Next-generation performance

Further improving the award-winning NT-H1, NT-H2 uses a new, fine-tuned mixture of metal oxide micro-particles for even lower thermal resistance and reduced bond-line thickness at typical mounting pressures. This allows it to achieve even better performance in most application scenarios.

Easy to clean with included wipes
The 3.5g pack of NT-H2 includes three large NA-CW1 cleaning wipes that are pre-moistened with an isopropyl alcohol mixture and make it child's play to remove: Simply wipe off the paste from the CPU and the base of the cooler using one of the wipes and you're done!

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-H2 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-H2 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
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 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-H2 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!

Noctua NT-H2 is a premium 3.5g thermal paste for PC builders and upgraders who want to transfer heat from a CPU or GPU to its heatsink; it suits air- and liquid-cooled systems and includes three cleaning wipes.

Recommended For

  • Desktop PC builders replacing or applying paste during a CPU cooler installation who want a non-conductive compound that spreads under cooler pressure without manual spreading.
  • PC owners refreshing a desktop CPU’s thermal interface who want a paste Noctua rates for up to five years of use and includes cleaning wipes for removal.
  • Enthusiasts comparing standard CPU pastes who want strong tested performance and understand that temperature differences between high-end compounds can be small and setup-dependent.
  • Occasional PC maintainers handling a few CPU applications who want a small tube with cleanup wipes; the 3.5g pack is rated for about 3–20 applications depending on CPU size.

Real-World Use Scenarios

  • When building a desktop PC or installing a new CPU cooler, apply NT-H2 between the processor and heatsink; its spread-under-mounting application means you do not need to manually spread it first.
  • When refreshing a desktop CPU’s thermal interface during cooler removal or maintenance, clean off the old compound and apply NT-H2; the included wipes make cleanup easier, and Noctua specifies up to five years of use on a CPU.
  • For a high-load desktop CPU, such as one used for rendering or stress tests, NT-H2 can serve as the interface between the CPU and cooler; any temperature improvement depends on the processor, cooler, mounting, and prior paste, and may be small on lower-power CPUs.
  • When servicing a graphics card whose cooler is already being removed, an experienced user can replace the paste on the GPU die with NT-H2; the result depends on correct contact and reassembly, so a temperature drop is not guaranteed.
  • For laptop maintenance, NT-H2 may be used when the heatsink is removed, but it is not a guaranteed long-term fix: Noctua warns that some laptop designs can experience pump-out, which may reduce the benefit over time.
