NF-A12x25 PWM chromax.black.swap, Premium Quiet Fan, 4-Pin (120mm, Black)

I bought two of these for exhaust fans, have had them for around 6 months at the time of writing this. They are quiet and effective. I’ve had excellent temperatures using these, but admittedly I don’t have much else to compare them to. These also include some colourful rubber corners in a few colours and some seals to help keep them quiet and efficient. Noctua isn’t cheap but you get what you pay for. These have been perfect so far.

Quality feel, heavy rigid frame and fan/hub blades, the fan motors are twice the size if not more compared with the noiseblocker rgb fans I replaced, they are also much more quiet at full load. i have 10 of these beasts mounted on 2x 360 and 1x480 rads, + an additional 4 on the side case ports next to the mobo tray, and a 140mm version of this fan on the exhaust port, and with my corsair commander pro set on a quiet profile curve, even while gaming my RTX 4090 OC sits around 37c and 13900K CPU around the 50c mark, my nvme drive also in the loop sits around 32c. Only when i ramp up the profile to extreme can you really hear the fans but that would be max rpm where as quiet mode holds the fans between 1k to 1.5k rpm, and on the extreme profile while gaming cpu and esp. gpu which stabilises closer to idle temps. Definitely the best quality case fans i have ever built a pc with, even though the price is high, it is reflected in build quality and the operation, having 15 fans that can be set almost completely silent while still able to cool a cpu and gpu that is known to run hot is impressive, highly recommended for air and water-cooled setups.

Excellent fan, superior build quality, great performance and quiet throughout the range. Was apprehensive at first due to the cost but delighted now.

Yes, they're expensive (especially because the Chromax versions don't come with the extender cables which means you might need to buy those separately), but when you factor in noise and performance you really can't buy better fans. If you want good performance and low noise, this is the best you can do.

Incredible fans - first thing i do with any build is buy a set of these - whisper quiet up to 30% rpm and they have a 0% pwm signal so stop completely at low temps - Noctua is still the GOAT

Excellently performing fan, these are quiet and move a lot of air. I am currently using this in a Thermalright Phantom Spirit 120 and it is a perfect drop-in replacement for the original fan. The accessories that come with it are nice although I feel that the inclusion of all the extra colour variants for the corners is a bit excessive and wastefull. I do wish the cable was longer and didn't require an extension to reach headers on the board but I appreciate that the shorter cable that could be extended appeals to a wider demographic than a long cable that someone may want to be shorter. Overall, I highly recommend these fans to anyone who takes PC cooling seriously. They are best in class and worth the cost.

Really high quality build, the fans are very well made and have a reassuring weight to them. The cables are also very impressive and easy to work with, unlike the cheap plastic ones other brands use. I purchased three of these to replace a set of Corsair elite fans that were not only too noisy themselves whilst running; but also created resonance in my case leading to a very annoying humming sound. You can hardly hear the Noctua and I must admit I'm far happier with the more subtle look (ie no LEDs). I'm also convinced average temperatures are a few degrees lower. I cannot recommend these highly enough. Yes they cost more; but given the role they play keeping far more expensive components safe, their quieteness and the build quality I think they are an essential buy.

Ordered 10 of them for my O11d XL, they're super quiet, no annoying RGB and keep everything cool. I use them in combination with the thermaltake FP which supports up to 10 fans. I have 3 connected to my AIO and 7 connected to the thermaltake FP. I don't think you can beat these fans in noise normalized thermals, I have tried Cosair QL 120's, Lian li AL120's. The Corsair ones the LED's started dying making the RGB look terrible, the AL120's started developing bearing noises in the fans. I have owned 3 brown coloured A12x25's and have been using them for couple years now without any issues, its ashame these other companies can't put out such good quality fans like noctua. I like noctua but am not a fan of their brown/biege colour scheme, these chromax ones are much cleaner in appearance.
