P12 PWM PST A-RGB | Semi-Passive 120 mm Fan with - ARCTIC P12 PWM PST A-RGB | Semi-Passive 120 mm Fan with - ARCTIC
Samák on FSP Hydro G Pro ATX 3.0. From creators of the unforgettable Sure, PSUs are not really something that we have some ambitions for the future, so... While we attached the first Fan to the PWM header on the Mainboard, the short PST extension forced us to also rout the Cable of every other fan to the front of the case. it’s regular PWM, and as mentioned these are quiet enough to fase out at a distance, probably arms length is already enough and it never becomes audible from the actual use distance no matter the speed, it may be some artifact caused by a low PWM setting, maybe slightly flawed PWM controller on the board too as I imagine that may cause troubleThe 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). To summarize our findings, as long as we ignore the fact that the Fans look a bit Outdated or Boring and the short PST Wire, we cannot say anything negative about the P12's in regards to their performance. The cable is “ordinary” but solid – flat, with the wires holding together nicely. There are two connectors at the end. One to connect the fan to the motherboard or hub/controllers, and the other to daisy-chain another fan. The cable is 40–45 cm in length. Inside of the Box, we can find the Fan, a little Bag with 4 Mounting Screws, and a Smartphone Shaped piece of paper with a QR Code redirecting to the User Manual. Noctua NF-A12x25 beats Arctic P12 when it comes to silent PC cases like Nanoxia Deep Silence 8. The lower frequency of P12 is much harder to stop. With mesh cases, a lot is up to personal preference (apart from CPU cooling where NF-A12x25 shows its teeth).

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. 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.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. And in fact, our dB-meter and the Audio Recording of our Benchmarking both confirmed that there is absolutely no difference between having Anti-Vibration-Pads and not. (Or we unable to, no matter how loud we played the audio recordings) To our delightful surprise, the Arctic P12 PWM managed to beat absolutely every other Case Fan that we own.
