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 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.

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 ensuring 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.

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.

SecuFirm2 mounting system
Noctua's SecuFirm2 mounting systems have become synonymous with quality, safety and ease of use. Supporting Intel LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), LGA2011, LGA2066 and AMD (AM4, AM3+, AM2+, FM1, FM2, FM2+), the SecuFirm2 mounting included with the NH-U14S ensures perfect contact pressure and maximum convenience on all current sockets.

Pros: We chose the downward-firing version of this cooler for our vintage Core i7-965 Extreme Edition because the components surrounding the cpu socket benefit from having some air blow across them. The ol' 965 is a 130-watt heat monster, yet the Noctua maintains idle temps. of 32-36 deg. C. and peak temps. while gaming for a hour or more never exceed 64 deg. C. It manages this while running at only 900rpm (using the speed step-down option), and it's so quiet we use the system as a home theater PC. This result is achieved with 1 x 120mm front intake fan and 1 x 120mm rear exhaust fan, both running at a quiet 700rpm. The model on this page - NH-U14S - is about 2 deg. C. more effective due to the fact that it blows directly towards either the rear exhaust or top exhaust vent (instead of blowing downwards like our C14 version).
Cons: none except price!
