For a long time, Fractal Design didn’t have fans with impeller geometry that looked “efficient” at first glance. Now come the Momentum fans, which finally do, and the improvement (compared to Aspect models) is clear. This puts the competition on alert, and more importantly, it finally opens up the potential to improve FD’s coolers and cases on the fan level. We’re starting off by testing the most affordable 120 mm model – the Momentum 12.
Results: Airflow through a nylon filter
Why is a value sometimes missing for a fan? There can be several reasons. Most commonly, it’s because the fan couldn’t be regulated to the target noise level. Some fans have higher minimum RPM (or they spin slowly but have an excessively noisy motor), or they are simply slower models that can’t reach higher decibel thresholds. Results are also omitted from graphs if the impeller scrapes against the mesh of a nylon filter. In such cases, we classify the combination as incompatible. And of course, a zero in the graphs naturally appears in situations where we record an actual 0.00. This often occurs at extremely low speeds when obstacles are present or during vibration measurements.
Here are some head‑to‑head comparisons with the (old) NF-A12 (filter, grille). Really interesting results in the low RPM range for the price, aren’t they?
Thank you! 🙂
I’m looking for a decent set of system fans for the top of my NR200. Vibrations are quite a problem there, the top mount is a rather plasticky thing. I’ve noticed that more airflow-focused fans keep the rest of the case cooler – such as the 2.5″ SSD’s mounted in front. Could you tell me what are my best options?
in the case of exhaust fans, I would probably follow the results on radiators… and therefore P14 Pro … if you don’t mind their sound performance… plus they also have an economic charm 😉
… assuming you don’t want them on max…it will probably vibrate there 😛
Thank you. I’ll likely go for P12 Pro. The NR200 cannot mount 140mm fans at the top, or anywhere else in the case for that matter.
yes, as soon as I posted it, I realized that (in 4 minutes 😛 I am already old)… see the following comment 😛
I think that’s a good choice. P12 Pro fans will definitely be beneficial on the exhaust side of system cooling. 🙂
and …my mistake, there only go 120… then NF-A12x25 G2… if you don’t mind the price 😉
Slowed-down P12 Pro fans could also work, but I’m guessing Yamato is looking for a more premium fan (with a higher MTBF rating, for example), since the comment appears under the Momentum 12 review — and those are… not exactly cheap. 🙂
By the way, here you can see other set of the fans but, exactly, in the desired position

Some slower LCP fans might be a good fit. Their operation should generally involve lower vibrations while still maintaining a high airflow even through a grille. The first models that come to mind are the Noctua NF-A12x25 G2 LS (and of course the NF-A12x25 G1 LS as well — especially if you can get them at a better price). But naturally, there can be more options. The key is modern aerodynamic geometry and lower speeds. You can, of course, also slow down fans that don’t have their maximum RPM capped as strictly as Noctua’s LS variants. And the Fractal Design Momentum 12 fans would certainly be suitable too. 🙂
