Fan Headers
There are five 4-pin fan headers (CPU_FAN1 ~ CPU_FAN2, SYS_FAN1 ~ SYS_FAN3) on
the motherboard. Although Pins 1-3 of the system fan headers are backwards compatible
with the traditional 3-pin fans, the 4-pin fans are recommended to take advantage of the fan
speed control. This allows fan speeds to be automatically adjusted based on the motherboard
temperature. Refer to the table below for pin definitions.
Pump Power Header
This motherboard has one +12V header for optional CPU liquid cooling systems. When using
a liquid cooling system, attach the pump power cable to the 12V_PUMP_PWR1 header.
