NH-U14S Slim Design for Full RAM Compatibility on LGA2011 CPU Cooler

The NH-U14S is the 14cm top model of Noctua’s classic U-series single tower CPU coolers, which have received more than 400 awards and recommendations from the international press. While the large, six heatpipe design and the NF-A15 140mm fan with PWM support for fully automatic speed control allow the cooler to best the renowned quiet cooling performance of all other U-series coolers, its 52mm slim shape still guarantees full compatibility with tall RAM modules on LGA2011/LGA2066. Topped off with the trusted, pro-grade SecuFirm2™ multi-socket mounting system, Noctua’s proven NT-H1 thermal compound and full 6 years manufacturer’s warranty, the NH-U14S is a complete premium quality solution that combines superb performance, high compatibility and quiet operation.

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 a standard choice for premium quality quiet CPU coolers and won more than 400 awards and recommendations from leading international hardware websites and magazines.

Full RAM compatibility on LGA20xx

With its 52mm slim design tailor-made for LGA20xx (LGA2066 & LGA2011), the NH-U14S will not overhang the RAM slots on this platform, thus guaranteeing full compatibility with tall memory modules. On some LGA115x and AMD motherboards, the front fan may overhang the first RAM slot, so standard height RAM (up to 32mm) should be chosen when using the first slot.*

Reasonable size for better overall compatibility

Standing 165mm tall, the NH-U14S is short enough to fit most modern high-end cases. Measuring 150mm wide (including fan and fan clips), the NH-U14S provides better compatibility with SLI and CrossFire setups as compared to tower coolers that are wider than 150mm or use fans wider than 150mm.

NF-A15 140mm PWM Fan

The NF-A15 is a premium quality quiet 140mm fan with a round frame that complies with Noctua's AAO standard. Featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A15 further improves the renowned quiet cooling performance of the award-winning NF-P14.

PWM support and Low-Noise Adaptor

The NF-A15 140mm fan supplied with the NH-U14S supports PWM for convenient automatic speed control through the mainboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptor for even quieter operation.

Anti-vibration pads and fan-clips for second NF-A15 (optional)

For users who want to achieve even better performance by adding a second, optional NF-A15 fan to create a push/pull setup, the NH-U14S includes fan clips and an extra set of custom-designed anti-vibration pads that allow to off-set the rear fan by 5mm to improve acoustics in dual-fan mode.*

SecuFirm2™ mounting system

Noctua's SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA1700 (since 2021), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), LGA2011, LGA2066 and AMD (AM4, AM5 (since 2019), the SecuFirm2™ mounting included with the NH-U14S guarantees perfect contact pressure and maximum convenience on all current sockets.

Compatibility with past and future sockets

Complying with the open SecuFirm™ standard, the NH-U14S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided by Noctua free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets.

NT-H1 thermal compound

Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua's NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability.

6-year manufacturer’s warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A15 features an MTTF rating of more than 150.000 hours and the entire NH-U14S package comes with a full 6-year manufacturer's warranty.
