## Summary description

Noctua NH-D9 TR5-SP6 4U is a compact air cooler designed for sTR5 processors. It features two 92 mm fans (400–2500 RPM) with seven blades each, aluminium fins and a copper baseplate for efficient heat transfer. Maximum airflow is 96.3 m³/h with up to 30.6 dB noise. With a 9.5 cm radiator height and 769 g weight, it fits low-profile 4U systems and workstation builds.

## Long description

The Noctua NH-D9 TR5-SP6 4U is a premium 92mm quiet CPU cooler designed for workstations and servers using AMD Threadripper and Epyc processors with TR5/SP6 (sTRX5/sWRX9) sockets. It builds on the DX series dual-tower heatsink with a full-cover contact surface and includes two high-speed NF-A9 HS-PWM 92mm fans to deliver strong cooling performance with low noise. The cooler directs airflow parallel to the long axis of the socket, fits most 4U rack-mount enclosures with a total height of 134mm, and comes with pre-applied NT-H2 thermal compound and the SecuFirm2™ mounting system updated for TR5/SP6 pressure specifications.
Advantages
The enlarged copper contact surface (70 x 56 mm) is tailored for TR5/SP6 processors’ large integrated heat spreaders, improving heat transfer from the CPU to the heatpipes and fins. Its compact 95 x 95 mm footprint (with center fan only) and low height ensure excellent PCIe compatibility and fit in many 4U cases. The dual NF-A9 HS-PWM fans in push/pull configuration provide high cooling capacity for a compact cooler while the supplied Y-splitter and PWM control allow automatic, quiet speed regulation. The updated SecuFirm2™ mounting simplifies installation and the pre-applied NT-H2 paste guarantees optimal bond-line thickness and long-term thermal stability.
Key specifications
Socket compatibility: TR5 / SP6 (sTRX5 / sWRX9)
Heatsink contact surface: 70 x 56 mm
Fan size and type: 2 × 92 mm NF-A9 HS-PWM
Fan speed (max): 2500 RPM (HS-PWM variant)
Dimensions (with centre fan): 95 × 95 mm footprint, total height 134 mm
Configuration: Dual-tower heatsink, push/pull fan setup
Mounting: SecuFirm2™ TR5/SP6 mounting system
Thermal compound: Pre-applied NT-H2
How to use
Mount the heatsink on a compatible TR5 or SP6 socket following the SecuFirm2™ procedure: position the cooler, align the mounting holes, and tighten the four spring-loaded Allen key screws using the supplied tool. Connect the two NF-A9 fans to the motherboard fan header using the included Y-splitter so both fans run from a single PWM header. Ensure chassis airflow matches the cooler’s orientation (airflow parallel to the socket long axis) for optimal exhaust. If required, install the second fan on either side depending on available space.
Recommendations
Use the NH-D9 TR5-SP6 4U in 4U rack-mount systems or compact workstations where exhaust airflow is parallel to the socket axis. For systems needing perpendicular airflow, consider Noctua models designed for that orientation or use compatible adaptation kits. Regularly inspect fan connectors and ensure the NT-H2 bond remains clean during maintenance.
