Premium thermal compound for CPU and GPU

Noctua NT-H2 is a second-generation hybrid paste formulated with micro-particles to improve heat transfer from the processor or graphics chip to the cooler. The 3.5 g syringe contains enough material for roughly three to twenty applications depending on die size. It is non-conductive and non-corrosive, removing the risk of short circuits on any heatsink type.

Upgrade path from older pastes

The compound replaces aged or basic thermal grease that has dried out or lacks the particle density to fill microscopic surface gaps. A switch is worthwhile when temperatures under load remain high despite adequate airflow or when a cooler is reseated after maintenance. The included NA-CW1 cleaning wipes simplify complete removal of the previous layer before fresh application.

Build integration and longevity

No spreading is required before mounting the heatsink; pressure during installation distributes the paste evenly across the die. The formula remains stable for up to five years on the CPU and can be stored for up to three years unopened. This frees the builder from frequent re-pasting cycles and suits both air and liquid cooling loops without specific clearance or power requirements.

Questions about this item

What size CPUs can the 3.5g tube cover and how many applications does it provide?

The 3.5g pack yields around 3 to 20 applications depending on CPU size, for example roughly 3 applications for TR4 sockets and around 20 for LGA1151 processors.

Does the paste need to be spread manually before mounting the heatsink?

No, the compound is designed for easy application without pre-spreading; simply place a suitable amount on the CPU and the heatsink pressure will distribute it evenly.

How long can the paste stay effective on the CPU and how long can the tube be stored?

The manufacturer recommends a usage time of up to 5 years on the CPU and a storage time of up to 3 years for the tube.
