Frequently Asked Questions

AI
Depending on the quality of the compound and your system's heat output, most users should consider reapplying every 2 to 5 years, or whenever you notice a significant rise in operating temperatures.
Metal-based conductive pastes can cause short circuits if they spill onto the motherboard. For most users, non-conductive ceramic or carbon-based pastes are the safer, recommended choice.
Yes. Too little paste leaves air gaps, while too much can create a thick layer that actually insulates the chip. A pea-sized amount is the standard recommendation for most CPUs.
