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.

Exactly what an HTPC needs

Pros: Smaller, quieter, and more effective than stock Intel cooler. HTPC tight packaging demands something like this. HTPC which sits near your main viewing area needs to be quiet.

Cons: Noctua is pricey, but no one else makes something like this.

Other Thoughts: Noctua NH-L9i (or L9a for AMD) is about as small as it can get before exotic engineering of proprietary and custom packaged laptop cooling. It has laptop attributes though: copper base, aluminum fins, and heat pipes to make outer fins effective. It gets the job done for light systems. It may not be effective if you try to cool an I7 on ITX based gaming rig. You need a bigger case and a bigger cooler to handle the heat. It keeps the CPU cool, the fan can often slow down to idle, and its quiet even at medium speeds anyway.

Compare to stock. With an I3 or I5 based HTPC, the stock cooler will usually fit. However stock struggles to cool in such a tight package, stock is a lump of aluminum, and stock has no heat pipes to enhance the benefit of the outer fins. Stock fan is loud in dB but also has poor frequency tuning to further amplify the annoyance experience. So stock gets hotter, the fan needs to move faster, and it is noisier at all speeds.

Pros: Very Quiet. Premium packaging. Felt like I bought something special. Solid metal logo sticker.

Cons: As simple as it is to mount it, it's a little janky. I almost didn't think the screws were long enough.

Other Thoughts: I used this for a work pc build using an i3.

Works Great :-)

Pros: I bought this to use on my new build ..I am using an
Intel Core i3-6300 Skylake Dual-Core 3.8 GHz LGA 1151 65W BX80662I36300 Desktop Processor Intel HD Graphics 530...the Noctua NH-L9i, Premium Low-profile CPU Cooler for Intel LGA115x is very quiet and runs smooth it keeps the i3 processor between 29c and 34c depending on the load I have never used Noctua brand before and so far I am impressed and I like the fact that the fan is so quiet … the install was easy and simple and does not take up very much room so it will not interfere with the memory / Ram on your motherboard ...I am glad I made the choice to purchase this :-)

Cons: None so far

Other Thoughts: I would recommend this to anyone the quality is great though the color of the fan may not be a desirable color the quality and performance more than makes up for it … thermal paste it comes with is of good quality I like the packaging ...it comes packaged in a box which also is very good quality its solid not flimsy when you open it there is foam to protect the heatsink and fan from damage during transit they include all the necessary hardware for the install and thermal paste all packed professionally using good quality materials I could not be happier with this I am very impressed and I would recommend this to everyone I knew as soon as I opened the box I had a high quality product it is well worth the money ...with this one you get a lot of bang for your buck :-)

Not happy with it, at all.

Pros: - Packaging is pretty nice. You can tell they spent a lot of time on it
- Quality is great, for the price

Cons: - Can't keep my i9-9900k cool at all. My CPU maxes out at 100C, then downclocks to save itself from burning out.
- Took off the Low-Noise Adapter, and it still can't keep my CPU cool
- Reapplied thermal paste, same problem.
- Even with my case open, it still won't stay cool.

Other Thoughts: - I wouldn't recommend if you have an i9 processor, or any other CPU that gets really high-temp.

Good replacement for the stock Intel CPU cooler

Pros: -Very quiet
-Excellent build quality
-Excellent packaging
-Good thermal paste is included
-Easy to install

Cons: -Somewhat expensive for the thermal performance offered

Other Thoughts: I'm using this with an Intel Core i3 8100 in a Mini-ITX build and have been quite satisfied so far. It's much quieter than the stock Intel cooler I am using in a similar build. The price is somewhat expensive, but it's not that bad. Working great for an HTPC/light gaming build.
