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. 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. 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 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.

The low noise area has always been the hobbyhorse of Arctic P12 fans. It seems almost magical how low the volume is in the respective speed ranges. And tending to put the icing on the cake, the Arctic P12 PWM PST A-RGB are even a touch quieter.

By far the weakest fans in this test remain the Alseye X12, apart from that the last places are occupied by the NZXT F120 RGB and the Alphacool Aurora Rise. Case fan at maximum power 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). Did you ever get the chance to look at the Arctic P12/P14 PWM PST CO (=Continuous Operation) version of this 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. And here’s the P-Fan FAQ, in case you need more information) https://www.arctic.ac/uk_en/p-fan-faq/

Arctic P12 PWM PST: The most famous rumbling fan Arctic P12 PWM PST: The most famous rumbling fan

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.I tried to find the information about this and I found that the company resolved the resonance at Rev.2. Also there are a the change at required current(0.08A->0.10A). But I don’t know the difference between Rev.2 and Rev.3. 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… 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...) But I understand the increase in motor power. I would say the original P12 is quite significantly underpowered, with small headroom.

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. 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. 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. 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.

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. 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. 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... I have to admit that I hadn’t heard of the Cooler Master Mobius before the case fan review of the 120mm fans, and I was definitely surprised by them. The same goes for the MSI Silent Gale P12s, which at first glance seem similar in design to the Noctua NF-A12x25s, but perform better as case fans. Due to the lower maximum speed, they fall a bit short in the final test, but they offer excellent performance in a normal volume setting.

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. The system is built as a mid-range test system. The AMD Ryzen 5 3600X is used as the processor (CPU), which is comparable to newer models of the performance class in terms of heat generation. It is cooled by a DeepCool AK400, whose fan is set to a quiet 25% PWM in all tests. The graphics card (GPU) is a GeForce GTX 960, whose fan is set to a constant 35%. Due to the fixed speeds of the processor and graphics card cooler, the case fans are the only variable in the test and enable comparability.Within all testing of all the fans, there was only ever 1°C difference between them. So, the fan is no better or worse at the specific tasks than any other fans we tested. 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.

The register can be accessed through http://www.fca.org.uk Conclusion: The P12 PWM PST is a good, solid built fan. With only five blades I am confident that it will run quieter than those with seven or more blades. Of course, this will depend on the speeds. The fan is perfect for the "no frills" people. I know you can't believe it, but there are some out there that just have not embraced RGB and ARGB and that is OK! However, if you wanted the fan to have a little extra pizzaz, you could always use the Akasa Digital 120mm frame with RGB LED lighting to get the bling. I was not disappointedin it, and I don't think you will be.
