The NH-L9a-AM4 is the latest, AM4-specific revision of Noctua's award-winning NH-L9a low-profile CPU cooler for AMD Ryzen-based HTPCs and Small Form Factor (SFF) systems. At a height of only 37mm, the NH-L9a is ideal for extremely slim cases and, due to its small footprint, it provides 100% RAM and PCIe compatibility as well as easy access to near-... moresocket connectors even on tightly packed mini-ITX motherboards. The custom-designed SecuFirm2™ mounting system for the AM4 socket makes installation child's play and, thanks to the highly optimised NF-A9x14 92mm fan that supports fully automatic speed control via PWM, the NH-L9a-AM4 runs remarkably quietly. Topped off with Noctua's renowned NT-H1 thermal compound, the NH-L9a-AM4 combines everything users have come to expect from Noctua's larger coolers into a super-compact, premium-quality package for ITX and HTPC builds with Ryzen CPUs or APUs.Features:New revision for Ryzen's AM4 socket:- Since the original NH-L9a for AM2(+), AM3(+), FM1 and FM2(+) has received more than 50 awards and recommendations from international hardware websites and magazines, the new AM4 revision builds on the same proven heatsink design to provide excellent low-profile cooling performance for Ryzen CPUs and APUs.37mm low profile:- Due to the slim 23mm heatsink and the NF-A9x14 PWM low-profile fan that measures only 14mm in thickness, the NH-L9a-AM4 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.100% RAM compatibility:- The NH-L9a-AM4 has a compact footprint that fully complies with the socket keep-out zones specified by AMD. This means that neither the heatsink nor the fan overhang the RAM, so the cooler provides easy access to the slots and is fully compatible with tall memory modules.Low-Noise Adaptor:- Allowing the maximum speed of the NF-A9x14 PWM fan to be reduced from 2500 to 1800rpm, the included Low-Noise Adaptor (LNA) makes it possible to achieve near-silent setups using CPUs with less than 65W TDP.Custom-designed SecuFirm2™ mounting for AM4:- The NH-L9a-AM4 comes with a custom-designed SecuFirm2™ mounting system for the AM4 socket of AMD's Ryzen platform. Allowing the heatsink to be fixed from the back of the motherboard, it makes installation easier than ever, all while maintaining the trusted SecuFirm2™ quality. Caution: - 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 is only recommended for CPUs/APUs with up to 95W TDP (Thermal Design Power). Please consult our TDP guidelines to find out whether the NH-L9a-AM4 is recommended for your CPU/APU.Specifications:Cooler Specifications: - Socket compatibility: AM4- Dimensions without NF-A9x14 PWM: 114x92x23 mm- Dimensions with NF-A9x14 PWM: 114x92x37 mm- Weight: 390 gr- Weight with NF-A9x14
