ABSTRACT:
A method of cooling computer components is provided. The method comprises positioning the fan adjacent computer components so that the fan is in a position to blow air over the computer components, connecting the fan to a first voltage source through a zener diode voltage divider, connecting the fan to a first voltage source through a switch, manipulating the switch into a first position wherein a first voltage is applied to the fan thereby inducing the fan to operate at a first speed and manipulating the switch into a second position wherein a second voltage is applied to the fan thereby inducing the fan to operate at a second speed which is less than the first speed.
