> 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 daySo i got a new small itx case where my AIO is not able to fit. I bought this to cool my Ryzen 2700x and it works great. I play games mostly so cpu isnt intense. Its average is about 45c and ive seen it go as high as 75c during cinebench (cpu bench test). This is basically an open air case with alot of airflow. Im running it with a 3080ti. No issues at all with performance. Definitely recommend. Gpu tops out at 70c while gaming. Fyi. Very low fan noise.

> 3 dayMy own experience: I had a loud small PC, it had the AMD stock cooler for Ryzen 3400G and it was loud along with the Silverstone flex ATX, once I got this CPU cooler half the noise went away and by half, meant no more noise from CPU cooling, just from the power supply!

> 3 daysuper easy to install, super quiet cooling. I used it on a 3400g in a tiny pc and it did a fantastic job cooling that chip. Having tried a lot of Noctuas and other coolers over the years, you really cant ever go wrong buying a Noctua.

> 3 dayI was setting up an ITX system as a secondary in one of my phanteks computer cases, and needed a cooler that could fit in a tight space and still provide adequate cooling for the ITX processor. Most 120mm AIOs didnt have the tube length I needed, tower coolers were too tall, and a lot of low profile coolers conflicted with the RAM slots.

> 3 dayThis cpu cooler is amazing for the size because noctua is amazing, but keep in mind, temps will still get hot.
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. |
