To our delightful surprise, the Arctic P12 PWM managed to beat absolutely every other Case Fan that we own. 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.

P12 / F12 PWM PST CO => Has a PWM Connection + Daisy Chain Connection + Build for Constant Operation Even though we were perplexed that they did not manage to repeat their results, they performed excellently with 83°C on the CPU. Because the P12's are aimed at the Performance-only market, we will also cease to let their design affect our Review. 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. 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.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. 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). 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. 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 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. PDF 429.9KB ACFAN00171A - P12 PWM (White) - RoHS, REACH, PAHs declaration of Compliance - 2022-10-14 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. By doing so, we can use the CPU Temperature as an accurate measurement as the CPU temp now only relies on the Air that the Case Fans are pushing into the Case. 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 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.

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)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.
