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 assures full compatibility with tall RAM modules on LGA2011/LGA2066. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system and Noctua’s proven NT-H1 thermal compound, the NH-U14S is a complete premium quality solution that combines superb performance, high compatibility and quiet operation.

Reasonable size for better overall compatibilityStanding 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 multi-GPU setups as compared to tower coolers that are wider than 150mm or use fans wider than 150mm. |
Full RAM compatibility on LGA20xxWith its 52mm slim design tailor-made for LGA20xx (LGA2066 & LGA2011), the NH-U14S will not overhang the RAM slots on this platform, thus ensuring full compatibility with tall memory modules. On some LGA1200/115x 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. |
NF-A15 140mm PWM FanThe 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. |
NT-H1 thermal compoundNoctua’s much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability, which makes it suitable for use in professional server and workstation environments. |
