ASRock Z77 Extreme4 with Rosewill Blackhawk - How do I connect fans?

Hi Again. I am building a new computer, first time from scratch. I am pretty comfortable with everything, except for the fans. I would like to be able to control the fans through the board, but I only have my computer on when I am using it. It rarely ever sleeps or goes idle.

CASE: ROSEWILL BLACKHAWK RTL (Newegg Item 11-147-107)
MOTHERBOARD: ASRock Z77 Extreme4
POWER SUPPLY: PSU ROSEWILL | HIVE-750 750W RT

The motherboard has the following connections:
CPU-FAN1 (4 pin) - I plugged in the fan for the Hyper EVO 212 here
PWR-FAN1 (3 pin) - open
CPU-FAN2 (3 pin) - open
CHA-FAN1 (4 pin) - open
CHA-FAN2 (3 pin) - open
CHA-FAN3 (3 pin) - open

The case has 5 fans: 2 front, 1 rear, 1 top and 1 side. All have big 4 pin connectors. The power supply is modular. One of the cords provided has 5 plugs: a 6 pin plug that fits into the power supply, three large 4-pin connectors that match the fan connectors and a small 4-pin plug that matches a plug on the motherboard. Can I use that cord? And if I do use it, do I plug it into the power supply, the fans (3) AND the motherboard? Sorry for the dumb question, but I am losing sleep lol.

Another related question: Can I use the five open fan connectors on the board for case fans even though there are only 3 fan connections labeled for case use? (can I plug a chassis fan using an adaptor into the PWR-FAN1 and CPU-FAN2?)

Thanks in advance for your help. :D

You only need 1 fan on the EVO , so use all the others for your fans.

The other fans have molex so he cannot plug them in... to the board anyway... most case fans have speed settings just set them at the speed you want there is no real reason to controll them by the board... I know some people like to but with 5 fans I really doubt you will run into a case where you need higher case airflow...
