Continuing the legacy of Noctua’s classic NH-U-series, which has received more than a thousand awards and recommendations from international hardware websites and magazines, the NH-U14S has become a benchmark for high-end 140mm single tower coolers. The TR4-SP3 version is a tailored custom model for AMD’s sTRX4/TR4/SP3 platform (Ryzen Threadripper / Epyc) and features a larger contact surface as well as the latest SecuFirm2 mounting system for socket sTRX4/TR4/SP3. Topped off with the renowned quiet NF-A15 PWM 140mm fan, Noctua’s proven NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-U14S TR4-SP3 forms a complete premium-quality solution that combines maximum performance and superb acoustics for enthusiast-grade sTRX4/TR4/SP3 systems. Please note that the NH-U14S TR4-SP3 is a dedicated version for the AMD sTRX4/TR4/SP3 socket. Due to its customised larger base, it cannot be used on any other sockets and is incompatible with Noctua’s standard mounting kits.
