Fan Headers (Sys_Fan, Cpu_Fan); Chassis Intrusion (Jl1) - Supermicro Supero C7Q270-CB-ML User Manual

Supermicro C7Q270-CB-ML Motherboard User's Manual

Fan Headers (SYS_FAN, CPU_FAN)

Your motherboard has three fan headers
(SYS_FAN 1~2, CPU_FAN 1). These fans
are 4-pin fan headers. Although pins 1-3
of the fan headers (SYS_FAN 1~2) 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.
