Summary: 3 months in the fan went bad. Emailed noctua and got a response in less than 24 hours. Rma had me take a picture of my id and the fan side by side after I was told to break one fin. They shipped a new one next day. No muss no fuss. FYI, they rated their own fan harshly. It's been cooling a 3570k with the low noise adapter. 50 core/ 40-55 socket.
Pros: -small -quality -excellent Rma -low noise adapter makes it quiet
Cons: Not really any cons Does install weirdly but with a plan or a second pair of hands it's easy
Summary: Temp based using a Gigabyte GA-Z87X-UD4H-CF mobo. & a Fractal Design Core 3000 Full-size ATX Case (5 case fans that run in a push/pull configure). Plus G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900).
Pros: Much better than Intel's stock cooling unit. When heavy gaming my Noctua NH-L9i 95mm SSO2 CPU Cooler keeps my Intel Core i5-4670K Haswell CPU under 60 C degrees when fan is Full speed. Real Quiet fan! Easy install without removing Mobo. Great thermal paste. Extra long screws for a fatter fan up to 25mm.
Cons: Must run NH-L9i fans at full speed to keep CPU cool enough in gamming.
Pros: Works well if you install it correctly. I had to turn the CPU cooler around so that the vents blow the air out the sides toward the outside vents of the case. The fan blows the air down forcing it out the sides. Due to the mini-ITX motherboard design I had to rotate the cPU cooler so it would not blow against the RAM.
Cons: None that I can think of. Little tricky holding it in place while trying to screw it down.
Summary: I have this heat-sink on a stinger Z87 Micro-ATX board and fits the CPU intel (1150-Haswell) socket area for the cooler perfectly. So be aware that if you have any capacitors etc sticking out above the processor in the CPU cooler area, it won't fit on your MOBO. The fins on the CPU cooler are NOT flimsy and thin aluminum, which give the cooler a solid and sturdy build.
Pros: Easy installation, great build quality, low profile, quiet at low RPMs, color scheme
Summary: I bought this because the stock fan on my CPU sounded terrible. This unit is very quiet and super low profile. Installation is a piece of cake; 4 screws. I have had one issue so far with it, however. After playing a game, I noticed a slight chirping/clicking noise coming from my box. I opened it up and determined it was the fan on the NH-L9i. Absolutely nothing blocking the blades. I maxed out the fan speed, brought it back down, and the noise stopped. Weird.
Summary: I have to say that I was very impressed with this heat sink when I got it in the mail, it's built extremely well (as everything I've ever gotten from Noctua has been). That being said...it doesn't fit on my motherboard! It doesn't say so but you'll need so make sure you don't have any tall capacitors around the CPU or it will hit them...and I was so looking forward to using it! I have to give it 4 stars because of this.
Quiet, compact and powerful - perfect for ITX build

Summary: I have two itx rigs running nearly identical hardware (asus maximus impact vi motherboard + i7-4770k cpu), but different cases. I could not fit a liquid cooler into my other case, so I went with this Noctua. One uses the Corsair liquid cooler (H60i) and on the other this Noctua. Both are cpus are overclocked to ~4ghz. The Corsair runs about 5 - 8 degress celsius cooler on average. I am very pleased with the Noctua as it is nearly silent and very efficient at cooling.
