Noctua NF-A12x15 PWM chromax.Black.swap, Premium Quiet Slim Fan, 4-Pin (120x15mm, Black)

Excellent fan. The fan noise is low as well as the bearing noise being basically non-existent. Applying a fan curve will make this perfect for any small form factor build. The fan is virtually noise free until used at higher rpms. The only downside would be if you're building in a case like the Fractal Terra, there can be a bit of wind resistance noise from the fan if used as the bottom intake/exhaust. Overall great fan and I would highly recommend to any in need of a fan to either use as a cpu fan, or as a case fan. Moves a ton of air while being incredibly quiet.

I haven't built a PC in over ten years so I researched and agonized over pretty much every component before I bought them. Any apprehension you have before spending money on these fans is totally understandable. They're expensive, but what I got in delivery was worth it.The packaging is quality, with the fan and connected extension, and a separate container tucked in the box for the colored anti-vibration pads.The fans are slender, heavy, and when you flick them they'll go for what seems like forever. The color anti-vibration pads are a neat touch and come in multiple colors. Kids wanted each to be a rainbow.Installation had some headaches because the provided screws didn't mesh well with the holes in my NR600 case. They required a lot of torque to tap into the plastic of the fan but tightened securely after that. Removing them, in the incredibly unlikely event that you might have a mental lapse and install the fan pointing the wrong direction, is a cinch.When the time came to turn my new PC on I admit I panicked because I couldn't hear the fans. With my ceiling fan going I can't hear them at all. These run a nearly silent low frequency hum that I can barely hear over ambient noise.There's a premium price to pay for silence with air movement but it's totally worth it. Just be aware that unlike the brown and tan version, there's no splitter included. You'll have to find your own splitter or a PWM header for each fan if you want speed control.Pros: Scary quiet. Moves a lot of air. Feels sturdy. Stickers!Cons: Expensive. Weird short cord with an extension attached. Expensive.

great fans, used like 6 in my nr200 and they’re super silent, really great build quality

These PC fans are perfect for anyone looking for reliable cooling without the extra flash. They were easy to install and set up, and they work exactly as expected. While they don’t have RGB lighting, they’re a solid choice for performance-focused builds.I’d definitely recommend them to anyone in need of quality PC fans at a great value.

I needed some slim case fans for an ITX ~27L case where regular case fans were too tall. Just wished they had a white, gray, and red color options. Very quiet. Airflow is decent but not spectacular. Traditional Noctua non-RGB high quality. A bit pricey. Keeps the system cool enough so it performs its job.

Works great to cool my de-shrouded GPU, and stays quiet even at max RPM. Noctua is always a little more expensive, but it's always for a good reason. If anyone else is going to use this for a GPU de-shroud mod, I would recommend using a software called "FanControl" from GitHub (create a curve then apply that curve to the fan header on the motherboard). Now I don't even notice when my GPU is working hard, and it stays cool.

It has only been a handful of days since I installed this, but so far it lives up to the Noctua reputation. Thin, quiet, and efficient with a quality build to match.

I bought these specifically to fit into my FD Meshify C. These fans fit perfectly underneath the front mesh. I needed 15mm thickness fans because I have an RX 6800 on the way that is 325mm (photo shown is my current 1660 Super) - The RX 6800 won't fit with a 25mm fan front mounted inside, and a 25mm fan won't fit under the mesh without cutting. So these 15mm fans do work perfectly for my use case.The fan quality is fine - it's what you would expect from Noctua. I do have a few gripes though. The fans only have like half an inch of cord with the plug attached to it. Noctua does provide an extension, but then you have a bulky plug right at the corner of the fan which isn't ideal and I can imagine might be an eyesore in certain situations.The extensions I am not a fan of. The cover they use on the cord is like a rubbery texture and it kinks when you bend it due to the space between the cover and the cord beneath it. I can already tell dust is going to stick to it and looks bad due to the kinks where it bends. They also take up unnecessary space. I bought different extensions, but it's kind of annoying when you are already spending $25 on a fan.They do move air well for being a lower profile and aren't overly noisy. I'd like them better for like $20 and automatically including a longer cord installed without an extension. The interchangeable anti vibration pads are whatever, if you want to change the colors you can. It's cute, but I rock all black anyway.
