Does anyone know the official limit for for the pwm fan headers on these mobos?

I always thought they were somewhere in the range of 10watts but I hooked up two 15 watt fans for a total of 30watts with all the power coming from the header and they completely maxed out 100% at over 5600rpm each.  These were the chassis headers, not the cpu.

If the header can deliver the power is it all good?  Or would it eventually fry out somewhere?  I mean it's only 30 watts and the pins aren't that small.

I am wondering because I need to hookup some powerful fans and I want to have control of them via software remotely from any location in the world. vs getting fan controllers.

Thoughts?

Also what about the video card PWM fan header, what is the voltage output on those?

and before anyone asks, yes I am running 120v regular fans for cooling.  my questions here are related to something else.
