Low-profile CPU cooler for HTPC

Overview
Ideal fan for compact PCs

The NH-L9i is a high-end silent CPU fan for HTPC and Small Form Factor systems featuring the Intel LGA115x. With its extremely low height of37mm, the NH-L9i is the ideal companion for extremely slim cases. Its 95x95mm footprint also ensures compatibility with the high RAM modules and VGA cards found on mini-ITX motherboards.

The exclusive SecuFirm2 mounting system for LGA115x makes installation a breeze. The high-end NF-A9x14 fan, whose speed can be fully automated via PWM, allows the NH-L9i to operate with amazing silence. Complemented by the renowned NT-H1 thermal paste, the NH-L9i combines everything users have come to expect from larger Noctua fans in an ultra-small HTPC format.

Low height of 37mm
With a slim 23mm heatsink combined with the NF-A9x14 low-profile fan that is only 14mm thick, the NF-A9x14 offers an overall height of only 37mm... making it ideal for HTPCs and SFF cases.
Full RAM Compatibility
The NH-L9i occupies a space of 95x95mm, which means you won't have any space problems. Compatibility is maintained even with high memory arrays
Full compatibility with VGA cards on mini-ITX
While larger fans extend beyond the normal area and prevent the use of PCIe, the NH-L9i's footprint(95x95mm) ensures full compatibility with PCIe cards.
NF-A9x14 PWM: a high performance fan
The NF-A9x14 fan features a highly optimised AAO frame for outstanding aerodynamic performance. With PWM support, the NF-A9x14 keeps the NH-L9i surprisingly quiet.
Low Noise Adapter
By offering the ability to cap the maximum speed of the NF-A9x14(1800rpm instead of 2500rpm), the Low Noise Adapter allows for nearly inaudible configurations with CPUs having a TDP of less than 65W.
Exclusive SecuFirm2 mounting system for LGA115x
The NH-L9i comes with a custom SecuFirm2 system for LGA115x without a backplate. This feature further improves compatibility with mini-ITX motherboards and makes installation easier than ever.
NT-H1 Thermal Paste
Noctua's renowned NT-H1 is a proven professional TIM solution that offers minimal thermal resistance, ease of application and outstanding reliability.
6-year manufacturer's warranty
Noctua fans are known for their impeccable quality and amazing longevity. Like all Noctua fans, the NH-L9i has an MTBF of more than 150,000 test hours and comes with a 6-year manufacturer's warranty.
Information provided by our tech department Warning: The NH-L9i is an ultra-compact silent fan with a reduced size, designed for small cases and HTPCs. It is not suitable for overclocking and requires certain precautions if used with processors with a TDP (Thermal Design Power) greater than 65W.

    Beautiful

    Very nice, very complete kit with paste and cpu4 extension. Easy to assemble as long as the motherboard can be removed. Very compact, fits very well on a micro-atx card and in a crowded desktop. Does not interfere with memory sticks. Almost silent after the Intel kit. Thanks Noctua. I hope I won't be disappointed by the longevity.
