I bought this because I needed a 140mm fan with a standard, square frame to fit my case's odd front-intake mounting system. It seems that the few 140mm fans that don't suck are of the 120mm mounting hole variety, which are handy for heatsink placement but wind up being a hassle as case fans. Noctua's previous 140mm fan was, in my opinion, one of their less impressive products. The A14 finally gives Noctua a 140mm fan worth their name. Its bearing runs silky smooth, and the fan is near-inaudible beyond 12 inches, running at 800 rpm while moving more than sufficient air for a properly laid out case. An intake fan doesn't need to blow leaves off your components; it just needs to provide current that reaches far enough to lower the case's ambient air temp in the right places. Noc has moved beyond mere acoustics to engineer some fans that produce refined, focused current. The result is a fan that doesn't seem like it's pushing a ton of air, but manages to be effective in getting it where it needs to be. I noticed temp drops compared to my previous fan (a fairly high quality one at that) that was running 100rpm faster. The silicon dampeners are a nice touch, though really the fan is balanced and smooth running enough that they probably aren't even necessary. It comes with a voltage limiter, but the thing is so quiet at its 800rpm full speed that I can't imagine ever using it. That attached wiring is rather short, but an extension is included. That's actually nice, since for placements where you don't need much length it prevents having a bunch of slack. Now Noctua just needs to offer some different colors. I'm not hung-up on their current color like some people are, but some coloring that isn't so conflicting with just about every case interior would be nice.

★★★★★Quiet operation. Great quality.
The fan is extremely quiet and has enough air flow for my needs. If the color of the fan matches your setup, it is a great choice.

★★★★★Worth the Wait
Yes it came three days late, who cares. I rarely write reviews but this one time I will. I am using this as an - external - fan I placed on top of my fanless Mini ATX PC to cool the surface a bit. (to usb port) Meaning, the fan actually sits on top of the machine and the machine is about 2 feet away from my keyboard. Reason I invested in a fanless PC is that I am particularly sensitive to mechanical noise. Can't hear this fan. I tried. I just cannot hear this thing. Not an excessive amount of air flow but silent. Not whisper quiet, silent. It does cool the internals of my machine a bit more, I placed the fan one inch above the vent, super nice build, and silent. Why did I not do that earlier ?

★★★★★Noctua Premium Fan for a truly silent system. Great fan.
This review is short. I ordered this to keep my cable box (HD-DVR) from misbehaving. I noticed it runs hot and I grabbed a cpu fan on a wimp and gave it a try by placing it on top of the unit. It cooled the box nicely but the noise was ridiculous. But the box started to work well without needing to reset often. So I looked and looked for a silent fan. Although bigger than I thought I needed, I went with this unit. It comes in a beautiful package with lots of extras. I ended it connecting it with the additional wire reducer for a total silent operation. You can't hear it at all when the equipment is completely off. I have a nice Home Theater system and no fans run when everything is off. The Noctua is the only one 24/7. And you can't hear it at all. And that was what I wanted. Funky color which is visible slightly over the box but overall great product. Highly recommended.

★★★★★Works well; fussy to mount
Fussy to mount - I could never get their special "noise-dampening" silicone screws to work, but if you use regular screws, it goes in fine, though the ones provided are *barely* just long enough if you screw it in tightly. The fan seems to work well. My computer stays nice and cool.
