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

Difficult cooler to use, do not use the paste they send.

this small ff cooler packs a punch

On normal day to day use and Gaming, this thing will handle a 5900x just fine. On windows 10 I have power save mode on. This means that all my clock speeds are at 2.1ghz all the time (unless CPU gets a huge work load, then clock speeds will adjust to something higher) even when playing on games.

Looks sleek and slim, very happy with it so far. The fan can get a bit noisy, especially with AMDs fan curve, so I decided to get a 120mm fan and adapter. Should cool and quiet things down for a perfect low-profile cooler

So i got a new small itx case where my AIO is not able to fit. I bought this to cool my Ryzen 2700x and it works great. I play games mostly so cpu isnt intense. Its average is about 45c and ive seen it go as high as 75c during cinebench (cpu bench test). This is basically an open air case with alot of airflow. Im running it with a 3080ti. No issues at all with performance. Definitely recommend. Gpu tops out at 70c while gaming. Fyi. Very low fan noise.

Good quality material but combined with the stock fan the stock AMD wraith cooler can fit almost every application this can and perform 30% better. However, when I hooked up a 120mm fan to this, it outperformed the wraith by 30%.

This cpu cooler is amazing for the size because noctua is amazing, but keep in mind, temps will still get hot.

Somehow cools my 3950x

I bought this cooler to replace my AIO that was in my SFF build. It is quiet but I do think my CPU runs a bit hotter now, but not a lot. I bought it to match the rest of my noctua fans. I recommend this fan to anyone with a low profile build.

This thing sits lower than my ram it’s amazing! Thermals are great and it allowed me to get that clearance I needed to vertically mount my gpu in my ITX case! Super quiet as well easy to install! Worth every penny! (UPDATE 1 MONTH LATER) suddenly got frame rate drops and couldnt understand why so I ran a test and found out my cpu fan wasnt spinning. Low noise adapter that the cooler came with went out but I just used an extender my case manufacturer provided so were all set. Honestly sounds the same in volume still a 5 star for me.
