Hardware Setup

Fan Power Connectors: CPUFA/SYSFA

The CPUFA (processor fan) & SYSFA (system fan) support system cool-
ing fan with +12V. It supports three-pin head connector. When connecting
the wire to the connectors, always take note that the red wire is the positive
and should be connected to the +12V, the black wire is Ground and should be
connected to GND. If the mainboard has a System Hardware Monitor chipset
on-board, you must use a specially designed fan with speed sensor to take
advantage of the CPU fan control.
