Noctua NH-U12S DX-3647 Noctua NH-U12S DX-3647

Continuing the legacy of Noctua’s classic NH-U-series, the NH-U12S has become a benchmark for slim, highly compatible 120mm single tower coolers. The SE-AM4 version is a dedicated special edition for AMD’s AM4 (Ryzen) platform, featuring the latest SecuFirm2 mounting system for AM4. Topped off with the renowned quiet NF-F12 PWM 120mm fan, and Noctua’s proven NT-H1 thermal compound, the NH-U12S SE-AM4 forms a complete premium-quality solution that combines outstanding performance, superb acoustics and excellent compatibility for AM4 systems.

Classic 120mm tower size for excellent overall compatibility

Standing 158mm tall, the NH-U12S is short enough to fit most modern mid- or high-end tower cases. Measuring 125mm wide (including fan and fan clips), the cooler stays clear of the top PCIe slot on standard ATX or Micro-ATX motherboards, ensuring best compatibility with SLI and CrossFire setups.

Noctua NH-U12S DX-3647

100% RAM compatibility

Thanks to its slim design with only 45mm fin depth, the NH-U12S will not overhang the RAM slots even with two fans installed. This gives the user full access to the memory modules on all current CPU sockets and ensures 100% compatibility with tall heatspreaders or optional memory fans.

SecuFirm2 mounting system for AM4

Noctua’s SecuFirm2 mounting systems have become synonymous with quality, safety and ease of use. In order to achieve the best compatibility and to match the airflow path inside the case, the SecuFirm2 mounting for AM4 makes it possible to install the cooler either in standard orientation or turned by 90°.
