CPU Temperature Protection
The CPU Temperature Protection function has the capability of
monitoring the CPU’s temperature during system boot-up.
Once the system has detected that the CPU’s temperature ex-
ceeded the temperature limit defined in the BIOS, 5 warning beeps
will sound then the system will automatically power-off.
Check whether the heat sink and fan are mounted properly onto
the CPU because high CPU temperature may be due to incorrect
fan / heat sink installation. Now restart the system. If the same
problem persist, it may be 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.
