This system will run without a fan, however a small fan is provided to improve system life. If desired, the user may remove the fan if operating in a normal room temperature of 25 C ( 77 F) or lower. The BIOS does not support variable fan speed vs. temperature.
Note -> Care should be taken when attaching a VGA cable, the connector is unsupported by the case, only supported by a riser off the board.
Tip -> The board does not include a speaker, but the board does include a standard 4-pin speaker connecter for an inexpensive piezo speaker if desired.
Tip -> Testing indicates that the video sub-system will be powered down if no VGA/HDMI monitor is attached at POST. There does not appear to be a BIOS setting for this feature.
BIOS Setup for Auto-Power-On after Power Failure:
On startup press the <DEL> key to enter the BIOS Setup, go to “Advanced” → “Power Management Configuration” . Make the following change…
Restore AC Power Loss → Power On
