31Overview of Components S ATA1~ 6: S ATA 6 G b/s C o n n e c to r s These connectors are SATA 6Gb/s interface ports. Each connector can connect to one SATA device. S ATA 5 S ATA 1 S ATA 6 S ATA 2 S ATA 3 S ATA 4 Important yPlease do not fold the SATA cable at a 90-degree angle. Data loss may result during transmission otherwise. ySATA cables have identical plugs on either sides of the cable. However, it is recommended that the flat connector be connected to the motherboard for space saving purposes.

35Overview of Components CPU_FAN1, PUMP_FAN1, SYS_FAN1~4: Fan Connectors Fan connectors can be classified as PWM (Pulse Width Modulation) Mode or DC Mode. PWM Mode fan connectors provide constant 12V output and adjust fan speed with speed control signal. DC Mode fan connectors control fan speed by changing voltage. When you plug a 3-pin (Non-PWM) fan to a fan connector in PWM mode, the fan speed will always maintain at 100%, which might create a lot of noise. You can follow the instruction below to adjust the fan connector to PWM or DC Mode. Default PWM Mode fan connectors Default DC Mode fan connectors 1 CPU_FAN1 1 SYS_FAN1/ SYS_FAN3/ SYS_FAN4 1 PUMP_FAN1 1 SYS_FAN2 PWM Mode pin definition 1 Ground 2 +12V 3 Sense 4 Speed Control SignalDC Mode pin definition 1 Ground 2 Voltage Control 3 Sense 4 NC Switching fan mode and adjusting fan speed You can switch between PWM mode and DC mode and adjust fan speed in BIOS > HARDWARE MONITOR. Select PWM mode or DC mode Important Make sure fans are working properly after switching the PWM/ DC mode. There are gradient points of the fan speed that allow you to adjust fan speed in relation to CPU temperature. Pin definition of fan connectors
