“…Besides liquid cooling techniques considering nanofluid particles, properties of nanofluid particles, heat sink geometry, fin and base thickness of the heat sink, cooling fan and form factor of CPU chassis are also investigated by many researches. Azwadi et al, [5] simulated the thermal management of Advanced Technology Extended (ALX) and Balanced Technology Extended (BTX) by using ANSYS and claimed that BTX form factor is better than ATX form factor. Yu and Webb [6] used CFD (Icepak) to identify a cooling solution for desktop computer, by using an 80W CPU.…”

During its operation CPU dissipates undesirable heat. Therefore, heat sink is very essential in modern computing system to absorb extra heat dissipated by the CPU. Forced convection air cooling is common approach. In the present work, a steady-state convective heat transfer process is analyzed for CPU cooling. A rectangular fin heat sink equipped in a computer chassis is numerically investigated and simulated using the software ANSYS CFX. A two-equation based turbulence model is chosen to capture the turbulence of the flow inside the domain. The overall dimension of the heat sink is optimized for three different parameters of the heat sink such as fin quantity, fin height and baseplate thickness. An optimum fin quantity, fin height and baseplate thickness are found, and, respectively. Two different orientations of fins are also compared. Better thermal performance is achieved when the fin channel is perpendicular to the surface parallel to the outlet. The average temperature of the heat sink is found. It is also predicted that the heat sink studied here is capable to keep the CPU temperature underthat is reasonably acceptable.
