Description
The NH-L9a-AM4 is NOCTUA’s latest low-profile CPU cooler designed for AMD’s AM4 Ryzen platform. Based on NH-L9 CPU cooler for SFF and HTPC systems. Only 37mm high it is suitable for extremely slim cases. With its narrow design it clears RAM and PCIe sockets and allows easy access to near-socket connectors even on Mini-ITX motherboards. With its NF-A9x14 92mm fan with PWM control it is whisper-quiet. In addition with NOCTUA’s NT-H1 thermal compound it is the best choice for low power ITX system builds with Ryzen CPUs or APUs.
NOTE: The NH-L9a-AM4 is a highly compact, quiet low-profile cooler designed for use in small form factor cases and HTPC environments. While it provides first-rate performance in its class, it is not suitable for overclocking and or CPUs that create high heat loads. Please consult manufacturer’s CPU compatibility list to find out whether the NH-L9a-AM4 is recommended for your CPU/APU.
