The NH-U12S is the latest 12cm model of Noctua’s classic U-series single tower CPU coolers, which have received more than 400 awards and recommendations from the international press. The S-version’s 45mm slim shape ensures 100% compatibility with tall RAM modules and at the same time, its fine-tuned design and the class-leading NF-F12 FocusedFlow fan with PWM support for fully automatic speed control allow it to further improve its predecessor’s renowned quiet cooling performance. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system and Noctua’s proven NT-H1 thermal compound, the NH-U12S is a complete premium quality solution that combines outstanding performance, quiet operation and excellent compatibility.

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 optimum compatibility with multi-GPU setups.

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.
