        abstract = {Many modern-day applications rely on heat sinks for heat dissipation. Pin fins are one of the heatsinks that are used for cooling and the convection coefficient of a pin fin depends on many parameters that need optimization. The pin fin in its plain form isn{\^a}??t efficient enough and there are ways to not only enhance its heat transfer rate but also reduce its weight simultaneously. This study aims to geometrically modify a plain pin fin to enhance the effective area for convective heat transfer. This study contains a comprehensive comparison between simple pin fin heatsinks and their corresponding heatsinks with helical-shaped profiles on the outer surface. A helical pattern was made using different pitches 2, 4, 6, and 8{\^A} mm and they were tested at air speeds of 2, 4, 6 and 8{\^A} m/s. Computational fluid dynamic analysis was performed to measure the performance of heatsinks. The tetrahedral mesh was used for simulation, and it was concluded that the helical fin having a 2{\^A} mm pitch performed the best and therefore had the highest convection coefficient of 202.69 W/m2K at 8{\^A} m/s airspeed. {\^A}{\copyright} Institute of Technology PETRONAS Sdn Bhd (Universiti Teknologi PETRONAS) 2024.}
