3.9 CPU Fan Connector (CN11, CN17, CN18)
The ROCKY-P288EV provides two CPU cooling fan connectors,
CN17 and CN18 as well as a chassis fan connector, CN11.
These connectors can supply 12V/500mA to the cooling fan. All
connectors have the same pin assignments and provide a
"rotation" pin to get rotation signals from fans and notice the
system. So the system BIOS can recognize the fan speed.
Please note that only specified fan can issue the rotation signals.
