Noctua 140mm NF-A14 PWM 1500RPM Fan

There are many Case fans available, some with higher CFM (airflow), some with higher Static Pressure (Air Pressure) but this fan is the All In One package. Of all the fans that have high CFM, they have low SP and all the higher SP fans have lower CFM. So what that means is a high CFM fan will spin fast blowing a lot of air but a slight draft or any resistance of your case and the speed of the fan drop dramatically, so in the end, low airflow (CFM). Static Pressure gives strength and force to the fan but without higher CFM, it doesnt move enough air to be effective.These Industrial fans are very much both all in one. When this fan blows, you can feel the blast of air and case resistance, overhead fans, gusts of wind etc do not affect or slow it down.

When this fan blows, you can feel the blast of air and case resistance, overhead fans, gusts of wind etc do not affect or slow it down. To effectively match the 3000 RPM fan, you would need at least 3 high CFM and 3 High SP fans all daisy chained together. 6 x Expensive high end fans to match 1 x 3000 RPM Industrial Fan. Very cost effective and only takes up 1 case fan slot. IMO the 3000 RPM is perfect for a rear exhaust fan, blasting the hot air coming off your GPU out the back keeps the internals of the case nice and cool. Especially good if you have a AIO water cooler radiator on the top as an exhaust, you don't want the GPU heat being pushed through it.As for noise, yes it can get a little noisy. If you remember old CD drives, it can sound like them when they speed up to read the disk. Its audible but not that bad. The actual audible sound usually only can be heard when it reaches 75% power, which if tied into your Motherboard or other fan controllers using a default heating power curve, the fan usually stays under 75% unless your cooking your CPU somehow. Still even under 75% power the force and flow of air is quiet strong. I can confirm the 3000 RPM model DOES NOT work Corsair Commander/XT/Pro but the 2000 RPM model DOES. The 3000 RPM model has a slightly different PWM Controller that for some reason Corsair doesn't like. I found no other conflicts so connecting to MB or other software etc is no problem. Also the 3000 RPM model uses 6.6 watts, with most motherboards having only 12 watt fan headers, you wont be able to use a fan Y splitter. Check you Motherboard manual before you purchase. Usually higher end MB's have 24 watt headers but just check to be sure.The 2000 RPM model is powerful in its own right too so don't dismiss it because its not as fast, because there is still a lot of power and force. Just FYI for those that don't know. The difference between the IP52 and IP67 model is that the IP67 models and much more dust and water resistant so if your computer is in a high dust or humidity environment then the IP67 might be a better option, not that the IP52 will choke because after all it is an industrial model. Just choose based on the environment you have but if its really bad, go the IP67.In summary, you really can't go that wrong with the Industrial Fans, sure they can get a little noisy, but only when its so hot that you need some serious cooling. Sure the other fans might be quieter at full speed but they could never keep up with the performance of these fans and when you don't even need that performance, you can't hear them anyway. With these fans providing cooling, you probably won't even get high temps but if they do make noise, its the same as a disk drive loading volume, that's all.

Amazing fans at a great price, work great on a liquid cooler

I bought 2 of these fans to replace the stock fans on my Corsair H115i as they were loud and annoying.I put these 2 fans on there as I used to have a Noctua cooler back in the day and that was quality. These fans have made my PC much quieter and the cooler works just as well if not better than with the stock fans.These fans would work amazing as replacements for either case fans or cooler fans. all round amazing fans.

Better than my high expectations

Quality:Using 2 of these pulling as an intake through a corsair H110 (the original fans had that horrible bearing rattle they are known for). These are very impressive, people have written at length on the internet about noctua quality, and I now understand why, very high build quality, solid, those rubberised corners seem to work very well, and the braiding on the cable is rubberised which is really nice to work with. Even the packaging is nice.Noise:2000rpm is gonna be audible no matter how you do it. I find the noise from these at full tilt more tollerable than any other fan I have used yet. You can hear the motor, but I had some xigmateks years ago that went up to 1100 and they had horible phase noise from the motors. Put it this way, I was watching snooker ... MoreQuality:Using 2 of these pulling as an intake through a corsair H110 (the original fans had that horrible bearing rattle they are known for).

Put it this way, I was watching snooker while they were at full speed.Performance:I'm using these in pull mode as a top intake through the 240mm radiator of the H110 I mentioned earlier, hooked up to an FX9590, 220watt TDP, about the same as a highly clocked intel I5 (so I hear).In push almost no air will get through the radiator, because they move so much air at a high pressure it buffets on the radiator fins and becomes turbulent (you get lots of noise and little heat exchange). That aside, I managed to hit 75 degrees C (and inevitable shutdown) using stock fans in pull mode after 20mins of Prime95. Put these on, same configuration, reached 58 degrees after 20 mins, 59 degrees after 45 mins. Nice to know they have the extra cooling ability if needed.It is in Idle to medium load situations where these fans show how good they really are. They flow so much air through a radiator at medium to low speeds that they can run ~200-300RPM slower than the stock fans. Might not sound much but the difference between 1000rpm and 1200rpm is pretty audible. I can hear my mechanical hard drive over them. Its not silent, but having the window open is louder...In conclusion, worth every penny. Perfom as well as I had expected, given the price. (and they arent the usual noctua brown!)

Great high power fan with low noise

Really love these fans, replaced stock case fans with this and really happy with that choice. Noticeably quieter than the case fans, and act as the 3 main intake and 1 main exhaust, no complains. Running them on a very low fan curve for day to day tasks and only ramp up when gaming - super quiet idle.

It is exactly what it says!

The fan is very powerful, moves quite a lot of air. I was really surprised but on the other hand, it is noisy and no one tried to hide that fact.If you put it on rad then the noise is still bearable and muted some how up to 60 or 70 percent but it's still a jet above 80.Do not even think about using it as a case fan!! Even at 40 percent the sound is very distracting.However if you want to move a ton of air or if your box is located in another room then ofcourse this is the best fan you can buy imho.

Premium fans live up to their name

I bought these to help quiet down a very beefy build I put together. Using a 9900k with a 280mm radiator, I replaced both the radiator fans and 3 more case fans with this model. When I first turned my PC on after swapping the fans out, I thought I broke it or unplugged something because I heard NOTHING. Then my monitor turned on and I realized that the fans were just THAT quiet. I use vmware workstation pro and run approximately 20 virtual machines, and the fans are still barely audible under that load. They do a great job of pushing enough air through the unit, and remain so quiet I have to take my headphones off to hear them under load. When you take these out of the packaging, they feel heavy in your hands. It's very easy to tell how high quality these are, and ... MoreI bought these to help quiet down a very beefy build I put together.

Unfortunately I think the one downside is, I'll have to buy a set of these for every new build going forward.

Quality through and through

I have two of these as intakes in the front of my case. These things scream quality … the weight, the rotation, the lack of any play in the fan, the materials – all top notch. I can see why Noctua confidently offers a 6 year warranty. I use a case fan controller which offers 12, 7 and 5 volts. Without the LNA, and the fans at max 12v (1500rpm), they are definitely audible, even through a noise dampened Desxxgn R4 case. The sound isn’t obnoxious at all, just a distinctly audible wind rush sound. However at that 1500rpm they push a crazy amount of air! I have mine on the LNA and my case controller @ 12v – so they run at a constant 1300 rpm, and are dead silent at that setting. I find that speed to be the perfect noise \ airflow ratio, and they cool my stacked HDD’s v. ... MoreI have two of these as intakes in the front of my case.

They’ve dropped temps a few degrees with a more silent operation than my previous 140mm fans up front. Other fans may offer equal airflow or sound levels? Not sure ... but for me the selling point on these is that they deliver the goods with the additional piece of mind that exceptional build quality and a 6 year warranty bring. Check ‘em once and close the case. See ya in 6 years! I have no problem shelling out a few extra bucks for that and am very happy with these fans. I’m sure I’ll buy more in the future.

Silent and highly effective

I bought these fans for all of our full tower workstation PCs; specifically our workstations use Corsair’s Obsidian 750D series cases. These 140mm fans are perfect replacements for the ones the case came pre-installed with. The original 140mm front panel fans are not very effective and run poorly. Although our workstation cases themselves are equipped with a solid front panel block, which can hamper the fans’ full benefits, our business environment is openly prone to dust, powders, metal and wood-chip shavings. It is necessary for us to preserve the longevity of our internal hardware as best as we can. Having these fans in the system front panel made a significant difference in airflow purely from the sheer amount of air it puts out.

These fans blow!

I have a Corsair 450D and attempted to replace the two front case fans with this model from Noctua. I thought 'industrial' was referring to it's reliability. No, they are referring to super-high spin rates to move industrial amounts of air! The Noctua NF-A14 is the fan I needed. It's $6 cheaper, includes rubber anti-vibration mounts, an extension cable (fan cable is very short), a splitter and a low-noise adapter (which runs the fan at a fixed speed of 1200rpm or to cap the maximum speed when using automatic PWM control.) Furthermore, when I removed the long machine screws that hold in the front case fans of my Corsair 450D, they proved to be too short for mounting these Noctua fans. I had to use the extra fan screws from my Kraken x62 AIO liquid cooler. Once again, ... MoreI have a Corsair 450D and attempted to replace the two front case fans with this model from Noctua.

No idea who Noctua is making these for, but it sure would be nice to have an entirely different name brand for them. Differentiating one Noctua fan from another is getting more complicated than it should be. So, watch out for that little 'i' in Noctua's naming scheme. The 'i' stands for INDUSTRIAL!
