, and 30 dBA [3].

Note that the ProArt is a bit thicker (25 vs 30 mm) and all these dBA numbers are almost certainly unobstructed airflow. The Noctua is certainly good, but it's literally over 5× the price of the Artic.

It's luxury watch engineering for gamers. You do not need it, but it's kind of charming when anyone competently takes a niche to its extreme, imho.

That said, on my last PC build I ended up buying Pure Wings 3, which are quite competitively silent at similar airflow and much cheaper.

And white. Because I do like silly pretty PCs, as long as they don't have RGB on.

This level of quality is why they have my business. We had a CI setup with rpi boards that needed fans (uart clock tied to cpu clock so heat meant slowing down and the uart dropped characters). I got tired of seeing random test failures on some board and driving up to the office to replace the fan that had failed. And they were loud and annoying. I ended up frustrated and expensing hundreds of dollars of noctua fans. Dead quiet, did a better job, and not even one ever failed on me.
