We recommend changing the thermal paste every year, especially if the computer is used intensively. If the processor temperature becomes abnormally high, it’s a sign that it’s time to replace it.
If your computer is close to 80°C when idle, it’s high time to replace the thermal paste.
Are you hesitating between pad and thermal paste?
Thermal pads are often used when components heat up very little, as is the case with some NVMe SSDs. They’re also preferred for their ease of installation and reusability, unlike thermal paste, which requires replacement with each application.
For advice on choosing between a thermal pad and thermal paste.
