NF-A14 iPPC-3000 PWM, Heavy Duty Cooling Fan, 4-Pin, 3000 RPM (140mm, Black)

Previously, I had an NF-P14 that was pulling double-duty in the middle of my old NH-D14 heatsink (the other fan that was originally with it currently resides in the case's exhaust slot directly aft of the heatsink). This setup worked fine during winter months, but in recent weeks has resulted in intermittent overheating due to the warmth of the room. Rather than restore the heatsink's stock configuration, I opted to simply beef up the heatsink's fan and move the NF-P14 to the case front to supply it; I'd been intending to replace the low-end Cooler Master fan I had there anyway. As both high airflow and high static pressure were needed...this fan was a bit of a no-brainer, even if it is pricy. First off: if you too have an NH-D14, rest assured that this fan will fit. It won't fit as intended (the original mount kit was designed for 120mm-mount fans, the NF-A14 has 140mm mounts), but the heatsink is wide enough to support the fan, and you'll have a bottom overhang for RAM/VRM/etc cooling as with the original NF-P14. Just make sure that there aren't any components extruding from the board that will interfere with the corners. See attached pictures for my super-exotic mounting method. Secondly: despite Noctua's best efforts, this fan is definitely not quiet at higher speeds. Even throttled at 50%, it's quite noticeable, though it's not unbearable. At 100% (which comes to ~2750rpm on my board...something I find slightly worrying actually), as noted in other reviews, it sounds akin to a small vacuum cleaner. If you plan to run it in a gaming PC, make sure you figure out what speed you need for adequate cooling, and stick to that under load. Look up your CPU to find its maximum safe temperature, and set your fan curve to have it kick up to 100% ~5 degrees before that. The fan has PWM control for a reason...use it! There's no reason to deafen yourself under light or no load. Noctua's site lists the minimum speed as 800rpm, however, my board's minimum PWM setting is able to run it at ~400rpm. I wasn't able to test at what point it becomes "silent", but it certainly is at the lower end. I'd expect it to be no louder than the NF-P14 up to 1300rpm, and I never had a problem with that fan's noise. Finally...it's a solid fan. Noctua, in my experience, makes high-quality stuff; this fan is no exception. The price of it made me handle it carefully, but it didn't feel fragile at all. Even the blades, thin as they are, feel solid...I would recommend not putting your fingers anywhere near them while the fan is running. The box is quite nice, but what you actually get is just barely above OEM-level; the fan and wide-thread screws for plastic fans, nothing more. I imagine that the common user would be disappointed by lack of low-noise adapter and/or splitter, but consider: the fan is PWM (a control method far superior to resistive/voltage-based control), and is rated for more than half an amp at full load. It seems to be commonly accepted that motherboard headers shouldn't be loaded above 1 amp, which would be easily exceeded by pairing two of these at full speed on a single header. I would guess that the cost of including a splitter in every box is a drop in the bucket for Noctua, but they chose to not include one to protect themselves if users decided to overload motherboard headers and potentially burn them out. They can't be held responsible if the user finds a splitter elsewhere and decides to risk it, after all. In summary, It's an expensive fan, costing as much as an 8gb stick of DDR3. But for the price you get a fan that performs well and quietly for day to day use, and unlike Noctua's consumer-grade offerings, can go full-out balls-to-the-wall if high levels of static pressure and airflow are needed. It can be made to fit an NH-D14 with the mildest of adaptation, and (according to reviews and Noctua specs) will directly fit an NH-D15. The included accessories are...well, non-existent, but with a proper setup you won't need them anyway.

I love these fans! I was hesitant to order them because of some reviewers saying they're horribly loud and others saying they were quiet. I was willing to take the risk and bet on the fact that those complaining they were too loud just didn't take any time to configure them, and I am so glad I did! I installed 4 of these 140mm fans and 3 120mm in my new rig and I absolutely love them. I have 2 140's as front intake, a 140 as rear exhaust, a 140 as bottom intake next to PSU, 2 120's on my H100i radiator and a third 120 next to the radiator as exhaust. They all come with rubber brackets and I installed all but the radiator fans with Cosmos rubber rivets. Super easy! They all come with rubber sleeved cables that aren't too short and aren't too long. I did have to run a y-splitter for my two front fans because I ran out of pins on my motherboard, and it was enough of an extension to help them make it across the huge case to get them plugged in. If you have a large case and intend to put these near the front of your chassis, you will most definitely need extensions so plan ahead! I'd rather have to extend one set of fans than have 7 fans with super long cables cluttering things up. After the quick and easy installation, I powered everything on and I was shocked at how loud it was. It was loud enough that my 10 year old and I had to raise our voices to hear each other clearly when sitting 4-5 feet away. HOWEVER, using ASUS' UEFI on the Maximus VII Hero motherboard, I was able to use the built in Qfan to quiet them down enough to the point that I could tolerate sitting near it while I installed the OS. Once Windows was installed, I installed AI Suite (included with my motherboard, you may need to locate another fan controller if you don't have an ASUS board) and went into fan setup. It has 4 predefined modes to choose from with further customization possible if desired. Silent mode literally turns off all fans except the CPU fan, which it turns down considerably and the entire rig is dead quiet. Standard mode is a step up but still extremely quiet, even when sitting only 2-3 feet away. When on the other side of the room playing games on the TV, I don't hear it at all. The other two settings include turbo (around 1500 rpm) and full power. When all fans are running at top speed (about 2700-2800 rpm), it is extremely loud. Turbo is tolerable. The sweet spot is around 900rpm, which is enough to keep an EVGA GTX 980 Ti under 60 degrees while gaming and keeps my i7-4790k under 40 degrees, even under load. The result is a very stable, quiet and cool rig. I haven't found anything that can cause this system to break a sweat and I attribute it largely to these fans. I am so very pleased with these fans, I can't say enough good things about them. They are roughly twice as expensive as other popular fans, but I'd much rather take the cool, quiet performance of Noctua fans than have fancy loud LED fans in my rig. I'll definitely be picking up more Noctua's when I build my husband's rig next month.

These are high quality fans! You are going to need to be able to regulate their speed. Right now mine are attached to the MB header and their speed is temperature regulated. At lower speeds they move a good amount of air and are silent. The fan in my PSU is louder. During video transcoding they rev up and sound like a pair of small blowers. They keep my water loop at 40c or less. These aren't bling'd out, but they are solid and work well. If you want lights get a couple of RGB light strips and don't worry about putting lights on your fans. Bought 2 more. When I start my PC before the BIOS gets to the point that it begins to regulate the fan speed it sounds like my PC is going to achieve "lift-off." When I'm gaming and need their air circulation these fan step-up. Nice thing is when I'm gaming I don't notice the extra noise from the fans because of the noise from the game. Other fans are quieter because they don't have the head room to move the kind of air these fans move. These fans are just as quiet until you need the air. These fans are designed to be silent when you want silence and move a ton of air when you need the air.

This fan is extremely powerful. Compared to normal computer fans, you can feel a much greater airflow. It seems to have worked quite well with cooling my PC, I'm able to run it at a higher speed without it overheating now. I can feel a significant amount of air moving through the case. That said, it is loud. The manufacturer doesn't pretend this is a silent fan, and it is supposed to be for industrial use. If you are going to use it for a PC in your office or home, get ready for some noise. It has the high pitched type whine of a jet engine, which can be annoying. I personally am not bothered by it, but I am good with shutting out external noises when I am doing something, not everybody is like that. I'm using this fan in a push-pull type configuration with a water cooling radiator on my PC, and it is working quite nicely. So, if you need extensive cooling power, this fan is it. If it's an industrial environment where additional noise is not an issue, this is definitely a good fan. If you are in an environment like an office or home where a noisy fan will cause a problem, DO NOT buy this. As with all Noctua fans, this fan is very high quality. I like the material it is made out of. At first, I hated the coloring of Noctua's fans, but they kind of grow on you. What is good about their design is the mounts absorb the vibration of the fans, which eliminates what I consider the most annoying noise of a fan - rattling against the computer case. UPDATE: The fan is way too loud for my family, and they are always complaining (my office is at home). Also, it is distracting during online meetings, and is a problem when I try to do videos. I just disconnected them and am replacing them with quieter fans. The product is great, but the sound can be very distracting. If I was still in an office, I think the sound would also drive my co-workers insane too.

First off, let me emphasize if you're looking for a dead silent fan, this fan is not for you. Having said that, it offers phenomenal performance as a cooling solution for the Corsair Carbide Air 540 case and the Noctua NU-14S CPU Cooler. I bought six of these to replace the three stock fans in the case for my Hackintosh, add two more more in the top, and replace the NU-14S stock fan as well. Running all six on the bios "silent" mode setting @ ~1100 rpms brought temps down 7-9 degrees Celsius at idle for the 8086k CPU cores and 7 degrees Celsius for the Radeon VII GPU. Everything now runs at 21 to 25 degrees Celsius at idle and while checking email, web browsing, etc.... Yes, they're audible at 1100 rpms in the case sitting 3 feet away at desk height, generating a moderate *whirring* sound, but the cooling benefit far outweighs the temporary distraction that I no longer notice, and the comfort of knowing these fans will keep temps down at 100% CPU utilization while encoding for long stretches. When they ramp up during encoding, they get louder but not obscenely loud and it's tolerable for me. I could drop them to ~ 800 rpms as the minimum and eliminate the sound, but 1100 rpms is fine. I'm also using seven of these fans - in an identical case - in a customized dual Epyc 7702 setup (128 cores, 1.2TB memory) and again, performance is stellar. Encoding at an all core turbo of 3.35GHz for extended periods - 100% CPU utilization - the CPU cores never rising above 49 Celsius during that as well as stress testing. I believe that speaks to the quality of these fans. By the way, the comedy of installing an E-ATX Tyan dual EPYC motherboard, dual Noctua NU-14S CPU coolers and seven of these fans in a Carbide Air 540 is worthy of a tech site video (note - the two 140mm front fans have to be mounted on the outside under the front cover). Bottom line: If you want the best cooling fan available to the consumer market and don't mind some fan sound, buy this fan!

These fans are by far the loudest fans I have ever used. Anyone who says they are quiet is deliberately capping the RPM in the BIOS. These are meant to be high airflow/high static pressure, and they are very good at that. They also have a bearing whine at low RPM because of the design. Above 25% speed they can be heard through noise cancelling headphones. If you are not going for the absolute maximum airflow possible, you should look for a different fan. These are overkill for any gaming PC. This is coming from someone with a heater of a system with a 5090 and 9800x3d. I'll personally be replacing them because they are substantially louder than I expected and produce way more airflow than I would ever need even when pushing the system. These however would work wonders for a server rack or something that needs a lot of static pressure and isn't going to operate in a room with a person in it.

Even though they're about as loud as a leaf blower (yeah, that's a tiny exaggeration), yes, they are loud when on high speed. But I have been using these fans for a few years now, and when they normally sell on their website for $54 a fan, I was like, how could I pass up this deal at $32? Also, they are hard to find because they are always sold out. So when I saw these here, I just knew I had to get them as fast as possible, even though I don't need them right now, and I always like to have some backup for my other seven fans in total just in case one or two goes out. I will have my favorite fans at my disposal. These are some great fans. They perform well. They might be expensive, but they can put out some leaf blower air, enough to blow your hair back. These are very, very highly recommended.

This is an environmentally hardened high-performance fan. At 0% PWM, the fan stops. At around 10%, it spools up audibly with the only time I've heard motor noise from it, then rolls back to ~500RPM. My specific fan can run as slow as 400RPM indicated, but this will vary with manufacturing tolerance. It has the same physical design as a normal Noctua NF-A14 fan, so up to about 50% PWM, it has the same noise profile as said fan from 0-100%, except for the slight motor noise when starting up from 0%. Bear that in mind if you want to run it in a semi-passive build. Then it KEEPS. GOING. At full power, this thing is far from silent, but who expected a 3,000 RPM fan to be silent? That said the sound profile is not objectionable, and I honestly found it fairly pleasant up to about 75%. The motor is basically silent, any noise drowned out by rushing air and blade turbulence. The blade noise starts getting a little shrill above 80% PWM, but if you really need that much air moved, I think noise is the last of your problems. I haven't owned the fan nearly long enough to comment on its durability and ruggedized design, but "a computer case fan" is hardly a challenge for this absolute unit of a fan. It'll probably outlast my computer. - My original plan was to use this as my computer's intake fan, and two 120's as radiator cooling fans. My plans changed, but I'm sure I'll still find a use for this thing. - Don't get your fingers caught in it. The motor's direct power isn't awe-inspiring, but at full RPM it's definitely carrying enough inertia to do some real damage. Consider a fan grille if anything might touch it while it's running, whether cables or fingers.
