-The thor v2 case has 4 pre built fans and the one on the front has an LED light with it.
-The Asrock Ex4 z77 mobo comes with :
CPU Fan Connector (CPU_FAN1)
Power Fan Connector (PWR_FAN1)
CPU Fan Connector (CPU_FAN2
Power LED Header (PLED1)
Chassis Fan Connector (CHA_FAN1)
Chassis Fan Connector (CHA_FAN2)
Chassis Fan Connector (CHA_FAN3)
Now i was wondering, i have now 4fans and a LED light, and i only have 3 Chassis FAN connectors, how is it possible to install those four when i only have 3 chassis fans connectors on the motherboard
Your case comes with the fan controller, you can connect upto 6 fans (3 for each header A/B) to it. In the overview video you can see what they are at about 4:56 min. If you connect the cpu cooler fan to the fan controller, you may need go to the BIOS to modify the fan control because I don't use the Asrock z77. In most time if you connect the cpu fan on MB that will auto-detect the cpu fan, but if you connect the fan to fan controller then MB can't auto-detect the cpu fan then the pc wouldn't boot.
