i5 3570k with stock cooler:
Idle: 55C
avg: 70C
Full Load:90C+

Now with new Noctua cooler:
Idle: 22C
Avg: 30C
Full Load: Never reached 40C!!
I am extremely happy! I really thought my i7 3570k cpu was defective but it was really the intel stock cooler that was horrible! I had to downclock my cpu from 3.4ghz to 1.6ghz just to avg 60C(Yes I said 60C, and yes I said downclock!) I don't understand why intel provides horrible stock coolers when it can't even cool the cpu.

I am so happy with my Noctua, right now I have a lot of programs up and it's sitting at 26C, I actually love this cooler more than the hyper 212 evo.

Experience: 1 Years
Amazing quality, fit finish
Excellent unit with dual fans running, extremely quiet. Has been used on a Giagbyte 785 U2Sh DDR2 system and currently installed to Gigabyte GA990FXA AM3+ w a FX8350

Keeps temps low and is an excellent heatsink when you are height restricted. IMHO Noctua makes one of the best if not best heasink/fans.

Experience: 1 Months
Purchased 2 years ago and finally put to use. Got lucky that the brackets still fit.

Runs cool and quiet. Includes an extra fan adapter which came in handy...turns out my ITX mobo only had 1 sys fan + 1 cpu fan
Couldn't use the smaller fan on my Gigabyte ITX interfered with RAM clearance (despite using cheapo low profile heatsink sticks).
Purchased when it was on sale for $40. Steal of a deal for an ITX build!

Experience: 90 Days
low profile-good quality
none,good sale price too
good low profle cooler. works well wiyh 2 fans.

High quality. Excellent performance for its size. Fits into smaller cases, with both fans or even smaller cases with the extra low profile configuration. Quiet. High end PWM fans. Easy installation. Lots of accessories.
It seems like a fair price for the quality and all of the accessories, but unfortunately the full price is a bit difficult to justify unless you really like good quality case and cooling components.
This cooler is only for people who need a specific size of cooler, and then at that this one is definitely pricey at the regular price.

For this specific size of cooler, this is as good as it gets. There are lots of reviews online which state that its thermal performance is above what would be expected for its size. It is very quiet, and very easy to install.

A cooler master Gemini s524 would be a good alternative if it could fit into your case.

It fits comfortably into my Lian Li V-351A case. I would have gone with something a little more basic if I could have found it for a good price, but I never saw any good sales on any such coolers.

There's not a lot of options for medium/small sized heatsinks that can still handle a 125 watt cpu (phenom 965 in my case).

It's really, really nice. I tested it using the maximum heat test in Prime95 overnight with a 300Mhz overclock (3.7Ghz). The cpu stabilized at 53 Celsius (although with the sides of the case off). This isn't really an overclocking heatsink, although you certainly can with some systems.

I set my CPU back to normal speed but with an undervolt, and the cpu stabilized at 46 Celsius using the Prime95 Heat torture test (again, with the sides of the case off.

My case is warm with the sides on, so I won't be doing any overclocking (not that I really want to anyway). However, this cooler is good if you have a hot case, as it is definitely going to outperform other cpu coolers at this specific size.

Keeps my 3770k at 25c idle
Easy to mount
good quality thermal compound
Fit in my case with no issue with both fans
Did not block any ram slots
Lost my only PCIe slot on my mITX board :(
Does the job well for an HTPC, fans don't get load even under load, came with excellent instructions, pretty big for an mITX board so I would look into it work if you want to use with and also have a video card with your mITX.

Experience: 1 Weeks

Solid construction
Nice mounting system
This is one of the only heat sinks that will fit into the cooler master elite 360. The mounting system is super solid, as long as you don't mind having to remove the main board for installation. In the dual fan configuration, with the low noise adapters it runs super quite and significantly cooler. Best quality overall, thanks noctua and ncix!

Comment: The NH-L12 functions just as well as it looks.
Posted by: BernardP @07/02/12
Comment: If you are building a high performance small form factor system though, you need to consider that things like coolers and cases will be considerably more expensive. If you are prepared to spend the cash, the NH-L12 will serve you well.

Comment: Pros: Small and compact size, Good performance, Quiet operation, Easy installation, Low profile mode. Cons: None that I found.
