Noctua NH-U9 TR4-SP3 Ryzen Threadripper Epyc CPU Cooler

Noctua's NH-U9 TR4-SP3 is an excellent choice for AMD's Threadripper CPUs where space is limited. It supports CPUs with a maximum of 180W but does not support overclocking.


  1. Award-winning NH-U series
  2. Tailored custom version for TR4/SP3
  3. 2x 92mm fans for excellent performance
  4. Anti-vibration pads and fan-clips for second fan
  5. Max TDP 180W, no overclocking (not 250W TDP compatible)

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 manufacturers warranty, the NH-U9TR4-SP3 forms a highly compact, premium-quality solution that combines outstanding performance, superb acoustics and excellent compatibility for space-restricted TR4/SP3 systems.

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 performance of 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.

Anti-vibration pads and fan-clips for second NF-F12 (optional)

For users who want to achieve even better performance by adding a second, optional NF-F12 fan to create a push/pull setup, the NH-U12S includes fan clips and an extra set of custom-designed anti-vibration pads that allow to off-set the rear fan by 5mm to improve acoustics in dual-fan mode.

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

Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua's NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability.

6-year manufacturers warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-F12 features an MTTF rating of more than 150.000 hours and the entire NH-U12S package comes with a full 6-year manufacturer's warranty.

250W TDP Cooling?

The AMD Ryzen Threadripper series consists of powerful processors with higher cooling requirements. While standard mainstream processors usually have a TDP rating of 65-105W AMD Ryzen Threadripper (and Eypc) models are available with TDP ratings of 180W and 250W, which provides challenges not only for the CPU cooler as such but also for chassis ventilation. According to Noctua it is possible but not recommended to use this CPU cooler on a 250W CPU. The CPU usually stays above the rated base clock but very limited Precision Boost headroom, please consider the U14 or U12 TR4 coolers.

PLEASE NOTE: The NH-U9 TR4-SP3 is a dedicated version for the AMD 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.
