Cooling system

Abstract

A cooling system includes a cooling fan and a BIOS (Basic Input Output System) chip. The cooling fan includes a cable and a control chip. The control chip stores a manufacturer's name or a manufacturer's code of the cooling fan. The BIOS chip stores a plurality of manufacturers' names and/or manufacturers' codes and a plurality of control curves. The BIOS chip reads the manufacturer's name and/or the manufacturer's code stored in the control chip through the cable and the connector, and transmits a control curve corresponding to the manufacturer's name and/or the manufacturer's code to the control chip. The control chip controls the cooling fan according to the control curve.

What is claimed is: 
     
         1 . A cooling system comprising:
 a cooling fan comprising:
 fan blades; 
 a driver to drive the fan blades; 
 a connector connected to a motherboard; 
 a cable; and 
 a control chip connected to the connector through the cable, and connected to the driver, wherein the control chip stores a manufacturer's name and/or a manufacturer's code of the cooling fan; and 
   a BIOS (Basic Input Output System) chip storing a plurality of manufacturers' names or manufacturers' codes and a plurality of control curves, wherein each manufacturer's name or manufacturer's code corresponds a control curve; wherein the BIOS chip reads the manufacturer's name and/or the manufacturer's code stored in the control chip through the cable and the connector, and transmits a control curve corresponding to the manufacturer's name and/or the manufacturer's code to the control chip, the control chip controls the cooling fan according to the control curve.   
     
     
         2 . The cooling system of  claim 1 , wherein the cable comprises a speed wire, a power wire, a ground wire, a pulse wire, and an information wire, the speed wire transmits speed data of the cooling fan to the BIOS chip, the power wire and the ground wire transmit power to the control chip, the pulse wire transmits pulse width modulation signals from the BIOS chip to the control chip for controlling the cooling fan, the information wire transmits the manufacturer's name and/or the manufacturer's code stored in the control chip to the BIOS chip.
