  • 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 optimized 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.

Noctua's low profile NH-L9i heatsink stands 36mm tall so it will fit into the smallest of small form factor chassis. The NH-L9i is designed to cool Intel socket LGA115x (1155/1156/1150) processors only, which is a departure from the one-size-fits-all...

Now it's time for my final thoughts on the Noctua NH-L9i Low Profile CPU Cooler designed for socket LGA 115X CPU's, how does it compare to its bigger brothers and how does it cope with the extreme heat of Haswell combined with a nice hot summers day?...

The Noctua NH-L9i is a great low-profile cooler for an HTPC and offers far better performance than Intel's stock...
