Those connectors support CPU/System/Chassis cooling fan with
+12V. Those support three pin head connector. When connecting
the wire to FAN connectors, user should give attention 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 your
motherboard has Hardware Monitor chipset on-board, you must
use a specially designed fan with speed sensor to take advantage
of this function.
For fans with fan speed sensor, every rotation of the fan will send
out 2 pulses. System Hardware Monitor will count and report the
fan rotation speed.
NOTE 1: Always consult vendor for proper CPU cooling fan.
NOTE 2: CPU FAN supports the FAN control. You can install
PC Alert utility. This will automatically control the CPU
FAN speed according to the actual CPU temperature.
