Pros: Awesome fan! I bought one for my Fractal R5 Define and comparing it to the stock Fracal Case fans this one is 10x better. I put my hand next to the 2 fans to see if i'll notice a difference in the amount of air they move... And I did! The 2 were at same noise lvl (silent) but the difference in the amount of air the Noctua moved compared to the stock Fractal was roughtly twice+ (3x more) They might've been spinning at diff rpms I don't know... I'm just letting u guys k...
Cons: Price. A lil bit steep otherwise i'd have 9 of them in my case
Summary: Recently upgraded the GPU video card in one of my rigs from on-board Intel to a GTX 970. Due to the increased heat production I figured I'd open up the top hole in my Fractal Design Design Mini and put this guy in to add some increased airflow. Works like a charm!
Pros: Pretty much silent, even at the highest speed. Moves a decent amount of air for being totally silent. Comes with regular fan screws and rubber (silicone?) mounting pegs if you don't want to use the screws. Also comes with various adapters including low speed/low noise adapters. I don't know why you'd need a low speed/noise adapter considering how quiet this thing is at full speed....
Cons: A big honking fan. I remember when 140mm fans started coming out my friends & I made jokes about them wondering what the heck a fan that big would be good for. Seriously, though, the only drawback is that if you're using one of these then you have a really big hole somewhere in your case. This fan may be silent, but the other parts inside your case may not be and their sound has a big hole to come out of. Not a con of this fan, just a con of all 140mm fans in general ...

Summary: So quiet I actually got concerned and did some temperature test to make sure my CPU was cooling properly. It surpassed the original fans ability to cool easily. Will buy again when I build another system.
Summary: I bought this along with a CoolerMaster JetFlow 120 - I prefer CoolerMaster because it feels more solid and this Noctua is actually just a touch wider than normal. I had to slice off the latch of my motherboard aux power connector. The fan I replaced, standard ANTEX top fan, fit fine, but this was about 1/8 inch too wide. I'd also note that the CoolerMaster has actual threaded holes and standard bolts whereas the Noctua has the cheezy squissy plastic psuedo-screws.
Pros: these fans move soo much air, but the insane thing is how quiet they are!!! i plugged in a "standard" 120mm fan, and even with 6 of these bad boys in my case, the 120mm was all that i could hear!! i have used so many fans i've lost count: noctua quality is unparalleled.
Cons: still not convinced with the colour. would love a black/white fan to match my 780T
Summary: Seriously .. these are creme of the crop. alot of people not keen on the color. These things reek engineering and quality. But Ill take performance over glittery blinking fans any day. I have used corsair, antec, nzxt and they don't come close to these when it comes to amount of air moved and how quite these are. They give you attachment for reducing the noise even more at the cost of rpm's, but really you wont need them.
Pros: Best Fans I have ever bought. Move tons of air and can't even hear them. You have to put an ear to them to hear them.
Summary: Easy direct replacement of existing case fans. 3 pin cables for direct attachment to motherboard fan headers with a 4 pin adapter if you want to run it off the power supply feeds. Unbelievably quiet and very effective. I can barely hear my system running and it's sitting right next to my desk. 6 year warranty so not sure how you can go wrong here.
