To summarize our findings, as long as we ignore the fact that the Fans look a bit Outdated or Boring and the short PST Wire, we cannot say anything negative about the P12's in regards to their performance. This allowed us to run each of the Fans off one single PWM Header on the mainboard while connecting each of the fans together.

To our delightful surprise, the Arctic P12 PWM managed to beat absolutely every other Case Fan that we own.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. The P12 has larger blades compared to the BioniX P120, although it doesn’t seem like it unless one sees those fans side by side. So with the same size hub, the gaps between the blades are naturally smaller on the P12, so there is less room for airflow leakage and higher static pressure is achieved. This means that the airflow loss due to obstacle resistance is smaller with the P12 than with the P120. Even though the Arctic P12 Line-up does not offer any RGB-Like features or any "nice-looking" design aspects, they do perform excellently.

The Rest of this review focuses only on the P12 PWM PST fan, but you can expect the exact same results from the P12 PWM (as the only difference is the Daisy Chain). 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. Once we turned down the PWM Speed to 50%, the P12 placed themselves just behind the Noctua NF-F12 's and Inter-Tech RS-14 (Yes a 140mm set) 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). Because the P12's are aimed at the Performance-only market, we will also cease to let their design affect our Review.The P12 Series is pressure optimized, meaning that the Air that the P12 Fan is pushing has a higher pressure, resulting in a better passthrough if the direction it blows is restricted, like by a Radiator or 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. Even though we were perplexed that they did not manage to repeat their results, they performed excellently with 83°C on the CPU.

After letting Heavyload grill the CPU, we came to the following results while the Fans were spinning at 100% PWM. P12 / F12 PWM PST CO => Has a PWM Connection + Daisy Chain Connection + Build for Constant Operation By doing so, we can use the CPU Temperature as an accurate measurement as the CPU temp now only relies on the Air that the Case Fans are pushing into the Case.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).
