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

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

Nothing to add, great quality and consumer experience

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.

Was one of the only that had a low enough clearance for my 5 liter sff itx gaming pc. Wish black wasn’t at a price premium, but looks good and is the best performer in its class.

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.

I received the same cooler, from Amazon a few days ago and it was obviously used and returned. Amazon customer service said to return it, and I shipped it back via QR code they supplied.The new cooler is in perfect/new condition and the 5-star rating is both for the product as well as customer service. Thank you.

Virtually silent. But pricey

I like this cooler overall, but I tried mounting it to a GIGABYTE B760I AORUS PRO DDR4 and the screws are too short. I was able to get three of them in, but only a few of the threads are engaged and for the 4th one, i had to find a longer screw somewhere else. I think it's not sitting perfectly flat on the CPU, but it's close enough and I've been using it for a while and it's working fine. I would love this product if the mounting screws were just a millimeter or two longer.
