The case has 4X 120mm fans. Each fan has a male and female 4 pin molex, none have the little 4 pin that would connect to motherboard sys fan header. The motherboard only has 2 4pin fan headers, the cpu fan and sys fan.
The wire bundle from the power supply has 2 male molex 4 pin and 1 small 4 pin which would fit the mobo header.
Do I daisy chain the fans and then connect the small 4 pin from the wire bundle to the sys fan? Or ignore the small 4 pin from the wire bundle? Should I connect each fan directly to the psu (each fan getting it's own molex connector off the power supply)?
You can daisychain, but do not plug the little four pin from the Psu into the motherboard, it is for a floppy drive (which most folks don't have anymore)
that doesn't get used at all,
just plug them into the Molex line
