3 Chassis fans with one connector on uATX MOB?!

Hi All,
I'm currently building my HTPC with the following relevant components:
Case - Silverstone GD05
MOB - Asus P8H67-M EVO
PSU - Enermax Modu87+ 500W

I have only 1xChassis Fan connector on my MOB (uATX) but I have 3 Chassis fans ... where should I connect them?

  1. Directly to a molex on your PSU usually fans/cases with fans come with adapters.

    What is the amperage rating on the MoBo Header and the amperage of your fans ? Three choices.

    1. Connect to Molex and lose fan speed control.

    2. Gang fans on common header .... total amperage ideally less than 50% of header rating.

    3. Use fan controller

    On option 2 - does it mean that instead of +12V the fans will get +6V? (that might be great ...)

    I've found a connector straight from the PSU (2-pins) to the three fans in my GD05 case accessories and connected 1 fan to it, another fan to the chassis fan controller (so I can control it) and another one to the PWR_FAN, is it ok? can I control the PWR_FAN like this?
