Fan Header
This motherboard only has 4-pin fan headers, which are backwards compatible
with 3-pin fan connectors. CPU1 and CPU2 controls fans via PWM. The
remaining headers control fans by either PWM or DC controls. The headers
have an absolute safe power limit of 2 Amp @ 12 Volts (24 Watts). These
headers are for your CPU heatsink/AIO and chassis cooling fans.
