. The NH-L9i is a premium quality quiet CPU cooler for Intel LGA115x based HTPCs & Small Form Factor systems. At a super-low profile of only 37mm the NH-L9i is ideal for extremely slim cases & due to its 95x 95mm footprint it provides full compatibility with tall RAM modules & VGA cards on mini-ITX mainboards. The custom designed Secu Firm 2 mounting system for LGA115x makes installation child's play & thanks to the highly optimised NF-A9x 14 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..
