The 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).

If you want to control several fans from one unique motherboard header, you can use PWM splitter cables such as the ARCTIC PST Cable rev2 . We however recommend to limit the number of fans per header to 5 as the current may be limited to 1.0 A per header (please refer to your motherboard manual). So overall, on the performance side, the Arctic P12's are an excellent choice for anybody that does not want any unnecessary RGB features in their build. Additionally, they did manage to keep the noise level pretty low, and even be "un-noticeable" in the lower 50%s of their PWM Speed. To summarize our findings, as long as we ignore the fact that the Fans look a bit Outdated or Boring and the short PST Wire, we cannot say anything negative about the P12's in regards to their performance. At a first glance, the Arctic P12 Lineup may be overwhelming, but we will try to make it as clear as possible. Arctic's Lineup of 120mm Case Fans is grouped into 2 big Product Lines, the P12 Series & the F12 Series.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. P12 / F12 PWM PST CO => Has a PWM Connection + Daisy Chain Connection + Build for Constant Operation This allowed us to run each of the Fans off one single PWM Header on the mainboard while connecting each of the fans together. 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. While the F12 Series is Airflow optimized, it spins way slower (1350 RPM) and produces way less air pressure, but can push a lot of air for such a slow-spinning fan.

After letting Heavyload grill the CPU, we came to the following results while the Fans were spinning at 100% PWM. While benchmarking the Fans, we also tried to test if their claims were true. For this, we simply cut the Anti-Vibration Pads of other fans into an acceptable shape and added them to our Benchmark schedule.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.

The P12 Series is pressure optimized, meaning that the Air that the P12 Fan is pushing has a higher pressure, resulting in a better passthrough if the direction it blows is restricted, like by a Radiator or Filter. Because the P12's are aimed at the Performance-only market, we will also cease to let their design affect our Review. Even though we were perplexed that they did not manage to repeat their results, they performed excellently with 83°C on the CPU. While Benchmarking, they managed to outperform everything we own under full load and managed to keep a very good position while letting the Fans spin slower.As we used the P12 PWM in their "PST" Version, we were able to make use of their "Power Sharing Technology". This PST Plug basically adds an additional 3-Pin Output to the cable of Each Fan. 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. Even though the Arctic P12 Line-up does not offer any RGB-Like features or any "nice-looking" design aspects, they do perform excellently. While we installed the P12's we did notice a small thing that could have been better thought through. Even though the PST (Daisy-Chain) system was very useful while mounting them, the attached extra wire was way too short.

The speed of P12 PWM can be adjusted using PWM signal from the motherboard. Please follow this procedure to adjust the settings on your motherboard. After Unboxing the Fans, we immediately noticed that there were no "Anti-Vibration" Pads to be found.Once we turned down the PWM Speed to 50%, the P12 placed themselves just behind the Noctua NF-F12 's and Inter-Tech RS-14 (Yes a 140mm set) At first, we assumed that this was one of the reasons why these Fans could be so cheap, but upon investigation, it turned out to be a feature.
