So the primary role of the hoop is to stiffen the blade tips, but it also increases the overall fan pressure to some extent as a result. This is because the air streams do not break away from the blade tips as they do with “normal” fans. By these we mean fans from a similar price range, not high-end fans led by the Noctua NF-A12x25, which doesn’t need a framed rotor for a similar and better result. The biggest shortcoming of Arctic’s original P-series fans is the rumbling sound profile. The manufacturer realized this and decided to do something about it. Sensibly, by implementing a hoop to eliminate the critical vibrations that are the source of the annoying acoustic profile. The implementation turned out well, and already the P12 A-RGB shows how much quieter it is compared to the older P12 model. And the list of improvements doesn’t end there.

So these aren’t cheap fans to run. But the expense might be worth it if you’re building a showpiece rig and need high-end RGB lighting to complete the build. Overall, the Corsair QL120 and QL140’s dual-sided RGB and relatively high LED count make them the best-looking RGB fans right now. M on Phanteks PH-F120T30: The fan that pushes boundaries For some time now, we know from the results that current, the best 120 mm... The signal quality of the motherboard/hub should not make a difference in noise, it is determined by the NE-FD1 IC inside the fan. Noctua often has complaints about the PWM signal quality of third party devices and states that it can be misinterpreted at lower speeds. But this is not the case with Noctua fans and it should not affect the noise level anyway, as long as the fan is running stable at the given speed. The misinterpretation of PWM that Noctua mentions is that the fan operation may not correspond to the set PWM duty cycle ( we have discussed this in more detail in this article, where we also discuss the key features of the new Noctua NA-FH1 hub). The P in the name will stand for “Pressure,” which is static pressure. Accordingly, the Arctic P12s do extremely well on radiators in any version – especially when you factor in the low noise. As a case fan and on the air cooler, the Arctic P12 PWM PST A-RGB land in the midfield in terms of performance. In these two areas, the Arctic P12 Max, which seems almost identical in terms of design, pull away noticeably. ConclusionIn the lower price range (which the P12 PWM PST is in) this can still be forgiven, but the more expensive the fan, the worse it gets. The easiest and cheapest way to suppress unwanted vibrations on the blades is by connecting the tips of the blades together to form a kind of hoop. This is also the case with the P12 A-RGB. The advantage of doing this is that cheaper material can still be used and yet the fan does not get into the same “acoustic trouble” as the older Arctic fans. The P12 PWM PST variant is the first to have this hoop. The speed of the fan can be throttled down to standstill via PWM. This allows silent operation in IDLE and at the same time guarantees maximum performance when required. During the development of the new P12 PWM PST CO, special emphasis was placed on a focused airstream and thus a high static pressure. The fan guarantees extremely efficient cooling, even with increased air resistance. Therefore, the P12 PWM PST CO is particularly suitable for use on heatsinks and radiators.

What has remained similar, on the other hand, is the shape of the fan blades. The Arctic P12 Max feel more massive in terms of the motor and fan blades. And that seems to be relevant by the following point in certain areas: Loudness and PerformanceThanks to the 4-pin connector, the RPM can be regulated in a broad spectrum via PWM. In this way, noise is kept at a minimum while maximum cooling performance is guaranteed when needed. The P12 PWM PST is able to switch into silent passive mode when PWM signal is below 5 % due to its new motor. This allows working at your PC in complete silence without any unwanted noise. Additionally, the 120 mm versions of the new P-fans can be easily mounted to existing Freezer 32 and Freezer 33 models. NZXT seems to agree, as the RGB LED ring on the Aer RGB 2 is solely visible on the fan’s intake side. In other words, you’ll only be able to appreciate the Aer RGB 2’s lighting effects when they’re used as exhaust fans. That makes sense, as that’s where high-airflow fans are best used.

Stand out point: If I had to narrow it down to one thing, I would say the fact they gave us a generous amount of cable and the connectors on it will allow you to Daisy Chain. As you mentioned, I also think Arctic’s solution is very cost-efficient way to resolve the unintended vibration of impeller. Everyone knows that the better way is using LCP material, but then the price and difficulties of manufacturing becomes the main problem. But I understand the increase in motor power. I would say the original P12 is quite significantly underpowered, with small headroom. So far, I have also mentioned the be quiet! Silent Wings Pro 4 quite little. Apart from the victory in the high-performance test, they also perform solidly in the other tests. The situation is similar with the ENDORFY Fluctus 120 ARGB. While these RGB fans don’t win any of the tests, they are very high up in each and thus offer a very good average of good performance, low noise, RGB lighting at a mid-range price that isn’t outlandish. The be quiet! Silent Wings Pro 4, ENDORFY Fluctus 120 PWM ARGB, and Arctic P12 are not the overall winners, but deliver very solid results in all tests.The three DeepCool fans are therefore also the budget recommendation for very quiet systems. The FK120, FC120 and CF120 do not give much in this comparison: They offer decent performance even at low speeds.
