Fan Speed Control Monitor
This feature allows the user to decide how the system controls the speeds of the
onboard fans. The CPU temperature and the fan speed are correlated. When the
CPU on-die temperature increases, the fan speed will also increase for effective
system cooling. Select "Full Speed/FS" to allow the onboard fans to run at full
speed for maximum cooling. The FS setting is recommended for special system
confi guration or debugging. Select "Performance/PF" for better system cooling.
Select "Balanced/BL" for the onboard fans to run at a speed that will balance the
needs between system cooling and power saving. The BL setting is recommended
for regular systems with normal hardware confi gurations. Select "Energy Saving/ES"
for best power effi ciency and maximum quietness. The Options are:
Full Speed/
FS
, Performance/PF,
Balanced/BL
, and Energy Saving/ES.
