Do I need to buy a 4 pin Molex Y cable?

Solution
You have one chassis fan if im right from specs of your motherboard, if the fans require molex you can buy splitter from fan header to whatever does the fan require and if the motherboard has DC voltage control for chassis fan you could control fan speed.

Or molex to fan but without control unless you buy front bay controller.
That would be my opinion.
