140mm performance in 120mm size
Thanks to its completely revised, thoroughly optimised 7 heatpipe layout, 37% more fin surface area (as compared to the NH-U12S) and a dual fan push/pull configuration that uses the new, state-of-the-art NF-A12x25 fans, the NH-U12A pushes the performance envelope in the 120mm class and can actually match or even outperform many 140mm sized coolers.

100% RAM compatibility on LGA1851/LGA1700 and AM4/AM5
Due to its asymmetric design, the NH-U12A does not overhang the RAM slots on Intel LGA1851 / LGA1700 / LGA1200 / LGA115x and AMD AM4 / AM5 based motherboards, which ensures easy access to the modules and 100% compatibility with DIMMs that feature tall heat-spreaders.

Classic 120mm tower size for excellent overall compatibility
Standing 158mm tall, the NH-U12A 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.
