The NH-L9i is a premium quality quiet CPU cooler for Intel LGA115x based HTPCs and Small Form Factor systems. At a super-low profile of only 37mm, the NH-L9i is ideal for extremely slim cases and due to its 95x95mm footprint, it provides full compatibility with tall RAM modules and VGA cards on mini-ITX mainboards. The custom designed SecuFirm2™ mounting system for LGA115x makes installation a child's play and thanks to the highly optimised NF-A9x14 premium fan that supports fully automatic speed control via PWM, the NH-L9i runs remarkably quiet. Topped off with Noctua's renowned NT-H1 thermal compound, the NH-L9i fuses everything users have come to expect from Noctua's larger coolers into a super-compact package for slim HTPC systems.

2 out of 5 eggsCools the same as stock Intel heat sink

Pros: Fits well for mini ITX builds. Doesn't go beyond the square footprint around the cpu.

Cons: On Intel 4790K processor, idle temps in 40-50C range and 60-70C+ under load. For a premium cooler I was expecting better performance. The Noctua performed about the same as stock. I returned mine and got a Corsair H60 liquid cooler instead which is idling in the 20's and under load in the 40's & 50's. Much more to my liking. Much harder to fit in a mini ITX, but it was with
worth it.

3 out of 5 eggsBad fan

Pros: Small. Works.

Cons: Fan making grinding noise after 3 months of 24/7 use. Noctua's RMA process is.... well.... it could be easier.

Other Thoughts: Nice HSF overall. Probably easier for me to buy a new fan vs jump through Noctua's hoops.

3 out of 5 eggsWant to Love it but...

Pros: Really good build quality
Great packaging
Great thermal paste
Great size

Cons: Unfortunately, it just doesn't perform near as well as I expected (i7-3770). The online reviews that have done real thermal tests also conclude that it's barely cooler than a stock Intel fan. Luckily I plan to re-use the fan and have some thermal paste left but I had to switch this out for something that keeps cooler.

Other Thoughts: I wanted so badly to love this product-- it has everything going for it except that it doesn't cool very well. That's a major problem for a CPU fan! I'm still impressed with build quality etc but I simply can't overlook the performance.

5 out of 5 eggsDoing the Job

Pros: Works,no problems,I am happy with my purchase.

Cons: Just 1 con,the amount of thermal paste they give you is only enough for 1 application was hoping for more :(

Other Thoughts: Love the quality of the item.

Really wish Noctua made 230mm fans.

5 out of 5 eggsJust what the doctor ordered.

Pros: Highly effective, quiet, reasonably priced

Cons: None

Other Thoughts: After struggling to find a cooler that would be compatible with my Cooler Master Elite 120 Advanced case while being effective enough to cool a 4770k in a cramped environment I settled on this little guy. I have been very impressed with its ability to cool while maintaining relative silence. Even slightly overclocked my processor remains cool.

5 out of 5 eggsgreat little cooler

Pros: Small, quiet, extremely well built, nice finish and packaging

Cons: none-- it does what it's supposed to do

Other Thoughts: I needed a cooler with a very small footprint for my small mini-itx build, and this was the best fit. Had an installation question and contacted Noctua customer support, and they responded immediately and were very helpful!

5 out of 5 eggsElegant and amazing

Pros: My first Noctua HSF. I wish they would make water coolers. I need water cooling on my primary desktop, but would love to run all Noctua coolers in all of my systems, based on my experience with this one alone. The packaging probably adds to the price of the unit, but when you open the box, you will be wowed. Elegant, professional. The unit itself is heavy (stout) and much thinner than I imagined. Left me more room in my Silverstone case than I had thought.

Cons: Price. But you get what you pay for. Certainly not worth knocking an egg off.

Other Thoughts: Replaced a stock Intel HSF on an I7-2600k. Running at stock speeds (for now). Idle temps stayed the same. Under load, stock HSF ran 42C, the Noctua runs 32C. Both fans were run at max (gonna play with BIOS settings if and when I try to overclock) and the Noctua is quieter (but not silent, obviously, at max speed). Would buy again, in fact, I may replace all the coolers in my SFF mITX systems with this one.

5 out of 5 eggsGreat small form factor

Pros: Small form factor
simple square shape
only 37mm high including fan
great air flow for a fan thats 120mm
very quiet fan
noctua quality build

Cons: pulls air in and you need to purchase other screws to invert the fan
works better for 65 watt cpus
doesn't handle heat as well as a more beefed up noctua

Other Thoughts: I would definitely recommend this unless you run into the problem where the heat sink air flow gets boxed by the ram , the gpu and motherboard heat sink which defeats the purpose of the cooling the cpu

5 out of 5 eggsGreat Product

Pros: - Quiet (with low noise adapter included)

- Provided thermal paste and mounting solutions are rock solid and easy to install.

- Beautiful packaging and build quality

- Extremely low profile, absolutely no problems from height of the cooler, and no ram interference.

Cons: none

Other Thoughts: This cooler was purchased for a custom pc build inside of an NES; space was at a premium, and airflow was low, however, this cooler has really pulled through! there is no trouble with my ram modules, and it leaves lots of room from the top of the case; almost being shorter than my standard height ram modules! absolutely wonderful product.

5 out of 5 eggsExcellent Cooler

Pros: I bought this to replace the stock cooler for my Core i5 processor and the low profile design made it fit perfectly on my Mini ITX board inside my Corsair Obsidian 250D.

The easy to install mounting system made the entire installation process painless.

The low noise adapter was a nice touch although I didn't end up using it.

The quality is excellent as I've noticed a 10 degrees drop in idle CPU temperature when operating the cooler at full speed.

Cons: I haven't encountered any problems with this so far, although it does tend to make a fair bit of noise at full power which was required when gaming.

Other Thoughts: Overall awesome cooler. Very pleased with the results, my CPU runs a lot cooler than stock. As expected, excellent quality from Noctua.
