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… 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 results 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. Perfette per i radiatori o per i case che hanno l'intake coperto da mesh o aperto solo sui lati, grazie all'alta pressione statica, ma vanno bene dappertutto. Le PST possono essere messe a catena quindi usando un singolo header sulla scheda madre.

header (please refer to your motherboard manual). The speed monitoring will be done on the first fan in 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. it’s regular PWM, and as mentioned these are quiet enough to fase out at a distance, probably arms length is already enough and it never becomes audible from the actual use distance no matter the speed, it may be some artifact caused by a low PWM setting, maybe slightly flawed PWM controller on the board too as I imagine that may cause trouble The NZXT Aer RGB 2 fan is one of the best 140 mm RGB case fans on the market, with its 91.19 CFM airflow rating. On the other hand, the static pressure is decent, but nothing to write home about. This is an exhaust fan through and through. 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).

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. 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. Avendo potuto comparare direttamente questa versione "nero/trasparente" con la versione "nero/nero" abbiamo notato che le "nero/trasparente" sono molto più rumorose. ANALOG 4-PIN OUTPUT: The RGB controller has standardized RGB 4-pin connectors, which can be used to connect and control RGB products from ARCTIC and other brands

Arctic P12 PWM PST A-RGB: Hoop? Anti-rumble rescue Arctic P12 PWM PST A-RGB: Hoop? Anti-rumble rescue

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. Now I know, 600 rpm, okay, and as a sign that I appreciate that we have such demanding readers, I promise you that sooner or later we will create another mode, which will be twice quieter than the quietest mode that we have now. In addition, we will select fans that will have the highest airflow in the 31 dBA mode and there will be room for further noise reduction. Some fans cannot be slowed down even to 31 dBA mode and of the remaining ones, half of them have a speed of 600 rpm or lower. The NF-A12x25 PWM here allows setting some of the highest speeds mainly because it is PWM controlled, and now I’m not afraid to use the word extremely quiet running of the motor and bearings. This is also visible in the spectrograph, where in the frequency band of these components the noise is extremely low. Noctua deserves all the respect in the world here for going into such details as smoother/quieter PWM waveforms with a slanted left-hand side of the pulses. INTUITIVE SOFTWARE: The RGB controller is connected to the mainboard and controlled by ARCTIC's RGB software. Without the software, the color spectrum runs sequentially 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.In this test, the temperatures and the noise development are added together. Therefore, it is not surprising that the fans that combine good performance with low noise are at the top. Cooler Master’s Mobius 120 in the regular and RGB versions are at the top together with MSI’s Silent Gale P12. Those who would have expected the Noctua NF-A12x25, which is considered revolutionary and has received a lot of praise, to be at the top will be somewhat disappointed in this case. While these offer good performance as case fans and are quiet, they are definitely beaten by other models in this area. 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. Like the EK and Enermax fans, the Prisma AL-14/PWM connects to your motherboard via a 3-pin ARGB header, saving you from having to spend extra on a controller. Daisy-chaining multiple AL-14/PWM fans together is an option, too. 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. 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. Conclusion

ARCTIC P12 PWM PST ARGB - User Manual

For 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.

I have been trying different ARGB adapters and this is the best price to performance controller to date. No need to use the expensive icue commander or try cooler master adapters which are iffy at best. This Arctic ARGB adapter has lots of modes, clear color with nice fluent effects with clean fading as well as interesting transitions. In the budget range, I had particularly counted on the Arctic fans, with the P12 and P12 Max also delivering upper-class performance at a very low price. The Arctic F12s unfortunately don’t quite make the cut of their 140mm sisters and lose out significantly to the P12 models. The speed of P12 PWM PST 0db ARGB can be adjusted using PWM signal from the motherboard. Please follow this procedure to adjust the settings on your motherboard. 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.
