Noctua NH-L9a-AM4 chromax.Black, Low-Profile CPU Cooler for AMD AM4 (Black)

I recently purchased the Noctua NH-L9a-AM4 chromax.Black Low-Profile CPU Cooler from Amazon. The delivery was speedy and on time, as expected with Amazon Prime.Upon unboxing, I found the cooler to be smaller than I initially expected, especially compared to my previous NH-D15 chromax.black. However, the packaging was excellent, with Noctua including everything needed for installation, such as thermal paste and a backplate.Installation was straightforward and easy. As an IT professional, I found no issues with the process, which involved cleaning the CPU, applying thermal paste, and screwing down the cooler with the provided components.In terms of performance, the cooler works surprisingly well. While I haven't conducted stress tests, it keeps the CPU cool during normal tasks. Initially, the cooler was a bit noisier than expected, but after installing the appropriate drivers and completing startup processes, it became much quieter.The aesthetics of the cooler are impressive. The black design fits seamlessly with the rest of my system, and the low-profile form factor helps reduce the feeling of cramped space inside the case.Overall, I believe the Noctua NH-L9a-AM4 chromax.Black is worth the money and would recommend it to others. I am very satisfied with my purchase and plan to continue using Noctua coolers in my future builds.

First off, this is a fantastic cooler for lower wattage chips, perfect for my 5600x. Love the black aesthetic and cooling performance. Low noise level, quality heat sink, and modular fan if you want to swap fans. The only issue that I find with this cooler, like many others, is the mounting hardware. Not the hardest one I've had to deal with, but it could be a easier, especially if you have to reseat the cooler or swap the cpu. I took several YouTubers advice and installed it upside down. While a minor inconvenience, it still didn't deter me from giving this product 5 stars. What went above and beyond for me was the absolutely excellent presentation and packaging of the product. It shows what a quality company Noctua is and you know what you are getting is premium grade.

I was setting up an ITX system as a secondary in one of my phanteks computer cases, and needed a cooler that could fit in a tight space and still provide adequate cooling for the ITX' processor. Most 120mm AIOs didn't have the tube length I needed, tower coolers were too tall, and a lot of 'low profile' coolers conflicted with the RAM slots.This ended up being the best option for my secondary system, and does an excellent job keeping it cool. Mounting is kind of tricky since you have to flip the motherboard upside down and install it that way, but it wasn't too difficult. And what I liked most was being able to swap out the fan for something with a little bit of color as they included screws for both low-profile fans like the one included, as well as screws for thicker fans such as a Scythe RGB fan I had purchased to go along with the cooler.

NOCTUA, the premier king in CPU fans. This thing is SUPER attractive. have it paired with a 5700g in a SFF ITX case and it was SUPER easy to install. Came with a tube of Noctua's thermal paste and everything needed. was eyeing this one for a while, its super quiet (without the low noise adapter) and its the only fan in this case.very happy with it. have installed many of these (noctua branded fans) on friends builds and looking to replace my NZXT AIO with a 120mm or NH15D Noctua for my main gaming rig.

Great cooler from noctua easy to install and setup. Like the small profile design only issue I have is I’m running a AMD Ryzen 5800x with a Zotac 3050 on a gigabyte a520i motherboard. Case is a itx cooler master nr200 16gb ram 3600mhz, 650 watt power supply. Only problem I’m having is the Cooler can’t keep the CPU under 70c at Home Screen. Under load running ready or not at load screen it got as high as 90c. Also did a test with left for dead 2 and got similar results. So if you are planning on using a 5800x with this cooler. I would not recommend using this one. I’m probably going to look for a beefy water cooler.

Overall, it's a solid investment, and I’m satisfied with my purchase. I’d recommend it as it is a reputable brand and very silent. Performance wise, I still found my Ryzen 7 5700x thermal throttling but that is to be expected from a cooler this size. Packaging was top-notch with a premium unboxing experience. I rate it a solid 4 out of 5 mainly because I do feel I am overpaying very slightly by going Noctua.

Very low profile. I had it installed on a 5600x in a fractual terra case and it kept it very cool. Install was very easy and didn't interfere with the ram sticks at all.I received a 5600x3d for Christmas and challenged this cooler on keeping it cool. I seen it go to 90 degrees c pretty quickly but I did expect the cooler to struggle with this cpu. I installed another noctua cooler that was compatible with the fractual terra and seen Temps that were more acceptable. I'm gonna keep this cooler as I will build another computer in another fractual terra for my wife.

Used this on a mini ITX motherboard in a TINY computer case. This cooler solved all the issues. It does not interfere with full height RAM, is very compact while being very quiet and provides good cooling. It is a down draft cooler that directs air towards the motherboard, which in my circumstance, is an extra benefit because there is no other fan in the case. The CPU is a Ryzen 3 3200G processor with 4 cores. It is not being maxed out at all. The online reviews suggest that it can handle a much higher thermal load than what I’m subjecting it to.
