Buying Guide: The Specs That Matter
Thermal Conductivity
From a data standpoint, higher W/mK moves heat faster; quality non-metal pastes drop temps a few degrees over stock, and liquid metal goes further for experts.
Conductivity and Safety
Looking at the numbers, non-conductive ceramic pastes are safe and easy; liquid metal performs best but can short components if it spills, so apply with care.
Application and Longevity
On specs, a pea-sized dot spreads under mounting pressure; good pastes resist drying for years before a reapplication is needed.
