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.
