Noctua has introduced the NH-L9a-AM5 low-profile air cooler. The new product is designed for use in very compact HTPC and Small Form Factor (SFF) PCs based on the latest 65-watt AMD Ryzen 7000 AM5 processors and using the Socket AM5 processor socket.
Noctua in his press release notes that the NH-L9a-AM5 is specifically designed for low-power models of the Ryzen 9 7900, Ryzen 7 7700, and Ryzen 5 7600 processors, which have a nominal and maximum TDP of 65 and 88 watts, respectively. However, in lab tests, the NH-L9a-AM5 was also used to cool the Ryzen 9 7950X and Ryzen 9 7900X up to 130W.
The overall height of the NH-L9a-AM5 is only 37mm. In addition to the aluminum heatsink with heatpipes, the cooler contains a 92mm NF-A9x14 fan. Due to its size, the novelty does not pose any obstacles to installing RAM modules with radiators of any height.
In addition to the regular version of the NH-L9a-AM5 with a natural heatsink and the traditional sand-brown Noctua fan, the manufacturer has also introduced an all-black NH-L9a-AM5 chromax.black model. The company included its proprietary NT-H1 thermal compound with both versions of the cooling system.
The NH-L9a-AM5 cooling systems are compatible with the special NA-FD1 frame kit for the NF-A9x14 fan. These frames mount on top of the fan and allow it to draw fresh air for cooling directly outside of the computer case through the perforated holes in the side panel, and not from around where the air is heated by other PC components. If you wish, you can use more of these frames by increasing the height of the structure by 5-45 mm. According to the manufacturer, the frame is able to increase the cooling efficiency of the NH-L9a-AM5 by another 5 degrees Celsius or more.
The regular NH-L9a-AM5 version costs €50/$45, while the chromax.black version costs €60/$55.
