Supermicro C7Z270-CG Motherboard User's Manual
Fan Headers (Fan 1 ~ Fan 5)
Your motherboard has five fan headers
(Fan 1~Fan 5). These fans are 4-pin fan
headers. 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. This allows the
fan speeds to be automatically adjusted
based on the motherboard temperature.
Refer to the table on the right for pin
definitions.
Chassis Intrusion (JL1)
A Chassis Intrusion header is located at
JL1 on the motherboard. Attach the ap-
propriate cable from the chassis to inform
you of a chassis intrusion when the chassis
is opened.
