Abstract The uneven temperature distribution resulting from thermal stresses in heat sinks is a significant issue modern electronic devices. This numerical investigation utilizes fluid to analyze the cooling, flow, and transfer characteristics of eight different sink designs. These include pin–fin with circular, triangular, square, hexagonal cross-sections, as well their perforated versions. results show that resistance range for all geometries was between R th = 0.29 0.51 K W −1 . circular cross-section pin structure found be most efficient terms resistance, while triangular least efficient. narrow low indicates high cooling potential sink. It has been observed studied 308.732 315.273 K. homogeneous 308.73 311.306 pin-type square attained maximum Performance Evaluation Criteria (PEC) 1.1872 at P 689 Pa, lowest PEC 0.67 2750 Pa. revealed that, relation PEC, structures had superior performance compared other designs, except square-section structure. research measuring efficiency based just on or average not enough; criteria must also taken into account.
