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: Static pressure, efficiency depending on orientation
Explanatory note: The orientation of the impeller can affect the resulting static pressure. In these graphs, we examine the ratio between the “pull” and “push” configurations, effectively producing a coefficient. A value greater than 1.00 indicates that the fan produces higher static pressure when pulling. Conversely, a value below 1.00 means it performs better when pushing. In some cases, the ratio is balanced and close to unity.
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. 🙂
