Noctua NF-A14x25 G2 - The Optimization King 👑

[@STSYT]

Note: 05:44 The Noctua NF-A12x25's frame isn't made out of LCP either. No idea why I thought that was the case.

[@lazylemymaitland6996]

We are getting the chromax G2 cpu cooler soonish, I think it was Q1, but it’s probably Q2, I’m not checking but they have the roadmap

[@gab882]

same feeling. i don't want this Noctua branded colours. ruined the overall look of the pc case.

[@dylanmonahan5909]

​@@gab882Noctua's colour scheme is best suited to mesh or solid case sides haha I guess the brown could match well with darker wood tones, which are growing in popularity, but the cream kind of ruins it as those cases are typically black. If Chromax does come in Q1, that's an acceptable delay (as I think they earnt the right to fly their colours at launch), but any more than a couple of months is just annoying and will just lead people to other brands.

[@DM-eq4rs]

Thank you for the hard work and time you have put into providing us with this content. I really appreciate professionals like you. Hats off to you.👏👏

[@tomhollins5303]

I think the PPs may be about perceived noise with respect to tone from interference rather than absolute average noise

[@dylanmonahan5909]

Definitely. Perceived noise in terms of the A-weighting (ie DbA) and just in terms of personal preference. Hearing them side by side with the OGs (in recordings), I prefer the older ones. I think it's the kind of difference that you can't properly assess in a recording though, as harmonic resonances will shift based on so many factors (including room modes etc.) making it practically impossible to rate in isolation and out of the intended setting. Either way I think it's cool that they're trying new ways to keep pushing the envelope.

[@4Leka]

Thanks for including the P14 ARGB. People deserve to know about it, since it's not identical to the P14.

[@guycxz]

Had a look at P14s again and yeah, the A-RGB version goes 200 RPM higher than the normal PWM PST, and then there is also a P14 max that goes up to 2800 RPM. That's a lot of P14s.

[@4Leka]

@guycxz The ARGB version has a different fan than regular P14 as well. The tips are connected with a ring. That leads to improved acoustic performance.

[@C-M-E]

On axial fans, the overwhelming cooling is happening at the outer edges of the fan profile due to centrifugal action, which is also a design principle inherent to jet engines compressor and turbine profiles. Having an aggressive incident angle on the innermost edges closest to the motor does almost nothing other than slowing down rpm, so having a relaxed angle until about midpoint makes tremendous good sense towards better performance. On using Fan Control, there's a toggle box in the settings that allows you to override the motherboard BIOS settings so you don't have it trying to fight the first layer settings. Checking that box and using either custom profiles or manual intervention, you won't see the cycling problem when setting up and running fans independent of the BIOS PWM settings.

[@Moserah88]

You will also review the RX MAX in the future I would really like a comparison with the RS MAX

[@Apoz]

I like the precision in their "warnings". It's not overcomplicating.

[@dylanmonahan5909]

Great review! You got my like and sub. Cheers

[@madness5157]

Listening to the sound comparison. I find that the older sounds better, its louder sure and is louder sooner. But the noise profile is lower, less high pitched if that makes any sense. Which i think is less irritating to the ear.

[@dylanmonahan5909]

This is what I heard too, though I'll admit this was via my tablet speakers. The higher frequencies might reflect within a case more, becoming less perceivable by the time they reach us. In isolation, the lower pitch noise profile isn't generating resonances, which can often feel like intrusive inner ear vibrations (think of a car with one window partially down)... maybe in that context the newer matched pair fans are a welcome compromise.

[@Clove_Parma]

Just popped one of these in my NZXT H1 V2 to upgrade the CPU cooler. So much quieter, and getting better temps than OEM. Very happy

[@Apoz]

I'm really looking forward to the NF-A14x40

Rocking 30 chroma A12s in my 1000D rig, push pull setup.

[@tomhollins5303]

If you are trying to min / max your build then directing the flow to the outside might well be a down side. You would want to add a plenum in front of a rad to get good flow across a larger area of radiator fins.

[@OTechnology]

Since the motor is a closed loop motor that tries to always go to a certain RPM depending on the PWM %, if the fan header on the board is dropping voltage instead of PWM % then the motor will see a drop in torque and RPM which it will try to compensate for. This fan is not controllable properly via voltage control is how I understand it. Essentially the motor has a table in the firmware that correlates PWM % to RPM, so it will always target an RPM number depending on the PWM % input.

[@Kapono5150]

Waiting for the black one

[@WeAreMovieMakers]

Waiting for the black PP?

[@Apoz]

Pointing the fan at the db meter doesn't make sense, you introduce noise due to air hitting the microphone. You should put it to the side of the fan to actually hear the sound of the fan it self.

[@Tealc2323]

In some situations, using push-pull fans on a rad can create a sound pitch that's super annoying. It happened to me and I was forced to control the fans separately to set different speeds for each. And even then, I could only move the pitch to happen either at higher RPM or at lower RPM, but never get rid of it for the entire RPM spectrum.

[@Franciscoxds]

Why no p14max in noise to performance radiator benchmark?

[@elteacher0223]

great work!!! thanks for sharing!!!

[@blahorgaslisk7763]

The PP version in tandem use question is interesting. The idea of having the two fans spin at slightly different speeds changes the sound in one particular way. With two fans at almost exactly the same speed you will hear a wow sound. It is more noticeable the closer to each others speed they fans are. At the exact same speed this should be gone, but that hardly ever happens. Instead it can get really slow in frequency. with about 50 RPM difference there will still be some of this wow sound, but it will occur at a slightly higher frequency. I'm to tired to calculate the frequency but I bet it's a less frustrating result than what you get with the fans spinning at just a few RPM difference between each other. Another thought. It might be interesting to switch the order of the PP fans. Put the fifty RPM slower fan at the front and the faster in the back and check how that impact the sound. Also chech the speed of the fans. Are the fan speed difference the same with the slower fan in front as with the faster fan in the front? Thing is the front fan will accelerate the air, which makes the work easier for the fan in the back. Does that make it speed up or does the controller in the fan slow it down to the original speed? that will also change the quality of the sound and might change the wow frequency.

[@ibelieveinjesusinmyspareti2861]

I'm going to be honest, we've all found ourselves in a that place where we just bought one product and it has some weird issue about it, what happens very often (i assume) is that people with such expensive fan have bought a cheap case and found it to be too loud, then find this and for fomo or whatever put it their case and it makes a weird noise, maybe because the case's panels are way to flimsy but the mileage does vary a lot for everyone i guess this is something we can all agree on. So.... i kinda understand why, this is the sort of thing they probably get inquired about all the time. That said screwing a screw right ain't that hard.

[@flokayseven]

Sorry but all the delays for this result? And Corsair just comes out with the RS140 Max which is better in every aspect including the LCP frame and cheaper... I can't take Noctua seriously anymore....but as for you, you really are one of the best review channels I know, I hope you keep growing

[@klipk7296]

these are cool and all... but I really want to see Noctua have a go at 30mm+ thick fans like other companies have been doing

[@Paddydapro]

noise normalized tests would have been great

[@musicismypseudonym]

0:02 Nokia is a fan manufacturer now? ... just kidding :)

[@lonelymtbrider3369]

The old one has a lot louder motor humming noise (or whatever it is) than the new one

[@Mintor94]

I'm amazed how good Arctic's P14 ARGB are. The thing is Noctua is tryharding a lot with their G2s, all these little embossed and indentations in both the frame and impeller, LCP, lots of scientific explanations, while Arctic is just kinda sitting there and doing everything almost as good, for a fraction of a price. However this closed-loop RPM control is a great thing and should become a standard.

[@westcliffbrugger]

The arctic's Sound Profile ist completely shit. Sorry to say. Tried several models. Everyone had terrible humming and side noise.. This ist why high end manufacturers Like noctua start to finetune noise characteristics. For people who want an high end silent build.

[@jojosworlds1208]

Yeah, but Noctua's RND helps the whole industry. And you don't buy Noctua for having the best price to performance, you buy them for good noise characteristics and longevity.

[@ouki4925]

Where’s the P14 Max fan? 😭

[@sk8r4lf138]

Noctua had to postpone it so many times because they couldn't believe the fans coming out of China competing with their $40 fans for $8

[@MrJohannson]

I hate the high pitch noise you get with the new ones... In fact, I'm hearing some form of this noise on more than two 140mm high static pressure fans out there Upd: since I'm getting notifications for likes on this comment, I want to add that part of the noise was due to turbulence caused by fan mount brackets on my Meshify C, as soon as I cut them off, the noise profile got much better

[@tomhollins5303]

Please Noctua can you make a 30mm thick version now. (Obviously by "now" I mean sometime in the next 5 years.)

[@gab882]

i thought the "pp" version would be it.

[@Walhor]

When someone asked on their youtube page they said they had a "special" fan on the roadmap in 2025. So hopefully its a 30mm

[@squatch545]

But does it come in pink?

Noctua fans are for those like me who want under 20dBA noise. I don't want to hear my PC even when I'm gaming at night so I can use HiFi open-back headphones. We have silent fans, massive WC loop for CPU+GPU, HDD replaced by SSD/NVME, and fanless or 0 RPM PSU. The only thing that's missing is GPUs without coil whine.

[@PainIs4ThaWeak85]

21:28 🤣

[@photonboy999]

*MOST PEOPLE don't know this, but...* If you run the OLD Noctua fan at 400RPM it is inaudible from a few inches away. This NEW fan is 10% more inaudible... it's a "joke" to demonstrate people need to carefully consider their use case. My Noctua NF-A12x25 fans on my graphics card (I modded it) are dead silent when gaming because I thought it all through. As are my CPU and case fans. On an old "Antec One Hundred" that I like because it has a COFFEE CUP holder... new fans are great, but the goal is a silent PC. You gotta do EVERYTHING right to make it worth the price of expensive fans (and there may be no point).

[@AlmightyGTR]

Keeping my p14 for a very long time I guess. Noctua is good, but Arctic does it at a price I can afford.

[@leviathan5207]

A 5 pack of Arctic P14 is less than a single one of these... Nah, Noctua, this ain't it.

[@adorepumpkin]

Thx 🙂

[@squatch545]

So slightly worse than the Silent Wings Pro 4 on radiator?

[@hotbox76]

The PWM issues you noted is a motherboard issue. You should always change your fan setting in your motherboard to PWM, and not leave it on AUTO, for all PWM fans in every motherboard, as the behavior can be erratic as you noted. Not always, but why leave it to chance. Always just set to PWM on every motherboard, and you'll be fine 100% of the time.

[@user-ib8pv3op9s]
