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

the l9a needs no introduction, if youre looking for a cooler of this size, its impossible to beat. its a little pricy for the cooling it offers, but its quiet and keeps my ryzen 5 3600 nice and cool.

even a 6 core CPU will struggle with this air cooler. My 3600X would frequently overheat with this cooler causing my PC to randomly crash when doing anything other than web browsing or watching movies.

Great quality.

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.

Love this cooler

This is my first noctua product and I’m very impressed with build quality and packaging. Used this on b550i rig strix mobo in a nr200p case

Awesome fan, but they should have a compatibility chart on each cpu cooler.

Awesome product, looks great and is silent in my 250D.

This is not quiet by any means. Yes its silent at 20%, but at 40-50% its already very loud, and at full speed.. lets say its worse. In addition, its very hard to install, because the cooler and the backplate have to be kept together when you put the screws, which go from the bottom up. You cant install one first and then the other. So I ended up making a sandwich with the cooler upside down, then the motherboard on top of it (fortunately its a mini itx), then the backplate, and with luck I got the screws in. Cooling is pretty bad too, at 50% fan speed and full load for a 65W cpu I have 70-71C, which is far more than I ever had with air cooling, but sure, its well within range of operating temperature.

Great except I got the wrong one. Need itx. I would get a new one if Amazon would hurry up and refund me the money already
