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 TR4/SP3 platform (Ryzen Threadripper / Epyc) and features a larger contact surface as well as the latest SecuFirm2™ mounting system for socket 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-U9 TR4-SP3 forms a highly compact, premium-quality solution that combines outstanding performance, superb acoustics and excellent compatibility for space-restricted TR4/SP3 systems.

SecuFirm2™ AMD TR4/SP3 installation
Award-winning NH-U series
The NH-U9 TR4-SP3 stems from Noctua's award-winning NH-U9 series. First introduced in 2005, the NH-U series has become a standard choice for premium quality quiet CPU coolers and won more than 1000 awards and recommendations from leading international hardware websites and magazines.
Tailored custom version for TR4/SP3 (Ryzen Threadripper / Epyc)
At 70x56mm, the copper contact surface of the TR4-SP3 version is more than double the size of the standard model. Tailored to fit the enormous integrated heat-spreaders (IHS) of AMD’s TR4/SP3-based processors, this customised design allows for an optimal heat flow from the CPU over the base to the heatpipes and on to the cooling fins.
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.
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.
PWM support and Low-Noise Adaptors
The NF-A9 premium fans supplied with the NH-U9 TR4-SP3 support PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 2000 to 1550rpm using the supplied Low-Noise Adaptors for even quieter operation.
SecuFirm2™ mounting system for 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!
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.
6-year manufacturer’s warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9’s feature an MTTF rating of more than 150,000 hours and the entire NH-U9 TR4-SP3 package comes with a full 6-year manufacturer’s warranty.
