4. Fan control setting (3-pin CPUFAN_SET1, CHAFAN_SET1)
These jumpers allow you to switch for fan pin selection. The CPUFAN_SET1
jumper is for the CPU fans control and CHAFAN_SET1 is for the other fans
control including front fans, rear fans and FB-DIMM fans. Set to pins 1–2 for
4-pin fans or pins 2–3 for 3-pin fans.
5. Onboard storage setting (3-pin SAS_EN1)
This jumper allows you to enable or disable the onboard LSI1068 SAS
controller. Set the jumper to pins 1–2 to enable the SAS function (default).
• 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.
