The NH-U9B SE2 continues the legacy of Noctua's classic NH-U9 series of compact premium coolers, which have received more than 100 awards and recommendations from the international press. The new SE2 version lends itself to use in quiet HTPC’s or smaller cases and adds support for LGA1156/1155 as well as LGA1366 via the latest SecuFirm2 multi-socket mounting system. Topped off with Noctua's award-winning NT-H1 thermal compound as well as two premium-grade NF-B9 fans, the NH-U9B SE2 offers a complete quality package for excellent quiet cooling performance.

5 out of 5 eggsPretty rad

Pros: Compact compared to 120 coolers, awesome noctua colors (a little sarcasm but you can at least say you have one of the best air cooling brands on the market). Keeps my 1150 i5 around 30 degrees at 3.8ghz when im servicing my pcs water cooling loop. This is usually in my home theater pc and is awesome for that due to its small size, quietness, and efficiency.

Cons: I really have none. Some people might dislike the colors, but i say they are scrubs and dont understand that noctuas are the choice for air cooling

Other Thoughts: If you want a cheap cooler that will do the job and is quiet then get this thing. If you are a nut for better cooling, i would also suggest looking into noctuas larger coolers and i promise you wont be disappointed. only reason i got the small one was space requirements and im not upset with what this thing can do.

5 out of 5 eggsGreat Product

Pros: Knocked 40 Degrees Celcius off my CPU temps when video processing. Easy installation. Very,very quiet using both fans, there is the option to use only one. Comes with the thermal paste which saves buying it separate. Easy installation , no problems, the directions are super easy to understand.

Cons: None.

Other Thoughts: Newegg delivered very quickly. Very happy with the Service.

3 out of 5 eggs

Pros: it's cool. (pun intended)

Cons: it's a bit smaller in person
and orientation on AMD is limited to vertical only.. so you'll be blowing the hot air up.. (theoretically sucking in hot gpu air)
or you could blow air down using the top as intake (think htpc) now it's the side.
never my preferred mounting orientation, I prefer to exhaust out the rear of the case. pulling fresh cool air in.
Googled this issue and found noctua does offer a mounting bracket for free to mount this correctly.
guess it was just an "oops" during manufacturing.

4 out of 5 eggsLove the heatsink

Pros: Heatsink is very high quality and has very high performance
CPU runs cool even under stress test

Cons: Not a fan of the 2 fans come with it.
It's not PWM fan to start with, and it makes a noticeable but slight click noise. It's not loud but the nature of the sound is annoying.

Other Thoughts: Locking mechanism may interfere with your RAM on mini ITX build. Plan ahead.
One fan IS enough for non OC
To be fair, the stock intel cooler also make a similar clicking noise, but I didn't pay extra to get the same quality. Going to try replace the fan with a Noctua NF-A9 PWM see if things get better.

5 out of 5 eggs

Pros: Really nice it fits my LGA 1150 socket no issues what so ever, easy instructions, easy install. CPU temperature at max load for my i5 is 55C which is really nice to see after using the stock cooler for so long.

Cons: None its quiet and I like it.

4 out of 5 eggsCheck your RAM clearance on mITX builds

Pros: Overclocked i7-4790K idles at 34 C, got it up to 57 C with prime95. I'm using both fans, pointing out the back of my Corsair 380T. Not too loud either.

Cons: The RAM in the slot closest to the CPU on my mITX board cannot have a cooler on it. There is exactly enough space for a bare stick of RAM to fit under this cooler. My mobo is an ASUS z97i-plus.

Other Thoughts: The directions that come with it are a bit hard to follow but I was able to figure it out with a little tinkering.

5 out of 5 eggsVery effective cooler

Pros: Keeps CPU cool. about 30C on idle, 40C ish on load, Never break 50 for me.

Cons: it's big so make sure you plan your layout well

Other Thoughts: For mITX build, the cooler is very likely to get in the way of RAM.
Installing only 1 fan would fix this issue. Or install it in another direction.
I had no problem running just 1 fan, even quieter.

5 out of 5 eggsLGA 1150, First time computer builder. Seems to be solid.

Pros: -seems to work
-My idle CPU temp is 24-25 C. Unsure how to check in game (cause I am a noob)
-Assembly not too complicated
-Noctua is 1337
-comes with thermal compound

Cons: -Super old model in tech years

Other Thoughts: Only con is my input isn't too weighted since I am new to the knowledge base of computer components.

5 out of 5 eggsAmazing CPU Cooler

Pros: Upgrade from Normal Intel CPU Cooler to this cooler, it's amazing!
- It comes with 2 fans
- You have the option to mount only 1 fan
- Is compatible with the most popular LGA slots (1150, 1155, etc. etc.)
- Never seen my CPU go above 50C under heavy load, with ONE fan, imagine 2.
- The heat sink is amazing, seems to keep the CPU very cooled.

Cons: Just some little complaints,
- It came with anti vibration strips which I didn't really know how to place them, and the instructions didn't really say how to put them on, so I didn't.
- The fans are not controllable, they only use 3 pins instead of 4 so it doesn't let you customize the fan settings.

Other Thoughts: Without the "Anti Vibration" Strips it doesn't really vibrate, and it stays REALLY cool with only ONE fan, so I imagine you'll get even better cooling with the 2 fans on, my motherboard could only support 3 fans, (Including the CPU fan and the fans already in the case) So I couldn't use the 2 fans, but the quality of this CPU cooler is amazing, Great job on this solid product Noctua! :)
