IR (INFRARED RAYS) CONNECTOR
3.3.16 CN13: COOLING FAN 1 POWER CONNECTOR
CN13 is the cooling fan power connector designed on the mainboard. Since it is
very close to the Socket A connector, so CN13 is recommended to connect to the
CPU cooling fan. You can see from the BIOS setup program the cooling fan
speed. When the device driver of the hardware monitoring is installed, you can
monitor the rotating speed of the CPU cooling fan in the Windows operation
system.
