Yep! Fan hub controller on computer case (BIOS only sees one fan), where the left white connector is plugged into controls all the fans.
Therefore, remove the connector to the fan hub white connector and disconnect 12-volt Molex power connector from your FAN hub circuit board, because you do not need it (Save in case you want to sell Computer Case later).
Follow the wires from your fans!
Plug the rear fan header into CHA_FAN1 on your motherboard.
Plug the front top fan header into CHA_FAN2 on your motherboard.
Plug the front middle fan header into CHA_FAN3 on your motherboard.
Plug the front bottom fan header into CHA_ FAN4 on your motherboard.
You can use any order you want just remember where you plugged the fan header positions into.
Now you should be able to control all fans (Manual, DC Mode; User Manual page 3-38 to part of 3-41).
