Noctua NF-A14 FLX, Premium Quiet Fan, 3-Pin (140mm, Brown)

The best case fans you can buy, in my opinion. These replaced another set of Noctua PWM fans for me which were too noisy for my taste. These are perfect running the low noise filters.

Excellent fan.... moved a lot of air while consumpt modest amt of power... not to mention quiet.... nothing beat noctua... I tried Corsair fan.... doesnt come close to this.

Added two of these to the top of my case. Extremely quiet and pushes a ton of hot air out. They are really well made and you immediately can tell the great build quality when removing them from their boxes.

Extremely quiet and efficient. Keeps my case cool and air flowing well. Definitely will buy more in the future when I have need of it.

This fan is nearly silent, and moves a lot of air. I love it!

Excellent quality. Super quiet and hands down worth the price.

I thought the fan was too expensive at first, but changed my mind after installing it to my Define R4 and seeing quite a significant drop in temperature on my pc. Highly recommended!

Super quiet, exactly what i expected from Noctua. Comes with many cables to fit your every need

These were for a case exflow use, to draw hot air out. I got three of them, and they all were a bit noisier than just 3 120mm I had before. So not sure these bigger ones were worth the hassle. They are still great, and useful, and come with adjusters for speed and noise (Im using the lowest speed adjuster). The rubber mount pins and nice, and the rubber corner covers are nice too... but I knew of these since Ive bought noctua before ;)

Very quiet. Case runs significantly cooler than with stock fan. Very high quality look and feel. Would purchase again.
