Having received more than 300 awards and recommendations from international hardware websites and magazines, Noctua’s NH-U9 line has become a benchmark for compact 92mm single tower coolers. The TR4-SP3 version is a tailored custom model for AMD’s sTRX4/sWRX8/TR4/SP3 platform (Ryzen Threadripper / Epyc) and features a larger contact surface as well as the latest SecuFirm2™ mounting system for socket sTRX4/sWRX8/TR4/SP3. Topped off with two of the renowned quiet NF-A9 PWM PWM 92mm fans in a push/pull dual fan configuration, Noctua’s proven NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-U9TR4-SP3 forms a highly compact, premium-quality solution that combines outstanding performance, superb acoustics and excellent compatibility for space-restricted sTRX4/sWRX8/TR4/SP3 systems.
