常见问题

What is the difference between thermal pads and thermal grease?

Thermal pads are solid, pre-formed sheets with consistent thickness, easier to apply and rework. Thermal grease is paste-like, requiring precise application but typically offers better thermal performance by filling smaller gaps.

How often should thermal interface materials be replaced?

Typically every 2-5 years or during maintenance cycles, as materials can dry out, pump out, or degrade, reducing thermal performance over time.

Can thermal pads be reused?

Generally not recommended as compression and material degradation reduce effectiveness; fresh materials ensure optimal thermal contact.
