BIOS Setup
H/W Monitor
This section shows the status of your CPU, fan, overall system status, etc.
Monitor function is available only if there is hardware monitoring mechanism onboard.
CPU Shutdown Temperature
If the CPU temperature reaches the upper limit preset in this setting, the system will be
shut down automatically. This helps you to prevent the CPU overheating problem.
Setting options: [75
O C], [80 O C], [85 O C], [Disabled].
CPU Fan Failure Warning
W hen enabled, the system will automatically monitor the CPU fan during boot-up. If it
detects that the CPU fan is not rotating, the system will show an error message on
the screen and halt the boot-up process. The function is built with CPU fan power
connector (CFAN1) only and enables you to protect the CPU form possible over-
heating problem. If you don
’t connect the CPU fan to the CPU fan power connector,
we recommend disabling the feature. Settings: [Enabled], [Disabled].
Smart Fan
W hen the current temperature of the CPU fan reaches the value you specify here,
the CPU fan will speed up for cooling down to avoid the CPU damage; on the contrary,
if the CPU fan current temperature is lower than the specified value, the CPU fan will
slow down its speed to keep the temperature stable. Setting options: [Disabled],
[40
O C], [50 O C], [60 O C].
Smart Fan Tolerance
You can select a fan tolerance value here for the specific range for the Smart Fan
item. If the current temperatures of CPU fan reach to the maximum threshold (the
temperatures set in the Smart Fan plus the tolerance values you set here), the fans
will speed up for cooling down. On the contrary if the current temperatures reach to
the minimum threshold (the set temperatures minus the tolerance values), the fans
will slow down to keep the temperatures stable. Setting options: [1
O C ~ 5 O C].
