Noctua announced the launch of new heatsink, the NH-L9a-AM4, which as its own name already summarizes, is nothing more than the NH-L9 (launched in 2012) but only designed for the AM4 socket (AMD Ryzen) and that has received a treatment so that the aluminum radiator and copper heatpipes arrive completely in black color next to a matching fan to improve the appearance.

We find a small heatsink 37 mm high and compatible with any RAM module consisting of a dense aluminum radiator crossed by two copper heatpipes 6 mm thick and all cooled by an NF-A9x14 HS- fan PWM , which is capable of rotating between 600 and 2500 RPM generating a high static pressure of up to 2.11 mmH2O with a loudness of 23.6 dBA, and a useful life of at least 150,000 hours before presenting any problem.

The information of the Noctua NH-L9a-AM4 is completed with the Black SecuFirm2 mounting system , the Noctua NT-H1 high quality thermal compound , an LNA adapter, and goes on sale at a recommended price of 49.90 euros with 6 year warranty.
