Designed and optimized for Intel LGA115x processor with not more than 65W TDP, the Noctua NH-L9i is a premium grade CPU cooler that delivers excellent cooling capacity and quiet operation in an ultra compact package. Measuring only 37mm in height, this cooler flawlessly fits most HTPCs and small factor form systems, and the 95 x 95mm footprint means it will not even block the first RAM slot and the closest PCIe slot on mini-ITX motherboard. The highly efficient NF-A9x14 fan supports fully automatic speed control via PWM. A Low-Noise-Adaptor can be used when necessary, to reduce maximum fan speed from 2500 to 1800rpm. And with the solid, easy-to-use SecuFirm2 mounting system plus 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.

Caution: Caution: 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).

37mm Low Profile

General information

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

General information

The NH-L9i has a 95x95mm footprint that complies exactly to 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

General information

Most Intel LGA115x based mini-ITX mainboards 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

General information

The highly optimized NF-A9x14 premium fan features Noctua’s exclusive 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.

Low-Noise Adaptor

General information

Allowing reducing the maximum speed of the NF-A9x14 fan from 2500 to 1800rpm, the included Low-Noise Adaptor (L.N.A.) makes it possible to achieve near-silent setups using CPUs with less than 65W TDP.

Custom-Designed SecuFirm2 Mounting for LGA115x

General information

The NH-L9i bundles a custom-designed, backplate-less SecuFirm2 mounting system for LGA115x that offers extended compatibility with mini-ITX boards and makes installation easier than ever, all while maintaining the trusted SecuFirm2 quality.

NT-H1 Thermal Compound

General information

Noctua’s much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.

5 out of 5 eggsNice! Quiet. Keeps 4790Ks cool.

Pros: I bought two of these for i7 4790Ks even though they're only rated for 65 watts TDP or less. They are extremely quiet. My CPUs (not overclocked) idle at 29-31c and playing Fallout 4 at 33-35c. I quit the game and had Speccy running already and that's what it read so maybe it goes a couple degrees higher. Stressing the cpu's with CPUz will top the temps out at about 73c after a few minutes. That's a bit warm but I read 90-100c is when to worry, and anything is better than the loud stock intel coolers. Installation is really simple. No brackets. Just screw it in through the back of the mobo. Doesn't touch the RAM.

Cons: None.

Other Thoughts: There is enough thermal paste (grey/silver in color) for a pea size application with a little left over. Excellent packaging with dense grey foam. They are barely audible with the case off and I did not use the noise dampening cable that came with the coolers. The coolers are of high-quality construction and heavy. I'm a new Noctua fan.

4 out of 5 eggsCan't Go Wrong

Pros: Quiet
Size/Low Profile
Secondary Accesories

Cons: Color

Other Thoughts: I bought this to replace the CPU cooler that came with my CPU. Installation is a breeze and the cooler is easily removable. The size of this helps free up a small amount of space, that would have otherwise been taken up by much bigger CPU coolers. This cooler comes with Thermal Paste and a special cord that limits the RPM's so it doesn't become so audible. There really isn't too much to tell here, you get a little extra for what you pay for, and it does its job extremely well. My only problem with this product is the factory set color, which doesn't blend well with anything in most PC setups. If they offered this in black, it would be perfect.

5 out of 5 eggsIt is a true Noctua grade.

Pros: Beautiful and well designed.
Good material
Very, very quiet
Well suit my H-frame mini
CPU temp 29-31C idle

Cons: There is always one side being blocked. Either the RAM or the CPU power supply heatsink. Luckily, this wont influence the cooling much

5 out of 5 eggsGreat Fan, Quiet!

Pros: I bought this for my HTPC to cool my CPU. It fit very well into the small case I had it enclosed in and the fan makes not noise what-so-ever unless you hold your ear right up to the case itself. Keeps the CPU nice and cool as well. Installation was really fast.

Cons: There really was nothing I did not like about this product.

Other Thoughts: I would recommend to anyone who has a small form factor case that needs a great cooling solution.

3 out of 5 eggsHeatsink is great but...

Pros: The heatsink fits the socket perfectly. Mounting is precise and easy. There are no clearance issues with anything around the socket, including memory, capacitors and PCIe. 40 degrees C idle temp, ~55 full load.

Cons: Fan was great for a year. It now makes grinding noises like a few of the other reviewers have noted. Will try for a warranty replacement with the fan since it says 6 years so we'll see!

Other Thoughts: The packaging was 1000% overkill. Thick cardboard with monster padding inside. It would be a great box for a Faberge egg or something.

5 out of 5 eggsGood enough value for my needs

Pros: Noctua quality; reasonable price, mostly favorable reviews at all web sites

Cons: This cooler won't bring my CPU to ambient temperature but, after a few days for the thermal paste to melt in, it remains in low 30s 9Celsius, of course)

Other Thoughts: Most Intel CPUs run hot, especially the latest ones due to the narrow thickness and continuing defiance of companies to conform to Moore's Law. I only have a 4790 on an 1150 motherboard in a Mini-ITX case but I wanted it that way. I usually build a PC every 2 or 3 years so why spend a pile of money just to be the leader of the pack for a few months? The machine is plenty fast enough for me, running an SSD on WIndows 10 with a Nvidia960 and 16 GB RAM. I don't overclock much either so what's the point in getting liquid cooling? I'm too old to have a sugar mama to give me a hefty allowance for my passions. Even after a heavy load of multi-tasking, the temps drop down to the low 30s fast enough for me. I chose wisely so the cooler and all the other parts didn't break the bank either.

5 out of 5 eggsExpensive and worth it

Pros: I took a chance and it's really nice. Idles around 25C - I don't really rage on my comp too hard but I haven't gotten it to break 55C when I have. It's on an i5-4590S (65W TDP) so it's not exactly being challenged either, just perfect for a reasonable processor and tiny case.

Cons: No cons, you just need to take care you don't move it around too much while getting the first screws going in the back.

5 out of 5 eggsPeople are using it wrong

Pros: Extremely low profile, you will be hard pressed to find a cooler smaller than this.
Quiet, I never hear this thing running, even under heavy gaming load.
Tiny footprint, literally compatible with everything.
Cools just as expected (see other thoughts).

Cons: None, this performs exactly how you should expect it to (see other thoughts).

5 out of 5 eggsGreat product

Pros: Contains High quality parts. Pretty heavy.
Has extra screws if you want to install a larger 92x25mm fan, rather than have the A9x14mm fan.
Comes with plenty of Thermal Compound NT-H1.
Comes with an L.N.A. which attaches to the fan cable, and slows the fan speed to reduce noise.

Cons: must be installed directly to the motherboard. Unlike most that have an adapter you connect to the back of the motherboard, this screws directly to it. Not at all a deal breaker. It just makes removal a little more difficult.

Other Thoughts: This thing is built sturdy. No cheap parts on it. It feels like it was built to last. Almost like only engineers made it, without the uncesseasy input from some Marketing guy who wants it to "look cool"
