Thermal Interface Material (TIM) is a thermally conductive compound or pad used to enhance heat transfer between electronic components and heat sinks in multi-core processors.

TIM is critical because even finely machined surfaces have microscopic gaps that trap air, a poor thermal conductor. Without TIM, these air pockets create high thermal resistance, causing processor cores to overheat, throttle performance, or fail prematurely under heavy computational loads.
In stable industrial environments, high-quality TIM typically lasts 3-5 years. Replacement is recommended if processor temperatures rise abnormally, during maintenance cycles, or if the system is exposed to thermal cycling that may degrade the material (e.g., pump-out or dry-out effects).
Thermal paste is a viscous compound that offers low thermal resistance by filling gaps thinly but requires precise application. Thermal pads are pre-formed solid sheets easier to install and electrically insulating, but generally have higher thermal resistance. Paste is preferred for maximum performance; pads for ease and safety in gap-filling.
