Interesting, I could not notice that the A-RGB and regular version of the P120 has different rotor shapes. The pricing from Arctic makes more sense then. Noctua NF-A12x25 beats Arctic P12 when it comes to silent PC cases like Nanoxia Deep Silence 8. The lower frequency of P12 is much harder to stop. With mesh cases, a lot is up to personal preference (apart from CPU cooling where NF-A12x25 shows its teeth). The “PST” in the name stands for “PWM Sharing Technology,” which means that each fan has a second female 4-pin slot for daisy-chaining multiple fans. It’s a welcome bonus that should help keep your motherboard headers free.
Arctic P12 PWM PST: The most famous rumbling fan Arctic P12 PWM PST: The most famous rumbling fan
EK is well known as a manufacturer of water-cooling components, including radiators. So it’s no surprise that their EK-Vardar EVO 120ER D-RGB fans excel at static pressure. The 3.16 mm-H2O rating of the EVO 120ER makes it the perfect 120 mm RGB fan for radiators and filtered intakes. Die Performance auf dem Radiator ist außergewöhnlich gut, in anderen Bereichen noch immer besser, als man es bei dem Preis erwarten würde. And here’s the P-Fan FAQ, in case you need more information) https://www.arctic.ac/uk_en/p-fan-faq/ Enermax makes up for the single LED ring with a circle of tiny pinholes in the rear housing. It’s not much, but it lets some of the light from the front-mounted LED ring shine through. It’s a nice touch and something more manufacturers could stand to implement in their own designs.The P12 PWM PST A-RGB 0dB has 12 digital A-RGB LEDs in the fan scar. These can be controlled independently of each other and are compatible with the common A-RGB standards of leading motherboard manufacturers. The fan can thus be fully illuminated directly via the A-RGB mainboard connector or via an external controller and synchronised with the illumination of other hardware. At comparable speeds, Arctic’s five-bladed fan rotors deliver higher airflow than most competing solutions, and even at lower noise levels, aside from the aforementioned rumble. It’s just that this sound is characteristic of early P-series fans. The blades are too long, flexible and made of a material with higher thermal expansion. header (please refer to your motherboard manual). The speed monitoring will be done on the first fan in As for the comparison of the paper specifications of the P12 and P12 A-RGB, I really don’t see the technical reason why the static pressure of the P12 at the same speed should be higher by… what, 25%, when at a speed lower by 200 rpm it should be +19%? It makes sense to me the other way round. Of course, a higher static pressure is indirectly caused by the larger hub, if only because it leaves a smaller empty area between the blades. The smaller the fan format, the higher the static pressure per unit of airflow. With the P12 A-RGB, the hoop itself also increases the overall pressure (i.e. static pressure as well) to a certain extent, as I mentioned in the article. 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).
Arctic P12 PWM PST Case Fans : r/buildapc Thoughts on the Arctic P12 PWM PST Case Fans : r/buildapc
Well, the best study would be with P14 rev. 1 vs. rev. 2, if the same motor is used across revisions and the only difference is really in the (non)presence of the hoop. Unfortunately, I cannot agree with this statement even now. The extra details that Noctua has often stand out more with relatively higher speeds. Whether it’s Flow Acceleration Channels, Stepped Inlet Design, a significant narrowing of the gap between the blade tips and the frame or Inner Surface Microstructures. These elements counteract the shortcomings that become stronger with increasing pressure. The fact that the NF-A12x25 gives excellent results at low speeds is largely due to the fact that the operation of the motor and blades does not create any noise, so at this level there are no such pronounced limitations as with other fans, and the NF-A12x25 fits into the same noise level at higher speeds.In addition, Arctic states that the P12 also achieves higher airflow at lower speeds, which is partially true, but not to the extent that the specs suggest. At the same speeds, the P12 A-RGB’s airflow is indeed lower because there’s more hub area for the same overall cross-sectional area. This by approximately 47%. However, in terms of the rotor as a whole, this difference is not that dramatic. Subtracting the internal cross-section (hub), the external cross-section (blades) of the P12 A-RGB is only 4.9% smaller. And it is also important to note that this is in an area where the effect of area on efficiency decreases. The selection of fans is almost confusingly large. And comparisons can often only be found between a few mostly very well-known models. That’s why we decided to do a few big fan tests where fans compete against each other in different areas. This is the 120 mm case fan test, where more than 30 different … (Weiterlesen...) So I must admit that I missed that there are also different revisions of the P12 PWM PST. In this case, ours, tested, will be the rev. 1. – 0.08 A and without the revision specified next to the EAN code. That’s how Artcic usually does it when it’s the first revision… While the SquA punches above its weight when it comes to cooling, it falls a bit short in the looks department. While it shares the single LED ring configuration of NZXT’s Aer RGB 2, the ring on the SquA RGB looks a bit muted in comparison. It’ll add a splash of color to your rig, sure. But compared to some of the other fans on this list, it lags behind in the looks department, at least to our eyes. 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.

At the lower performance end remain the Alseye Xtreme X12, which not only provide the lowest performance, but are also many times louder than the next two fans at the lower performance end. The be quiet! Shadow Wings 2 and the Fractal Design Aspect 12 do not offer high peak performance, but they remain quiet enough on uncontrolled full power that they do not attract negative attention. Observation over all resultsFor being only a 6-euro fan, the precision of production is extremely high. It’s only at the level of really fine detail that you’ll find that the P12 has slightly looser manufacturing tolerances than Arctic fans with a similar rotor. There will be a tiny unevenness here and there on the P12, but it will have virtually no impact on the performance. And at this price range, it’s also a bit unfair to point it out, as similarly priced fans often fare considerably worse.

And one addendum for the discerning reader who will scroll through the comments here and there and might ask the same question as one of the readers of this article in another language. Namely, why the BioniX P120, being more expensive, often achieves a lower airflow than the P12. We discussed a bit in the opening chapter that these fans don’t have the same rotors, but I didn’t want to pay any extra attention to that in the conclusion (these aren’t fans that are in any way competing or that you’ll be deciding between). Thanks 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. 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.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. But I understand the increase in motor power. I would say the original P12 is quite significantly underpowered, with small headroom.
