Noctua NH-U9S 4U CPU Cooler

Award-winning NH-U Series

The NH-U9S belongs to Noctua’s renowned NH-U9 series, which has garnered acclaim and recognition since its introduction in 2005. This series has become the go-to choice for premium-quality, quiet CPU coolers, having earned over 800 awards and recommendations from leading international hardware websites and magazines.

Enhanced Compatibility with S Version

Building on the success of its predecessors, the NH-U9S features a revised and slimmer design. Unlike the NH-U9B SE2, which measured 120mm in depth with its two stock fans, the NH-U9S adopts an asymmetric layout and is now only 95mm deep with its single, more efficient NF-A9 fan. This provides improved performance and compatibility, making it an excellent choice for various setups.

RAM Compatibility and PCIe Compatibility on Mini-ITX

With its compact 95x95mm footprint, the NH-U9S offers full compatibility with RAM modules on most Intel and AMD mainboards. It does not overhang the RAM slots, ensuring convenient access and support for tall heatspreaders or optional memory fans. Additionally, the NH-U9S is designed to provide full compatibility with PCIe cards on mini-ITX mainboards, allowing for versatile system configurations.

NF-A9 Premium Fan and PWM Support

The NH-U9S is equipped with the highly optimized NF-A9 premium fan, featuring Noctua’s proprietary AAO frame and advanced aerodynamic design. This 92mm fan incorporates Flow Acceleration Channels to enhance airflow efficiency, resulting in superior cooling performance. It supports PWM for automatic speed control and includes a Low-Noise Adaptor to reduce the maximum fan speed for quieter operation.

Dual Fan Ready for Enhanced Cooling

For users seeking even greater cooling performance, the NH-U9S includes an extra set of fan mounting clips. This allows for the installation of an additional NF-A9 PWM fan, enabling a push/pull configuration. With the supplied y-cable, both fans can be conveniently connected to a single CPU fan header, further enhancing cooling capabilities.
