The NH-L9i-17xx is the latest, LGA1700-specific revision of Noctua’s award-winning NH-L9i low-profile CPU cooler for Intel-LGA17xx based HTPCs and Small Form Factor (SFF) systems. At a height of only 37mm, the NH-L9i 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-socket connectors even on tightly packed mini-ITX motherboards. The custom-designed SecuFirm2 mounting system for the LGA1700 (LGA17xx family) socket makes installation a breeze and, thanks to the highly optimised NF-A9x14 92mm fan that supports fully automatic speed control via PWM, the NH-L9i-17xx runs remarkably quietly. Topped off with Noctua’s renowned NT-H1 thermal compound, the NH-L9i-17xx 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 Intel LGA17xx family CPUs.
37mm low profile
Due to the slim 23mm heatsink and the NF-A9x14 low profile fan that measures only 14mm in thickness, the NH-L9 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-L9i has a 95x95mm footprint that complies exactly with the Intel LGA1700 (LGA17xx family) socket keep-out zone. This means that it won't cause issues with VRM heatsinks and doesn't overhang the RAM slots, so it's fully compatible with tall memory modules.
100% compatibility with PCIe cards on mini-ITX
Some mini-ITX motherboards have the PCIe slot sitting close to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95mm sized NH-L9i provides full compatibility with PCIe cards.
NF-A9x14 PWM premium fan
The highly optimised NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9i to stay remarkably quiet.
