The P12 PWM PST A-RGB 0dB has 12 digital A-RGB LEDs in the fan scar. These can be controlled independently of each other and are compatible with the common A-RGB standards of leading motherboard manufacturers. The fan can thus be fully illuminated directly via the A-RGB mainboard connector or via an external controller and synchronised with the illumination of other hardware. Thanks to an alloy/lubricant combination developed in Germany, friction within the bearing is reduced and greater efficiency is achieved. In this way, less heat develops, less bearing noise is generated and the service life of the fan is extended.

Stand out point: If I had to narrow it down to one thing, I would say the fact they gave us a generous amount of cable and the connectors on it will allow you to Daisy Chain.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. As for the comparison of the paper specifications of the P12 and P12 A-RGB, I really don’t see the technical reason why the static pressure of the P12 at the same speed should be higher by… what, 25%, when at a speed lower by 200 rpm it should be +19%? It makes sense to me the other way round. Of course, a higher static pressure is indirectly caused by the larger hub, if only because it leaves a smaller empty area between the blades. The smaller the fan format, the higher the static pressure per unit of airflow. With the P12 A-RGB, the hoop itself also increases the overall pressure (i.e. static pressure as well) to a certain extent, as I mentioned in the article. This is a good study of the effect of rings. The blades are a bit shorter so there’s less airflow at the same noise level (despite higher static pressure), but it suppresses blade vibrations very effectively, improving the noise profile for fans using flexible blades. A surprisingly high performance has the DeepCool CF120, which achieved the best temperature results at the RPM, but due to the higher volume they are found a bit further down the list. The very loud and weak Alseye X12 attracted negative attention. Case fan at uniform 31 dB(A)

In the budget range, I had particularly counted on the Arctic fans, with the P12 and P12 Max also delivering upper-class performance at a very low price. The Arctic F12s unfortunately don’t quite make the cut of their 140mm sisters and lose out significantly to the P12 models. Unfortunately, I cannot agree with this statement even now. The extra details that Noctua has often stand out more with relatively higher speeds. Whether it’s Flow Acceleration Channels, Stepped Inlet Design, a significant narrowing of the gap between the blade tips and the frame or Inner Surface Microstructures. These elements counteract the shortcomings that become stronger with increasing pressure. The fact that the NF-A12x25 gives excellent results at low speeds is largely due to the fact that the operation of the motor and blades does not create any noise, so at this level there are no such pronounced limitations as with other fans, and the NF-A12x25 fits into the same noise level at higher speeds. Thanks to the 4-pin connector, the RPM can be regulated in a broad spectrum via PWM. In this way, noise is kept at a minimum while maximum cooling performance is guaranteed when needed. The P12 PWM PST is able to switch into silent passive mode when PWM signal is below 5 % due to its new motor. This allows working at your PC in complete silence without any unwanted noise. Additionally, the 120 mm versions of the new P-fans can be easily mounted to existing Freezer 32 and Freezer 33 models. The “PST” in the name stands for “PWM Sharing Technology,” which means that each fan has a second female 4-pin slot for daisy-chaining multiple fans. It’s a welcome bonus that should help keep your motherboard headers free.With a wide speed range and the innovative PWM Sharing Technology (PST), the fan speed of the P12 PWM PST A-RGB 0dB can be controlled synchronously with all other fans. This reduces noise to a minimum while guaranteeing maximum cooling performance. Of course, performance isn’t the primary criteria for ARGB fans; aesthetics matter too, and that’s where these Arctic fans fall short slightly. Don’t get us wrong, they’re not bad looking at all, but you may want to look at other options if if you want flashy LED rings and complex lighting setups.

well, it did once the noise became high enough to make all the finetuing Noctua does irrelevant, at 31dB(A) and below there’s no competition, and I hope we’ll see these lower noise targets soon” In this test, the temperatures and the noise development are added together. Therefore, it is not surprising that the fans that combine good performance with low noise are at the top. Cooler Master’s Mobius 120 in the regular and RGB versions are at the top together with MSI’s Silent Gale P12. Those who would have expected the Noctua NF-A12x25, which is considered revolutionary and has received a lot of praise, to be at the top will be somewhat disappointed in this case. While these offer good performance as case fans and are quiet, they are definitely beaten by other models in this area. Within all testing of all the fans, there was only ever 1°C difference between them. So, the fan is no better or worse at the specific tasks than any other fans we tested.
And one addendum for the discerning reader who will scroll through the comments here and there and might ask the same question as one of the readers of this article in another language. Namely, why the BioniX P120, being more expensive, often achieves a lower airflow than the P12. We discussed a bit in the opening chapter that these fans don’t have the same rotors, but I didn’t want to pay any extra attention to that in the conclusion (these aren’t fans that are in any way competing or that you’ll be deciding between). 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.

The be quiet! Silent Wings Pro 4, ENDORFY Fluctus 120 PWM ARGB, and Arctic P12 are not the overall winners, but deliver very solid results in all tests. At the lower performance end remain the Alseye Xtreme X12, which not only provide the lowest performance, but are also many times louder than the next two fans at the lower performance end. The be quiet! Shadow Wings 2 and the Fractal Design Aspect 12 do not offer high peak performance, but they remain quiet enough on uncontrolled full power that they do not attract negative attention.
