Fan Headers (Fan 1 ~ Fan 4)
The C7B75 has four fan headers (Fan 1~Fan 4).
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 in the BIOS Hardware Monitoring
section. This allows the BIOS to automatically
adjust fan speeds based on the motherboard's
detected system temperature. Refer to the table
on the right for pin definitions.
