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

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.

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.

It is a good fan, powerfull and quiet. Used about 2 years. then replaced with higher airflow ones. Noctua is top brand when it comes to case fans. and Chromax is the one of the best products

My old PC fans were constantly buzzing, driving me crazy. I replaced them with these new fans, and they’re fantastic! They’ve completely eliminated the noise issue and run almost silently when not under load. I highly recommend them to anyone seeking high-quality, affordable fans for their PC.

Overpriced? Maybe a bit, yeah. Worth it? Yeah, probably. They work the same as the brown ones, except the cable terminates just 1 cm from the frame. Kinda annoying but also kinda great as it's allowed me to daisy-chain two of them real nice.Seriously though, exactly the same as the brown ones. Black gasket, 4 black corners, 4 red, yellow, green, blue, grey and white. so not enough to do all 8 but hey ho.

Do I really need to say anything, besides what already been said by everyone else?! They are notoriously quiet.My previous set of fans were the basic Fractal Design case fans, and upon installing these all over the case - the difference was astonishing, my PC went from "Hmm, it's kinda loud..." to "[CRICKETS]" not even noticing it!When it comes to temps, I am running an AMD 5900x, which is naturally, a very hot CPU and dependent of the CPU cooler itself, and a pair of new fans would not make a HUGE difference, however, I have definitely noticed a drop in temps all across the board (CPU, GPU etc)- Considering the build I have, the fact that it had made a slight difference just shows how good these bad boys are.Recommend!

The material feels premium and has a smooth finish, it is powerful enough to allow for good airflow. Very easy to install in multiple different builds. Cable is neat and professional , on the shorter side but you can buy extensions but my opinion is that it is the perfect size.By far one of the most silent 🔇 fan out there for its performance.

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.
