Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown)

Despite its premium, it is still as loud as other fans, as well as its airflow. There are alot more other fans out there that does the same but at more than half the cost.

not as quite as I had hoped but probably meets specifications. I have not tried the slower speed option yet.

Great quality and quiet fans. I personally also love the color.

replaced the dual fat 360 fan with two 60mm noctuas, had to splice some wires and trim the plastic shroud but man is it worth it, my 360 is super quiet now

solid product. good air flow. and quiet.

I used this to replace a noisy fan in a PicoCluster Raspberry-Pi case. Its a kind of thick fan, but in the PicoCluster this isnt a problem. The fan is definitely quieter even at full speed, and keeps things suitably cool.

These are very high quality fans and great for vibration or noise-sensitive applications. The only issue is they dont move as much air as I would have expected at the rated 3000 RPMs. If you have these in an open environment, you absolutely need to use them with a baffle so that they dont interfere with themselves in order to get any noticeable pressure out of them. They will work best in a small closed space that needs air flow.

So the fan in my treadmill sounded like a Blackhawk landing....Horrible whine. Pulled it and replaced with this. Cant even tell it is running. Super quiet! Amazing

I think these fans are overrated. I’ve bought several Noctua’s at different sizes. They all tend to have weak air flow. This one doesn’t blow much air and it’s relatively noisy compared to a cheaper NB fan. Although the NB fan also has poor airflow.

Bought 2 to replace the originals in my pc cabinet. Cant hear them!
