Cooling effectiveness using a cooling fan on an electronic device becomes a benchmark. Speaker- based synthetic jets that are becoming innovations today work on the principle of zero input mass, producing air in the cavity with an oscillating membrane which results in the suction phase occurring in the orifice hole. The generated air then flows through the orifice to pound the heat source as a forced convection cooler. Speakers used as oscillating actuators resemble waveforms using sine, square, and triangular wave functions with frequencies of 80, 100, and 120 Hz. Air flow simulation created using Fluent CFD. The use of wave variations has different characteristics. Triangular waves indicate the final test temperature reaches 27oC, with an optimum frequency of 80 Hz. Air flow created in the form of vortex flow with a type of turbulent flow. The electric power consumption of cooling fans reaches ten times the consumption of synthetic jet power.
