CPU and System Fan Connector
Plug the CPU fan cable to the 3-pin CPUFAN1 connector. If you have chassis fan,
you can also plug it into SYSFAN2.
Please insert the 4-pin connector as illustrated in case your model requires the connection
of a CPU fan (CPUFAN) and system fan (SYSFAN) connectors.
Note: If you're using Windows ME or Win 2000 OS, because the default setting of
"Energy Lake" function in the EPC BIOS is enable , you will see in your "System
Manager" an "Unknown Device"; if you do not wish to see this message, please set the
"Energy Lake" function to disable.
