JTPM1: TPM Module Connector
This connector is for TPM (Trusted Platform Module). Please refer to the TPM security
platform manual for more details and usages.
CPU_FAN1, PUMP_FAN1, SYS_FAN1~3: 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.
This motherboard can automatically detect PWM and DC mode. However, you can
follow the instruction below to adjust the fan connector to PWM or DC Mode manually.
PWM Mode pin definition
1 Ground 2 +12V
3 Sense 4 Speed Control Signal
DC Mode pin definition
1 Ground 2 Voltage Control
3 Sense 4 NC
Important
You can switch between PWM mode and DC mode and adjust fan speed in BIOS
> HARDWARE MONITOR. And please make sure fans are working properly after
switching the PWM/ DC mode.
