After letting Heavyload grill the CPU, we came to the following results while the Fans were spinning at 100% PWM.

While benchmarking the Fans, we also tried to test if their claims were true. For this, we simply cut the Anti-Vibration Pads of other fans into an acceptable shape and added them to our Benchmark schedule. 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). While Benchmarking, they managed to outperform everything we own under full load and managed to keep a very good position while letting the Fans spin slower. it’s regular PWM, and as mentioned these are quiet enough to fase out at a distance, probably arms length is already enough and it never becomes audible from the actual use distance no matter the speed, it may be some artifact caused by a low PWM setting, maybe slightly flawed PWM controller on the board too as I imagine that may cause troubleP12 / F12 PWM PST CO => Has a PWM Connection + Daisy Chain Connection + Build for Constant Operation dimas on Not every Core i5-13400F is the same: Raptor (B0) vs. Alder (C0) lake sejak kapan ada i5 13500F ? kalau i5 13500 dan 13500T itu baru ada. During the development of the new P12 PWM PST CO, special emphasis was placed on a focused airstream and thus a high static pressure. The fan guarantees extremely efficient cooling, even with increased air resistance. Therefore, the P12 PWM PST CO is particularly suitable for use on heatsinks and radiators. Even though the Arctic P12 Line-up does not offer any RGB-Like features or any "nice-looking" design aspects, they do perform excellently. At a first glance, the Arctic P12 Lineup may be overwhelming, but we will try to make it as clear as possible. Arctic's Lineup of 120mm Case Fans is grouped into 2 big Product Lines, the P12 Series & the F12 Series.

ARCTIC P12 PWM PST - 120 mm Case Fan with PWM Sharing

PDF 429.9KB ACFAN00171A - P12 PWM (White) - RoHS, REACH, PAHs declaration of Compliance - 2022-10-14 Noctua NF-A12x25 beats Arctic P12 when it comes to silent PC cases like Nanoxia Deep Silence 8. The lower frequency of P12 is much harder to stop. With mesh cases, a lot is up to personal preference (apart from CPU cooling where NF-A12x25 shows its teeth). To our delightful surprise, the Arctic P12 PWM managed to beat absolutely every other Case Fan that we own. 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).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. This allowed us to run each of the Fans off one single PWM Header on the mainboard while connecting each of the fans together.
