AUTONOMOUS CONNECTORS: 4 separate channels also allow additional RGB fans to be integrated into the system, synchronized or individually controlled Perfette per i radiatori o per i case che hanno l'intake coperto da mesh o aperto solo sui lati, grazie all'alta pressione statica, ma vanno bene dappertutto. Le PST possono essere messe a catena quindi usando un singolo header sulla scheda madre.
P12 PWM PST A-RGB | semi-passive A-RGB case fan | ARCTIC
NZXT seems to agree, as the RGB LED ring on the Aer RGB 2 is solely visible on the fan’s intake side. In other words, you’ll only be able to appreciate the Aer RGB 2’s lighting effects when they’re used as exhaust fans. That makes sense, as that’s where high-airflow fans are best used. Well, the best study would be with P14 rev. 1 vs. rev. 2, if the same motor is used across revisions and the only difference is really in the (non)presence of the hoop.
EK’s EVO 120ER connects to a standard ARGB header on your motherboard. You can also daisy chain EVO 120ERs together, allowing you to control multiple fans through one motherboard header. 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. Avendo potuto comparare direttamente questa versione "nero/trasparente" con la versione "nero/nero" abbiamo notato che le "nero/trasparente" sono molto più rumorose.
P12 PWM PST A-RGB | Semi-Passive 120 mm Fan with - ARCTIC
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. In our opinion, it’s a great time to be building an RGB rig. While fan manufacturers like Noctua still rule the roost in outright performance, RGB fans like the Arctic P ARGB series have caught up reasonably well. You’re now no longer sacrificing your cooling performance in the name of aesthetics and cool lighting effects. The low noise area has always been the hobbyhorse of Arctic P12 fans. It seems almost magical how low the volume is in the respective speed ranges. And tending to put the icing on the cake, the Arctic P12 PWM PST A-RGB are even a touch quieter. The fans from the brands Noctua, Corsair and the majority of the models from be quiet! do not stand out much in this 120 mm case fan test. Overall, these brands fill the midfield, which is not a bad performance by any means, but just not an outstanding victory that might have been attributed to them without the comparison. At least it is noticeable that the Corsair QL120 does better than the 140 mm models from the corresponding parallel test. Conclusion 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.
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) At comparable speeds, Arctic’s five-bladed fan rotors deliver higher airflow than most competing solutions, and even at lower noise levels, aside from the aforementioned rumble. It’s just that this sound is characteristic of early P-series fans. The blades are too long, flexible and made of a material with higher thermal expansion. In addition, Arctic states that the P12 also achieves higher airflow at lower speeds, which is partially true, but not to the extent that the specs suggest. At the same speeds, the P12 A-RGB’s airflow is indeed lower because there’s more hub area for the same overall cross-sectional area. This by approximately 47%. However, in terms of the rotor as a whole, this difference is not that dramatic. Subtracting the internal cross-section (hub), the external cross-section (blades) of the P12 A-RGB is only 4.9% smaller. And it is also important to note that this is in an area where the effect of area on efficiency decreases.

The P12 has larger blades compared to the BioniX P120, although it doesn’t seem like it unless one sees those fans side by side. So with the same size hub, the gaps between the blades are naturally smaller on the P12, so there is less room for airflow leakage and higher static pressure is achieved. This means that the airflow loss due to obstacle resistance is smaller with the P12 than with the P120. 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. I got some P12 Max’s but was disappointed with the overall noise distribution so I returned them (they definitely moved a lot of air but they were considerably noisier across the entire rpm range compared to the P12 CO’s I had, and one was particularly noisy when placed on a radiator – maybe I got a bad early batch). I have to admit that I hadn’t heard of the Cooler Master Mobius before the case fan review of the 120mm fans, and I was definitely surprised by them. The same goes for the MSI Silent Gale P12s, which at first glance seem similar in design to the Noctua NF-A12x25s, but perform better as case fans. Due to the lower maximum speed, they fall a bit short in the final test, but they offer excellent performance in a normal volume setting.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. While the SquA punches above its weight when it comes to cooling, it falls a bit short in the looks department. While it shares the single LED ring configuration of NZXT’s Aer RGB 2, the ring on the SquA RGB looks a bit muted in comparison. It’ll add a splash of color to your rig, sure. But compared to some of the other fans on this list, it lags behind in the looks department, at least to our eyes. I tried to find the information about this and I found that the company resolved the resonance at Rev.2. Also there are a the change at required current(0.08A->0.10A). But I don’t know the difference between Rev.2 and Rev.3. I’m only going to use them for a couple months until I’ve saved up some money for Corsair QL Fans and all the stuff you need to get the RGB to work and stuff. Enermax makes up for the single LED ring with a circle of tiny pinholes in the rear housing. It’s not much, but it lets some of the light from the front-mounted LED ring shine through. It’s a nice touch and something more manufacturers could stand to implement in their own designs.
Arctic P12 PWM PST A-RGB test – shining performance Arctic P12 PWM PST A-RGB test – shining performance
EK is well known as a manufacturer of water-cooling components, including radiators. So it’s no surprise that their EK-Vardar EVO 120ER D-RGB fans excel at static pressure. The 3.16 mm-H2O rating of the EVO 120ER makes it the perfect 120 mm RGB fan for radiators and filtered intakes. 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. Where the winner’s podium is still relatively expensive, significantly cheaper fans follow with the Arctic P12 in the new Max version and the regular variant as well as the DeepCool FK120. The two Arctic fans are a touch quieter and the DeepCool FK120 a touch stronger. In practical use, we have to say that they do not give each other much. Quiet yet powerful case fans: Cooler Master Mobius (bottom left), MSI Silent Gale P12 (bottom right), DeepCool FK120 (top left) and Arctic P12 (top right) The Cooler Master Mobius 120P ARGB are thus also the strongest RGB fans in this test run, are followed by the RGB version of the DeepCool FC120 and the ENDORFY Fluctus 120 PWM ARGB. The selection of fans is almost confusingly large. And comparisons can often only be found between a few mostly very well-known models. That’s why we decided to do a few big fan tests where fans compete against each other in different areas. This is the 120 mm case fan test, where more than 30 different … (Weiterlesen...)During the development of the new P12 PWM PST CO, 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 CO is particularly suitable for use on heatsinks and radiators. 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. The box has QR codes printed take you to Arctic support with touch easyy English, Spanish, French, Italian, Polish, Dutch language support. Convenient. Kind of like they thought that someone might have their computer apart and have a question. The price-performance victory is captured by the Arctic P12, P12 Max and the DeepCool FK120, which hardly leave any performance on the line compared to the pure winners despite the much lower price.
Great Deal
