The NH-L9i chromax.black is an all-black version of Noctua’s award-winning NH-L9i low-profile quiet CPU cooler for HTPCs & Small Form Factor (SFF) builds. Thanks to the same proven heatsink design & NF-A9x 14 PWM fan, it stays true to the NH-L9i’s successful formula of fusing a height of only 37mm with strong performance & excellent quietness of operation, as well as 100% RAM & PCIe compatibility. At the same time, the chromax.black version with its black fan & black coated heatsink combines these assets with a sleek stealth look. Topped off with the renowned Secu Firm 2 low-profile mounting system for Intel LGA115x, Noctua’s enthusiast-grade NT-H1 thermal compound & a full 6-year manufacturer’s warranty, the NH-L9i chromax.black is a premium choice for customers who seek an ultra-compact heatsink that looks just as great as it cools. Award-winning NH-L9i cooler Tens of thousands of enthusiast users all over the world swear by the NH-L9i’s quality & performance. Recommended by more than 150 international hardware websites & magazines, it is renowned as being one of the best low-profile coolers on the market. chromax.black design The NH-L9i chromax.black is black from head to toe: Featuring a black coated heatsink, a black fan with black anti-vibration-pads, black fan screws & black mounting parts, it’s right at home in all-black builds & easy to integrate with other colour schemes. 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’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 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 to reduce the maximum speed of the NF-A9x 14 fan from 2500 to 1800rpm, the included (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. Optional Secu Firm 2 mounting kit for AMD AM4 While the NH-L9i’s construction is tailored to the keep-out zone of Intel’s LGA115x platform, it can be installed on many AMD AM4 boards using the optional NM-AM4-L9a L9i mounting kit, which can be ordered on Noctua’s website free of charge. 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 & outstanding reliability. Chosen again & again by overclockers & enthusiast users worldwide, it has established itself as a benchmark for premium-quality thermal compounds. Soldered interface between heatpipes & fins With many heatsinks, the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper & aluminium, this fit can loosen over years of thermal cycling, which may lead to reduced performance. By contrast, the NH-L9i’s fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage. 6-year manufacturer’s warranty Noctua products are renowned for their impeccable quality & outstanding longevity. Like all Noctua fans, the supplied NF-A9x 14 features an MTTF rating of more than 150.000 hours & the entire NH-L9i package comes with a full 6-year manufacturer’s warranty.
