The NH-U12A chromax.black is an all-black version of Noctua’s award-winning NH-U12A premium-quality quiet CPU cooler. Thanks to the same proven asymmetrical single-tower heatsink design and state-of-the-art NF-A12x25 PWM fans, it stays true to the NH-U12A’s successful formula of fusing best-in-class cooling performance with superb quietness of operation and outstanding RAM, case and PCIe compatibility. At the same time, the chromax.black version with its black fans and black coated heatsink combines these assets with a sleek stealth look. 100% RAM compatibility on LGA1700/1200 and AM4/AM5 Due to its asymmetric design, the NH-U12A does not overhang the RAM slots on Intel LGA1700 (LGA17xx family)/LGA1200/LGA115x and AMD AM4/AM5 based motherboards, which ensures easy access to the modules and 100% compatibility with tall heat-spreaders. On LGA2066, the rear fan will overhang the RAM slots on the left-hand side of the socket, so RAM modules should not exceed 42mm in height. * Classic 120mm tower size for excellent case and PCIe 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. Colour-customisable Standing 158mm tall, the NH-Using the optional NA-HC7 and NA-HC8 heatsink covers as well as the NA-SAVP1 anti-vibration pads (available in black, blue, green, red, yellow, white), the NH-U12A chromax.black can be fully customised to fit popular build colour schemes such as black and red or black and white.
