Noctua CPU Cooler L9i Chromax Black

The NH-L9i chromax.black is an all-black version of Noctuas award-winning NH-L9i low-profile quiet CPU cooler for HTPCs and Small Form Factor (SFF) builds. Thanks to the same proven heatsink design and NF-A9x14 PWM fan, it stays true to the NH-L9is successful formula of fusing a height of only 37mm with strong performance and excellent quietness of operation, as well as 100% RAM and PCIe compatibility. At the same time, the chromax.black version with its black fan and black coated heatsink combines these assets with a sleek stealth look. Topped off with the renowned SecuFirm2 low-profile mounting system for Intel LGA115x, Noctuas enthusiast-grade NT-H1 thermal compound and a full 6-year manufacturers 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-L9is quality and performance. Recommended by more than 150 international hardware websites and magazines, it is renowned as being one of the best low-profile coolers on the market.

chromax.black designchromax.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 and black mounting parts, its right at home in all-black builds and easy to integrate with other colour schemes.

37mm low profile37mm 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 compatibility100% RAM compatibility
The NH-L9i has a 95x95mm footprint that complies exactly with the Intel LGA115x socket keep-out zone. This means that it wont cause issues with chipset coolers and doesnt overhang the RAM slots, so its fully compatible with tall memory modules.

100% compatibility with PCIe cards on mini-ITX 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 fanNF-A9x14 PWM premium fan
The highly optimised NF-A9x14 premium fan features Noctuas 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 AdaptorLow-Noise Adaptor
Allowing to reduce the maximum speed of the NF-A9x14 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 SecuFirm2 mounting for LGA115xCustom-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.

Optional SecuFirm2 mounting kit for AMD AM4Optional SecuFirm2 mounting kit for AMD AM4
While the NH-L9is construction is tailored to the keep-out zone of Intels LGA115x platform, it can be installed on many AMD AM4 boards using the optional NM-AM4-L9aL9i mounting kit, which can be ordered on Noctuas website free of charge.

NT-H1 thermal compoundNT-H1 thermal compound
Noctuas much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability. Chosen again and again by overclockers and enthusiast users worldwide, it has established itself as a benchmark for premium-quality thermal compounds.

Soldered interface between heatpipes and finsSoldered interface between heatpipes and fins
With many heatsinks, the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper and aluminium, this fit can loosen over years of thermal cycling, which may lead to reduced performance. By contrast, the NH-L9is fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesnt deteriorate even after many years of usage.
