select the CPU Temp. Limit of OFF option and enter a decimal number between 000 and
127. The temperature range is specified below.
Minimum Value: 0°C
Maximum Value: 127°C
CPU Temp. Limit of Start [020]
WARNING:
Setting this value too high may cause the fan to start only when the
CPU is at a high temperature and therefore cause the system to be
damaged.
The CPU Temp. Limit of Start option can only be set if the CPU FAN Mode Setting
option is set to Automatic Mode. Use the CPU Temp. Limit of Start option to select the
CPU temperature at which the cooling fan should automatically turn on. When the fan
starts, it rotates using the starting pulse width modulation (PWM) specified in the Fan 3
Start PWM
option below. To select a value, select the CPU Temp. Limit of Start option
and enter a decimal number between 000 and 127. The temperature range is specified
below.
Minimum Value: 0°C
Maximum Value: 127°C
CPU Fan Start PWM [070]
The Fan 3 Start PWM option can only be set if the CPU FAN Mode Setting option is set
to Automatic Mode. Use the Fan 3 Start PWM option to select the PWM mode the fan
starts to rotate with after the temperature specified in the Temperature 3 Limit of Start is
exceeded. The Super I/O chipset supports 128 PWM modes. To select a value, select the
Fan 3 Start PWM
option and enter a decimal number between 000 and 127. The
temperature range is specified below.
