It would be unfair to highlight only the exceptional radiator performance of the Arctic P14 Pro A-RGB fans in the title. They’re remarkably appealing in other scenarios as well. Whether they’re more attractive than the Fractal Design Momentum 14 RGB is something you’ll have to judge for yourself. In many respects, these new fans have the upper hand—though it must be said their manufacturing costs are somewhat lower.
Our analysis of the Arctic P14 Pro (A-RGB) fans begins in the reverse order from how we approached the smaller variants (P12 Pro/A-RGB). Specifically, with the more expensive (and better-equipped) illuminated model: the white Arctic P14 Pro A-RGB. Its product code is ACFAN00318A—you can use it to locate the fan easily in stores. All A-RGB variants share the same lighting implementation, which radiates from the hub and evenly covers the entire surface of the blades. This provides a strong foundation for highly visible illumination. In the case of the P14 A-RGB, it absolutely holds true—its lighting is impossible to overlook, yet still dimmable to a low brightness level that shouldn’t be distracting even at night. The RGB brightness range is broad and flexible.
The key to this fan’s high cooling efficiency lies in its new aerodynamic design—Arctic has now switched to a seven-blade configuration. Previous generations featured only five blades, and this increase serves two purposes: higher static pressure (and thus better airflow in more restrictive environments like radiators), and reduced blade surface area, which helps suppress torque ripple.
Shorter blades made from the same material and with comparable thickness tend to vibrate less—especially important at high speeds. That’s another strength of the P14 A-RGB, which spins at up to 2500 RPM—an undeniably above-standard value for the 140 mm form factor. The older model (P14 PWM PST A-RGB) topped out at “just” 1900 RPM, even though it already featured the blade ring that’s also part of the P14 Pro A-RGB impeller. This ring, located at the blade tips, reduces vibration and helps suppress undesirable turbulence, which helps achieve higher pressure in critical areas—ultimately contributing to increased airflow.
One question is whether airflow might be higher if the blades were longer by the amount of thickness taken up by the ring. Either way, any differences in this regard are likely minimal, and the greater contribution of the ring lies in reducing the vibration of otherwise relatively long blades with prominently curved leading edges. You’re probably already familiar with similar impeller designs, and you’ll know they’re characterized by high aerodynamic efficiency. Various external features can still improve airflow or reduce noise, but the core design of the P14 Pro A-RGB is undeniably solid.
The fan’s static pressure is also notably high—due in part to the below-average spacing between the blades. It’s only natural, then, that this design is well-suited for pushing air through obstacles. In obstacle-free scenarios, where the benefit of higher static pressure is less pronounced, airflow may be relatively lower. This is also due to the impeller hub, which occupies a fairly large portion of the total cross-sectional area of the P14 Pro A-RGB. The oversized impeller hub here may be tied to the need for a more stable center. The impeller itself is relatively heavy, and the ring adds to its overall mass. For reference, the total weight of the fan is around 234 grams.
The rear label not only shows the fan’s name but also details the motor and lighting power ratings. The motor’s maximum current draw is rated at 0.35 A, and the LEDs draw up to 0.4 A. Both figures are more or less accurate. With RGB set to “white” at maximum brightness, power draw was measured at 2.24 W, and the motor at 4.53 W. Typical operating consumption is of course lower (than the motor’s rated output), around 3.7 W. The exact number depends on the resistance of the environment in which the fan is operating.
Also worth noting are the rubber corners on the frame, which help dampen vibrations that would otherwise transfer to the heatsink/radiator structure or the case. These corners weren’t present on the non-Pro “P1x” fans and were only introduced in the “Max” variants.
One last thing: the A-RGB versions of the P14 are labeled “PST,” which means they come with dual connectors for both the fan motor and the ARGB LEDs. One connector is for connecting the fan itself, while the second allows you to daisy-chain additional fans. The cables are fairly long—usually between 40 and 50 cm.

If we’re looking for other 140mm candidates to compare this to, it would be nice to see how you rate the InWin AN series; I know from practical experience it seems to slurp through foam filters with aplomb.
They have a min RPM of 900. For me that’s a massive dealbreaker
I assume we’re talking about InWin fans? Yes, for a 140 mm model, even 900 RPM can already be aerodynamically noisy for some people. 🙂
That is only if managed by PWM mode, not DC (voltage).
I argue it doesn’t matter that much today as every 4-pin (PWM-mode) fan can also be controlled by DC-mode by the motherboard and most software used.
Voltage (DC) is somewhat less fine-controled (steps), but still good enough to not notice the difference in everyday usage.
Basicall all motherboards support both modes and using LibreHardwareMonitor (used by fancontrol (fancontrol is the GUI)), makes usage of both modes easily.
https://www.cybenetics.com/evaluations/fans/50/
The issue here I see is that no one except hwbusters have tested these Diamond-rated airflow-baddies yet, and they only relied on PWM-mode (for finer granularity testing obviously). 850 RPM minimum thus.
So we don’t know – unless e.g. Commodore Jeep-Eep tells us – how they behave in DC-mode.
You’re right—with some fans, DC voltage control results in lower speeds than PWM control. However, it can also be the other way around—PWM can sometimes achieve lower speeds than DC. It’s individual. As for how it works in the case of the mentioned InWin fan, Commodore Jeep-Eep will have to clarify. Of course, motherboards have the option for DC control, but sometimes the voltage they can supply to the fan is too high and does not reach the minimum at which the fan can spin only symbolically, at low speeds.
…and on the other hand, some fans respond perfectly to PWM and with DC regulation they click or have fluctuating RPM, etc….such as the TT TF 12Pro. 😉
Under my use conditions I’ve yet to have anything I’d call objectionable, though I do tend to be a ‘set the fan curve aggressive because better to burn bearings then sound’ type.
Should read: silicon
Good day,
answer the question below please about these Inwin AN140 fans DC-mode behaviour.
Starting fan speed, minimum fan speed, maximum fan speed, erratic behaviour, how fine-tuned is the control?
Thanks!
“slurp through foam filters with aplomb”, I really don’t understand what that means 😀
A new explanation please. You wanted to inform they make loud noises through nylon dust filters, grills etc.?
Nylon filters should not significantly increase noise; in fact, they may even have the opposite effect—achieving lower noise. This is typically at lower airflow (since part of the filter’s surface is always blocked—otherwise it wouldn’t work, haha… and that results in a drop in pressure/flow). Higher noise is unlikely because the structure of a nylon filter usually does not promote turbulence that increases noise. On the contrary, it tends to smooth airflow, eliminating microturbulence at the intake and thus reducing noise. It doesn’t always happen, but sometimes, with certain aerodynamic fan designs, it does. 🙂
They are insanely loud, like drown out a sound bar loud.
As I mentioned in the previous comment—the way to lower noise is by reducing the RPM through regulation.
Can I add non-ARGB fans to ARGB P14 PRO on a radiator? Or should they all be of the same kind?
Mixing the fans (P14 Pro with P14 Pro ARGB) is definitely possible. From a technical standpoint it might even lead to more attractive results, since each variant at comparable speeds will produce slightly different tonal peaks, making the cooling a bit quieter overall. So yes, go for it—if you don’t mind the aesthetics and the fact that not all the fans will look the same. 🙂
My InWin 140mm Neptunes bottom out at 900rpm, but I have to run them at a minimum of 1100rpm to avoid quite loud bearing rattle on my top radiator fans. I plan to replace them with these Arctic ones.
Neptune AN140? Are you sure the sound you’re hearing comes from the bearings? Quite a few fans become noisy at the very bottom of their speed range, where the motor itself starts to struggle—right at the threshold of what it can reliably operate at. This is especially common with DC control at low voltage. In any case, yes—using Arctic P14 Pro A-RGB fans with PWM control should allow you to reach significantly lower stable speeds, without increased non-aerodynamic noise. 🙂
It is not in the “Fans Archivy”! Please, fix that.
We’re aware of this. It’s not something we haven’t considered, and it can called a “bug” on the site. Even though the article has the correct category, unfortunately it doesn’t appear in that category’s listing. We hope to fix this in the future. At the moment, there’s nothing I can do about it. I’m sorry, but that’s just how it is.
Lol I have these fans… they are so noisy I’m replacing them not even a week later. The build quality is exactly what you think 100$ will get you. They are exactly what they should be, cheap fans with decent performance that takes a hit on literally every other factor. Fans are ugly as sin. They sound like a mf wind turbine which is completely unnecessary with an aio of any size. It is crazy after buying these hearing all the hype they still get. By far the ugliest thing in my pc right now. You can see through the front plate to the ugly magnetic connector. The fittings are plastic. There’s like 50 wires coming out of the pump if you actually want to control your fans and pump separately. Lmao I could just keep going for days……
The Pro fans have a lot better noise profile in the 800-1200rpm range compared to the regular and A-RGB versions. But they have other issues in the lower rpm range. Staring behavior is terrible, they go to high rpm and then back down.
I returned them too, I rather buy Noctua NF-A14x25 G2 PWM or NF-A12x25 G2 PWM even if they cost a ton more, I already spend half the money on Arctic and quality is very inconsistent, like 8 out of then has weird motor noise, F12/F14 was way better in quality.
It will probably depend a lot on how each fan interacts with the type of obstacle. That is, in terms of acoustic profile… of course, some differences between ARGB and non-ARGB versions due to materials exist, but it’s definitely nothing dramatic if we’re only talking about the fan sound—without an obstacle. With an obstacle it can, of course, be different. The number of possible situations (with obstacles) is basically endless. There are really many possible combinations. 🙂
Yes, the Arctic P14 Pro A-RGB are noisy fans if you run them at maximum speed. After regulating them to lower RPMs, which is possible (so everything is fine), they don’t have to be that loud anymore. You just need to slow them down. This can be done via PWM or DC. 🙂
you’re really not too smart…lol 😉
I wouldn’t go so far as to say Erik isn’t “smart,” but it’s true that those fans (Arctic P14 Pro A-RGB) are more attractive than the situation described in the comment above might suggest.
Thanks for the Artical, only really two questions, how much are these and what’s the noise (db) rating? I could only see N/A. I’ve ordered and recieved two x 140mm extra case fans because my gaming temps were insane. These are Thermaltake Riing blue leds only spin max 1400RPM but make max 22.5dba. Good price at £23.00 the pair. I was reaching silly temps with an I9 14900k and RTX4090. Changing cpu to a Ryzen 9950X3D and upgrading from a good brand 360mm to NZXT 420mm aio should also help. TY for the article once again.
You can find the answers to both of your questions in the test. N/A is not indicated in either of these cases. We only use that label for the MTBF value. 🙂
Hello,
I have a question : which one is better between the Max and the Pro ?
(as a WC radiator fan, and as a case fan)
I should say it’s strange you cannot achieve low noise with P14Max, because it can run at very low speed.
The P14 Pro will be the more suitable fan for your use case. I’d say in every respect. The P14 Max doesn’t allow for such low speeds (as the P14 Pro does). At least, not in the revision we tested (and that revision very likely hasn’t changed to this day?) via PWM control. 🙂
Not exactly scientific, but I’m getting a super annoying whine, almost like a very faint vacuum cleaner at lower RPMs.

The bottom graph is my ambient environment, the middle graph is the fan at 20% PWM, and the top graph is 32% PWM where I can most acutely hear the noise. Unobstructed open air BTW. I think the noise I’m hearing is the one right around 4200-4400hz
It’s the same with all of my samples and the more I have in my system, the more they amplify that frequency. I can hear the noise from ~23% to ~34% PWM. It’s a shame because that’s an important range I would otherwise like to make use of.
I see on your testing there’s a small spike around 4800Hz on your 39dba chart. Do you think that’s what I’m hearing? What is usually responsible for a constant 4200Hz noise that occurs only within certain RPM ranges?
Thanks in advanced!
Thank you for the message with the detailed specification of the testing environment.
On your spectrogram, the tonal peaks appear mostly at lower frequencies, which is also illustrated by our graphs. Whether it is 117 Hz or 175 Hz also depends on the fan speed setting.
It is true that we do have a tonal peak before 5 kHz in the graphs at speeds around 1000 RPM, but its intensity (noise level) is relatively low. Nevertheless, it cannot be ruled out that with some particular setting this tonal peak may become stronger and that it is what you are hearing. It is possible. 🙂
