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.
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! 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 fanThe 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 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).
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. 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. 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. Ich habe den ARCTIC P12 PWM Gehäuselüfter für mein PC-Gehäuse gekauft und bin absolut begeistert von seiner Leistung und Zuverlässigkeit. Dieser Lüfter hat meine Erwartungen in jeder Hinsicht übertroffen.Unlike the P12 PWM fans which use Fluid Dynamic Bearings, the P12 MAX fans are using Double-Ball Bearings. We know that double ball bearings can handle the axial and radial loads in both directions which would mean installing these fans vertically or horizontally would not affect the performance in the long run and will provide durability. ARCTIC has employed bearings from Japanese manufacturer NMB. However, there is a catch. Running these fans at high speed would make more noise compared to fluid dynamic or sleeve bearing. These fans have MTTF of >500,000 hours thanks to these bearings. Due to sinus-magnetizing the new motor only creates about 5 % of the vibration from the commutation of a regular DC motor without a filter. Testing 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. Only thing better are the Noctua redux for the price. Don't fall for the RGB hype. I've had 3 Silverstone AIO fans fail with the one below these 2 on it's way out! It'll be replaced by a p12 once it fails! Die PWM-Funktion des Lüfters ist ein weiteres Highlight. Sie ermöglicht eine präzise Steuerung der Lüftergeschwindigkeit, basierend auf der aktuellen Temperatur im Gehäuse. Dadurch bleibt der Lüfter leise, wenn die Temperaturen niedrig sind, und dreht bei Bedarf automatisch schneller, um eine optimale Kühlung zu gewährleisten. Diese Funktion ist besonders praktisch, da sie den Lärmpegel meines Systems reduziert und Energie spart.
Starting out, it’s still worth noting that the Arctic P12 compares with the previously tested BioniX P120 A-RGB, although it has seemingly the same rotor – it doesn’t. And there are more than enough differences, including a shorter tunnel (P12) with less rotor clearance from an obstacle, but let’s start the analysis as usual from the top. Before we take a look at the results, we have pitched the P12 MAX fans against the P12 PWM fans on ARCTIC Liquid Freezer II 360 cooler. Here is a comparison data of these fans: The P12 PWM PST fan (hereafter referred to as the P12, but we’re still talking about the PWM PST variant) has a 5-blade axial rotor, which is typical of Arctic’s current “P” series models. Because of the small number of blades and the intention to achieve high static pressure, each blade must be large. If the blades were smaller, a lot of air would escape through them, which would reduce the airflow the more resistance the fan would have to overcome. Thus there is a considerable cross-sectional area covered by the blades, so that the airflow does not decrease excessively even if the fan is operating on restrictive obstacles. 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.There is no need to be prejudiced against slim fans. If you find a fan with a half profile height fits your small case or on a cooler, feel free to put it there. Figuring out how to get a “standard” one in there after all, even at the expense of a smaller cooler heatsink, may turn out to be a worse option in the end. The connection is made via a 4-pin PWM connector. Arctic uses a high-quality, hydrodynamic plain bearing. This not only guarantees smooth operation, but also ensures that the volume does not increase over time.
