Noctua NH-D9 TR5-SP6 4U cooler

Noctua NH-D9 TR5-SP6 4U — compact server cooler

Optimized for servers and workstations with AMD processors on socket SP6 and TR5, the Noctua NH-D9 TR5-SP6 4U is the ideal solution for devices in 4U rack cabinets. With a height of just 134 mm, it easily fits into limited spaces without compromising on cooling efficiency. Two NF-A9 HS-PWM fans measuring 92 × 92 × 25 mm ensure high airflow of up to 78.9 m³/h while keeping noise levels to a maximum of just 22.8 dB(A). This cooler not only excels in efficient heat dissipation, but also in a long service life thanks to fans with an MTTF of over 150,000 hours.

Cooling efficiency with quiet operation

Two NF-A9 HS-PWM fans in a dual-tower configuration provide excellent cooling performance needed for demanding server applications. With support for PWM speed control (up to 2000 RPM), the speed adapts to the current load and ensures the optimal balance between quiet operation and heat dissipation. This makes the cooler suitable for environments where low noise is key.

Compatibility and easy installation

The cooler is specially designed for AMD processors on sockets SP6 and TR5, ensuring perfect contact with the processor and effective heat dissipation. The SecuFirm2™ mounting system guarantees quick, easy and secure installation. Thanks to its compact dimensions, the cooler is perfect for 4U rack cabinets where space is limited.

Reliability and long life

Fans with an MTTF of over 150,000 hours provide long-term reliability, which is essential for servers and workstations with non-stop operation. The included NT-H1 quality thermal paste improves heat transfer and contributes to overall cooling efficiency. Combined with the 6-year warranty, this cooler is an investment in reliable, long-lasting performance.
