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 ensures 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 favourite 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. |
