The 8-bit Digital I/O (DIO) connector allows for input/output signals of digital logical states
defined by voltage levels.
Jumper Setting
DIO signal and power can be configured via jumper settings as previously instructed in this
chapter.

These fan connectors are used to connect to cooling fans. Cooling fans provide adequate air
circulation throughout the chassis and dissipate heat to prevent overheating of the system
board and components. The 4-pin fan provides PWM to modulate fan speed whereas the 3-pin
fans modulate fan speed via voltage modulation.
BIOS Setting
Configure the Smart Fans in the Advanced menu ("SIO NUVOTON6116D" submenu) of the
BIOS. Refer to chapter 3 for more information.
