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

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.

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.

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.

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.

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.

Super quiet and small great for a mini itx build. That's what I used it for.

Fits perfectly in a Silverstone micro-computer with an Asus 1851 series motherboard.

No spacers are provided and the screws are too short, barely managed to get the first thread of the screw to connect to the fan, went to test to see if it would boot, wouldn't post because getting the screw to connect to the fan destroyed the pins on my Gigabyte B760I Aorus Pro DDR4 Intel LGA 1700 Mini-ITX Motherboard. Maybe if they didn't try to save a few cents on the screws and gave the screws a few more milimeters, this product would actually be good instead of costing you however much it takes to replace your motherboard.
