Pros
Quiet and move a lot of air
Cons
expensive, boring color
Summary
This fan is very quiet and move a lot of air.
I can only hear a little noise at max setting.
Though it costs a lot, but it's well worth it.
Would recommend to everyone who doesn't care about the color of the fan.

Pros
Very quiet.
Cons
A bit expensive, but worth it.
Summary
I bought this fan to replace an Antec case fan that went dead. I couldn't beleive how quiet it was and when I first turned on my computer with the fan installed. I could barely hear it. I would definately buy this fan again when needed.

Pros
What you would expect from any Noctua fan. Quiet, lots of airflow, great quality case fan.
Cons
Wait for a sale. Twenty bucks is a steep price but you do get what you pay for.
Summary
I picked up two of the NF-S12B fans to replace two Coolermaster R4-L2R-20AC that barely lasted six months before they both started making noise.(Cheaper is not always better) Different blade configuration than the NF-P12 but they seem to work quite well as intake case fans. I am going to replace the exhaust fans as well on my case the next time these go on sale.

Pros
+Quiet
+Enough air flow for me
+Vibration dampers and lna/ulna adapters included
Cons
-Not much pressure
-Had one that vibrated(NCIX RMA'd)
-Now my power supply sounds loud
Summary
Picked up these fans for my FT03 case as intake/exhaust. They works as good as the stock fans and do so with much less noise.

One of the fans was causing the case to vibrate, but NCIX replaced it for me and the new one is all good.

Overall I would say these are good for a quieter system(silent if you use the ULNA and still quiet with the LNA). I am letting my board control them so they are very quiet at idle.

I would recommend these for system that value quiet over all else, while they perform very well for the noise level, they may not cope with some very hot systems and should not be used on tight fin heatsinks and rads(NF-P12 for those :)).

One down side to these fans is that you will notice anything else that is loud in the system after you get them installed.

Pros
Quiet
Moves good amount of air as exhaust fan
Excellent accessories
Cons
Rubber gromets little difficult to install.
Summary
Bought for $9.99 on weekend sale about 6 months backs. Still working great. Tough to justify the $19.99 normal price though. Using in Antec 1200 case removed the dual 120 exhaust fans and replace with just a single of this fan temps are just as good. The accessories very useful. Needed to undervolt another fan where the MB couldn't used the Low voltage adapter worked perfectly.

*EXPENSIVE
Summary
The only downside to these fans is that price. They do an amazing job cooling and make so little noise that it doesn't upset me. I would highly recommend these if price is not an issue.

Pros
Whisper quiet, efficient, well-made, sleeved cable
Cons
Colours are unremarkable, price is expensive
Summary
Overall I must admit I was plesantly surprised with this fan. I'm using this as an exhaust cooler on the rear of my case, since this fan is designed for 'open air' cooling, and not 'restrictive flow' cooling like in a CPU cooler. (If you want that, get the NF-P12-1300 instead.) I replaced a SilentX fan that had siezed after only a few years of use.

One of the things you will notice with this fan is that the blade angle is very high, almost 90 degrees. This makes it a great fan for moving air when there is no obstructions, although poor if there is an obstruction. Since they make two designs, they don't have to compromise with a fan blade design that is 'in the middle' of being good as a case fan, and being good as a CPU cooler. This fan does well at what it is designed to do, and when running the blades become nearly invisible. Nothing stands in the way of moving the air, which is why this fan excels at what it does.

Yes the cost is a bit high, but with a 6-year warranty this will be the last fan you need for quite some time.

Pros
This is the real deal. You need these fans in any silent case you want to build. They are the high-end fans of the market.
Cons
I know, they are twenty dollars each but I assure you they're worth every penny. Get them on sale and make your case silent.
Summary
These are excellent fans. In fact, the best I've ever had. I have used CoolerMaster noisy LEDy fans with lights and noise. Do yourself a favor and buy real fans. Buy Noctua fans.

Comment: OC Mod Shop review: The Noctua NF-S12B FLX is a well-built fan with a lot of innovation and thought behind it. It is on the pricier side, but these are also the Ferrarris in the case fan world
