Fan Headers (Fan 1 ~ Fan 5)
The C7Z87-OCE has ve fan headers (Fan
1~Fan 5). These fans are 4-pin fan head-
ers. Although pins 1-3 of the fan headers are
backward compatible with the traditional 3-pin
fans, we recommend the use 4-pin fans to take
advantage of the fan speed control via IPMI
interface. This allows the fan speeds to be au-
tomatically adjusted based on the motherboard
temperature. Refer to the table on the right for
pin denitions.
