Features:

  • Premium quiet slim fan, 120x120x15 mm, 12V, 4-pin PWM, max. 1850 RPM, max. 23.9 dB(A), >150,000 h MTTF
  • Award-winning A-series design with Flow Acceleration Channels and Advanced Acoustic Optimisation frame for superior quiet cooling performance
  • 120x15mm slim design ideal for low-profile CPU coolers, HTPCs, ITX builds, space-restricted applications etc.
  • 4-pin PWM version for automatic speed control via 4-pin PWM fan headers, 1850rpm maximum speed (1400rpm with supplied Low-Noise Adaptor)

So for builds that 25mm fans are slightly too thick, this is a perfect solution. Otherwise, stick with whatever brand fan u like

Haven't tested the radiator fan-temp, but on full speed, it is a bit noisy than 1350rpm Arctic F12, which I give 5 stars without hesitation. The air flow is concentrated comparing with Arctic F12, which feels like a ring air flow. I did feel the air pressure is a tad stronger at full speed. To be honest, if Arctic makes 15mm fans, I will not buy this one, because Arctic fan gave me good experience, and also provides 6 years warranty. Only reason to buy this was because I need to put 360 radiator into Define C TG, but there is not much space for regular 25mm fans. All things putting aside, this fan is excellent, only con would be the high price. However, You will get some spitter/extender cables, so considering those prices, it is fine. It is more like a fan combined with some accessaries sold for a relatively high price. Very quiet, very quality build, soft pads are big pluses. One more thing I noticed was when it is running at full speed, fan blades are invisible, which is interesting. I like it. Maybe that's the reason it used such color. I didn't plan on this review, so it is completely write as I think. Finally, I decided to change 4 stars to 5 stars. It is expensive, but everything else related to a fan is satisfying. I only have one fan, so I cannot test the radiator performance, so I will skip that. Final thoughts: For my current build, a relatively large case, I tend to use Arctic fans for 800-900rpm which return a really good temp result with almost no noise at all. If I need to build a tight small form case, I will definitely go with this one. Quietness is the only important thing for me. Otherwise, there are tons of cheap fans provide similar performance with jet engine noise.

Excellent fan

This is another awesome fan by Noctua. I use it it as an exhaust fan case in my Node 202, and for that role I couldn't think of anything better. It's virtually inaudible until around 45%. Audible but tolerable from ~50%-70% and quite loud beyond it (but I'm a bit strict about noise, so your mileage may vary). Definitely not a big deal, since most motherboards allow setting up your own fan profile (i.e. fan speed vs temperature).

Fantastic quality as per usual

I bought two of these to fit inside of my Node 202's GPU compartment. The additional airflow really helps out my 1070 Strix in such a small space (~5 degree Celsius improvement). The additional slimness of these fans allows for more margin of error for cable management, meaning a little less work to ensure cables don't hit the fan blades on both these new ones and those found on my GPU. Being that they are slimmer than usual, they do have a bit more noise to them. However, Noctua includes a low noise adapter to force them to spin slower which really helped with that. Additionally they included a Y splitter to allow the use of two fans on one motherboard header which was very much needed in my Mini ITX setup. Quality and performance of these fans are probably the best in their class - a common phrase when it comes to Noctua's products.

Excellent slim 120mm fans. Perfect for htpc builds.

Bought these for my Phanteks Evolve Shift HTPC case to replace the 2 Noctua 140mm Redux fans that I ended up returning because of their thickness. These are quieter and feels like they push air out better than the 140mm ones. Only negatives I have is the color scheme doesn't fit in 90% of most builds but hopefully some aerosol dye for plastic or fan grills fixes the issue. Also the fan splitter it comes with has a 4pin and 3pin end instead of both ends being 4pin.

Works extremely well in an Mantiz Venus MZ-02 eGPU case

The latest version of the Mantiz Venus eGPU case (mid-2018) uses a 120mm x 15mm PWM fan that's not very quiet. This Noctua fan is an excellent replacement for the OEM fan in that case. After swapping it out, the system seems quieter, but the airflow is still just as good. I just wish it was easier to disassemble the Mantiz case! Compared to the Mantiz OEM fan, this Noctua fan looks and feels much higher quality. It really is a premium fan, and the high price reflects that. But to me, it's good insurance that the fan will last a long time and protect my valuable video card. My only complaint is the ugly color that doesn't match anything in my system, but luckily the fan is completely hidden within the Mantiz eGPU case... not worth taking a star off.

Noctua, the Mercedes of fans.

Love these fans, even at high RPMs they still are much quieter than most fans set to lower RPMs. Though they are pricey, the price is worth the peace of mind and peace and quiet. Right from the start you can tell the quality, the packaging is bar none, it is almost an experience in itself. You get a few accessories, like a splitter, rubber dampeners which double as screwless mounts, and a low noise filter, which when put inline dampens the max RPMs on the fan, which in all honesty you can achieve the same results if your motherboard has PWMs on it, if not then you can use the filter to make your fans quieter at 100%. Overall I am very pleased with my purchase and would recommend to anyone looking for a high quality fan that's easy on the ears.

I used the rubber mounts and I couldn't be happier. This was my first time using noctua fans ...

I mounted fans where no fans have been before. I have a fractal meshify c case and mounted these slim fans in-between the front io pannel and dust filter to help the hot air escape the rad mounted to the bracket on the other side. I used the rubber mounts and I couldn't be happier. This was my first time using noctua fans and I see why people use them. A premium product.

Slim, quiet, high quality and attractive.

Not only is it quiet and designed to be used in spaces where a standard fan won't fit due to it's thickness, it comes with a variety of cables of use depending upon your overall configuration. A 4.25" extension cable, a 13" extension cable, and a 5.25" "Y" adapter cable such that two fans can be attached to one fan power header. All of these with a sturdy braided sheath such that no loose wires are exposed. I hadn't been aware that it came with these cables, and was pleasantly surprised. I'm using two of these with a Deepcool Gammaxx 400, where there wasn't enough space for standard thickness fans on the one side (I got the 2nd one purely for aesthetics). How quite are they? I can't hear them, at all. I know they are running, as the system BIOS will pause the start-up if the CPU fans return an error signal, which hasn't occurred; otherwise, I'd wonder if they were on.

Quiet thin and powerful

Five out of five. I have 4 of them in RVZ03 case. 3 of them are bought individually and 1 is with the NH-L12S. One of them apparently was restocked. Screw holes were a bit loose and missing some plastic wraps but that doesn't affect the fan itself from functioning properly. Below 1000RPM they are almost silent. At around 1500RPM is the sweetspot for this fan, it is audible but manage to move a lot of air through. The fan max out at 1800RPM and the noise is very audible, but not obtrusive. I don't know how Noctua did it but the airflow sound is very natural and not annoying to my ears. Plus, it is moving massive amount of air into my ITX case.

Simply amazing

Switched 3 upHere fans with these in my mini-itx build, and I am thoroughly impressed. Being PWM, noise levels went to essentially silent, especially on the silent profile in the BIOS while also dropping temperatures. Temperatures dropped ~5-6 degrees on my CPU by simply having a higher quality fan that can push more air. Also came with some really useful low noise adapters (which I didn't use) and some extension adapters which I did use. Would have been nice if the screws were black and the fans were a different color, but these are minor gripes. Noctuas really are the best fans out there.
