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.

This is also visible in the spectrograph, where in the frequency band of these components the noise is extremely low.This separation should thus contribute to better user control, especially on mobile devices with smaller displays. Contamination and high temperatures affect this bearing much less than ordinary sleeve or ball bearings.

I guess the difficulty in suppressing the vibrations is why few companies use a similar 5-bladed design.

In any case, it is once again a 120 mm fan that will be taking the top ranks in comparison tests with its performance characteristics. You will find further information in the privacy settings, where you can also change your selection at any time. Modifying” a cooler by replacing the fan with a relatively more efficient model may not always lead to the desired result.Credit is provided by Novuna Personal Finance, a trading style of Mitsubishi HC Capital (UK) PLC, authorised and regulated by the Financial Conduct Authority. Sometimes you will get significantly less improvement than you would expect, other times you may even be worse off. 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. 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.

If the P12 blades were glass, this fan wouldn’t give other fans much of a chance, but again, only until it breaks.Take a look at it, it could be the control… or maybe you own some 3-pin variant of NF-A12x25 (ULN/FLX)?

A leading manufacturer of silent PC coolers and components, it initiated and sustainably influenced the trend towards quiet cooling systems. 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. This means that the airflow loss due to obstacle resistance is smaller with the P12 than with the P120. 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 side effect is that the blade geometry of the BioniX P120 A-RGB does not achieve the same pronounced tonal peaks as the P12. This means that at equal noise levels, you will achieve lower cooling performance, and it doesn’t really matter what fan you use. And these, when they hit the resonant frequencies in an exemplary way, the result is that at the same, let’s say, average noise level, the P12 can indeed be a noisy fan both in the low-frequency (up to 200 Hz) range of sound and between 300–450 Hz. Additionally, this version of the P12 supports PWM Sharing Technology (PST), so the fan speed of the P12 PWM PST can be synchronized with other fans.
