On the Asus H97-pro:

PWM CPU: CPU cooler PWM fan
PWM CPU_1: Hub to control fans via PWM signal from motherboard
DC CHA_1: 3pin controlled by DC voltage with fan xpert software.

If i use a simple fan hub to a CPU_1/CHA_1, how many fans (2000 RPM) can be connected safely as to not overload the header?

If the fan hub is powered by molex to PSU, can i connect it to the CHA_1 header still? to control fan speed via motherboard.

Hi
The safest way is to use one of these as the speed is controlled by the motherboard but the power for the fans comes direct from the PSU and so you cannot overload the motherboard.
