> 3 dayGreat product, it knocked my CPU temperature down 20 degrees C vs. my stock ryzen wraith. I only took a star off because it is very difficult to install without removing your motherboard. For a new build it would be easy but if you are upgrading it will be a challenge. Also there are no extra screws so if one rolls off somewhere you might be in for trouble.

> 3 dayThrew this in my asrock x300 to cool my ryzen pro 4750g and its quiet and handles temps very well even when you adjust fan speed. My dvr/emulator station loves this in it

> 3 dayThis 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.

> 3 dayNot very far off in temps as the cryorig c7 it replaced but its way quiet. Cant hear it under load with my Ryzen 2600

> 3 dayThis is a great cpu cooler that is quiet and low profile. This is cooling my Ryzen 7 3700X and keeping the temperatures steady and ideal. I would like to see a newer method by Noctua for mounting this type of cooler. Having to secure the unit from underneath is doable just takes some coordination. Overall the device is great and works flawless. I would like to see some option for a fan RGB. This is an excellent purchase for those who may be building an ITX system also. Noctua gets my vote for Quality and Performance.

Greater than one weekEDIT as of 3/26/2020: I ended up returning this cooler and going with a different cooling solution. The idle and load temps in my case (Thermaltake core v1) were far too high for my liking after a burn in period. This cooler has a MAX of 65W TDP and Noctua is serious about it. Despite the temps, this cooler is very quiet, and I am not knocking any stars as it looks great and would do a great job on a less intensive CPU, like a Ryzen 3 or similar.

> 3 dayReally great product. Needed a cooler for my Ryzen processor in my M-ITX build. Extremely tight case (Silverstone SG13) so I needed something with low clearance. This fit the bill and is nearly silent to boot. Will always recommend Noctua products.

> 3 dayIm using the cooler in a small computer installation where quiet operation of this component is very important.
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. |
