3-7 CPU Overheating Protection
This mainboard is equipped with CPU Overheating Protection. It will automati-
cally remove power to shutdown the system when CPU temperature reaches
approximately 110°C. This is to prevent long term damage to the CPU from
overheating. When this happens, the speaker produces a sustained beep sound
and the system will not be able to power on. This protection is designed
through hardware and no BIOS setup is required
To power on your system again normally,
Step 1 : Unplug the ATX power cord (or turn off the ATX power supply
switch)
Step 2 : Wait a few minutes for the CPU to cool.
Step 3 : Check that the CPU heatsink and cooling fan assembly is properly
installed.
Be careful when touching the heatsink as it may be hot.
Step 4 : Plug back the ATX power cord (or turn on the ATX power supply
switch) and power -on the system.
If the beeping sound persists, repeat Step 1 to remove the power source.
Note :
The CPU Overheating Protection will function only if the CPU
is designed with an internal thermal diode. AMD Athlon XP
or later CPUs is equipped with internal thermal diode.
