Chapter 2 Hardware Setup
These fan connectors support CPU/System/chassis cooling fan with +12V.
When connecting wire to FAN connectors, users should pay attention
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. If your mainboard 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 speed sensors, each rotation of the fan blades will send out
2 electric pulses, by which System Hardware Monitor will work out the
fan rotation speed by counting the pulses.

NOTE:
1. Always consult vendor for proper CPU cooling fan.
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.
3. We use 3 “Yellow” fan connectors to mark that they support fan speed
sensor function.
