Summary: I purchased this CPU cooler because it has great performance and low noise by a very reputable company. These features make it one of the best CPU coolers for the price. Like most product categories, if you spend more money, you get better performance and more features. CPU coolers are no exception. You could opt to spend no money can use the stock CPU heat sink, which is fine if you do not overclock, but you will have to tolerate noise and increased temperatures.
Summary: The heat sink itself is amazing and does come with heat sink compound, which I wish I would have known when buying it. The fans are cheap looking, but then again the price is right. I put this on an ASUS P8Z77-V LK with G.SKILL Ripjaws RAM and ran into clearance issues with the second fan. My solutions was to eliminate the fan that blows air over the fins and just have one sucking air from behind which is then blown into a case exhaust fan.
Pros: Great quality heat radiator Nice fit and finish of hardware
Cons: Cheap looking fans Instructions for install were terrible Can interfere with other MB components
Summary: Purchased from a Newegg listing on an auction site which cannot be named. I would have also liked to say something about the the shipping but they also say I cannot do that. I suspect they have good reason.
Pros: The temperature of CPU with all cores at 100% load was reported to be around 80C with the stock Intel cooler on my Xeon CPU (LGA1150) E3-1230 v3 @ 3.30GHz. With the NH-U9B-SE2 the temperature is about 60C so it is better than the stock cooler by about 20 centigrade degrees. The ambient was about 23C in both cases. I can live with that. Even at full speed it is no noisier than the stock Intel cooler.
Cons: My Thermaltake V3 ATX Tower case has an opening beneath the motherboard so you do not have to remove the motherboard to attach the backplate. Unfortunately the opening is smaller than the backplate on one side and the standoffs that hold the motherboard up are not high enough to provide clearance for the backplate between the motherboard and the case. I ended up having to use a bench grinder to grind part of the lip off on the end of two arms of the back plate so it w...
Summary: Yes this thing is huge on top of my ASUS Sabertooth motherboard and I like it that way. Bigger is better as far as air coolers go and this one fits the bill nicely. I would give this 5 starts easily however, and this may be my lack of understanding, I did not see in the Amazon ad that it included all the mounting hardware as a complete kit. I purchased a separate install kit thinking I needed it to complete the install. I ended up spending $20 that I didn't need to.
Summary: You can mount it so the fans blow up and it won't block anything at all Bought with an intel 4770, it keeps it cool under load and is very very quiet.
Pros: Very quiet, fairly simple to install and it came with thermal paste.
Cons: The cooler itself is a bit big, you'll have to be careful about which way you install it as it may block some of your ram slots if mounted side to side. You can mount it so the fans blow up and it won't block anything at all.
Excellent heatsink, easy to install, 3-pin fans instead of PWM fans

Summary: Fantastic heatsink. Installed on my Intel LGA 1155 motherboard. Was replacing my stock heatsink on my HP HPE H8-1124 pc (listed as medium size tower) with Intel core i7-2600 cpu. Unfortunately HP had a non-standard backplate that went with the Coolermaster stock heatsink, so I had to order a Molex standard 1155 backplate (which was not easy to find).
Summary: This cooler is efficient and works very well for its size. Noctua makes a very good product. There are two issues that need special attention when you buy this cooler. First is the fan mounting clips can interfere with the first memory slot (Slot A1) on some motherboards. It interferes on mine which is the ASUS F1A75-M Pro R2.0 motherboard. I thought this might be a problem so I only purchased two G.Skill Ripjaw memory sticks, and installed them in memory slots A2/B2.
Summary: Fan mounting could be figured out to not interfere with the first memory slot. I expected this problem, so I only bought two mem sticks and use A2/B2 dual channel slots, but it would be nice if I could use all 4 slots if I wanted to.
Pros: I chose this cooler for a desktop horizontally-oriented pc, so a shorter cooler was required, and Noctua makes excellent products. I have it mounted on an ASUS F1-A75-M Pro mATX MB. Keeps the idle temps around 32C and under full load temps at max 45C no over-clocking. So, it's doing a fine job.
Cons: My only con has to do with the fans...they're not 4-pin PWM fans. Now I know some motherboards can adjust voltage to control fans speed, but not all can. Of course you don't know until you try it. Of course mine does not, and I had to purchase new 4-pin PWM fans and now I have a much quieter pc. Noctua makes 92mm 4-pin PWM fans that would work fine, why don't they just use those in their CPU cooler kit instead of the 3-pin connector fans? C'mon Noctua!
