Noctua NF-A12x25 PWM, High-Performance Quiet Fan 120mm | High Airflow and Static Pressure Low Noise 25mm Thick Fan for Coolers/Radiators/Cases, Rich Accessory Kit, 2000rpm PWM

I bought two because I wanted to the best possible way to modify my 1080ti Founders Edition with the Reference Blower design, which was throttling at 85c whilst simultaneously being loud enough to hear from another room. Unacceptable. Bought a Morpheus II and loved the idea I can cool my GPU like its any other CPU, with any fan of choice. I bought the standard Noctua's previously, which is very well made and performed great. The only issue is that it can get loud if you run high revs. But with the low noise adapter, it's nicely quiet but at the cost of thermal performance. The Premium ones cost a lot more, and I can wholeheartedly say the extra price is well worth it in immediate results. They are attached to my GPU, the static air pressure blowing into the heatsink. Mounting required the Y cable which is conveniently given in the box (a REALLY extra nice quality box by the way. It's prestige as hell in presentation, no compromises by Noctua not even for a single fan.) I also thought to use the low noise adapter attaching it to a 4 pina adapter directly to the GPU. The fans max out at 1450rpm with the low noise adapter. So I set the speed at a single 100% because it makes no noise. It is a soothing hum if you tried to hear it. A lovely feeling to benchmark the card at the highest possible settings and no sudden fan ramping up and down, just a whisper-quiet hum. The acoustics are wonderfully developed with a lot of thought into its design. Some fans might be quiet in decibel levels, but they could also hum a tone that might not be particularly pleasant. The Noctua's fan, when you can hear it, it has a sort of acoustical design language that only produces a quiet, somewhat relaxing and soothing hum, like smoothed brown noise but without much low-end frequency, kinda like a summer light breeze as corny as that sounds it's the best way to describe it. This is at maximum speed with low noise adapter. Thermals are as expectedly outstanding. Where the blower cooler would run at 40-50 idling, 70 degrees gaming, throttle at 84 degrees and pushes 90c stress testing. Two Noctua's has changed that to IDLE: 32c Average: 38c Intensive Gaming: just about 55c on average Stress testing: Just about touches 68c Note that this is with the low noise adapter, which specifically restricts 25% of your fan speed. On a GTX1080ti FE, this is fantastic. I know these temps might be somewhat normal in stock fan cooling GPUs, but they cannot do it in near silence like this. Downside: I spent £50 on two fans and £55 on the heatsink. So it's a £105 modification to what was supposed to be a £345 auctioned used GPU. Some could argue the total price and the performance it produces is well within its value.

I originally disregarded fans as an unimportant part of my setup, and opted for the absolute cheapest ones I could find. I couldn't stand the very loud noise they created, and so I took a gamble and went right to the other end of the spectrum. Of course, it cannot be denied that these fans are pricey, but they are absolutely exceptional. Unlike many people, my PC sits underneath my desk, and with 3(!) of these in my system they are effectively inaudible in an virtually silent room at 45% load (that's 1000 rpm each). I have various preset fan speed configurations, and under the highest performance setting, where each fan is running at 1500 rpm, they are still quiet, in my opinion. At full speed, they are loud (not louder than the competition, my point is simply that they aren't absolutely miraculous, they do still get loud sometimes), but due to their incredible performance you should never need to put them at full speed. They come in some of the nicest packaging I've seen in a while, with all the accessories you could need, and just generally feel very premium. Whether they are right for you or not depends on your priorities, as they are expensive, and other fans at considerably lower price points do a sufficient job. However, I like the peace of mind of knowing that my PC is being kept nice and cool and healthy, and for that these fans do a brilliant job. Them being whisper quiet is also, of course, a great bonus. Would highly recommend.

I refuse to use anything but noctua in my builds, I have a dh-15 but the fan is too big for my ram slots, so have replaced it with this 120mm pwm fan. Just perfect. Keeps my current CPU cool and will keep my future builds to cool for many years to come I'm sure. Comes with lots of accessories, including a splitter, spare bumper and a cable to reduce its noise (and speed, not really needed if you have pwm headers) Everything about the fan reeks premium quality. It's heavy, the performance is top notch and despite it's brown colour that won't match all builds, it looks great. Does come in black for those that care.

Bought this fan to replace my case fans. I had high hopes, and was still pleasantly surprised. For context, my old fans didnt make tons of noise, but under load you could hear the fan speeding up. I listen to white noise to sleep, so the hum, whilst noticeable, was not annoying and there was no "whine". I bought this fan purely to act as a exhaust as my PC has a small case and is running a 4070ti and a Ryzen 5800x, both of which run notoriously hot. The glass side panel kept getting extremely hot, to the point that I couldn't hold my hand in it for longer than a few seconds. After installing this fan, not only does my glass panel remain cool to the touch after hours of long gaming sessions (1440p at 164fps), but the fan is insanely quiet. I genuinely expected it to be around as "loud" as my old fans, but with better performance. Id go as far as to say that if I replaced all of the fans in my case with Noctua, the PC would literally be silent. I don't go out of my way to review many products but honestly this surprised me enough that it was warranted. 10/10

I was a bit skeptical about ordering these, they are expensive. However I got them at a decent price. Everyone has been saying Noctua fans are the best etc. I read some reviews on these fans too. I have a Fractal Design Define C TG case. It comes with 2X Fractal design X2 GP-12 fans. I put them both at the front of the case as intake and bought a Be Quiet fan for exhaust at the rear. In the recent hot weather and while playing extended game sessions I found my GPU and CPU getting extremely hot. I performed the following personal test Room temp 23.2c (measured with a basic digital thermometer) at the side of the case. I ran Folding at home for 30mins which uses both CPU and GPU at the same time. With the X2 GP-12 CPU 78C (read from Ryzen Master software) GPU 71C Junction Temp 87C (I'm not sure what this is but it's taken from Radeon software, I assume memory). With Noctua NF-A12x25 Room temp 23.6c (0.3c higher than before) CPU 74C GPU 69C Junction temp 85C Also I didn't realise that the X2-GP12 fans are not PWM so I believe they were running at 100%. Even putting my hand in front of these Noctua fans you can feel a huge difference. They also come with handy cables, one to make them silent (basically stops them from running at higher speeds), and a double fan connector, so I bought 2 of these fans I was able to use that one cable and connect them both to that and then just connect that cable to one slot on my motherboard. They are a bit more noisy than the X2-GP12 however when playing games the GPU fans are a lot louder. I was also thinking would it be better to buy 2x 140mm fans for better cooling and sound. It's a shame these aren't available in 140mm (yet) or black (yet).

Bought this Noctua 120mm fan after much deliberation. I even consulted with Noctua directly before my purchase. I'm on my fourth pc build now, and the Cryorig Lumni cpu cooler, although very good, was being let down by the factory installed fan. Simply put, the Cryorig fan had developed a very irritating undulating whine, that was at such a frequency range as to be heard even when wearing headphones - even at speeds varying from 800rpm - 1000rpm. Any faster and it would drone. Now the Noctua seen in the pictures runs at 1300rpm and is whisper quiet, and for someone who loves a quiet pc when browsing, gaming or working on tee shirt designs, this is sheer heaven. Asides from the aesthetic aspect of colour clash, I'm more than happy to compromise. This review is being written on the same day of delivery and installation (which is the following day from placing my order - thumbs up there) so I have yet to run this on full load during online gaming, or designing and music playing. But a quick check on Core Temp as I write this shows it running at 31 deg C. So very happy. In conclusion, from my own personal perspective, if you can handle the odd colour scheme buy without hesitation is you want near silent performance combined with effective and efficient cooling. A great purchase and worth the price.

I originally bought these to test if they are really as outstanding as people say. In the past, I’ve owned other fans, some of them quite expensive, yet they still had an annoying hum or unwanted noise under load. Noctua? A completely different league! 😍 I am honestly amazed by the quality. These fans are unbelievably quiet, even under heavy load. Words can’t fully describe it—you simply have to experience it for yourself (or more accurately, not hear it 😉). The next day I noticed they were sold by SCAN, and that only confirmed I had made the right choice. SCAN only sells top-quality, tried-and-tested products, and these Noctua fans are a perfect example of that. To sum it up: if you’re looking for fans that combine extreme build quality, perfect craftsmanship, and absolute silence even under stress, stop searching. Buy Noctua and you’ll feel (and not hear) the difference from the very first use.

These fans you can tell are very well made, they are very quiet and they deliver a lot of cooling, i use Noctua fans on every build i do for that very reason. I would love to see them do an rgb fan one day as i love rgb but that should tell you how much i value Noctua fans that i would sacrifice rgb for them. I have the NHD12 air cooler for my CPU as well which in my opinion is still the best you can buy even though it is huge. If noise is why you are here don't forget to enter bios and make sure fans are set to pwm not dc and also install fans with the rubber mounts rather than screws. These fans do not whine so you will be hard pressed to hear them. The picture above shows them along side 2 other noctua fans i already had, still a build in progress but this is in a d7000 corsair case and they are used for a side vent, the rest of my fans are noctua 140mm fans

Very efficient, and not too noisy. Somewhat expensive. I wish I had a couple more for free.

Excelente en todos los aspectos. Ofrece un rendimiento sobresaliente, manteniendo un nivel de ruido muy bajo incluso a altas revoluciones. La calidad de los materiales y la construcción es claramente premium, y el control PWM permite un ajuste preciso según las necesidades del sistema. Aunque su precio es elevado, la calidad y el silencio que ofrece lo justifican plenamente.

素晴らしいファンです。とても静かです。

Installed them on a radiator they keep the CPU much cooler, AND they’re much quieter than the ones originally came with it! No humming or loud noise even when they’re at high speeds, and at normal CPU usage you can barely hear them. These fans lowered my CPU’s temps by around 10-15c, I didn’t expect them to be that much better from the previous ones.
