Fan Headers
There are six 4-pin fan headers on the motherboard. Although these are 4-pin fan headers,
pins 1-3 are backward compatible with traditional 3-pin fans. The onboard fan speeds are
controlled by Thermal Management (via Hardware Monitoring) in the BIOS. The fan speed
is controlled by the BMC.
