The Design of Experiments (DOE) framework was used to study the effects of fan speed control and physical
placement on a hybrid PC system. Three factors and three levels were considered in the experiment. The ideal
conditions for effective cooling were determined, and the results were obtained by running the design in Minitab.
Workload is found to be the primary driver of temperature increases in hardware, as expected. Fans exert secondary
influence by helping cool the PC components. Despite its limited impact, physical placement also shows statistical
significance in helping cool the PC. Good airflow around a PC placed on a trolley yielded the best cooling for the PC
components. Residual analysis confirmed model adequacy. This result confirms that environmental factors, such as
PC placement, have a meaningful impact on thermal behavior and should be incorporated into the hardware cooling
strategy.
