With 62°C on the CPU and 43.5 dbA, the P12 even managed to outrank the Noctua NF-F12 in both metrics, even though the Noctua's are almost double the price. The P12 has larger blades compared to the BioniX P120, although it doesn’t seem like it unless one sees those fans side by side. So with the same size hub, the gaps between the blades are naturally smaller on the P12, so there is less room for airflow leakage and higher static pressure is achieved. This means that the airflow loss due to obstacle resistance is smaller with the P12 than with the P120.

well, it did once the noise became high enough to make all the finetuing Noctua does irrelevant, at 31dB(A) and below there’s no competition, and I hope we’ll see these lower noise targets soon”
CONCLUSION
Once we turned down the PWM Speed to 50%, the P12 placed themselves just behind the Noctua NF-F12 's and Inter-Tech RS-14 (Yes a 140mm set)
ARCTIC P12 PWM - User Manual
One of the differences from the BioniX P120 A-RGB that is also good to notice when judging the results is the smaller offset of the rotor from the frame. The P12 has a half centimeter narrower tunnel, so the rotor is closer to the obstacle, which changes the airflow velocity in addition to the noise. So there is actually a similar effect that the Noctua NA-IS1 frame is supposed to provide. At first, we assumed that this was one of the reasons why these Fans could be so cheap, but upon investigation, it turned out to be a feature.There are a lot of droning or downright rumbling fans out there, but none have been as popularized by this sound profile as the Arctic P12. Probably also because this acoustic deficiency is really pronounced here and has pushed the manufacturer to make design changes in newer models that are aimed at suppressing critical tonal peaks. But even so, the base model P12 PWM PST is a remarkable fan and is unbeatable in its price range. Even though the Arctic P12 Line-up does not offer any RGB-Like features or any "nice-looking" design aspects, they do perform excellently.
ARCTIC P12 Max - High-Performance 120 mm case fan, PWM
To our delightful surprise, the Arctic P12 PWM managed to beat absolutely every other Case Fan that we own. So overall, on the performance side, the Arctic P12's are an excellent choice for anybody that does not want any unnecessary RGB features in their build.Then it’s very strange. We use spectrograms instead of sound recordings for sound analysis precisely because we do not want a dispute to arise at the level of subjective perception of individual frequencies. Everyone sees their intensity in spectrograms in the same way and the results of NF-A12x25 PWM clearly show that there is practically no noise that can be perceived by a person when using PWM control. Or if you can hear some sound in the frequency band we are talking about, you should also hear it with Silent Wings 3.
