4.4. Heat Sink

The following equations show how to determine power when using a heat sink.

You can obtain the θJC value that is specific to the FPGA from the data sheet. The θCS value refers to the material that binds the heat sink to the FPGA and is approximated to be 0.1 °C/W. You can obtain the θSA value from the manufacturer of the heat sink. Ensure that you obtain this value for the right conditions for the FPGA which include analyzing the correct heat sink information at the appropriate airflow at the device.
