Thermal Paste will last aroundone to two years, depending on different conditions, when inside the tube. When stored in an air-tight, dry, and cool place, it can even last couple more years.
Furthermore, thermal paste’s life span can vary depending on its quality and the components used to manufacture them. However, it is not recommended to use a thermal paste that is more than five years old.
How Long Does Thermal Paste Last on CPU/GPU
The thermal paste on either CPU or GPU generally lasts abouttwo to four years, depending on the heat generated by the chip.
Before considering that your parts need a fresh thermal paste, always check the CPU and GPU temperature. If your CPU and GPU have high-temperature readings, it may be that the paste is not working as it is supposed to.
Here are some things that affect a thermal paste’s life span:
