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.
37mm low profile
Due to the slim 23mm heatsink and the NF-A9x14 low profile fan that measures only 14mm in thickness, the NH-L9 stands a mere 37mm tall, which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers.
100% RAM compatibility
The NH-L9i has a 95x95mm footprint that complies exactly with the Intel LGA115x socket keep-out zone. This means that it won't cause issues with chipset coolers and doesn't overhang the RAM slots, so it's fully compatible with tall memory modules.
100% compatibility with PCIe cards on mini-ITX
Most Intel LGA115x based mini-ITX motherboards have the PCIe slot sitting right next to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95xmm sized NH-L9i provides full compatibility with PCIe cards.
NF-A9x14 PWM premium fan
The highly optimised NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9i to stay remarkably quiet.

The NH-L9i is a highly-compact low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first rate performance in its class, it is not suitable for overclocking and should be used with care on CPUs with more than 65W TDP (Thermal Design Power).

In all that time, it has never gotten audible, and temperatures have never gotten above 65. I, personally, find that unbelievable. I was advised not to even try i5 ITX gaming in this case without a closed-loop watercooler for the CPU. And yet - here we are. Zero problems.
Oh, a side note about Noctua's warranty: it's amazing. I did have an unrelated issue in 2014 with the fan bearings getting noisy. They immediately, with no quibbles, sent a replacement in the post. The replacement turned out to have the same fault; I emailed them again, and they replaced it again. No issues since, so I think I was just unlucky, but what a great company for service.
Box/Unboxing: The box and unboxing experience is very premium, you get some high performance thermal paste to the right, a low noise adaptor on the left, a very very nice metal piece to stick on your case above the cooler, then the cooler itself in the middle with the four mounting screws below that.
Thermal Paste: I didn’t use this as i’ve got some other stuff so unfortunately i can’t comment on it, but i looked it up and apparently it's actually pretty good compared to some mainstream pastes like the Arctic MX-4
Low Noise Adaptor: Again, i don't use this, but, i can without a doubt say this is not needed at all. Don’t understand why they include this as the fan is by far the quietest fan i’ve ever seen (Or heard haha) im my life, but they do include performance metrics on the box for how the cooler performs with and without the adaptor, but honestly as i said, it's really not needed as the fan is already silent without
Metal Peice: Not much to say about this, it's like a said really premium, unlike all other companies that just include a crappy sticker, this is actually a piece of metal with some 3m tape included already on the back, all you have to do is peel it and stick it.
Cooler/Fan: Very nice fan, cannot put into words how quiet the fan is, i’ve used a lot of fans in my time being on pc and i’ve never heard one as quiet in my life, at 1200rpm you cannot hear it, over fans i’ve tried at that speed sound like jet engines.
As for the cooler, it is also very nice and does a good job keeping my CPU cool, nice and low profile and fits perfectly in the Fractal Node 202.
Mounting: The mounting process is really easy and simple and what i like best is that there is no backplate, never used a cpu cooler before that doesn’t have a backplate and i must say it's a luxury to have
Performance: As i’ve already said the fan is nice and quiet so i won’t talk about that anymore, so i will now move on to my temperatures.
So i have this is the Fractal Node 202 which is a very small form factor case and the cpu fan is the only source of cooling the CPU gets , which by the way is the Intel Pentium G4600 so take those into account, also for thermal paste i'm using Thermal Grizzly Kryonaut and with all these factors in mind i get 30c at idle and at full load i get 60c, not even kidding i’ve never gone past 60c on this CPU which is insane for the setup i have.
Overall: It's just a great cooler by a great company, it's very well thought out and you may think £36 is a lot for a CPU cooler but you get a lot included and as i said it's all very premium so when you take all that into account its actually a bargain! 10/10 Highly Recommended!
For that reason, I usually run a water-cooled system, but these are prone to occasional pump failures. After much looking, I settled on the NH-L9i as an alternative to water-cooling. Part of the reason is it's small size not further restricting internal air flow.
The box, on arrival, feels quite heavy for its size. This, generally where cooling systems are concerned, is usually a good thing. A good heatsink and fan setup can be considerable in both size and weight. The surprise here is the weight for what is an incredibly compact unit. This set me thinking, as I genuinely have never seen something so small even come close to what it claims it will do.
I needn't have worried, as it performs fantastically. My CPU idles at around 45 degrees, and rarely gets above 60 degrees even under the stress of heavy graphics and video work. I'm not a gamer, so I do realise that stress is very relative, but my previous water-cooling system often peaked towards 70 degrees under stress.
The NH-L9i runs remarkably quietly, even without the low-noise adapter. The adapter is an extra cable which controls the fan speed to reduce noise. The trade-off is higher temperatures, so it is purely a personal decision whether you use the cable or not. I haven't used it, as I would prefer lower temperatures because the PC is in use for 12 hours a day. Even so, the fan is incredibly quiet. There is a barely perceptible hum at idle temperatures, only becoming noticeable when there is a significant temperature and fan speed increase. Even then, most of the noise increase comes from the additional CPU fan fitted in the case.
I cannot recommend the NH-L9i highly enough. Fitting was easier than most, but still a bit fiddly although this shouldn't put anyone off, and performance is excellent. For the money, I doubt you'll find better.
Original review for FreeNAS build below:
I bought this to replace the stock Intel cooler for my FreeNAS build. It's only an i3-2100 so not exactly taxing, but the stock cooler was noisier than I'd like.
I didn't need the extremely small size - it's currently occupying a Define 7 case - but I went with the low profile one in case I decide to repurpose it down the line in a small form factor or a smaller rack mount server type case.
It's very quiet, which I have come to expect from Noctua, and feels very well built. Temperatures on my NAS are excellent, with peak temps at about 40 C if the system is under load (Plex transcoding usually) and around 30 C when the system is light/idle.
I used it in 2 setups:
On a i5 4570, does a brilliant job at cooling
On a i7 4790, you can take a look at the thermals while under 100% load in a Folding @ home project. Gaming wise, it's not bad either. I would say an average of 62 maybe, never beyond 70 (Celsius)
It's the easiest fan to install I've seen (just a couple of screws and your done
It doesn't take a lot of space, since it's Low Profile
It's very quiet
And comes with goodies, like a Noctua adhesive logo (feels like a badge) and thermal paste
For me it's a 5/5
