Noctua NH-U9 TR4-SP3 CPU Cooler
The NH-D9 TR5-SP6 4U is a 92mm size premium quality quiet CPU cooler for workstations and servers based on AMD Threadripper and Epyc processors that utilise sTR5/SP6 sockets. Built on the proven basis of the DX model with its dual tower heatsink and full-cover contact surface, the TR5-SP6 revision employs two of Noctua’s award-winning, PWM controlled NF-A9 92mm fans in their higher speed variant in order to achieve strong performance and superb acoustics. The NH-D9’s direction of airflow is parallel to the long axis of the socket, so it is ideal for builds where the hot air is exhausted this way. Topped off with the pre-applied NT-H2 thermal compound as well as the professional SecuFirm2™ mounting system for sTR5/SP6 that has been updated to meet the platform’s increased pressure specifications, the NH-D9 TR5-SP6 4U forms a complete premium quality package for quietly cooling sTR5-based Threadripper workstations and SP6-based Epyc servers in 4U cases

Proven heatsinks for AMD Threadripper & Epyc
First introduced in 2017, Noctua’s Threadripper and Epyc coolers have become a standard choice when it comes to quiet, premium grade air cooling solutions for AMD-based workstations and servers. Thanks to their superior acoustic efficiency, they are ideal for Threadripper and Epyc systems that run in noise sensitive environments (e.g. audio/video production, content creation, engineering, etc.)

Enlarged contact surface
At 70x56mm, the heatsink’s copper contact surface is more than double the size of the standard desktop model. Tailored to fit the enormous integrated heat-spreaders (IHS) of AMD’s sTR5/SP6 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 its compact footprint (95x95mm with centre fan only, second fan can be installed on either side depending on available space) and a total height of only 134mm, the NH-D9 TR5-SP6 4U provides excellent PCIe compatibility and is small enough to fit most 4U size rack-mount enclosures

Airflow parallel to long axis of the socket
The NH-D9’s direction of airflow is parallel to the long axis of the sTR5/SP6 socket, so it is ideal for systems where the exhaust fans of the chassis are in this direction. For systems that require the airflow to go perpendicular to the long axis of the socket, please choose the NH-U14S TR5-SP6 or adapt NH-U12S DX-4677 and NH-U9 DX-4677 coolers using the NM-TR5-SP6 kit

Dual NF-A9 HS-PWM fans
The NH-D9 TR5-SP6 4U is equipped with two of Noctua’s award-winning NF-A9 PWM 92mm fans in their high-speed 2500rpm HS-PWM variant. This push/pull dual fan configuration makes it possible to achieve a level of cooling performance that is remarkable for such a compact cooler

PWM support and splitter cable
The NF-A9 premium fans supplied with the NH-D9 TR5-SP6 4U support PWM for convenient automatic speed control through the motherboard, which allows them to run near silent at lighter loads and to speed up only when necessary. The supplied splitter cable makes it possible to power and control both fans simultaneously from a single motherboard fan header

SecuFirm2 mounting for TR5-SP6
The NH-D9 TR5-SP6 4U combines the proven basis of the DX model with new mounting brackets for AMD’s sTR5/SP6 socket. Installation is just as easy as with the previous TR4-SP3 models: Put on the heatsink, fix the four spring-loaded Allen key screws using the supplied tool and you’re done

Pre-applied NT-H2 thermal compound
Noctua’s much-acclaimed NT-H2 is a pro-grade TIM solution that provides minimum thermal resistance and outstanding long-term stability. Having the paste pre-applied to the heatsink base ensures optimal bond-line thickness and saves precious time in installation. Ideal for system integrators

6-year manufacturer’s warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. True to this legacy, the NH-D9 TR5-SP6 4U heatsink is built to last, and like all Noctua fans, the supplied NF-A9 units feature an MTTF rating of more than 150,000 hours. The entire package comes with a full 6-year manufacturer’s warranty
