NOCTUA NH-U9S chromax.black is the all-black version of the award-winning NH-U9S premium quality, silent CPU cooler. Thanks to the proven compact 92mm tower cooler design and the NF-A9 PWM fan, it stays true to the NH-U9S's successful formula, which combines strong cooling performance with excellent quiet operation and excellent RAM, case and PCIe compatibility. At the same time, the chromax.black version, with its black fan and black-coated heatsink, combines these advantages with an elegant, hidden appearance. Featuring the renowned SecuFirm2™ multi-slot mounting system, Noctua's enthusiast-grade NT-H1 thermal paste, and a full 6-year manufacturer's warranty, the NH-U9S chromax.black is the premium choice for customers looking for a compact, highly compatible 92mm heatsink that looks as good as it cools.

Award-winning NH-U9S cooler
Tens of thousands of enthusiastic users worldwide swear by the quality and performance of the NH-U9S. Recommended by more than 100 international hardware websites and magazines, it is considered one of the best 92mm coolers on the market.

chromax.black design
The NH-U9S chromax.black is black from top to bottom: with a black-coated heatsink, black fan with black anti-vibration inserts, black fan mounts and black fasteners, it perfectly matches the all-black design and easily integrates with other color schemes.

Can be customized by color
With the optional NA-SAVP5 anti-vibration pads (available in black, blue, green, red, yellow, white), the NH-U9S chromax.black can be fully customized to match popular color schemes such as black and red or black and white.

100% RAM compatibility
With a size of 95x95 mm, the NH-U9S does not stick out of the RAM sockets of current Intel and most AMD motherboards. This gives the user full access to the memory modules and guarantees 100% compatibility with high RGB modules, large heatsinks or optional memory fans.

100% compatibility with mini-ITX PCIe cards
On many mini-ITX motherboards, the PCIe slot is located close to the socket zone. While larger coolers that extend beyond this zone are likely to cover the PCIe slot, the 95x95mm NH-U9S provides full compatibility with PCIe cards, be they ATX, microATX or ITX motherboards.

NF-A9 premium fan
The highly optimized NF-A9 features Noctua's proprietary AAO frame, as well as sophisticated aerodynamic design solutions such as flow-acceleration channels, which enable further improvements to the acclaimed efficiency of Noctua's previous 92mm models and contribute to the excellent cooling performance of the NH-U9S.

PWM support and low noise adapter
The NF-A9 92mm fan included with the NH-U9S supports PWM for convenient automatic speed control via the motherboard. In addition, the maximum fan speed can be reduced from 2000 to 1550 rpm with the included low-noise adapter for even quieter operation.

Equipped with a double fan
The NH-U9S chromax.black includes a set of extra fan mounting clips for users who want even better cooling performance by adding a second, optional NF-A9 PWM chromax.black.swap fan to create a push/pull arrangement.

SecuFirm2™ multi-socket fastening system
Noctua's SecuFirm2™ mounting systems have become synonymous with quality, security and ease of installation. The SecuFirm2™ mounting system supporting Intel LGA1851, LGA1700 (since 2021), LGA1200 and LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) and AMD AM4 and AM5 standards is included with the NH-U9S, easy to install, provides perfect contact pressure and stands the test of time even under heavy use.

Offset mounting option for AMD AM5
The NH-U9S chromax.black features Noctua's offset AM5 mounting arms, which allow the cooler to be moved 7mm south of the socket for better contact quality directly above the CCD(s). This improved contact right at the processor's hotspot can significantly reduce CPU temperatures, typically improving by 1-3°C.

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

NT-H1 thermal paste
Noctua's highly regarded NT-H1 is a professional TIM solution that provides minimal thermal resistance, excellent ease of use and outstanding reliability. Chosen time and time again by tuners and enthusiasts around the world, premium quality thermal pastes
