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.
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.

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.
