> 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 dayLove the fan, super high quality. The mounting kinda was ridiculous though but Im not sure how to make that better. You have to hold the mounting bracket backplate, fan, and the screw in place all at once. I guess you could temporarily tape the backplate and then remove it after install. But yeah its dead quiet, looks great, and truly is low profile.

> 3 dayI bought this cooler to replace my AIO that was in my SFF build. It is quiet but I do think my CPU runs a bit hotter now, but not a lot. I bought it to match the rest of my noctua fans. I recommend this fan to anyone with a low profile build.

> 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 dayI bought this to go in the absolutely tiny ASRock DESKMINI A300W. This is cooling a Ryzen 3400g.

> 3 dayLooks sleek and slim, very happy with it so far. The fan can get a bit noisy, especially with AMDs fan curve, so I decided to get a 120mm fan and adapter. Should cool and quiet things down for a perfect low-profile cooler

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. |
