Noctua NH-L9i 37mm Low Profile CPU Air Cooler
FEATURES

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’s fully compatible with tall memory modules.

100% compatibility with PCIe cards on mini-ITX
Most Intel LGA115x based mini-ITX motherboards 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 the maximum speed of the NF-A9x14 PWM fan to be reduced from 2500 to 1800rpm, the included Low-Noise Adaptor (LNA) makes it possible to achieve near-silent setups with suitable CPUs that only create smaller heat loads.

Custom-designed SecuFirm2™ mounting for LGA115x/1200
The NH-L9i bundles a custom-designed, backplate-less SecuFirm2™ mounting system for LGA115x/1200 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 pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.

6-year manufacturer’s warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9x14 features an MTTF rating of more than 150.000 hours and the entire NH-L9i package comes with a full 6-year manufacturer’s warranty.
