Allows you to set the low speed limit of the CPU fan and the system sends warning
message when the fan speed drops below the set value.
Conguration options: [Ignored] [200 RPM] [300 RPM] [400 RPM] [500 RPM]
[600 RPM]
CPU Fan Profile [Standard]
Allows you to set the appropriate performance level of the CPU fan.
[Standard] Sets to [Standard] to make the chassis fan automatically adjust
depending on the CPU temperature.
[Silent] Sets to [Silent] to minimize the fan speed for quiet CPU fan operation.
[Turbo] Set to [Turbo] to achieve maximum CPU fan speed.
[Manual] Sets to [Manual] to display more items for you to manually adjust the
