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 SecuFirm2TM 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.
