## Overview

The Noctua NH-L9a-AM4 is a premium, ultra-low profile CPU cooler designed specifically for AMD AM4 sockets. At just 37mm tall, it fits perfectly in slim HTPC and mini-ITX cases without compromising RAM or PCIe compatibility. Equipped with a quiet NF-A9x14 fan delivering 57.5 m³/h airflow at only 23.6 dB, it ensures efficient cooling with minimal noise. The package includes award-winning NT-H1 thermal paste and an easy-to-install SecuFirm2 mounting system, backed by a 6-year warranty. Ideal for Ryzen CPUs and APUs with moderate heat loads, it supports light overclocking while maintaining safe temperatures.

## Description

Product description The NH-L9a-AM4 is the latest, AM4-specific revision of Noctua’s award-winning NH-L9a low-profile CPU cooler for AMD Ryzen-based HTPCs and Small Form Factor (SFF) systems. At a height of only 37mm, the NH-L9a is ideal for extremely slim cases and, due to its small footprint, it provides 100% RAM and PCIe compatibility as well as easy access to near-socket connectors even on tightly packed mini-ITX motherboards. The custom-designed SecuFirm2 mounting system for the AM4 socket makes installation child’s play and, thanks to the highly optimised NF-A9x14 92mm fan that supports fully automatic speed control via PWM, the NH-L9a-AM4 runs remarkably quietly. Topped off with Noctua’s renowned NT-H1 thermal compound, the NH-L9a-AM4 combines everything users have come to expect from Noctua’s larger coolers into a super-compact, premium-quality package for ITX and HTPC builds with Ryzen CPUs or APUs. 37mm low profile Due to the slim 23mm heatsink and the NF-A9x14 low profile fan that measures only 14mm in thickness, the NH-L9 stands a mere 37mm tall, which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers. 100% RAM compatibility The NH-L9a-AM4 has a compact footprint that fully complies with the socket keep-out zones specified by AMD. This means that neither the heatsink nor the fan overhang the RAM, so the cooler provides easy access to the slots and is fully compatible with tall memory modules. 100% compatibility with PCIe cards on mini-ITX Some AMD-based mini-ITX motherboards have the PCIe slot located close to the CPU socket zone. While larger coolers that exceed this zone may block the PCIe slot, the compact-sized NH-L9a-AM4 provides full compatibility with PCIe cards. NF-A9x14 PWM premium fan The highly optimised, award-winning NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9a-AM4 to stay remarkably quiet.

Review: Perfect for an APU build. But hear me out. I have some details that may help you. - 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? Idle Noise 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.
Review: Super quiet and fits around components great. Kind of annoying to install. - Used this to replace the AMD supplied cooler in a small home media server. Seems to keep the CPU p,entry cool, but it is only a 65W AMD CPU. Pros: Super quiet. At the speed it normally runs I can’t even hear it and barely noticeable even at full speed. Low profile, plenty of clearance with the top of the case in this small server case. Plenty of cooling for this CPU and could probably handle COUs in the 125 watt range just fine as well. Cons: Nothing major but kind of awkward to install. You need to take the mother board out of the case since unlike other AMD coolers which mount from the top (though the stealth wraith that came with the COU dies need a new bottom plate under the mother board. This one screws in from the bottom. Not a big deal, especially if you’re just building things anyway. Unlike most coolers I’ve used, this one comes with a tube of heat transfer compound you need to apply rather than pre-applied to the cooler. Again, not a big deal, just something to be aware of. Overall, I like it and plan to buy another one for another server I’m building.

### ⭐⭐⭐⭐⭐ Small cooler for small environment
*by D***N on October 20, 2020*

I bought this cooler to put on an ASRock X300W who's max CPU cooler height is 46mm and I was not thrilled about the stock cooler included with the X300 series and the AMD Ryzen 5 3400G Wraith Spire does not fit in this case. The Noctua comes in at about 36mm with a 14mm x 92mm x 92mm fan. Installation was a cinch, or should have been, but managing the back plate (under the cpu) and installing the thermal paste and the cooler was a bit of a challenge, but that was because of the design of the X300W, not the fault of the Noctua. You have to remove the motherboard from the case tray (it has no access to the back of the CPU, underside of the motherboard otherwise). The plate does not hold on without screws, so you have to install the thermal paste, then the cooler (lining up the screw holes as best you can by sight, I did pretty good first try), then turn over the X300 motherboard and use the included screws to attach the heat sink through the back plate while holding the heat sink in place and the motherboard (to keep from shifting). I did it first try, but then I'm experienced, so just keep that in mind if you are using this on an X300 or X300W. Cooling performance isn't bad at all. Using Prime95, Small FFTs, and AVX2 Disabled, the temp normalized around 70.1* C, the cooling fan was turning about 2300RPMs and was whisper quiet. I also did a test with Furmark, 1280x720 for the on board Vega 11 graphics, and the Noctua kept the temps to around 50* C. So effective cooling solution for the size, quiet, and idle temps were about high 30s (37* C) with ambient temps around 81* F. This machine is going to be used for everyday tasks like web surfing, listening to music, watching movies/videos, and playing some games that don't require a beefy rig/processor, like Minecraft, old games from GOG, dosbox, Diablo 2, Starcraft and this cooler seems to be handling it just fine. Would buy this again for tight case designs.
