Noctua NF-A12x25 PWM, Premium Quiet Fan, 4-Pin (120mm, Brown)

These fans are excellent quality—so glad I purchased these. Replaced my default dell fans and these noctuas just really push as much airflow at less rpm and less noise—exactly what I wanted.

I really want to recommend these fans, cause they are so quiet, and they cool my pc so SO effectivly and efficently with the perfomace just being outstanding and the color leaves such an accident that I love personally and its SO SO easy to install with the cable extentions HOWEVER, they are so expensive compared to buying some other coolers for packs of 5 and 3x less the price. Id only reccomend this if your planning on running a crazy ahh build like me, or if you just want a real quiet pc. My only flaw with the the product isnt really the fans, but the extensions that it comes with, they suck. They work for that they are suppost to do, but the damn thing is so short and hard to bend that it kinda defeats the purpose. Besides that, for me, a little expensive, but so worth it

I just built my screaming Ryzen9 beast of a PC with a dual 120mm Corsair AIO. I foolishly figured I could cool the volcano that is Ryzen9 with minimal noise on a dual radiator. Not only could I still hear a slight whooosh from the stock Corsair fans at their lowest controllable PWM speed, but the CPU temps floated at 47-52C idle. I tuned up my fan curves to keep things relatively quiet, but anything over 400rpm on the stock fans was audible. Worse yet, when I blasted the CPU with some full load tests, the case damn near took off and flew out of the room. Temps settled at a max 72C, but the fan noise was punishing. It is rare that I will ever get a full 24core load like that, but... I still have to know the limits of my system, right? Annoyed... I hit Youtube. Linus always uses Noctua fans and I kind of figured that was just product placement, not really performance based. How much better could Noctua fans really be...? The Amazon reviews just seemed like an exercise in cognitive bias: "Well I paid $100 to swap all my fans to Noctua, so they must be better... duh!" I've been building PCs for 20 years and I have always tried to stay away from 120mm fans in favor of larger 140mm (or even 200mm when my cases allowed). Bigger fan = slower speed & less noise for the same amount of air. At least, so I thought...I swapped the two front 120mm fans on the AIO for these glorious NF-A12's and I was shocked at the difference. SHOCKED I TELL YOU! Before I modified any of my fan curves, I noticed the idle temp average dropped about 2C--no tuning changes, just the new fans. However, that was running the AIO fans in the 400RPM range. I played with the PWM and discovered that anything under 1000RPM these A12's are pretty much inaudible. Therefore, I picked my idle setting up to ~800RPM. I can't hear a damn thing sitting at my desk, BUT... my idle temps are down to 38-42C. All I hear is the gentle whine of the AIO pump on its lowest setting. Seriously, its absolutely amazing how quiet these fans are. I honestly got down on my hands and knees to figure out if the fans were even spinning! Not until I had my ear 6" from the case could I hear anything. Fantastic. I swapped my top exhaust fan for a NF-F12, which is also pretty quiet, but I wish I had spent the extra $10 for another A12. This is not only because the A12's are even quieter, but their minimum PWM setting seems to be closer to 20% and I can't seem to control the F12's with less than 36%. For me this is fine because at anything below 50%, the F12 is also basically inaudible. However, if I was trying to truly build a ZERO noise box, I would want the lowest minimum duty cycle possible on the fans. The short story is this... I am a full Noctua convert now. I will NEVER build a PC with anything but A12's--until Noctua comes out will something better! I hate the color, but love the performance. I was really considering dropping down to a Ryzen7 just because I didn't like the high idle temps I got with fans tuned down to a tolerable whine, but not anymore! Quieter rig and 8C lower idle temps? Yes please! These fans are so worth the $30 each, it sickens me.

I've been using Noctua fans for years in my PC builds. I just upgraded from my old i7-6700K to a Ryzen 3900X, and with the all-core overclocking and a 2080 Super FTW3 I needed some extra cooling in the case and for the CPU. With the standard 3 120mm fans on a NZXT Kraken X72, CPU temps at 4.2GHz/1.2v VCore were way up in the 97C range using the default fan profile. Ramping that up to a higher speed brought temps down to ~93C under Prime95 "Blend" torture tests, I'm not usually happy until it sits in the 60s or 70s. My radiator is mounted in an exhaust position at the top of a Thermaltake Core V71 case with two Noctua 140mm 3000RPM fans as intake in the front and another one in the usual rear exhaust location. With the 140mms running around 600rpm and the default NZXTs wide open, I just could not get it down out of the 90s under load. I replaced the three NZXT fans with 6 of these NF-A12x25 fans and the 3900X will not get above 73C for ~15 minutes with the fans at nearly inaudible levels (~900 RPM). With the fans set to ramp almost linearly up to 100% (2000RPM) at 80C, I now see a max temp of about 83C with the GPU at 100% load with MSI Kombustor, and about 77C with the GPU at idle. It's just not even the same setup anymore. Granted, it needs a fan header hub to support all those fans but the MSI MEG X570 ACE does a great job at controlling all the speeds and keeping things very reasonable now. I had some original NF-A12 fans that were doing OK, but the newer A12x25 blade design appears to have a marked improvement over the previous simple straight-bladed design. These are expensive, but you also don't need as many fans as I use to achieve a significant reduction in noise from your PC. And they work for the case, air and AIO water coolers, etc. Just love these things.

I ordered 8 fans for my PC to switch out my old fans in my 2019 self-built, budget PC. All fans were replaced. The exhaust and intake, and for my new CPU air cooler (not noctua), the stock fans were replaced with these. After much research, the NF-F12 (pressure oriented) and NF-S12A (heavily airflow oriented/very low pressure), looked to be quite a sacrifice in performance over minimal price difference. AKA, the price:performance ratio wasn't worth it for me when it wasn't far from an A12x25 PWM. Spending $260 for some fans was painful, I'll admit. But when the mean time to failure rate for these fans is 150,000 hours or 17.1232877 *YEARS*, and their warranty is 6 years, my investment was made (felt) easier! First off: Noise Right before these fans, I had the redux fans installed (NF-P12 redux-1700 PWM) as my 3 - 120mm intake ones for about 2 weeks, before returning them for these A12x25 fans. And man, they were LOUD. Most of the games I play really heat up my PC (Flight sim, Star Citizen, Apex Legends), therefore my fans are often spinning on the upper side of their RPM range. These A12x25 fans at high speeds can be loud, but they have a nice white noise with acoustics that sound like they were thoughtfully engineered. Honestly, anything above 1500 RPM is noticeable. Going into this brand of fans, I had expectations wayyy too high and expected them to never make a single sound. This is definitely achievable with limiting their speeds or getting fans with ultra low noise, but that starts to cost your cooling performance. Good news though! When my PC is idling, I actually have the opposite problem where the fans are so quiet that my refrigerator hum is no longer opposed and is singlehandedly driving me crazy with its "weeerrrrrrrrrrrrrrrr". Performance: Genuinely noticeable. Both with temp sensor reading and especially holding my hand over the exhaust fans. Again, in my previous set up had budget Arctic fans and had an AIO cooler. Now, I have all A12x25 fans and a Thermalright Phantom Spirit 120SE heatsink. My temperatures on my CPU as well as my overall GPU temps have gone down a lot. Like by 10C or more. Even on my CPU when I used the stock cooler fans on the Thermalright vs noctua fans, noticeable difference in temperature and noise there. The performance to noise ratio is phenomenal, with some games like Minecraft, GTA V, and a couple other low power games, performing well without any fan noise! Price: You get what you pay for in life. And with this fan, you DEFINITELY get what you paid for. That price is an excellent representation of its worth. I just hate myself that I justified a $33 price point per fan, but I am so happy. Quality: Fans are heavy and feel like they were built carefully and beautifully. They come with a LARGE selection of addons included in the packaging like rubber "Screws", metal screws, pre-installed anti vibration pads around each corner, even an extra anti vibration sleeve to even further decrease vibration, a y-cable, extension cable, and low noise adapter supplies. All this included in a fancy package, with more packaging information then you could ever want to learn about with the fans. I don't know how I feel about having so many attachments, as I only used 2 y-cable and 2 extension cords. Which leaves me with about 36 unused accessories total. Which I will obviously not throw away, but doubt I will use any more for many many years to come. So I am torn on that large surplus of accessories but at least you get more than you need, rather than needing more than you have. Having 8 fan packages open on your floor will definitely require some space, so be tidy when you open them to prevent having a large organizational mess. Overall: This fan came out on May 2, 2018, and has yet to be superseded by a better Noctua fan nor any other brand. I sincerely doubt that an upgraded version will be substantially better in the near future. Just like with video game graphics, they are already fantastic and it takes a lot to improve it just a little. I feel like it may be the same with aerodynamics and fans. In the end, this investment is worthwhile and will last you for possibly decades with a performance that will be unlikely exponentially bested in the fan's lifetime. Do yourself a favor and start upgrading your PC fans. Start with intake first, then exhaust. Then consider your cooling systems too, but as they have the least amount of fans that make noise, I suggest starting with your case fans first in my personal opinion. The only regret you'll have is that you didn't buy these fans first.

I bought these with the sole intention to see what all the noctua hype was about and did not plan to keep them since i wasn't a huge fan of the color scheme. Once i tried them out, there was no way i was returning them. Everything about these fans is of the upmost quality. It starts with the packaging; you're greeted with a premium box that shows all the spec and details about the fan and how its intended to be used. Once you take the fan out of the box, you'll notice that Noctua goes above and beyond with providing everything one would need with the fan. They include a y-splitter cable, low noise adapter and PWM extension cables in addition to the rubber quick connect pins and noise reducing gasket. Then, when you look closer at the actual fan, you see what has to be one of the best built fans ever made. There is an incredibly tight clearance between the blades and the frame - tighter than i thought was possible since the blades typically expand at full speed. There is also a smoothness that is hard to put into words when i gave it the first flick to see how they spin. Its really difficult to explain the quality any further since it is, at least in my experience, truly the best case fan ive ever seen or used. I am now looking for a new case for my pc where these will look good in since i do not like the aesthetic of these brown fans in my white build.

Update 04-14-2019: The circumstances of my build have changed. I have converted out to an open loop with (2) 480mm x 60mm radiators and in pull only configuration I use the NF-A12x25 PWM fans to handle to air movement. I have two more NF-a12x25 fans as separate exhaust and @ 900rpm on my loop, my 2700x and 2080 Ti are silently cooled. These fans are truly amazing in noise for flow with these thick 60mm radiators, particularly in the 700rpm-1,300rpm range. I can barely hear all 10 of them from 3 feet away @1,200rpm but at 900 they are truly inaudbile and keep the 2080Ti @ 2,115MHz and 43°C in any load indefinitely. For applications where the lowest possible noise for air moved through radiators is required or desired, look no further. I couldn't stand the AIO pump noise from the NZXT Kraken x62 on my Ryzen 2700x build. After listening to a couple of other systems with the EVGA CLC280, Corsair H115, and H150 I determined that my ears are just tuned to pick up water pump noise. So the next step was the best air cooling solution I could find: The Noctua NH-D15 SE-AM4. With my case the stock NF-a15 fans for that heatsink assembly wouldn't clear both the ram and the case side panel. Thanks to some reviews for this fan along with Noctua saying it was a compatible match, I decided to try these fans for the heatsink in order to keep the twin fan capability. I also opted to replace my (7) NF-A14 PWM case fans with (6) NF-A12X25 fans. I was intrigued by the development cycle and the promise of excellent low mid-range to high mid-range rpm pressure and flow rate. These fans deliver in a way the fringes of my hopes dared to imagine possible but didn't actually expect to exist. With the NH-D15 SE-AM4 I obtain the same boost clocks with only a 2c penalty in Prime 95 small FFT or Folding@Home CPU work units vs. the NZXT Kraken x62 with push, pull or push/pull NF-A14 fans. Where the kraken required the fans spun up enough to be audible from 3 feet away and on par (by ear) with the AIO pump noise to achieve the reference level of cooling the NF-A12x25s lose 2c at 950rpm: they are not audible without my ear in direct contact with the case. Best of all, I am running the AMD Ryzen 2700x at 4.1ghz all core under Prime 95 or F@h CPU and hitting 66c worst case scenario and the computer is completely silent at the seating position 3 feet away. This is well within temperature guidelines from AMD, at a significant boost over advertised all core boost clocks that is sustainable indefinitely and while having a total CPU and SOC combined 130 watts of power used. The pure silence and the temps at full load wouldn't be possible any other way. I tried. The Sterrox polymer based NF-A12x25 is a triumph in design and execution whose value is priceless and performance is peerless.

I replaced the radiator fan on a new liquid CPU cooler with this fan, and it reduced the noise level significantly. The stock fan that came with the cooler was too noisy for use in my HTPC. This fan cost half as much as the CPU cooler, but what's a guy to do? If you need cool and quiet for your HTPC, this is the fan to get.
