Fan Headers

The function/operation of the fans is as follows:

The fans are on when the board is in the ACPI S0 or S1 state.

The fans are off when the computer is in the ACPI S3, S4, or S5 state.

Each fan header is wired to a tachometer input.

All fan headers support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed.

All fan headers have a +12 V DC connection (up to 12 V DC when using 3-wire chassis fans.

All fan headers are controlled by Pulse Width Modulation.

The front and rear chassis fans support Linear Fan Control on 3-wire fans.

The Desktop Board has a 4-pin processor fan header and two 4-pin chassis fan headers compatible with 4-wire and 3-wire chassis fans.

LAN Wake Capabilities

CAUTION

For LAN wake capabilities, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply.

LAN wakeup capabilities enable remote wake-up of the computer through a network. The LAN subsystem monitors network traffic and upon detecting a Magic Packet* frame, it asserts a wake-up signal that powers up the computer.

Instantly Available PC Technology

CAUTION

For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to- RAM) sleep state. Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off and the front panel power LED will behave as configured by the BIOS “S3 State Indicator” option). When signaled by a wake-up device or event, the system quickly returns to its last known wake state. When signaled by a wake-up device or event, the computer quickly returns to its last known awake state.
