> 3 dayNot the coolest temperature but what do you expect? It is small. My gaming system does not overheat with this even though mounted to limited space.

> 3 dayGreat cooler outperforms similar-sized coolers with higher specs. Great mounting system, quality manufacturing. Great for CPUs with 65w TDP in SFF builds.

> 3 daySame great performance I was getting from my old NH-L9a-AM4, but black. Looks very nice in my S4M.

Greater than one weekIm using the cooler in a small computer installation where quiet operation of this component is very important.

> 3 dayExcellent cooler. Im so glad I purchased this. I thought I was going to need to buy some thermal paste but noctua actually included a LARGE tube of thermal paste. Excellent!!! Easy installation, cool temps, and the black looks nice!

> 3 daySystem: Gigabyte X570 I Aorus Pro, AMD Ryzen 5 5600g, 32gb G-skill Ripsaw Ram 2400Mhz, 500 gig PNY SSD and 1T WD SSD. Ram at advertised 2400Mhz and cpu over clocked at 4ghz. Heat problems right off the get start. Turned ram down to 2133 and cpu to stock 3.9 and heat problems still, exchanged out with stock heat sink and fan, turn ram back up to advertised and over clocked the cpu and no more heat problems. Gave 2 stars because the Noctua NH-L9a-AM4 chromax Black, Low-Profile CPU Cooler for AMD AM4 just would not do the job. Made from great materials. I will save for my next build which is going to be an F2+ socket, AMD 6800k down to a mini itx case. Ill update if it keeps that one cool.

> 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.

Greater than one weekLowered 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.
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. |
