Proven premium heatsink (more than 100 awards and recommendations from international hardware websites), now available in an all-black design that goes great with many colour schemes and RGB LEDs Only 37mm height allows it to fit compact HTPC and Small Form Factor (SFF) cases, tailored footprint guarantees 100% RAM and PCIe compatibility on all ITX, Micro-ATX and ATX AM5 motherboards Renowned, award-winning NF-A9x14 slim 92mm fan with Low-Noise Adaptor and PWM for automatic speed control: full cooling performance under load, whisper quiet at idle! Thanks to the same proven heatsink design and NF-A9x14 PWM fan, it stays true to the NH-L9a-AM5’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. Please note: The NH-L9a-AM5 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 our CPU compatibility list to find out whether the NH-L9a-AM5 is recommended for your CPU.
