Noctua today introduced another addition to its chromax line of all-black CPU coolers: the new NH-L9a-AM4 chromax.black is a low-profile quiet CPU cooler for AMD’s Ryzen-based HTPCs and Small Form Factor (SFF) builds.

Thanks to the same heatsink design and NF-A9x14 PWM fan as the original NH-L9a-AM4, it stays true to the same successful formula of fusing a height of only 37mm with strong performance and quiet operation, as well as 100% RAM and PCIe compatibility.

The NH-L9a-AM4 is a popular, low-profile coolers for AMD Ryzen CPUs and APUs such as the 3700X, 3600, 3400G or 3200G. Due to its slim 23mm heatsink and the NF-A9x14 low-profile fan that measures only 14mm in thickness, the cooler 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. Thanks to its compact footprint that fully complies with the socket keep-out zones specified by AMD, neither the heatsink nor the fan overhang the RAM, so the cooler provides easy access to the slots and is compatible with tall memory modules.

The new chromax.black version is featuring a black coated heatsink, a black fan with black anti-vibration-pads, black fan screws and black mounting parts.

It features the SecuFirm2 low-profile mounting system for AMD AM4, comes with Noctua’s NT-H1 thermal compound and is backed by a 6-year manufacturer’s warranty.

The manufacturer’s suggested retail price is EUR/USD 49.90.
