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

Great product, it knocked my CPU temperature down 20 degrees C vs. my stock ryzen wraith. I only took a star off because it is very difficult to install without removing your motherboard. For a new build it would be easy but if you are upgrading it will be a challenge. Also there are no extra screws so if one rolls off somewhere you might be in for trouble.

No other low profile cooler has better temps than Noctua coolers. This is my second one on a different build and its always 30-35c at idle with probably the smallest case Ive ever housed a PC in.

I bought this to replace a tower-style cooler that didnt fit well with my updated RAM. Installation is straight forward and simple if your board is not installed in the case. On-case installation (like mine) is a little trickier as you need to use the backplate provided and do the adjustments vertically. In terms of performance, I have no complaints, it performs as good as my old cooler in a significantly smaller package, which is definitely a highlight. Probably the major drawback is the price, but in my opinion is worth it

Super quite. Way nicer than the stock AMD coolers

As it says on the tin. Installation was super easy, and the fan is powerful but barely audible. When at full blast, the noise is soft, so its not annoying and its easily drowned out by your games or movies.

This is a great cpu cooler that is quiet and low profile. This is cooling my Ryzen 7 3700X and keeping the temperatures steady and ideal. I would like to see a newer method by Noctua for mounting this type of cooler. Having to secure the unit from underneath is doable just takes some coordination. Overall the device is great and works flawless. I would like to see some option for a fan RGB. This is an excellent purchase for those who may be building an ITX system also. Noctua gets my vote for Quality and Performance.

Lowered my temperatures right away, from 42 idle on stock cooler to 36C on my Ryzen 5 5600G and while gaming my temps went down from 86C to 69C, it would be even lower if I hadn’t decided to keep the build in a tight space.

Same great performance I was getting from my old NH-L9a-AM4, but black. Looks very nice in my S4M.

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

so i bought this cpu fan cause i wanted small fan so i can install my gpu vertically .i have a Gigabyte B550 aorus Elite with Ryzen 7 3700x on Noctua website this cpu is compatible for this fan.before had a Cooler Master Hyper 212 Black Edition but since the size of this cooler i could not install my gpu vertically.so first to install Noctua NH-L9a-AM4 on a already built system is a pain much easier if you have the motherboard out.now cooling 7 3700x stock my temps were to high not happy.would run a few test and it would go up to 95 plus Celsius with the Hyper i get 70-75 Celsius but the hyper gets loud the Noctua is pretty quite at full full speed but this cooler can handle the heat the Ryzen 7 3700x generates so i had to return it and when back to the Hyper looking to try AIO cooler instead.this should work with lower power ryzen just fine.also this cooler is small fit my motherboard perfect does not take much space so ram and gpus dont get in the way.
