Heat Sink Calculators

Use our heat sink calculators to estimate the required heat sink dimensions, understand the performance properties of heat pipes, and calculate the thermal resistance & temperature rise of both standard and vapor chamber based heat sinks.

Heat Sink Size Calculator

Estimates required heat sink volume & dimensions based on power input, Tcase, ambient temperature and available airflow. Useful during early design phase.

Heat Sink Performance Calculator

Compare heat sinks using a solid metal base to those using a vapor chamber base: heat sink thermal resistance & delta-T for each part of the heat sink.

Heat Pipe Calculator

Calculates heat pipe carrying capacity (Qmax) and thermal conductivity based on power input, heat pipe length, diameter, orientation, & condenser/evaporator sizes.
