Award BIOS Setup Utility
CPU Fan Protection
The CPU Fan Protection function, when enabled, has the capability of
monitoring the CPU fan during system boot-up and will automatically
power-off the system once it has detected that the CPU fan did not
rotate. Set this field to Disabled if you are not using this function. Refer
to CPU Fan Connector with CPU Fan Protection Function in chapter
2 for more information.
CPU Temp. Prot. Function and CPU Temp. Prot. Alarm
The CPU Temperature Protection function has the capability of
monitoring the CPUs temperature during system boot-up. To use this
function, set the CPU Temp. Prot. Function field to Enabled then select
the desired CPU temperature limit in the CPU Temp. Prot. Alarm field.
Once the system has detected that the CPUs temperature exceeded
the limit, 5 warning beeps will sound and at the same time, a warning
message will appear on the boot-up screen instructing you to press
<Del> in order to enter the main menu of the BIOS. If you did not
press <Del>, the system will automatically power-off after the 5
warning beeps. You may either:
1. Press <Del> then enter a new CPU temperature limit;
or
2. Allow the system to power-off after the 5 warning beeps then
check whether the heatsink and fan are mounted properly onto the
CPU because high CPU temperature may be due to incorrect fan/
heatsink installation. Now restart the system. If the same problem
persist, it may be that the CPU fan is damaged or it is not rotating
properly. Try replacing it with a new fan. If it is due to other
contributing factors that resulted to high CPU temperature, you
may need to set a lower CPU temperature limit.
CPU Temperature References
When you power-up a system, the BIOS message appears on
the screen and the memory count begins. After the memory test,
the CPU temperature range is normally between 32
o
C and
35
o
C. When you run an operating system then tried to reboot
the system, the CPU temperature range at this time is between
40
o
C and 45
o
C. These temperature references serve as a guide
when you select the CPU temperature limit.
