> 3 daySeriously: Best. Tiny. CPU. Cooler. Ever. Gives you the most bang for your buck, its so quiet (I could barely tell my system was running on load), and the new Chromax.black looks so good. Only thing that was awkward about it was installing the back plate under the board and having to screw in from underneath instead of on top like most of the others, but all-in-all, really cant complain after seeing these thermals. Cant get this kind of performance at this size from anyone else. Also, the box they sent it in was adorable, not that it matters for most people, but you can really tell they care about their consumer base.

> 3 dayGot this one because I wanted a low profile cooler for purely aesthetic reasons and this one is an incredible deal. Installed this on my MSI B550 (I saw a review that said it lacked parts needed to fit but it seems it’s all pre packaged now) able to overclock my Ryzen 5000 series CPU and the temps are low. Very silent and was easy to install. Everything from product to packaging is incredible. My first time purchasing a noctua product and it really impressed me.

> 3 dayGreat CPU cooler! Great build quality. Always been a fan of Noctua and I’ve gone with this cooler in so many other SSF builds of mine and my most recent one was in an In Win Chopin cools the CPU perfectly. It’s also about the same size as Low Profile sticks of ram so they should fit in every case possible. Apart from that, they’re Noctua and this is an amazing product. Highly recommend.

> 3 dayGreat cooler used for a micro PC build. Fan is so quiet I had to check for air flow to make sure it was running! I will definitely be buying more Noctua fans and coolers in the future. Awesome equipment Noctua!

> 3 daythe l9a needs no introduction, if youre looking for a cooler of this size, its impossible to beat. its a little pricy for the cooling it offers, but its quiet and keeps my ryzen 5 3600 nice and cool.

> 3 dayWhen I purchased this cooler, I didnt realize that my motherboard had a non-standard component arrangement which would prevent the included backplate of this cooler from fitting. Noctuas support has been fantastic and they shipped me an alternative mounting solution free of charge.

The NH-L9a-AM4 chromax.black is an all-black version of Noctua’s award-winning NH-L9a-AM4 low-profile quiet CPU cooler for AMD Ryzen based HTPCs and Small Form Factor (SFF) builds. Thanks to the same proven heatsink design and NF-A9x14 PWM fan, it stays true to the NH-L9a-AM4’s successful formula of fusing a height of only 37mm with strong performance and excellent quietness of operation, as well as 100% RAM and PCIe compatibility. At the same time, the chromax.black version with its black fan and black coated heatsink combines these assets with a sleek stealth look. Topped off with the renowned SecuFirm2 low-profile mounting system for AMD AM4 and Noctua’s enthusiast-grade NT-H1 thermal compound, the NH-L9a-AM4 chromax.black is a premium choice for customers who seek an ultra-compact heatsink that looks just as great as it cools.

|---|---|---|---|
37mm low profileDue 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 compatibilityThe 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-ITXSome 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. |
Custom-designed SecuFirm2 mounting for AM4The NH-L9a-AM4 comes with a custom-designed SecuFirm2 mounting system for the AM4 socket of AMD’s Ryzen platform. Allowing the heatsink to be fixed from the back of the motherboard, it makes installation easier than ever, all while maintaining the trusted SecuFirm2 quality. |
