GPU Switch (Extra Setting)
You can use the GPU Switch to select either MSHybrid
or Discrete graphics mode. You must click OK after
changing the setting to restart the system (make sure you
have saved any work in progress before restarting).
Fan (System Monitor)
You can set the fan speed to Maximum (full power), Au-
tomatic or Custom from this menu item. The fan speed
will adjust itself automatically to control the heat of the
CPU/GPU. You can use the Offset slider to adjust the set-
tings to your preference. However you can adjust the set-
ting to Maximum if you prefer.
The Custom setting allows you to click and drag on any
of the 2 midrange nodes on the graph in order to adjust the
temperature parameters of the CPU Fan or GPU Fan.
All these settings can be overidden by the system, as a
safety precaution, if it requires heavier use of the fan.
