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).
These fans feature double ball bearings from Japanese manufacturer NMB. These bearings provide a much longer service life of these fans having a minimum of 500,000 hours. One possible reason to use these bearings is that these fans have high speed. Maintaining these speeds over a much longer time period would need better bearings but it is also surprising that many other manufacturers are providing similar speed range using Fluid Dynamic Bearings. Anyhow, we don’t know if the motor of these fans has a 6-pole, 3-phase design or not. According to ARCTIC using sinus-magnetizing, the new motor only creates about 5 % of the vibration from the commutation of a regular DC motor without a filter. The design of the frame of the P12 is very simple and differs from the others only by the shaped protrusions in the corners where you would expect anti-vibration pads. Arctic doesn’t supply these with this fan, although they would be useful. But again, considering the price, this is something we can’t fault this fan for. In short, a necessary compromise. ARCTIC with their P12 PWM fans has been at an advantage when it comes to noise performance and we have seen that P12 MAX fans at roughly 50% of their speed are now doing what regular P12 PWM fans are doing at their full speed (100% PWM cycle). This has provided P12 MAX a thermal headroom of 3°C (as per our testing) coming from going above 50% PWM cycle. This is one way of doing it. We did not see any benefit of going below 43 B(A) as fans are silent at this range. This tells us that the thermal performance of P12 MAX fans is quite good albeit at a high noise output.Auch in Bezug auf das Design überzeugt der ARCTIC P12 PWM. Sein schlankes Aussehen und die schwarze Farbe fügen sich nahtlos in jedes Gehäuse ein und verleihen ihm einen modernen Look. Die neun Lüfterblätter sind optimal gestaltet, um einen effizienten Luftstrom zu erzeugen. We can already conclude that operating at about 850 rpm is very inconvenient. The fan hums significantly (at 380 Hz), and the airflow is quite low in this setting, disproportionate to the high noise level. Upwards or downwards, however, the high noise level subsides, although resonant frequencies do occur quite often, at different speeds, but you won’t encounter a worse scenario than the one we pointed out above. 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 bought these 2 Arctic P12 fans to replace the ones that came with my Corsair AIO and they blow them out of the water! But I understand the increase in motor power. I would say the original P12 is quite significantly underpowered, with small headroom.
The rotor itself is taller than average for a 15mm profile fan. Support with nylon filters is nevertheless maintained. The height difference between the frame and the rotor is sufficient at the fan intake, even if you use a filter with an unreinforced mesh. But the worse ones, which collapse significantly, can already collide as with all fans. But how come the rotor is above standard height then? There is very little spacing on the other side, between the rotor and the stator slats. It’s very tight there (which you’ll notice even with minimal deflection, typically when cleaning by wiping the blades), but in practice it doesn’t matter. In addition, all the stator slats except the one that runs the cable have an aerodynamic shape, their tips taper towards the blades. There are a few changes in the design department of these fans compared to the regular P12 PWM fans. ARCTIC has still retained the famous 5-blade design but this time around there is a ring attached to the tips of these blades making it one complete assembly. This ring is named Fan Wheel by ARCTIC and it serves the purpose of taking the hit from resistance force from the surface but ensuring that static pressure is maintained without losing airflow.If you are looking for a quiet and powerful fan, Arctic has the perfect solution for you! With the Arctic P12 PWM Max fan , the popular Arctic P12 has been equipped with extra cooling performance and now manages to direct even more cool air onto your components. Thanks to the universal frame design and the high static pressure, the Arctic P12 PWM Max fans can be used in cases, on coolers and on radiators.
They are beast's at getting airflow through mesh filtration! I use them in my 011-Air as a test once other RGB fans costing 3x failed and I'd recommend them in any application. There are many gen 3 nvme drives that outperform the cheap Gen 4 drives. Like my ignorance in buying an sn750se "gen 4"..... It's slower than the sn750 Gen 3 I was going to replace it with!There are two small arrows on one side of the frame. These provide a visual clue to the users in determining the direction of airflow through the fans and the direction in which blades will spin. The fans at 100% of their speed were doing approximately 53 dB(A) at an ambient of 32 dBA. One of the fans was making 76 dB(A) due to bad bearing. We have to mention this since we are testing these fans. Conclusion
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). In this article, we will take a look at these fans and see what the hype all about is. Item: ARCTIC P12 MAX Pricing: MSRP €12.99 at the time of the Review for a single fan 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…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. I wish I had learned that a decade ago. I would still have a 3Dfx voodoo 5 55500 if I'd not been gaming in a storm without an actual surge protector!
