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. While the F12 Series is Airflow optimized, it spins way slower (1350 RPM) and produces way less air pressure, but can push a lot of air for such a slow-spinning fan. As we used the P12 PWM in their "PST" Version, we were able to make use of their "Power Sharing Technology". This PST Plug basically adds an additional 3-Pin Output to the cable of Each Fan. Then it’s very strange. We use spectrograms instead of sound recordings for sound analysis precisely because we do not want a dispute to arise at the level of subjective perception of individual frequencies. Everyone sees their intensity in spectrograms in the same way and the results of NF-A12x25 PWM clearly show that there is practically no noise that can be perceived by a person when using PWM control. Or if you can hear some sound in the frequency band we are talking about, you should also hear it with Silent Wings 3.

During the development of the P12 PWM PST, 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 is particularly suitable for use on heatsinks and radiators. A 10 °C lower motor temperature roughly doubles the life span of a fan. The new ARCTIC motor has a four times longer service life through its low coil temperature. Consequently, we have extended the warranty to 10 years. 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). This allowed us to run each of the Fans off one single PWM Header on the mainboard while connecting each of the fans together. 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. 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.Conclusion: The P12 PWM PST is a good, solid built fan. With only five blades I am confident that it will run quieter than those with seven or more blades. Of course, this will depend on the speeds. The fan is perfect for the "no frills" people. I know you can't believe it, but there are some out there that just have not embraced RGB and ARGB and that is OK! However, if you wanted the fan to have a little extra pizzaz, you could always use the Akasa Digital 120mm frame with RGB LED lighting to get the bling. I was not disappointedin it, and I don't think you will be. 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. P12 / F12 PWM PST CO => Has a PWM Connection + Daisy Chain Connection + Build for Constant Operation 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. 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…

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. Even though we were perplexed that they did not manage to repeat their results, they performed excellently with 83°C on the CPU. 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. Did you ever get the chance to look at the Arctic P12/P14 PWM PST CO (=Continuous Operation) version of this fan? I tried to find the information about this and I found that the company resolved the resonance at Rev.2. Also there are a the change at required current(0.08A->0.10A). But I don’t know the difference between Rev.2 and Rev.3.M on Get familiar with measuring the frequency response of sound I've been playing around with spectral analysis app on my phone to estimate RPM of...
Arctic P12 PWM PST Review - STS Tutorial Arctic P12 PWM PST Review - STS Tutorial
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 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.
