Noctua NH-L9I

  • Product Info

    The NH-L9i is a premium quality quiet CPU cooler for Intel LGA115x based HTPCs and Small Form Factor systems. At a super-low profile of only 37mm, the NH-L9i is ideal for extremely slim cases and due to its 95x95mm footprint, it provides full compatibility with tall RAM modules and VGA cards on mini-ITX mainboards. The custom designed SecuFirm2™ mounting system for LGA115x makes installation a child’s play and thanks to the highly optimised NF-A9x14 premium fan that supports fully automatic speed control via PWM, the NH-L9i runs remarkably quiet. Topped off with Noctua’s renowned NT-H1 thermal compound, the NH-L9i fuses everything users have come to expect from Noctua’s larger coolers into a super-compact package for slim HTPC systems.
