Cooling system for computing device

A method for controlling an operating temperature of a video graphics array (VGA) chipset, the method comprising:

• monitoring a rotational speed of a cooling fan installed on the VGA chipset, the rotational speed of the cooling fan being controlled by a fan power;
• monitoring a vital temperature a graphics processor of the VGA chipset;
• increasing the fan power when the vital temperature is substantially above a first threshold to increase the fan speed;
• decreasing the fan power when the vital temperature is substantially below the first threshold to decrease the fan speed;
• increasing the operating voltage of the processor when the vital temperature is substantially below a third threshold;
• and
• decreasing the operating voltage of the processor when the vital temperature is substantially above the third threshold.

A video graphics array (VGA) chipset with cooling system comprising:

• a graphics processor having an operating power controlled by an operating power control signal;
• a cooling fan for cooling the graphics processor;
• a fan input-output module electrically connected to the fan for transmitting a fan control signal to the fan, the fan control signal controlling the rotational speed of the fan;
• a controller electrically connected to the fan input-output module and the graphics processor, the controller comprising fan logic for generating the fan control signal based on a vital temperature of the graphics processorand outputting the fan control signal to the fan inputoutput module, and power logic for generating the operating power control signal based on the vital temperature of the graphics processor and outputting the operating power control signal to the graphics processor;
• and
• a temperature transducer connected to the graphics processor for measuring the vital temperature and outputting the vital temperature to the controller.
