A computer housing temperature control device is disclosed. The present invention obtains the PWM signal generated from the CPU in the motherboard to control the rotation speed of all cooling fans located in the computer housing. Furthermore, the present invention uses a hub to share the PWM signal to all cooling fans in the computer housing, and the PWM signals are displayed on a screen in a digital or analog way. The PWM signal is issued by the motherboard according to the temperature of the CPU, and is used for controlling the rotation speed of the cooling fan so that the temperature of the computer housing is controlled well, and the user is informed of status of the computer.
