4.2 Headers and Connectors
Fan Headers (Fan 1 - Fan 5)
Your motherboard has fi ve 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 defi nitions.
