2.2 Using the CPU Temperature Protection
Function
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 (PC Health Status submenu of the BIOS). 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.
