Update
Natural Convection: 4.72 based on 70 C temp rise above ambient
Thermal resistance is calculated based on a single 1" (25.4mm) square heat source centered on the heat sink. If
you have distributed loads, then you can expect 10% better performance in natural convection and 20% better
performance in forced convection.
