Pros
Quiet and efficient, comes with metal and rubber screws
Cons
UGLY.
Summary
Function over form is clearly Noctua's game and it shows. Brown on beige is ugly in pretty much any case. I was going for a cohesive design inside and out, but I wanted the best quiet fans so that threw things off. Other than that I have no gripes because...

These fans are the best. Quality costs money and you can hear where your money went with these.

Efficient airflow, but most importantly, QUIET. I have my desktop for audio production so quiet is a priority. These are literally the quietest case fans money can buy. If that's what you're after, don't even bother with anything else. Seriously, they're that good.

Pros
In 2 pack bundle price is more decent
Great product
Silent
Cons
Not a real Cons but not a "big" air performer, see summary
Summary
This fan are nice pieces or ART
They are very good if you don't need lot of air and no noise. Low wattage pc is perfect. In my principal one, I use 2 of them in my pc and 1 Noctua 14mm in a Lian LI and it is near limit in full cpu gpu load but works perfectly (i3 3100 3.1 wt Corsair A70 and Gigabyte 6770 all both passive)

I also use it in Small pc like Sonata III with dual core low consumption. I put passive heatsink on cpu and let the airflow doing the job by the Noctua (back fan on the case).

Noctua is very nice product. Never had a single problem with their fan over the last 4-5 years.

Cons

Summary
Bought these for use as case fans, and needed them to be Quiet! they are definatly very Quiet. You can't go wrong with Noctua fans. They just pull enough are out of my case to keep the air flowing. They are rather expensive but well worth the money spent!

Pros
Nice and quiet!
Cons
Looks... But it's Noctua!
Summary
If you're looking for a side panel fan, this puppy is your fan!

I picked up 2 of those and as a duo, they did a nice job of moving just enough air (remember, this is for the side panel of my case) and keeping it quiet while doing it.

No complaints at all!

Pros
Working as intended
Cons
A little bit expensive?
Summary
A "quiet" fan is subjective. But it's perhaps one of the quietest I've had so far. I'll probably check for other fans next time. I heard of some good ones for a little bit cheaper

Pros
Very quiet on low mode
Good performance on high if needed
Cons
Ugly color scheme
Summary
I got one of these for an older case that had 1 for exhaust. I built a WHS box so didn't need a lot of airflow due to lower temps. I did require the fans to be very quiet since the server box is on all the time and in an area that is exposed. On the low voltage mode it is virtually silent, just a very very faint noise is audible. I highly recommend them for a silent build such as the one I did.

Pros
Quiet, Unique Design (Very Noticeable, in a good way) Strong
Cons
None? Rubber grommets included are kind of standard... Would've preferred silicone grommets. (But not much of a matter, just picking at things.)
Summary
Great fan. I bought two of these to replace teh stock fans on my Corsair H70.

I have them with the Ultra-Low adapters... They do what they were meant to do, and they do it well.

Pros
Silent, superb build quality.
Cons
Cost.
Summary
This fan is slightly under power in terms of air pressure or air velocity, but enough to feed fresh cool air for most PC setups.
This fan is superb in build quality and ultra quiet. This is without any doubt the quietest component among those moving ones inside my case.
When it comes to fans, I always go with Noctua.

Pros
very quiet
good air flow
seems quite robust
have lasted since i bough it
Cons
maybe the brown color?
Summary
these fans are very quiet, they look kinda of weird, but they perform, i use these and nexus fans only, and its maybe little quieter than the nexus, but still impressive in my opinion
