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

What more is there to say? Every other fan I looked at had reviews comparing the fan to Noctuna fans. Skip the hassle and just buy Noctuna.

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.

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

Amazing low profile cooler. Mine is cooling a Ryzen 5 1600 AF. Low noise levels and exceptional cooling (when gaming roughly 60C , under Cinebench R20 load about 72 C). Im sure that changing the fan out for a larger one would improve temps but I’m happy with it so far.

Works like a charm! Keeps thing very cool, while being very low profile!

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.

Little to no noise level, but hard to mount onto your motherboard.

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

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.

Like how low it sits on the motherboard
