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

Threw this in my asrock x300 to cool my ryzen pro 4750g and its quiet and handles temps very well even when you adjust fan speed. My dvr/emulator station loves this in it

Very nice little cooler. Hard to mount but NBD.

So far so good. Got a sff case and the temps are still pretty low.

EDIT as of 3/26/2020: I ended up returning this cooler and going with a different cooling solution. The idle and load temps in my case (Thermaltake core v1) were far too high for my liking after a burn in period. This cooler has a MAX of 65W TDP and Noctua is serious about it. Despite the temps, this cooler is very quiet, and I am not knocking any stars as it looks great and would do a great job on a less intensive CPU, like a Ryzen 3 or similar.

System: Gigabyte X570 I Aorus Pro, AMD Ryzen 5 5600g, 32gb G-skill Ripsaw Ram 2400Mhz, 500 gig PNY SSD and 1T WD SSD. Ram at advertised 2400Mhz and cpu over clocked at 4ghz. Heat problems right off the get start. Turned ram down to 2133 and cpu to stock 3.9 and heat problems still, exchanged out with stock heat sink and fan, turn ram back up to advertised and over clocked the cpu and no more heat problems. Gave 2 stars because the Noctua NH-L9a-AM4 chromax Black, Low-Profile CPU Cooler for AMD AM4 just would not do the job. Made from great materials. I will save for my next build which is going to be an F2+ socket, AMD 6800k down to a mini itx case. Ill update if it keeps that one cool.

Seriously: Best. Tiny. CPU. Cooler. Ever. Gives you the most bang for your buck, its so quiet (I could barely tell my system was running on load), and the new Chromax.black looks so good. Only thing that was awkward about it was installing the back plate under the board and having to screw in from underneath instead of on top like most of the others, but all-in-all, really cant complain after seeing these thermals. Cant get this kind of performance at this size from anyone else. Also, the box they sent it in was adorable, not that it matters for most people, but you can really tell they care about their consumer base.

Only con was the mounting. Trying to sandwich the backplate to the cooler for an even application to the cpu was the biggest pain, but not overly frustrating. Temps are good, not groundbreaking, but acceptable for a low profile cooler. Adjust the curve in your bios to an acceptable noise level and keep it there. Overall I’m very happy.

Works perfectly on my AMD Radeon 9 5900x 12-core porcessor. Highest temperature Ive seen is 90C.

Stock Wraith Stealth cooler for my 2600 was making a whining noise so I had to swap it out. Heard a lot of positive talk about Noctua so I decided to give em a go now that theyre making black fans. Threw this thing in my system and I dont even realize its there. Thing is DEAD SILENT, and cools better than the stock Stealth. Between this and the dual 120mm Noctuas I also mounted in the case itself, the loudest thing now is the power supply. Would throw a Noctua fan in there too if I could. These things command a bit of a price premium, but youre getting exactly what youre paying for: computing tranquility.

Very quiet and it was easy to install. I like the low profile.
