Product Information

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. High Quality Bearing Thanks to an alloy/lubricant combination developed in Germany, friction within the bearing is reduced and greater efficiency is achieved. Modifying” a cooler by replacing the fan with a relatively more efficient model may not always lead to the desired result. 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.

In addition, the P12 PWM PST A-RGB 0dB has rubberised contact surfaces and thus reduces audible vibrations to a minimum. Due to sinus-magnetizing the new motor only creates about 5 % of the vibration from the commutation of a regular DC motor without a filter.Fewer reactions to the “rumble” of the CO variant could perhaps stem from the fact that it is probably a less widely used fan, owned by fewer people, so there will be less feedback/less negative criticism of the acoustic properties? Note: Your question will be publicly visible and can - in addition to our support - also be answered by a member of our community. to 1800 RPM regulated via PWM PST Thanks to the 4-pin connector, the RPM can be regulated in a broad spectrum via PWM. 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. If the blades were smaller, a lot of air would escape through them, which would reduce the airflow the more resistance the fan would have to overcome.

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.

Optimised for Static Pressure During the development of the new P12 PWM PST, special emphasis was placed on a focused airstream and thus a high static pressure. 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.

This version of the P12 also supports PWM Sharing Technology (PST) so that the fan speed of the P12 PWM PST can be synchronized with other fans. To be honest most of the fan manufacturers claims can be taken with a pinch of salt and the only way to see how any of them really perform is by proper fan reviews (if there are any). Sometimes you will get significantly less improvement than you would expect, other times you may even be worse off.This means that at equal noise levels, you will achieve lower cooling performance, and it doesn’t really matter what fan you use.
