PURPOSE: An apparatus for controlling a cooling fan of a plasma display panel is provided to improve the quality of display by minimizing a fan noise and an electric power consumption. CONSTITUTION: An apparatus for controlling a cooling fan of a plasma display panel includes a first temperature sensing unit(11) sensing an external temperature, a second temperature sensing unit(12) sensing an internal temperature, a first comparing unit(21) outputting a comparative signal by comparing the difference between the external and the internal temperatures sensed by the first and the second temperature sensing units, a second comparing unit(22) outputting a detective signal by detecting a rose value of the internal temperature detected by the second temperature detecting unit, a controller controlling a plurality of fan driving motor(51,52,53) respectively according to the output level from the first and the second comparing units.
