Also, this version of the P12 supports PWM sharing technology (PST) so that the fan speed of the P12 PWM PST can be synchronized with other fans. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . In this way, less heat develops, less bearing noise is generated and the service life of the fan is extended.

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. I recently bought the value pack of P12 PWM PST and I couldn’t find any rotational speeds that makes the resonant noise. But on a thicker radiator in one of the model situations, the Arctic P12 ranked as high as just behind the Noctua NF-A12x25 PWM. 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. 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.These can be controlled independently of each other and are compatible with the common A-RGB standards of leading motherboard manufacturers. We don’t share your credit card details with third-party sellers, and we don’t sell your information to others. The P12 PWM PST is able to switch into silent passive mode when PWM signal is below 5 % due to its new motor. The premium quality of the dual ball bearing allows 24/7 continuous operation without compromising performance.

I don’t remember other peaking frequencies, but 1 kHz and the following harmonic peaks each full kHz are a case of USB interface noise. During the development of the new P12 PWM PST, special emphasis was placed on a focused airstream and thus a high static pressure.PayPal Credit and PayPal Pay in 3 are trading names of PayPal UK Ltd, Whittaker House, Whittaker Avenue, Richmond-Upon-Thames, Surrey, United Kingdom, TW9 1EH. Numerous improvements, such as updated engine technology and a newly developed fan design, have noticeably increased the performance of P-fans.

I guess the difficulty in suppressing the vibrations is why few companies use a similar 5-bladed design. Dust and high temperature are affecting this bearing a lot less than generic sleeve or one ball bearings and thus make it the perfect choice when reliability is essential. The leading edges of the P12 are significantly curved so that the air streams have a cylindrical trajectory and more effectively avoid contact with the frame.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. In this way, noise is kept at a minimum while maximum cooling performance is guaranteed when needed. 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.

The operating noise of the newly developed ARCTIC motor is barely perceptible even at the lowest speed. Normally I would find the silver screws unattractive, but, this particular fan is white, so it should be fine. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. One of the differences from the BioniX P120 A-RGB that is also good to notice when judging the results is the smaller offset of the rotor from the frame.There will be a tiny unevenness here and there on the P12, but it will have virtually no impact on the performance. The motor is powered by a Neodym-Iron-Boron-Magnet ring of the newest generation, which allows the new P12 PWM PST to run much more efficiently than its predecessors. The fan thus guarantees extremely efficient cooling, even with increased air resistance, and is therefore suitable for use on heat sinks, radiators and filters. In this review, I will evaluate one of the most popular fans, usually used for chassis cooling, the Arctic P12 PWM PST.
