Noctua NF-A15 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

Always go with Noctua.

Like all Noctua fans Ive used, this fan moves a lot of air and is almost silent. Using it for a push/pull on a Noctua NH-U14S. Very effective.

I dont here anything from this damn fan, and thats with no restrictor pin, but I m running this dual fan on my Noctua heatsink, and I dont really feel like its blowing that hard, as well I equipped the recommended extra padded corners, but they arent needed, the normal ones minimize noise the same.

I bought this as an add-on for my Noctua heatsink that only came with one of these. A great fan for a great heatsink.

I have to eat a little crow regarding my earlier review. I had installed the cooler incorrectly (the most obvious mistake too), Id installed the cooling fan on the wrong side of the heat sink. My cooling fan was competing with the case air-flow direction, and with the case exhaust.

Great fan! Needed a 140mm fan with 120mm mounts and this was perfect. Great air movement and super quiet. Color sucks, but put a little effort in and you can paint the frame, pictures included. I would not suggest painting the fan blades as that may throw their balance off. The top/bottom of them is flat which works perfect for sitting over my HyperX RAM while theyre on my Noctua NH-D15.

These are the best CPU fans money can buy. I just put three of them in my new 2950X build. I may even swap out the top case fans for two more. They are silent, heavy duty, durable, and have the best airflow. Theres really no compromise with Noctua fans, just that you have to pay for quality which I dont have a problem with.

It is difficult to tighten the screws by hand, an electric screwdriver is necessary. In addition, I am very satisfied with the noise and air volume.

Extremely quiet and smooth running fan. Runs fine off the case fan header connector on Gigabyte motherboards where another PWM fan failed to spin up without changing bios fan settings.

There are less expensive fans out there and even more cheaper fans. I havent tried every fan on the market because Im not made of money but out of the fans Ive bought not only for computer cases, various CPU cooler and other projects these Noctua fans are great. I dont mind the colours but some people really dont like the usual Noctua colour scheme. I truly enjoy the near silence of these fans even when running at full speed. I bought one of their massive CPU cooling towers but with only one fan. Decided later to add the second fan just to see if it would help. I didnt really need it but with how quiet the first fan was I figured it wouldnt hurt to throw in a second one and see what happened. Even with the two fans I have to try to hear them. My cases fans are louder and are from a different manufacturer that are also supposed to be almost silent but arent as quiet as the Noctuas.
