Noctua NH-U9S chromax.black - CPU cooler

The NH-U9S chromax.black is an all-black version of Noctua’s award-winning NH-U9S premium-quality quiet CPU cooler. Thanks to the same proven compact 92mm tower heatsink design and NF-A9 PWM fan, it stays true to the NH-U9S’s successful formula of fusing strong cooling performance with excellent quietness of operation and outstanding RAM, case 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™ multi-socket mounting system, Noctua’s enthusiast-grade NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-U9S chromax.black is a premium choice for customers who seek a compact, highly compatible 92mm heatsink that looks just as great as it cools.

Award-winning NH-U9S cooler
Tens of thousands of enthusiast users all over the world swear by the NH-U9S’s quality and performance. Recommended by more than 100 international hardware websites and magazines, it is renowned as being one of the best 92mm coolers on the market.

chromax.black design
The NH-U9S chromax.black is black from head to toe: Featuring a black coated heatsink, a black fan with black anti-vibration pads, black fan clips and black mounting parts, it is right at home in all-black builds and easy to integrate with other colour schemes.

Colour-customisable
Using the optional NA-SAVP5 anti-vibration pads (available in black, blue, green, red, yellow, white), the NH-U9S chromax.black can be fully customised to fit popular build colour schemes such as black and red or black and white.

100% RAM compatibility
With its 95x95mm footprint, the NH-U9S does not overhang the RAM slots on current Intel and most AMD mainboards. This gives the user full access to the memory modules and guarantees 100% compatibility with tall RGB modules, large heatspreaders or optional memory fans.

100% compatibility with PCIe cards on mini-ITX
Many mini-ITX motherboards have the PCIe slot sitting close to the socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95xmm sized NH-U9S provides full compatibility with PCIe cards, be it on ATX, microATX or ITX.

NF-A9 premium fan
The highly optimised features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, which allows it to further improve the renowned efficiency of Noctua's previous 92mm models and contributes to the NH-U9S' superior cooling performance.

Dual fan ready
The NH-U9S chromax.black includes an extra set of fan mounting clips for users who want to achieve even better cooling performance by adding a second, optional NF-A9 PWM chromax.black.swap fan in order to create a push/pull setup.

SecuFirm2™ multi-socket mounting system
Noctua's SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA1851, LGA1700 (since 2021), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) as well as AMD AM4 and AM5 (since 2019), the SecuFirm2™ mounting included with the NH-U9S is straightforward to install, provides perfect contact pressure and will stand the test of time even under heavy use.

Offset mounting option for AMD AM5
The NH-U9S chromax.black includes Noctua’s offset mounting bars for AM5 that make it possible to install the cooler shifted towards the south side of the socket by 7mm, thereby achieving better contact quality right above the CCD(s). This improved contact exactly at the processor’s hotspot can significantly reduce CPU temperatures with typical improvements in the range of 1-3°C.

Compatibility with past and future sockets
Thanks to Noctua’s SecuFirm™ ecosystem, the NH-U9S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets, which makes the NH-U9S a safe long-term investment.

NT-H1 thermal compound
Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua's NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability.

Soldered 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-U9S’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.
