Non-prismatic radial folded fin heat sinks include fin arrays comprised of folded fins joined to a thermally conductive central core. The fin arrays can have either a constant or variable bend radius. The non-prismatic radial folded fins can be made by stamping patterns into sheet metal prior to folding the sheet metal in opposite directions at various intervals to form outer and inner folds. By arranging the fins in a non-prismatic radial pattern around the central core, airflow generated by an overhead fan is better utilized, thus improving the cooling effect of the device.
