These jumpers allow you to connect either a 3-pin or a 4-pin CPU fan
cable plug to the CPU fan connectors (CPU_FAN1, CPU_FAN2). Set
these jumpers to pins 1-2 if you are using a 3-pin fan cable plug, or to
pins 2-3 if you are using a 4-pin plug.

Set these jumpers to +5V to wake up the computer from S1 sleep
mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected USB devices. Set to +5VSB to wake up
from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh,
power supply in reduced power mode).

The USB device wake-up feature requires a power supply that can
provide 500mA on the +5VSB lead for each USB port; otherwise, the
system would not power up.
The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.
