M on Phanteks PH-F120T30: The fan that pushes boundaries For some time now, we know from the results that current, the best 120 mm... 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. 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. To our delightful surprise, the Arctic P12 PWM managed to beat absolutely every other Case Fan that we own.
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. Now I know, 600 rpm, okay, and as a sign that I appreciate that we have such demanding readers, I promise you that sooner or later we will create another mode, which will be twice quieter than the quietest mode that we have now. In addition, we will select fans that will have the highest airflow in the 31 dBA mode and there will be room for further noise reduction. Some fans cannot be slowed down even to 31 dBA mode and of the remaining ones, half of them have a speed of 600 rpm or lower. The NF-A12x25 PWM here allows setting some of the highest speeds mainly because it is PWM controlled, and now I’m not afraid to use the word extremely quiet running of the motor and bearings. This is also visible in the spectrograph, where in the frequency band of these components the noise is extremely low. Noctua deserves all the respect in the world here for going into such details as smoother/quieter PWM waveforms with a slanted left-hand side of the pulses. If you want to control several fans from one unique motherboard header, you can use PWM splitter cables such as the ARCTIC PST Cable rev2 . We however recommend to limit the number of fans per header to 5 as the current may be limited to 1.0 A per header (please refer to your motherboard manual).

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... Overall the P12's performance is excellent. Not only did Arctic's fan outperform a much more expensive rival, but it also managed to beat our 140mm Fans.
There are a lot of droning or downright rumbling fans out there, but none have been as popularized by this sound profile as the Arctic P12. Probably also because this acoustic deficiency is really pronounced here and has pushed the manufacturer to make design changes in newer models that are aimed at suppressing critical tonal peaks. But even so, the base model P12 PWM PST is a remarkable fan and is unbeatable in its price range. Even though the Arctic P12 Line-up does not offer any RGB-Like features or any "nice-looking" design aspects, they do perform excellently. 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. 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. 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.

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). Interesting, I could not notice that the A-RGB and regular version of the P120 has different rotor shapes. The pricing from Arctic makes more sense then.P12 / F12 PWM PST CO => Has a PWM Connection + Daisy Chain Connection + Build for Constant Operation Even though we were perplexed that they did not manage to repeat their results, they performed excellently with 83°C on the CPU. With 62°C on the CPU and 43.5 dbA, the P12 even managed to outrank the Noctua NF-F12 in both metrics, even though the Noctua's are almost double the price. 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.
