In keeping with the spirit of the Noctua Redux line, the NOCTUA NH U12S Redux COOLING AIR is a streamlined, accessible version of the iconic NH-U12S that has established itself as the benchmark for slim, highly compatible 120mm CPU coolers.

The redux version uses the same heatsink design which ensures 100% compatibility with long 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 delivers high performance under load and operates whisper quietly at idle.

At the same time, Noctua’s popular, professional-grade SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound make installation child’s play. Backed by Noctua’s trusted 6-year manufacturer’s warranty, the NH-U12S redux is a smart, affordable option for a high-quality, quiet 120mm cooler.


Features of the NOCTUA NH U12S Redux Cooling AIR

  • Based on the award winning NH-U12S
    The NH-U12S Reuse builds on Noctua’s proven, high-quality NH-U12S, which is widely recognized as one of the best 120mm single-tower slim coolers on the market. Having received more than 200 awards and recommendations from international hardware websites and magazines, the NH-U12S has convinced tens of thousands of customers around the world.
  • Re-simplified edition
    Following the idea of the Noctua re-line, the NH-U12S redux takes the proven concept of the original NH-U12S and reduces it to its core: a quiet, high-quality 120mm cooler with streamlined accessories that are highly compatible and easy to install.
  • Classic 120mm tower size for excellent case and PCIe compatibility
    At 158mm tall, the NH-U12S’s revive is short enough to fit most modern mid- or high-end tower cases. Measuring 125mm (including the fan and fan clamps), the cooler stays clear of the top PCIe slot on most standard ATX or Micro-ATX motherboards, ensuring optimal compatibility with multi-GPU setups.
  • 100% RAM Compatibility
    With its slim design with a fin depth of just 45mm, the NH-U12S’ return won’t burden you with RAM slots on any current platform. This gives the user full access to the memory modules and ensures 100% compatibility with modules that feature long heatsinks or RGB lighting.
  • NF-P12 fan installed with PWM
    Designed specifically for pressure-demanding applications such as heatsinks, the NF-P12 is a longtime favorite among quiet cooling enthusiasts. The high-speed repeater line version supports 1700rpm PWM for automatic speed control, allowing it to operate near silent most of the time and provide massive performance when necessary.
  • Optional dual fan kit
    The optional NA-FK1 Fan Kit allows the NH-U12S to be upgraded with a second fan for even better performance. Featuring a second NF-P12 redux-1700 PWM fan, fan clips, anti-vibration pads, cable-y and low-noise adapters, it offers plenty of options for tuning the cooler to improve efficiency or run quieter.
  • Precision machined copper base for optimal contact and heat distribution
    The minimally convex copper base is essential to ensuring optimal contact quality on today’s CPUs as well as heat distribution across all heatpipes. While many coolers ignore this key part in order to cut costs, the NH-U12S re-engineer uses the same type of copper base as the original NH-U12S, which is precision-machined for optimal contact quality.
  • SecuFirm2™ multi-socket mounting system
    Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and ease of installation. Support for Intel LGA1700 (since 2021), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) and LGA20xx (LGA2066, LGA2011-0, LGA2011-3), plus AMD AM4 and AM5, SecuFirm2™ carrier included with NH-U12S redux Easy to install, provides optimal connection pressure and will stand the test of time even under heavy use.
  • Free upward upgrade policy
    Just as with more expensive Noctua coolers, incremental upgrade kits for the NH-U12S redux will be provided free of charge if technically feasible, making it a safe long-term investment. Customers can also order kits for legacy sockets, such as the LGA775 or LGA1366, for free on the Noctua website.
  • Pre-applied NT-H1 thermal compound
    Selected time and time again by overclocking professionals and enthusiast users the world over, Noctua’s NT-H1 has established itself as the benchmark for high-quality thermal compounds. The NH-U12S comes back with a thin layer of NT-H1 pre-applied to the base of the heatsink, making installation easier and eliminating any guesswork about how much adhesive to use.
  • 6 year manufacturer’s warranty
    Noctua products are known for their excellent quality and longevity. True to that legacy, the NH-U12S reset does not cut any corners, and as with all Noctua fans, the MTTF-rated NF-P12 returns over 150,000 hours. The entire package comes with a full 6-year manufacturer’s warranty.
