2.3.3 - Fan Connectors (J27, J28, J59, J60, J61, J62)
This 4-pin fan connector supports a new
standard fan with integrated fan speed
control on the fan itself for better fan life.
The first 3 pins of this 4-pin fan connector
are backward compatible with a traditional
3-pin fan connector without PWM fan
speed control. (Pin4 will be unconnected
for connecting a 3-pin fan).
There are six 4-pin fan connectors on
Thunder i7230A S5160 board.
Support Smart fan ctrl (J27, J28, J60)
Do not support Speed Fan ctrl (J61, J59,
J62)
