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

Es muy bonito y silencioso, mantiene el pc fresco

NOCTUA, the premier king in CPU fans. This thing is SUPER attractive. have it paired with a 5700g in a SFF ITX case and it was SUPER easy to install. Came with a tube of Noctua's thermal paste and everything needed. was eyeing this one for a while, its super quiet (without the low noise adapter) and its the only fan in this case.very happy with it. have installed many of these (noctua branded fans) on friends builds and looking to replace my NZXT AIO with a 120mm or NH15D Noctua for my main gaming rig.

I recently purchased the Noctua NH-L9a-AM4 chromax.Black Low-Profile CPU Cooler from Amazon. The delivery was speedy and on time, as expected with Amazon Prime.Upon unboxing, I found the cooler to be smaller than I initially expected, especially compared to my previous NH-D15 chromax.black. However, the packaging was excellent, with Noctua including everything needed for installation, such as thermal paste and a backplate.Installation was straightforward and easy. As an IT professional, I found no issues with the process, which involved cleaning the CPU, applying thermal paste, and screwing down the cooler with the provided components.In terms of performance, the cooler works surprisingly well. While I haven't conducted stress tests, it keeps the CPU cool during normal tasks. Initially, the cooler was a bit noisier than expected, but after installing the appropriate drivers and completing startup processes, it became much quieter.The aesthetics of the cooler are impressive. The black design fits seamlessly with the rest of my system, and the low-profile form factor helps reduce the feeling of cramped space inside the case.Overall, I believe the Noctua NH-L9a-AM4 chromax.Black is worth the money and would recommend it to others. I am very satisfied with my purchase and plan to continue using Noctua coolers in my future builds.

I put this on a Ryzen 7 5800x3d in a fractal ridge ITX build. In game was ok but it seemed that heat would get trapped and slowly crawl until i had a constant 91c and still crawling up. Taking the side plate off reduced Temps immediately and I was disappointed I had to use it that way. I did some research and I got the Noctua na-fd1 fan duct kit which made sure the fan only pulled air from outside of the case and the highest temp I've had so far was 85c with average Temps in the mid 70's and no crawling. I'm very happy with Noctua. Now I can play my games without worry.

I was excited to try this low profile CPU cooler in one of my PC builds. This was going into an AMD Ryzen 5700X system. While the thermals of the CPU were within spec, I was a little disappointed with the noise level. I don't play many games, but the fan speed would spin up to full power when the system was idle. It was a noticeable noise level. There are always tradeoffs. If the case this is installed in needs low profile you cannot beat the Noctua brand and performance, but you will hear the fan.

Overall, it's a solid investment, and I’m satisfied with my purchase. I’d recommend it as it is a reputable brand and very silent. Performance wise, I still found my Ryzen 7 5700x thermal throttling but that is to be expected from a cooler this size. Packaging was top-notch with a premium unboxing experience. I rate it a solid 4 out of 5 mainly because I do feel I am overpaying very slightly by going Noctua.

Great cooler from noctua easy to install and setup. Like the small profile design only issue I have is I’m running a AMD Ryzen 5800x with a Zotac 3050 on a gigabyte a520i motherboard. Case is a itx cooler master nr200 16gb ram 3600mhz, 650 watt power supply. Only problem I’m having is the Cooler can’t keep the CPU under 70c at Home Screen. Under load running ready or not at load screen it got as high as 90c. Also did a test with left for dead 2 and got similar results. So if you are planning on using a 5800x with this cooler. I would not recommend using this one. I’m probably going to look for a beefy water cooler.

Very low profile. I had it installed on a 5600x in a fractual terra case and it kept it very cool. Install was very easy and didn't interfere with the ram sticks at all.I received a 5600x3d for Christmas and challenged this cooler on keeping it cool. I seen it go to 90 degrees c pretty quickly but I did expect the cooler to struggle with this cpu. I installed another noctua cooler that was compatible with the fractual terra and seen Temps that were more acceptable. I'm gonna keep this cooler as I will build another computer in another fractual terra for my wife.
