Noctua NH-L9i-17xx chromax.Black, Premium Low-Profile CPU Cooler for Intel LGA1700 and LGA1851 (Black)

Many of these reviews are spot on. I used this on a i5 13500. The stock cooler was very noisy. While I do have a ASUS TUF gaming mobo with 32GB RAM and a RTX3060, this is not really meant for gaming. I just don't like slow rigs. So this cooler should suffice in terms of temps. So I ended up going with this low profile CPU cooler even though my box is full size. Just taking it out I can see the good quality. And when installed, there is a significant improvement in fan noise, this thing is really silent. I agree with the reviewer who said more than two hands is useful. I held the cooler while someone else put in the screws from behind the motherboard. And in my case, I had to remove the motherboard screws and take half outside, because my case did not provide access to couple of the screws behind the motherboard while installed.

My AIO was not working as well as it should have, and I needed a fast solution since my idle temperatures kept climbing relentlessly... nearly 85°C! To avoid long term damage to the other components, I replaced my NZXT H1 v1 small form factor(SFF) rig's OEM AIO Cooler/Fan completely, and solely used the NOCTUA NH-L9i-17xx chromax.black instead. The difference was immediate, and the temperatures easily are in the high 30°C to low 40°C range when idle. I am thoroughly impressed with the quieter fan as well. Excellent product, that I can highly recommend to other users.

Very compact and low profile. Super easy to install. Requires access to the back of the motherboard. Noise level is super low with the low noise cable but would not recommend to use with a power hungry CPU like a 13900k or 14900k.

A low profile cooler like this one is an absolute necessity for a small form factor Mini-ITX chassis. I used this with a build in a Joyjom two slot Mini-ITX chassis ( https://www.amazon.com/gp/product/B0BLXY7S4Y/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&th=1 ). The stock cooler on the i5 12400 is 15mm too tall in the Joyjom chassis and I suspect a number of others that support multi-slot cards with a PCIe riser behind the motherboard. This cooler fits with about 5mm to spare never-the-less it is silent as you'd expect from Noctua despite the blades spinning in close proximity to the ventilation holes. Ran the brown one for about a year before changing over to the black for purely aesthetic reasons. (This unit sits on my desk and connects remotely to a noisy disk array and LTO tape library in another space via installed Fibre Channel and SAS HBAs ). Thermals are great even when this unit is stressed moving a high volume of data from the array to the three drives in the tape library while providing Fibre Channel and iSCSI targets to severl other hosts.

This was my first PC build and this was very easy to setup and is extremely quiet. They included the thermal paste which I didn't even know to expect and also a little noctua badge. My Mini ITX stays pretty cool.

I've used Noctua for years. Like other reviewers said, these screws are too short. So this cooler is useless. And not just a little short, very short, the screws won't even begin to screw on. I've without hesitation bought and recommended Noctua for a long time, but after reading Noctua's responses to others that bought this cooler, i'm going to be cautious from now on and i'm now shopping for a cooler for a client cpu made by anybody other company than Noctua (it needs to fit). With all my experience with Noctua, I'm surprised i just wrote the last sentence. I've built hundreds of computers and used Noctua coolers many times. I don't believe i'm failing to know how to do this. The cooler is simply not compatible because of the screws.

Noctua make among the very best CPU coolers on the market, but man, do I hate that brown and beige color scheme they’re famous for. Thankfully this little beauty is a sexy jet black. I bought this for a budget build in a MATX case, and it works incredibly well at keeping temps well within acceptable range while remaining silent. It’s not keeping temps UNDER range, but in such a tight case I don’t really expect it to. All in all, if you’re looking for a low profile cooler, for price and performance you can’t really beat it.

This is a solid, elegant cooler. For reference, I’m using it on an i5 12400 which is not overclocked.

this fan is awesome its so quiet i dont even hear it at full speed!

C'est mon deuxième, le précédent était pour AM4, même chose sur Lga 1700. Petit format, excellent résultats, merci Noctua !

Best cooler money can buy

This is managing to keep my i5 12600K cool enough ( 70 ish c ) in a mini itx case.
