A fan is a powered electromechanical component that is used to create fluid flow, primarily for the a cooling purposes inside of an electrical system.
Thermal Interface Material [TIM]
Any material that is inserted between two components in order to enhance the thermal coupling between them. A common use is heat dissipation, in which the TIM is inserted between a heat-producing device (e.g. an integrated circuit) and a heat-dissipating device (e.g. a heat sink).
