Thermal Capacitance
Convection carries heat away from the heat sink. Fins on the heat sink increase its surface area and its convective efficiency. Forced air is often directed across the heat sink to increase convection. Some heat sinks use water to conduct heat away from a header connected to the chip and out to a radiator.

Selecting an Appropriate Heat Sink | DigiKey
As an alternative heat sink, selecting the 15 x 15 x 12.5 mm Ohmite BGAH150-125E with a greater surface area due to a greater fin height, reduces the total thermal resistance of the heat sink and TIM to 11°C/watt. This would lower the case temperature to about 67°C for about the same cost and provide a greater temperature margin.
