FAN1/FAN2: ONBOARD FAN CONNECTOR (12V)
CPU FAN
SYSTEM FAN
Those connectors support processor/system 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 de-
signed 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.
