Noctua CPU Cooler [NH-U12S redux]

The Noctua NH-U12S redux CPU cooler uses the same proven heatsink layout that guarantees 100% compatibility with tall RAM modules as well as excellent case and PCIe compatibility. Thanks to the popular NF-P12 redux-1700 PWM fan with automatic speed control, it provides high performance under load and runs whisper-quiet at idle. At the same time, Noctua’s renowned, professional SecuFirm2 mounting system and the pre-applied NT-H1 thermal compound make installation child’s play. Backed up with Noctua’s trusted quality, the NH-U12S redux is a smart, affordable choice for a quiet, high-quality 120mm cooler.

Classic 120mm tower size for excellent case and PCIe compatibility

Standing 158mm tall, the NH-U12S redux 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 most 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 redux will not overhang the RAM slots on any current platform. This gives the user full access to the memory modules and guarantees 100% compatibility with modules that feature tall heat-spreaders or RGB lighting.

Proven NF-P12 fan with PWM

Specifically designed for pressure-demanding applications such as on heatsinks, the classic NF-P12 is a long-standing favorite among quiet cooling enthusiasts. The higher-speed 1700rpm redux line version supports PWM for automatic speed control, which allows it to run near silent most of the time and provide massive performance when necessary.

Optional dual-fan kit

The optional NA-FK1 fan kit makes it possible to upgrade the NH-U12S redux with a second fan in order to achieve even better performance. Containing a second NF-P12 redux-1700 PWM fan, fan clips, anti-vibration pads, a y-cable and Low-Noise Adaptors, it gives plenty of options to fine-tune the cooler for further improved efficiency or quietness of operation.
