Pro-grade thermal compound for AM5 CPUs

Noctua NT-H1 3.5g AM5 Edition is a hybrid thermal paste designed for optimal heat transfer between CPU or GPU and heatsink. It has earned more than 150 awards and recommendations from international hardware outlets. The pack includes the NA-TPG1 thermal paste guard tailored for AMD Ryzen AM5 processors. The 3.5g syringe provides enough material for roughly 15 applications on AM5 sockets.

Thermals, noise and power in normal use

The compound delivers reliable thermal performance for air- or water-based cooling, overclocking or silent builds. Its formulation requires no spreading before heatsink installation and cleans easily with a dry paper towel or tissue, eliminating the need for cleaning alcohol. Long-term stability is rated for up to five years on the CPU and three years in storage.

Build fit: guard, sockets and applications

The included NA-TPG1 guard prevents paste build-up in the heatspreader cut-outs of AM5 CPUs during mounting pressure. The paste suits CPU and GPU applications across multiple platforms, with roughly 20 applications on LGA1200, 15 on LGA1700 and three on TR4. Buyers who need a larger volume for many builds or who prefer a paste without the AM5-specific guard should consider other options.

Questions about this item

How do I install the NT-H1 on my AM5 CPU and what is the common mistake to avoid?

Apply a pea-sized dot in the centre of the heatspreader and let the cooler pressure spread it; the included NA-TPG1 guard fits around the CPU to catch excess paste in the cut-outs, which is the step many builders skip.

When will I need to replace the NT-H1 on my Ryzen processor?

Noctua rates the compound for up to 5 years of continuous use on the CPU before re-application is recommended.

What limit appears first during sustained loads with this 3.5g tube?

The tube contains enough paste for roughly 15 applications on AM5, so the practical limit is the number of re-pastes you can perform before buying a new syringe.
