Based on lab test data, the case-to-ambient (Ψ
CA
) performance of heatsink was found
to be 0.356 °C/W with 18 CFM of airflow through the heatsink fins. This will allow a
maximum T
LA
of 39 °C and meet the processors Thermal Profile specification as
described in the processor datasheet. The estimated performance for additional
airflows is shown in Figure 12.
