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. 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 LGA2011
With its 52mm slim design tailor-made for 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.
