Dedicated version for sTRX4/TR4/SP3. Incompatible with other sockets.

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/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 two of the renowned quiet NF-A9 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/TR4/SP3 systems.



Key features

Compact 92mm size for best compatibility

Thanks to a total width of only 95mm, the NH-U9 TR4-SP3 provides 100% PCIe clearance and never overhangs the top PCIe x16 slot. At the same time, its height of only 125mm allows it to fit smaller cases and most 4U size rack-mount enclosures.

SecuFirm2™ mounting system for sTRX4/TR4/SP3

Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and ease of use. The TR4-SP3 variant has been completely custom-designed for the new socket and is particularly easy to install: Put on the heatsink, fix the four spring-loaded screws and you’re done!

Dual NF-A9 PWM fans

The NH-U9 TR4-SP3 is equipped with two of Noctua’s award-winning NF-A9 PWM 92mm fans. This push/pull dual fan configuration allows it to achieve a level of quiet cooling performance that is remarkable for such a compact cooler and comes close to the bigger NH-U12S TR4-SP3.

NT-H1 thermal compound

Noctua'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.
