These fans are using Fluid Dynamic Bearings. ARCTIC has mentioned that they have used a combination of alloy/lubricant developed in Germany to reduce the friction within the bearing. This in turn would generate less heat and improves efficiency. This will increase the service life of the fans. As you can see, these Arctic P12 Max make some noise, but less noise from the environment than there would be in a library, so it’s not annoying at all… we can also tell you that the noise that is heard is that of the air being moved by the fins , there are no vibrations or engine noise.
I do not claim that NF-A12x25 PWM is at 787 rpm (i.e. the speed in our “31 dBA” mode) a noiseless or soundless fan, I am just trying to balance it a bit. At this speed you write about industrial noise or use in noisy technical rooms, which is misleading. I respect that in your idea of quiet operation the NF-A12x25 PWM has an even lower speed. Eight times more intensity than 70 dBA. Maintaining this level for 8 hours causes damage to the eardrums. Each mounting corner has a gray color anti-vibration pad that minimizes the vibrational noise coming from the surface on which the fans are installed.In our measurement, the Arctic P12 Max at maximum speed has managed to move almost 82 CFM of airflow, which is an outrage for a 120mm fan (as you can see in the comparison graph, there is a fan that moves more air but is 140mm). Even at only 1,000 RPM speed, it moves almost 40 CFM of air, which is great, because to this we must add the great static pressure that it is capable of generating… it is a fan that even placing your hand at a distance of 50 cm, Notice the air flow. 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… These new Arctic P12 Max are further proof of the good work done by the Arctic engineering and R&D department, since they have managed to create a fan that, despite being the fastest in its catalog with 3,300 RPM, does not it is excessively noisy and in return offers performance beyond any doubt. In addition, with the simplicity that has always characterized this manufacturer, we do not have RGB or extra flourishes beyond what most users really want and need, something that also helps to offer these P12 Max at a very competitive price: €12.99 per unit.
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. 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. The cable is “ordinary” but solid – flat, with the wires holding together nicely. There are two connectors at the end. One to connect the fan to the motherboard or hub/controllers, and the other to daisy-chain another fan. The cable is 40–45 cm in length.
well, it did once the noise became high enough to make all the finetuing Noctua does irrelevant, at 31dB(A) and below there’s no competition, and I hope we’ll see these lower noise targets soon” Now coming to the main point of thermal performance of these fans, we pitched these fans against ARCTIC’s P12 PWM fans using Liquid Freezer II 360 cooler. Here is a summary: 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 Each fan has a flat cable with a 4-pin PWM connector to power these fans. PWM range is quite good on these fans. As accessories, in this case only a small plastic bag with 4 screws is included to install these fans in a PC case.
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.Finally, it should be noted that the cable does not have any mesh, just the typical plastic coating. Terminates in a 4-pin PWM connector. As we have noted many times, Arctic is a manufacturer that focuses on the performance of its products above the rest of the frills, offering excellent performance at a low noise level, and above all at very competitive prices; All this has made it one of the manufacturers that sells the most refrigeration products in Europe, and for a reason. 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).
