Noctua NH-L9a-AM4, Premium Low-Profile CPU Cooler for AMD AM4 (Brown)

One of the best low profile coolers on the market. Great for mini-itx builds if space is an issue. Under heavy load (gaming) it keeps my CPU under 70 celsius

I've been using this cooler for 5 years in my current sff build and have had absolutely no issues. Really great cooler. No issues with installation or mounting across multiple cases and of course the size is a major plus.

Keeps my Ryzen 5 cpu cool and quiet under load. Great build quality.

El enfriador es de buena calidad tanto en la construcción del disipador como en el ventilador, aunque se desearia que alcanzara mayor numero de revoluciones.Incluye pasta térmica suficiente para dos procesadores, el backplate para la tarjeta madre, buenos tornillos grandes y resistentes, insignia glamourosa de Noctua para presumir su caja de PC y un adaptador de bajo ruido NA-RC7 que su función real es disminuir el número de revoluciones para que disminuya el ruido producido, aunque no lo necesita porque el ventilador es silencioso.Estimo que la caja, empaque, manual de instrucciones, etc es demasiado lujosa y costosa para el contenido, lo cual implica un sobrecosto para el consumidor y que se irá a la basura a contaminar el planeta.

Will it fit?This is obviously a very low profile cooler. But please do check out the dimensions. It fit even on my mini-ITX motherboard (that's TINY), but do have some oversight with how things are spaced on your motherboard. The heatsink is short, but fairly spread out.Temperature talk/overclocking:Firstly, let me address something at least I was concerned with while I was researching this. YES, you can lightly overclock your APU while using this, just test stuff out until you find something that works. And please do be careful, your computer is a sacred baby, go easy on it. Anyway, for example, I overclocked my Ryzen 3200g CPU to 4000mhz, and my GPU to 1500mhz. At least in games I play (GMOD at 1080p full settings, Payday 2 1080p medium), I get 60fps while also staying around 55 degrees Celcius. That's about 30 degrees BELOW what would be considered ALMOST dangerous for an APU.But what about idle/light workloads for non-gamers? IdleNoise and the noise adapter:The fan is much more quiet than any stock AMD cooler, and although it can be made even more quiet with the noise adapter, that's because the adapter slows the fan down. In essence, the adapter WILL affect cooling performance, but most often that's not even necessary. The fan is very quiet and cool on idle or with light workspace stuff.Installation:Installation is easily the only "flaw" this cooler had in my case (even then I still gave it five stars). To install it, I recommend taking the fan off the heatsink, place the heatsink upside down atop a well balanced, sturdy cylindrical object. Apply thermal paste to your CPU (or APU ; ) ), then with your motherboard upside down, line up the heatsink holes with the holes on your motherboard. Keep your motherboard pressed down and balanced on the heatsink. Then take that metal plate included and put the PLASTIC side on your motherboard's bottom. Keep it balanced, and lightly screw it in the with "cross" method. Once the heatsink is secure, flip your motherboard. Not which direction the fan blows the air. You can screw the fan back into the heatsink so that it will blow the majority of air where you want it to.Now, clearly, that's much more complicated, and arguably more risky than a standard installation. But with patience, top-of-the-line thermal paste, and some luck, it will be so worth it.Appearance:People say Noctua fans are ugly, but there's a charming, almost nostalgic look to the fan. It will hardly match any color scheme at all (for instance, mine is red and black, and this fan looks like the nerdy kid at a party), but there's an eccentric, signature feel to that.Extras:You get some extra fan screws and a cool little metal Noctua pin. This looks quite nice and adds character to a PC case. Mine is proudly located above my Ryzen 3 and Vega Graphics stickers.

-This is a review for Noctua NH-L9a-AM4My Experience: installation was pretty simple, apply the included thermal paste, which is a nice added bonus, flip your motherboard around and stack your motherboard on top of the cooler, place the backplate on the motherboard and screw in, it's about as simple as it gets when installing a cooler and really did not take me longer than 10 minutes. When you open the box you get a real premium feel with a small thank you letter, a small metal logo with adhesive on the back, the screws, and the paste, even includes a little adapter of some sort and the manual of course. I'm running a Velka 5 revision 1.1 and it manages to fit into my case extremely easily and I was able to have enough space between the fan and the side panel to put in a 2.5 SSD, with that option being impossible with the included Ryzen 5 3600's cooler with the shroud taken off, actually if you look at my pictures you can see I posted one with the two of them right next to each other, again the Ryzen's cooler having the shroud taken off. Unfortunately noise and size are the only thing this cooler has going for it, idle the temps of my Ryzen 5 3600 are around the high 50s and low 60s on idle and while doing any kind of gaming it can go up as high as the low 80s and that's with no overclock. Speaking of noise it's very quiet, the only fan I can hear from my computer would be the fan of my Vega 56 blower style cooler, which you can imagine would be quite loud.Positive:+ Able to fit in my case really easily+ Installation was really simple+ Included thermal paste that you can easily store for future use+ Packaging is top notch and really gives it a premium feel+ Very quiet+ Includes a cute little metal logo with adhesive on the back to apply to your caseNeutral:| The color of the fan, however there's always the black fan model you can go forNegative:- Expect little to no overclocking to be done on your CPU with this coolerRecommended: Definitely recommended if you are running a small form factor PC
