Greater than one weekNoctua always makes good product, but for some reason my package was opened. That is some sketchy business if you ask me. What if it was something valuable? Good thing the average Joe doesnt know wtf this thing is....

> 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.

08-06-2025This seemed quite difficult to install with only one person. Required to screw down the heatsink on while screwing in the bracket on the backside of the motherboard. It does work well and cool well in my case though, it is extremely low profile.

Greater than one weekNot 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 dayI use this in my Ncase M1 (glass panels) on my AMD Ryzen 7 3800X. Averages around 43 C and tops out at 70C. This is very impressive considering it is currently 90+F weather and inside my house is at an average temp of 85F
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. |
