Have I damage the motherboard? Connected my pwm hub wrong.

Hi,
I did troubleshoot all day why my fans that was connected to the PWM hub was working but the BIOS did not show any RPM.
So then I was looking at the PWM hub and I did discover that I had connected the motherboard to FAN 1 port in the PWM hub instead of the CPU port in the hub that's the correct one for the motherboard to the hub.
And I'm wondering if I can have damage my motherboard as the FAN 1 port are sending power to the fans so now I guess that my PWM hub has sent power to my motherboard header and I guess that the header are not made to recive power? Or is it some kind of fail safe so the header can't damage it self or the motherboard?

Here's a picture of how it's connected from the maker of the Hub.
