Noctua NF-A14 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (140mm, Black)

I bought these based on Noctua's stellar reputation without expecting much more than a quiet replacement for my case fans. I was pleasantly surprised when they turned out to be better than I had expected. I use these connected to the PWM fan headers on my motherboard and they are so quiet, way more so than the Phanteks case fans they replaced. To be fair to the case fans that were replaced they were close to 5yrs steady use and were showing the abuse of constant use. I like the vibration dampeners on the Noctua fans, being able to swap those out to match your color theme is nice, and I intentionally choose NON-RGB fans for my case fans as my setup has plenty of RGB already. These fans move a ton of air and do it quietly, they hardly ever ramp up because my case has good airflow and they provide plenty of air. I was rather surprised that my GPU temps dropped with the addition of these fans, that is just how much better the air is moving in my case. While I am using these as case fans they would make EXCELLENT radiator fans if your looking for replacement fans for a 140mm or 280mm radiator. They are definitely worth the premium in price, build quality is superb, you can feel it when you hold them in your hand.Note you may want to pickup additional PWM splitter or extensions if your case is huge, or your motherboard doesn't have headers in a convenient location. I didn't run into this but I could see it being an issue for some. The fans do come with a 30mm extension attached to the short cable on the fans so for example in the pics I included I could have just used a y-splitter on the two in the front and attached one of the 30mm extensions to that and ran it to the header on my motherboard. Cable management and routing is a case by case and personal choice kind of thing though.Bottom line, these are excellent fans.

I love them! simple and cool looking. I currently have 5 of them in my all black build and the noise level is still nice and quiet! If you are using a full tower PC case, make sure to prepare yourself with Noctua NA-SEC1, 4-Pin Extension Cables (30cm, Black). "with all current Noctua 5V, 12V and 24V fans"

These are great fans. I bought them as replacements for some extremely noisy (tone) Arctic P14s. While these are very pricey, I felt safe buying them and I was not disappointed.A couple of things. First of all, there is a white box on the underside of the case that has all the extra colored dampeners (and screws). The front of the case only shows one of each so make sure you check the other side!Secondly, the connector wire off the fan is *extremely* short (laughably short). You're almost certainly going to have to use the included extension. There is also no daisy chaining of these fans, so you'll need a splitter or hub if you want to do this.Lastly, I don't think they have threaded holes, but they do come with self-tapping screws. It's somewhat irritating that they aren't threaded given their price.These push a ton of air and a very quiet except for at the higher RPMs (which is a given due to how much air they push). If only they weren't so pricey. That's the big downside here.

I replaced a smaller, 3-pin fan with this one. It's very quiet and works much better than the fan I replaced. A 4-pin fan gives the computer much better control over the speed of the fan. Install was quick. The hardest part was choosing which color to use.

I bought these to replace the fans in a Thermaltake TH420 AIO (which I very much regret buying), because the fans it came with were rattling like crazy above 40% speed.These Noctua fans were delivered overnight, and have solved my noise issue completely. I'm even able to adjust my fan curves to push a bit more air with these fans, and maintain the same quiet noise level. Very nice.I do think the different color noise absorption pads are unnecessary though... it is extremely wasteful, since most of the pads will simply go back into the box, unused. In addition, they only give you 4 of each color, so you can't use the same color for all 8 corners of your fan, you have to choose two colors.In addition, while two of my fans came with black pads, one of my fans did not have any black pads - it came with brown instead. So, now the colors just don't match in my case, which is pretty dumb if you ask me.Still... I won't see it most of the time, unless I'm digging around in the case. So minus some dumb silly things, these are still 5-star fans.

For the quietest fan money can buy, I would highly recommend this fan. It does an excellent job at staying quiet while providing great airflow. However, I did run into a problem when I received it—all the screws were stripped. This was pretty frustrating during assembly. Despite that issue, the fan itself works really well, so if you're willing to overlook the screw problem, it’s a solid choice.

Defintely moves a lot of air and not too loud full speed. Can only imagine once the fans are put on a curve how much more quite they will be. The only thing I didnt like and I took of a point for this was that for the money the cord was too short and is built as an extender coming of a connector right off the fan. If you have a tower I recommend you buy an extension cable.
