traditional 3-pin fans. (The speeds of
4-pin (PWM) fans are controlled by
Thermal Management via BIOS Hard-
ware Monitoring in the Advanced Set-
ting. (The default setting is Disabled.)
Note: Please use all 3-pin fans or all
4-pin fans on a motherboard. Please
do not use 3-pin fans and 4-pin fans
on the same board.

sis overheat. This LED will also blink
