2. CPU Fan and Chassis Fan control setting (3-pin CPUFAN_SEL1, CHAFAN_SEL1) These jumpers allow you to switch for fan pin selection. The CPUFAN_SEL1 jumper is for the CPU fan control and the CHAFAN_SEL1 jumper is for the front fans and rear fans control. Set to pins 1-2 when using 4-pin fans or pins 2-3 when using 3-pin fans. • If you use a 4-pin fan but set the jumper to pin 2-3, the fan you installed may not work. • If you use a 3-pin fan but set the jumper for a 4-pin fan, the fan control will not work and the fan you installed will always run at full speed. 3. LAN controller setting (3-pin LAN_SW1, LAN_SW2) These jumpers allow you to enable or disable the onboard Intel® Intel 82574LGigabit LAN controllers. Set to pins 1-2 to activate the Gigabit LAN feature. 2-20 Chapter 2: Hardware information
