The ASUS P8Z68-V has the following fan headers:

CPU_FAN - 4-pin with PWM fan speed control
CPU_FAN_OPT - 4-pin with PWM fan speed control
CHA_FAN1 - 4-pin with PWM fan speed control
CHA_FAN2 - 3-pin with fan speed monitoring and speed control through ASUS Fan Xpert feature
PWR_FAN1 - 3-pin with fan speed monitoring only. Fan always runs at maximum speed unless the fan has its own voltage drop down resistor(s)/potentiometer.
PWR_FAN2 - 3-pin with fan speed monitoring only. Fan always runs at maximum speed unless the fan has its own voltage drop down resistor(s)/potentiometer.

The four case fans can be connected to the CHA_FAN1, CHA_FAN2, PWR_FAN1 and PWR_FAN2 headers.

When using a 3-pin fan with a 4-pin fan header, the fan is always on; there is no fan speed control.

Fan has a 3-pin power connector; motherboard has a 4-pin fan header

4-Pin Fan Header
1 - Ground
2 - +12 V
3 - FAN_TACH
4 - PWM FAN_CONTROL
