Mounting kit Noctua NM-TR5-SP6 for SP6 sTRX5 sWRX9 processors

The Noctua NM-TR5-SP6 is a SecuFirm2™ mounting kit that enables fitting Noctua DX-4677, DX-4189, DX-3647 and TR4-SP3 series coolers to AMD TR5/SP6 sockets (sTRX5/sWRX9) used with Epyc server and Threadripper workstation CPUs. The kit is supplied in compact packaging and comes in a metallic colour. Brackets and springs have been updated to meet the increased pressure requirements of the TR5/SP6 socket while maintaining compatibility with the mentioned Noctua coolers.

Advantages

The mounting kit provides a secure SecuFirm2™ mounting solution for AMD SP6/sTRX5/sWRX9 platforms, with reinforced brackets and springs adapted for higher contact pressure. Installation follows the familiar Noctua procedure: position the heatsink, tighten the four spring-loaded Allen screws with the supplied tool and complete the mounting quickly. The kit preserves compatibility with Noctua’s DX-4677, DX-4189, DX-3647 and TR4-SP3 cooler series.

How to use

Place the heatsink on the processor aligned with the socket and the mounting holes. Use the supplied Allen key tool to tighten the four spring-loaded screws until the heatsink sits evenly and securely. The spring-loaded screws ensure correct contact pressure when mounting on TR5/SP6 sockets. Follow standard thermal paste application and motherboard manual instructions for safe installation.

Recommendations

Use the NM-TR5-SP6 only with the listed Noctua cooler series and on compatible SP6/sTRX5/sWRX9 sockets. Apply an appropriate amount of thermal paste and tighten screws evenly in a cross pattern to ensure uniform pressure. Do not overtighten; follow torque guidance from the cooler or motherboard documentation where available.
