Noctua NH-D9 TR5-SP6 4U CPU Cooler
The Noctua NH-D9 TR5-SP6 4U is a premium dual-tower CPU cooler specifically engineered for AMD Ryzen Threadripper and EPYC processors using the sTR5, SP6 and SP5 platforms in space-constrained workstation and server environments. Designed for 4U rackmount compatibility, the cooler combines a compact 134mm height with Noctua’s proven dual-tower heatsink architecture and dual NF-A9 HS-PWM 92mm fans to deliver high-performance cooling for demanding multi-core processors. The enlarged contact surface has been specifically optimised for AMD's large TR5 and SP6 processor heat spreaders, ensuring efficient heat transfer across the entire CPU package. Featuring a fully nickel-plated heatsink, soldered fin construction, four heatpipes and industrial-grade SecuFirm2 mounting, the NH-D9 TR5-SP6 4U delivers the reliability, cooling performance and acoustic refinement expected from Noctua while maintaining compatibility with 4U rackmount chassis and professional workstation systems.
Purpose-Built for AMD Threadripper and EPYC
The CPU cooler has been developed specifically for AMD Ryzen Threadripper Pro 9000 WX-Series, Ryzen Threadripper Pro 7000 WX-Series, Ryzen Threadripper 9000 Series, Ryzen Threadripper 7000 Series, EPYC 9005 Series, EPYC 9004 Series, EPYC 8004 Series and EPYC 4004 Series processors using the sTR5, SP6 and SP5 sockets. Unlike conventional desktop coolers, the NH-D9 TR5-SP6 4U features a significantly enlarged copper contact plate designed to fully cover AMD's large workstation and server processor heat spreaders, helping maximise heat transfer efficiency across high-core-count CPUs.
Compact Dual-Tower 4U Design
The NH-D9 TR5-SP6 4U utilises a compact dual-tower heatsink configuration with an overall height of 134mm, making it suitable for 4U rackmount systems and space-conscious professional workstations. Four 6mm copper heatpipes distribute thermal energy efficiently between both fin stacks, while the dual-tower arrangement increases cooling surface area without significantly increasing system footprint. The design also provides excellent compatibility with surrounding motherboard components in professional workstation platforms.
Dual NF-A9 HS-PWM Fans
The CPU cooler is equipped with two NF-A9 HS-PWM 92mm fans configured in a push-pull arrangement. Operating between 600 and 2500RPM via PWM control, the fans utilise Noctua's advanced aerodynamic blade design and premium SSO2 bearing technology to provide a balance of airflow, static pressure and acoustic performance. PWM regulation enables the cooling system to dynamically adjust fan speed according to thermal demand, reducing unnecessary noise during lighter workloads while maintaining cooling capacity when processor utilisation increases.
Enterprise-Class Reliability and Installation
The NH-D9 TR5-SP6 4U incorporates Noctua's SecuFirm2 mounting system, providing a secure installation process tailored specifically for AMD workstation and server sockets. The cooler includes pre-applied NT-H2 thermal compound to simplify installation while ensuring consistent thermal performance from first use. Fully soldered fins and heatpipes, nickel-plated copper contact surfaces and Noctua's renowned manufacturing quality contribute to long-term durability in professional environments where reliability is critical.
Optimised for Workstations and Rackmount Systems
Designed with workstation and server deployments in mind, the NH-D9 TR5-SP6 4U provides an effective cooling solution for systems where chassis height restrictions would prevent the use of larger tower coolers. The combination of compact dimensions, specialised AMD platform optimisation and dual-fan airflow delivery enables the cooler to support demanding professional workloads while maintaining compatibility with a wide range of 4U rackmount and workstation chassis configurations.
