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. 37mm low profile Due to the slim 23mm heatsink & the NF-A9x 14 low profile fan that measures only 14mm in thickness, the NH-L9 stands a mere 37mm tall, which makes it absolutely ideal to be used in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers. 100% RAM compatibility The NH-L9i has a 95x 95mm footprint that complies exactly with the Intel LGA115x socket keep-out zone. This means that it won't cause issues with chipset coolers & 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 95x 95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x 95xmm sized NH-L9i provides full compatibility with PCIe cards. NF-A9x 14 PWM premium fan The highly optimised NF-A9x 14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x 14 allows the NH-L9i to stay remarkably quiet. Low-Noise Adaptor Allowing a reduction of the maximum speed of the NF-A9x 14 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 Secu Firm 2 mounting for LGA115x The NH-L9i bundles a custom-designed, backplate-less Secu Firm 2 mounting system for LGA115x that offers extended compatibility with mini-ITX boards & makes installation easier than ever, all while maintaining the trusted Secu Firm 2 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 & outstanding reliability.
