Cooling Fans
Voltage Selector Switch
Two cooling fans in your system provide proper ventila-
tion to cool system components and prevent overheating.
One fan is in the power supply. The second fan is next to
the Pentium™ processor, inside the system. For proper
ventilation, keep these areas clear.
The voltage selector switch sets the voltage for your sys-
tem to 115 volts (V) or 230 V. Be sure that the switch is
set correctly for the voltage in your area. Most outlets in
the United States, Canada, and Taiwan are 115 V. Most
outlets in Europe, Australia, and Asia are 230 V.
