While the large design with six heat pipes and the NF-A15 140mm fan with PWM support for automatic speed control allows the cooler to best the quiet cooling performance popular with all other U-series coolers, its slim 52mm profile still ensures a perfect fit with length.

RAM modules on LGA2011 / LGA2066. Equipped with Noctua’s proven SecuFirm2™ multi-socket mounting system, Noctua’s proven NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-U14S is a complete high-quality solution that combines great performance with high compatibility and quietness.


Features of the NOCTUA NH U14S COOLING AIR

  • Award-winning NH-U series
    The NH-U14S is the first 140mm model in Noctua’s award-winning NH-U series. First introduced in 2005, the NH-U series has become the standard choice for high-quality, quiet CPU coolers and has received over 400 awards and recommendations from leading international hardware magazines and websites.
  • Full compatibility with LGA20xx RAM
    With its slim 52mm design designed specifically for the LGA20xx (LGA2066 & LGA2011), the NH-U14S will not flex the RAM slots on this platform, ensuring full compatibility with extended memory modules. On some LGA115x and AMD motherboards, the front fan may bypass the first RAM slot, so standard height RAM (up to 32mm) should be selected when using the first slot. *
  • Reasonable size for better overall compatibility
    Standing at 165mm tall, the NH-U14S is short enough to fit most modern high-end cases. At 150mm wide (including fan and fan clips), the NH-U14S offers better compatibility with SLI and CrossFire setups than tower coolers wider than 150mm or using fans wider than 150mm.
  • NF-A15 140mm PWM fan
    The NF-A15 is a high quality, quiet 140mm circular frame fan that complies with Noctua’s AAO standard. Featuring cutting-edge aerodynamic design measures such as flow acceleration ducts, the NF-A15 improves on the award-winning NF-P14’s famous quiet cooling performance.
  • PWM support and low noise converter
    The supplied NF-A15 140mm fan with NH-U14S PWM supports automatic speed control via the mainboard. In addition, the maximum fan speed can be reduced from 1,500 to 1,200 rpm with the supplied low-noise adapter for quieter operation.
  • Anti-vibration pads and fan clips for the second NF-A15 (optional)
    For users who want to achieve even better performance by adding an optional second NF-A15 fan to create a push/pull setup, the NH-U14S includes fan clamps and an additional set of specially designed anti-vibration pads that allow off-setting – adjust the rear fan by 5mm for improved performance. Acoustics in dual fan mode. *
  • SecuFirm2™ mounting system
    Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and ease of installation. Supported by Intel LGA1700 (since 2021), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), LGA2011, LGA2066, AMD (AM4 and AM5 (since 2019), the SecuFirm2™ bracket included with the NH-U14S ensures optimal contact pressure and Maximum convenience over all existing sockets.
  • Compatibility with past and future intakes
    In compliance with the open SecuFirm™ standard, the NH-U14S can be made compatible with legacy LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, provided free of charge by Noctua. If technically feasible, Noctua will also provide upgrade kits for future sockets.
  • Thermal compound NT-H1
    Having received over 100 awards and recommendations from hardware journalists around the world, Noctua’s NT-H1 is a proven, professional-quality TIM solution that offers minimal thermal resistance, excellent ease of use, and superior reliability.
  • 6 year manufacturer’s warranty
    Noctua products are known for their excellent quality and longevity. Like all Noctua fans, the MTTF-rated NF-A15 boasts a lifespan of over 150,000 hours and the entire NH-U14S package comes with a full 6-year manufacturer’s warranty.
