2. The CPU fan did not rotate immediately upon system boot-up
or it took some time before the CPU fan rotated.
If the CPU fan did not rotate immediately upon system boot-up
or it took some time before the fan rotated, check whether the
heatsink and fan are mounted properly onto the CPU then
restart the system. If the same problem occurs, you must replace
it with a good quality fan - one that will rotate immediately once
power comes in and also one that can dissipate heat more
efficiently, otherwise, you have to disable this function in the CPU
Fan Protection field (PC Health Status submenu) of the BIOS.
2.3 Using the CPU Temperature Protection
Function
The CPU Temperature Protection function has the capability of
monitoring the CPUs 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 CPUs 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.
