How long can I use the thermal paste once opened?
The NT-H1 and NT-H2 can be used for up to 2 years once opened. The paste can be stored at normal room temperature, but avoiding places that tend to get hot is recommended, else it would dry more quickly.
Our recommendation:
- Tightly close the cap after each use.
- Store the thermal compound protected from extremely hot or cold temperatures.
- Do not expose our thermal compound to direct sunlight.
