Both Sensor and No-sensor Fan Connectors support CPU/AGP/Sys-
tem/Case cooling fan with +12V mode. When connecting the wire to
any Fan Connector, user should make sure that the red wire is for the
positive current and should be connected to pin +12V, and the black
wire is Ground and should be connected to pin GND.
A Hardware Monitor chipset is on board, with which user can install a
Hardware Monitor Utility and read the fan speed transmitted from the
sensor fan. Otherwise, user can read the fan speed from the "Hard-
ware Monitor Status" in CMOS BIOS.
A running Fan will send out 2 electric pulses per rotation of its fan
blade. A Sensor Fan Connector will count the electric pulses and send
the information to the System Hardware Monitor which in turn will work
out the fan rotation speed and display it with the monitoring program.
