You can set the time for the clock and the CMOS values by using the Setup program described in

1.3.18 Power Supply Fan
For cooling, a fan is attached to the power supply at the rear of the computer chassis. This fan draws air
in through the front of the chassis and exhausts air out the rear of the chassis. This provides air flow
across the processor.
1.3.19 Speaker
An internal piezo speaker is mounted on the system board. The speaker provides audible error code
information (beep codes) during the power-on self-test (POST) and as required by the software. See
