AM5 Edition with thermal paste guard

When the mounting pressure of the cooling solution is applied, excess thermal paste will be squeezed outwards. With AM5 CPUs, this excess paste tends to accumulate in the cut-outs at the sides of the heatspreader and may become difficult to remove. Simple to apply, the NA-TPG1 prevents this undesired phenomenon.

Easy to clean
NT-H1 is one of the easiest to clean thermal compounds on the market: Simply wipe it off the CPU and heatsink with a dry tissue or paper towel, then wipe them clean with a moist tissue or towel. No cleaning alcohol or solvent required!

Not electrically conductive, non-corroding
While some high-end thermal compounds and pads are risky to use due to their electrical conductivity or corroding properties, there's no risk of short-circuits with NT-H1 and it's completely safe to use with any type of CPU cooler, regardless of whether it's made from copper or aluminium and whether it's nickel-plated or not.

Excellent long-term stability
NT-H1's unique formula is highly stable over time, even after longer periods of usage. It can be stored at room temperature for at least 3 years and due to the compound's exceptional curing, bleeding, dry-out and thermal cycling characteristics, it can be used on the CPU for 5 years or more.

3.5g package for 3-20 applications 3.5g package for 3-20 applications
Sufficient for around 3-20 applications (depending on the size of the CPU or GPU, e.g. around 3 applications for large CPUs such as TR4, 15 for AM4/AM5 or LGA1700, and around 20 for small CPUs such as LGA1151), the classic 3.5g packaging size is ideal for most users who only install coolers every now and then.

 

Easy to apply

Thanks to its excellent spreading properties, there is no need to manually spread NT-H1 before installing the cooler: Simply apply some paste onto the CPU (see instructions for details), put on the heatsink and you're ready to go!

LOADING...

Noctua NT-H1 3.5g AM5 Edition is thermal compound for transferring heat from a CPU or GPU to its heatsink, bundled with an NA-TPG1 guard to help keep AMD AM5 Ryzen CPUs clean during application. It suits PC builders and maintainers who want an easy-to-apply paste, especially for AM5 systems.

Recommended For

  • AM5 PC builders who want to keep excess paste out of the heatspreader’s side cut-outs during a CPU-cooler installation; the included NA-TPG1 guard is designed for that cleanup task.
  • DIY builders replacing a CPU cooler or refreshing CPU paste who prefer a simple application: Noctua recommends applying dots and mounting the cooler without manually spreading the compound first.
  • AM4 and Intel desktop CPU owners who need thermal paste for a cooler installation or repaste; the NT-H1 application guide covers these CPU sizes and platforms, though the AM5 guard is not intended for them.
  • Desktop PC owners who want to avoid frequent preventive repasting; Noctua specifies up to five years of use on the CPU and says replacement is not necessary without a clear temperature increase.

Real-World Use Scenarios

  • When building an AM5 PC, apply NT-H1 and fit the cooler with the included NA-TPG1 guard in place; it helps keep excess paste out of the heatspreader cut-outs and makes installation less messy.
  • When replacing or reinstalling a cooler on an AM5 CPU, the paste guard helps limit buildup in the processor’s edge cut-outs, which can otherwise be harder to clean after repeated paste applications.
  • When installing an air cooler or liquid-cooler cold plate on a CPU, apply the paste and mount the cooler without manually spreading it first; Noctua says NT-H1 spreads under cooler installation pressure.
  • When removing a CPU cooler for maintenance or an upgrade, NT-H1 can be wiped from the CPU and cooler with a dry tissue or paper towel, so a separate cleaning solvent is not required for routine cleanup.
  • For occasional PC builds or cooler changes, the 3.5g tube can cover multiple CPU applications, so one pack may be useful across several maintenance or upgrade jobs.
