Noctua NH-L9i Intel-only Low Profile Quiet CPU Cooler
Introducing Noctua’s smallest cooler to date. The NH-L9i stands just 37mm tall and is designed only for Intel CPUs that output a maximum of 95 watts TDP.
Features
- 37mm low profile
- For use with processors up to 96W
- 100% RAM compatibility
- 100% compatibility with PCIe cards on mini-ITX
- NF-A9x14 PWM premium fan
- Compatible with Intel LGA1200/1150/1155/1156/1151
- Six years manufacturer’s warranty
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 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.
37mm low profile
Due to the slim 23mm heatsink and the NF-A9x14 low profile fan that measures only 14mm in thickness, the NH-L9 stands a mere 37mm tall, which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers.
100% RAM compatibility
The NH-L9i has a 95x95mm footprint that complies exactly with the Intel LGA115x socket keep-out zone. This means that it won’t cause issues with chipset coolers and doesn’t overhang the RAM slots, so it is fully compatible with tall memory modules.
100% compatibility with PCIe cards on mini-ITX
Most Intel LGA115x based mini-ITX mainboards have the PCIe slot sitting right next to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95xmm sized NH-L9i provides full compatibility with PCIe cards.
NF-A9x14 PWM premium fan
The highly optimised NF-A9x14 premium fan features Noctua’s proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9i to stay remarkably quiet.
Low-Noise Adaptor
Allowing a reduction of the maximum speed of the NF-A9x14 fan from 2500 to 1800rpm, the included Low-Noise Adaptor (L.N.A.) makes it possible to achieve near-silent setups using CPUs with less than 65W TDP.
Custom-designed SecuFirm2 mounting for LGA115x
The NH-L9i bundles a custom-designed, backplate-less SecuFirm2 mounting system for LGA115x that offers extended compatibility with mini-ITX boards and makes installation easier than ever, all while maintaining the trusted SecuFirm2 quality.
NT-H1 thermal compound
Noctua’s much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.
6 years manufacturer’s warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9x14 features an MTBF rating of more than 150.000 hours and the entire NH-L9i package comes with a full 6 year manufacturer’s warranty.
Caution: The NH-L9i is a highly compact, quiet low-profile cooler designed for use in small form factor cases and HTPC environments. While it provides first-rate performance in its class, it is not suitable for overclocking and or CPUs that create high heat loads. Please consult Noctua’s CPU compatibility list to find out whether the NH-L9i is recommended for your CPU.
Review
SilentPCReview.com
The NH-L9i primary advantage lies in its acoustics — its fan sounds incredibly smooth compared to the more buzzy Scythe model — and its virtually guaranteed fit on any LGA1155 board, including mini-ITX, without interfering with any components or add-ons.

Customer Reviews
High quality component - very low noise
Used this to replace a standard, noisy Intel branded fan. Very high quality manufacturing and finish. At least as effective as the fan that was removed (cooling an Intel Core i3-2100S @ 3.10 GHz - the low power model). Clear documentation. The only downside is the small case fan is now audible (but not above the ambient noise in my room).
