Noctua NF-A14 iPPC-2000 PWM, High-Performance Industrial Fan 140mm

Using four of these in push/pull on a Corsair H115i radiator and I am loving them. Gives truly exceptional flexibility between near silent to quiet performance from 550 to 850rpms via PWM control. These can also move air with authority at 100% but noise does begin to be a problem. Although with four working together they are moving around 200 cubic feet per minute with essentially just the sound of rushing air. The 3 phase motor, Self-Stabilizing Oil Bearing, and rubber corner inserts work well to help mitigate unwanted vibration. My personal experience with their cooling capability while paired with the Corsair H115i is that while using a PWM hub and Corsair's Link software absoloutely surpases the stock Corsair 140mm fans. They cool the radiator more effectively and quietly. I can usually just keep Corsair's Link software at quiet to balanced which results in water temps not going above 29 degrees C in a 68 to 70 degree F room. This will keep my overclocked I7-5820k (4.5GHz at 1.31v) under 60 degrees C for gaming and even some other CPU intensive tasks. I have these fans mounted as an exhaust for my case. Pros: - Top quality construction materials - Vibration isolating rubber inserts - Smooth PWM control through entire RPM range - 3 Phase motor - 150,000 hour MTBF and 6 year warranty - Square frame for better performance on radiators - 4.18mm H2O of static pressure - good for use on radiators - 107 CFM (182.5m^3/h) open air flow rate at 31.5 dB/A Cons: - Cost, but you're getting top of the line - Higher noise output than usual for Noctua but that can be remedied with PWM control - Stock vibration isolating rubber inserts are still brown, although you can get other colors Bottom line: You are getting great fans that will last for years with a warranty to match. Their performance to noise ratio is tough to beat and they deliver exceptional cooling when circumstances require exceptional solutions.

As the title suggests is this $30 fan worth your money? I've compiled some figures that I find interesting and hopefully they will help you in choosing. I purchased this fan to upgrade the NZXT FX-140 PWM fan that came with my Kraken X40 liquid cooler. It was between this fan and the Noctua NF-A14 Premium Quiet fan. I got the PPC version because of its superior static pressure and wider range of RPM, while hoping I can find the perfect balance between cooling performance and sound. Due to the design of my Ibuypower Revolt Mini ITX case there is no room for a case fan. My Kraken X40 Liquid Cooler and its single 140mm fan is the only thing I have extracting heat out of the case. So with that in mind I needed something that had very good static pressure and could hopefully be quieter than the stock fan my cooler comes with. Even the fan intake is obstructed by the CD/DVD Drive, making a high static pressure fan even more important. Based on the specifications the Noctua should easily out-perform with lower RPMs and more pressure. My method for testing might not be the most scientific but the results are repeatable and I'm confident in their figures. Your numbers may vary based on your own system, location, software and tools but my purpose is just to compare and demonstrate the various properties of this fan compared to the one it is replacing. Software for testing ~ NZXT Kraken Control I can manually control fan speeds using the NZXT software as well as monitor liquid temps. Fans will be running the stock 12 volts. ~ Intel Extreme Tuning Utility Intel Extreme Tuning Utility allows me to test the cooling performance gains if any. Each Stress test will run for 10 minutes, waiting until liquid temperatures settle back under 37c before testing again. ~ Sound Meter via Smartphone App This is an application that turns your smartphone's microphone into a Decibel meter. The decibel reading won't be an exact representation of the fan dBA but it will give me something to compare the sound of the two fans I'm testing, while removing my own ears from trying to guess which one sounds quieter. The fan will be installed within the computer with the case closed. The computer is inside its own cabinet within an enclosed entertainment center (backing removed). The phone is about 6 inches away from the computer itself and not the fan.

Conclusion The Noctua fan only has 7 blades with a gap large enough to fit a finger between them. This is by no means a quiet fan, anything over 50% fan speed is quite audible but its smooth operation makes the noise less annoying even at 100%. It's build quality holds up to its reputation and the results are in black and white. This is quite an expensive fan ($30) but for me it offers a lot of advantages over cheaper alternatives. For my purposes, and lucky to only need a single fan, I feel slightly ok with its price but of course wish they were a little less expensive. Open Hardware Monitor and Kraken Control both show the Noctua fan reaching maximum speeds of 1850 RPM, so within the +/- 10%. The fan simply outperforms the outgoing fan in every category offering lower temperatures, RPMS, and noise. The static pressure is definitely showing its worth and it's unfortunate to not know the minimum specs of this fan since Noctua doesn't advertise them. Still though even at 100% this fan is much quieter and because of its awesome cooling it won't need to stay at 100% for very long. So to answer the question... is it worth $30? That's for you to ultimately decide. I'm happy as I can now live in relative peace without the ramping up of a loud fan while also and getting cooler system temperatures. It didn't make as big of an impact on cooling as I would have liked, but that shows the radiator isn't that restrictive. I can also set my fan curve to be a little more aggressive without the obvious added noise. I think this may be the current king of 140mm SP fans, but not without a price.

Was 'pseudo' thermal throttling under full load on my 5950X with the stock Arctic Fans (280mm rad) - I say 'pseudo' because while I wasn't nearing the 90 C limit, my clocks were dropping drastically past 80 C. Now, they stay stable right at 79 C. I originally bought two Chromax fans to make the upgrade (1500 RPM), but ended up getting 4 used in a row...being sold as new through Amazon...be sure to check your stuff. It's clear in 2023, fraud is up, even though prices on things like these fans haven't changed in price. So watch out for that. Pros: - Great airflow, even at low RPM. Comparable in noise to the standard brown NF-A14 at lower speeds. - Noise generated is not fan motor noise, it's the noise of air whooshing Cons: - The fan's cable is super long and management can be a pain. Noctua has it right with the NF-A14 Chromax - those fans have a stub where you can choose to attach your own extension, or plug directly into an AIO without lots of excess cable, all right at the fan. I wish this was the standard on all of their fans, not just the Chromax line. - Airflow is noisy at higher RPM's, similar to that of a slim/quiet bathroom exhaust fan Opinion: Anyhow, after I returned all four Chromax fans, I debated whether to jump for the 2000 or the 3000 iPPPC. I think the 3000 iPPPC would be the best fan to get if you don't mind the noise of a tiny jet engine; however, some people are saying to just adjust your fan curves to account for that noise; only let them hit 3000 RPM when absolutely necessary. While that may be an acceptable venture for some, I think the motor in the 3000 is still louder than the 2000 at the same RPM. Plus, you should consider the diminishing returns on that extra 1000 RPM: noise being the biggest one and power draw being the second. Sure, there is an additional 2.4 mm H2O gained from the 2000 to the 3000 iPPC. And sure, the 3000 is going to move more air; but I think at those numbers of airflow and pressure, the limit of cooling is the thermal capacity of the radiator and not necessarily how fast the radiator's fins can be cooled. I think if you're in the market for fans that 'get the job done' on an radiator (AIO or otherwise), you'd probably do best to get the fan that most closely scales to the size of the radiator. For example: Standard NF-A14 (1500 RPM) on a 420mm radiator Industrial NF-A14 iPPC (2000 RPM) on a 280mm radiator Industrial NF-A14 iPPC (3000) on a 140mm radiator On a 280mm radiator, the 2000 iPPC is just fine. I think even the Chromax or the standard NF-A14 would be fine, depending on your CPU. Of course, it's just an opinion.

I know other reviews will mention the sound but do know they are fairly loud. These are industrial fans no louder than rack mounted pc fans but considerably louder than traditional case fans. You have been warned. My AIO died which prompted me to swap to an air cooler and upgrade fans. A year ago I upgraded to Noctua Chromax fans trying to limp my AIO along but once it finally died I opted to replace my intake and exhaust fans to 140mm fans but didn’t want the regular 1700rpm Noctua Chromax 140mm fans. I am now using a Thermalright Phantom Spirit Evo w/ 2 120mm Chromax fans in place of Thermalrights fans on the cooler itself and now 2 140mm Noctua 140mm 2000rpm intake and exhaust fans in a Thermaltake Tower 100 ITX case. With the new cooler and 120mm Chromax fans I was hanging at 48c idle. After the 140mm case fans idle was 42c and 85c at 70% running Cinebench. So far I have not had them ramp up to a full 100% with a custom fan curve. At full 100% these fans maintained 32c idle and did not test Cinebench to provide a load test though I should have. Might try it later and update this review. I am happy with the results so far they move a noticeable amount more air with an an acceptable amount of noise over the 120mm Chromax. Again just know these are louder fans and might require playing with the fan curve in the device bios. I will update this review later.

6 years later-ish and my Covid build is still blasting with these fans. Can’t believe it’s already been 6 years but they work great to this day

Strongest fan and quietest fan I've ever used. One of these puts out enough air to force air out of every grill in my PC case on full speed. However, on full speed, this thing is pretty damn loud. It's probably tons quieter than any other fan that puts out a ton of air at the same RPM, but just worth noting that if you use this above 40%, it's going to be loud and your "silent" PC won't be silent anymore. With that, if a little noise won't bother you, two of these on a 280mm radiator would rule. They've got excellent flow and a super high static pressure. For the price, there is a Phanteks PWM 140mm fan that won't flow quite as much, but is still impressive with about the same noise profile for about half the cost. Also to note, I'm using this Noctua fan to blow in on the side of my case above my SLI graphics cards. I placed a thermaltake magnetic fan filter over the stock (Fractal Designs Define R5) fan grill and the noise went down considerably. I think it was making a resonance against the case grill which contributed to the loudness.

Fit in a H510 case top mount not too loud but cool my computer greatly

Bought 5 of these for my Corsair 750D case. Love them. Most of the time the 3 I used for the case are off, only the 2 on my H110i GTX are on full time. Those 2 are noticeable, but easily drowned out by music or games. At load the fans turn on at what I assume to be their lowest setting which is pretty quiet considering there's 5 of them. If you are looking at Noctua fans you probably already know what these are, but in case you don't, these are basically your top of the line fans. At this stage you are just trying to squeeze out every last bit of cooling performance you can. The upside of spending a bit more on fans is that they last a very long time and can be taken from build to build, so unlike other components you may replace every year or so, fans can stay with you virtually forever. The Noctua's have a 7 year warranty so, take the amount you are paying divided by 7 and that's your max yearly cost for the fan. So I got these for use with my Corsair H110i GTX. They were LOUD, even with Corsair link set to run them at 25%, they were still very loud. But I noticed the RPM reading on them was always around 1900-2000 RPM. I don't know why, but when hooked to the Corsair controller they always ran at max RPM. I put them on my motherboard headers instead and configured the pump to always run at max speed. Now in silent mode at idle they run between 0-500RPM. Basically it just bursts them every few seconds to get them to move a little air over the rad. They are truly silent now, you could hear a pin drop over these fans.

Ich habe die Lüfter für mein PC gekauft, weil die originale Lüfter von Corsair waren sehr zwar sehr leise, aber hatten kein Power. Die neuer Lüfter sind auf dem voll Power ist laut. Unter 1000 Umdrehungen ist der kaum hörbar und bittet trotzdem genügend Leistung. Verarbeitung ist sehr gut und der macht kaum Vibrationen. Also ich kann das Produkt nur weiter empfehlen. Einkauf lief wie gewohnt problemlos und Lieferung war schneller als ich es erwartet hatte. Ich bin begeistert von dem Produkt und dem Verkäufer :)

Los mejores y más silenciosos

Perhaps I have low standards, but I thought this thing was going to be way more obnoxious than it is. I have the 2000 rpm model and below about 90% speed it produces what I would describe as acceptable 24/7 noise. Even 100% would be fine by me with headphones on while gaming, though it's not necessary. I bought this to go with a normal 1500 rpm Noctua 140mm redux (the gray one) that I've had for a number of years as those were out of stock, and I am satisfied. It's a little more expensive than those gray ones but otherwise seems to essentially be just a better built version of those as far as I'm concerned that can be turned up a little more if ya want. Have the mismatched pair as intakes on my case and they move a lot of air for little fans. All that being said, I am used to computers making noise. If you are used to a silent computer you will not be happy, but you probably aren't looking at industrial 2000 rpm fans if you want complete silence. If you are fine with some audible though not obnoxious fan noise, these are pretty great and move a lot of air with supposedly decent static pressure. Tempted to get a couple of the 120mm version for my NH-U12S now that I know they're not obnoxiously loud.

I only use Noctua fans, and these have an annoying whining nosie, im just waiting for NF 140mm G2 chromax fan to replace these ones i have

These are excellent fans in terms of RPM range and static pressure. They are also relatively quiet at higher RPMs, up to 2000, compared with other fans - yes anything spinning that fast will be noisy, but these are quieter than the stock Corsair SP140L fans on my H115i radiator. They are also more efficient at higher RPMs thanks to the 3 phase motor technology. However, at lower RPMs there is a constant noise coming from the 3 phase motor, which is louder than the air movement sound. It is on par with the constant high pitched hum that I get from my H115i pump on the CPU, which is equally annoying if you are at all close to your computer. The noise from the PPCs is more like a grinding/churning noise, which disappears at higher RPMs but then is replaced by noise from air movement, so the fans are never really silent. The 3 phase motors might be better suited to a noiser fan overall than fitting them on a high SP silent fan. Reviews are mixed on these fans as to whether they are noisy or not, and ppl's verdicts are subjective, as some ppl have their computers under the desk and/or are more 'laid back' and don't really notice finer background noise whilst others are more detail oriented or OCD and it drives them nuts. Whilst a youtube review showed these PPC fans matching the low noise of the ordinary NF-A14s at equivalent RPMs, I asked Noctua themselves and they said that the PPC fans were noisier at lower RPMs, from 800 to 1200 but otherwise the performance at equivalent RPMs was identical. The RPM range of the standard fans starts from a lower value, at the same voltage, and you will get lower RPMs from the standard fans compared to the PPCs if you don't use a voltage stepper of some kind to lower the voltage of the PPC fans. Lower RPM = quieter obviously anyway, without the constant churning noise. I chanced it from the reviews and regretted it and sent them back and am now using NF-A14 chromax instead (I hate brown fans lol they are hideous). So overall, these are great fans, but just not suited to a rig that is really meant to be quiet.
