Good but slightly noisy
These are excellent fans in terms of RPM range and static pressure. They are also relatively quiet at higher RPMs, up to 2000, compared with other fans - yes anything spinning that fast will be noisy, but these are quieter than the stock Corsair SP140L fans on my H115i radiator. They are also more efficient at higher RPMs thanks to the 3 phase motor technology. However, at lower RPMs there is a constant noise coming from the 3 phase motor, which is louder than the air movement sound. It is on par with the constant high pitched hum that I get from my H115i pump on the CPU, which is equally annoying if you are at all close to your computer. The noise from the PPCs is more like a grinding/churning noise, which disappears at higher RPMs but then is replaced by noise from air movement, so the fans are never really silent. The 3 phase motors might be better suited to a noiser fan overall than fitting them on a high SP silent fan. Reviews are mixed on these fans as to whether they are noisy or not, and ppl's verdicts are subjective, as some ppl have their computers under the desk and/or are more 'laid back' and don't really notice finer background noise whilst others are more detail oriented or OCD and it drives them nuts. Whilst a youtube review showed these PPC fans matching the low noise of the ordinary NF-A14s at equivalent RPMs, I asked Noctua themselves and they said that the PPC fans were noisier at lower RPMs, from 800 to 1200 but otherwise the performance at equivalent RPMs was identical. The RPM range of the standard fans starts from a lower value, at the same voltage, and you will get lower RPMs from the standard fans compared to the PPCs if you don't use a voltage stepper of some kind to lower the voltage of the PPC fans. Lower RPM = quieter obviously anyway, without the constant churning noise. I chanced it from the reviews and regretted it and sent them back and am now using NF-A14 chromax instead (I hate brown fans lol they are hideous). So overall, these are great fans, but just not suited to a rig that is really meant to be quiet.
