Noctua NH-L9a-AM5, Premium Low-Profile CPU Cooler for AMD AM5 (Brown)

I am using this cooler with an AMD 7900X CPU. Performance wise, it seems to be doing an excellent job. I do not overclock so I am certain I am not stress testing the maximum cooling abilities. However, for my needs, this CPU cooler fan work quite well. It is quiet during normal operation.My only issue came during installation. It was initially unclear to me how this fan mounts since the AM5 socket had threaded inserts. The provided screws did not go into the inserts but then I noticed smaller, longer screws that fed through the threaded inserts. That allowed to me to attach the cooler perfectly.I am quite satisfied with my purchase.

Mounted in 2U Rack Choice case on an Asrock B650M Pro RS motherboard with AMD Ryzen 9 7900 chip. Plenty of air. Comes with thermal paste and allen key.

I've got this cooling a r9 7900, in a very SFF case, and it does beautifully. Even under full load, the noise is perfectly acceptable. General use, it is whisper quiet. To be expected of Noctua cooling solutions. One of the best, if not the best, low profile coolers on the market.

It has very good temps and it’s super quite but it was a pain to install because you have to flip it over then screw it in from behind

Noctua es noctua. No lo duden.

I have always been a big Noctua fan. Great company, great product. My one beef with this is that the mounting is awkward and I had to take apart my whole computer to get it in. Works great.

Got this for a Small Form Factor PC, using a AUDHEID K7 8 Bay NAS Case, 7700X CPU, and Asus B650M-Plus motherboard. CPU constantly ran hot and throttled itself even when doing simple tasks, never using more than 25% CPU utilization. Tried running it with the top off to see if the case was limited on airflow, same exact results. Switched to a full copper-core from Thermalright with same dimensions. Results were it running consistently 10 degrees cooler no matter the load. This may be fine for lower clock rate CPUs, but I wouldn't recommend it for high performance in tight environments.It did do it's job of cooling the CPU, feels well built, and had great tooling included. Installation was a bit tricky and easier with a second person to hold the motherboard, but nothing crazy. Will buy from them again if the use case fits.

Fits perfectly in my In Win Chopin case. Using this model on AMD 5700G and 7900 CPUs. So far has kept both cool enough to have never shut down. Very quiet, even under stress. Have both cases sitting on the desk right beside the monitors and rarely notice any noise.
