PWM ARGB Case Fans help angielski

(I apologize if it’s the wrong community to post in. If it is,

please do direct me to the correct one)

I have a Maxgreen E275 S02 case with 5 ARGB PWM FANS.

Currently all 5 are diasy chained and are being powered off of 1 SATA cable through some sort of adapter. Does it cause them to run slower than their max speed? (I want them to be running at max if I don’t end up using PWM control)
My Mobo only has 1 SysFan header, so I can’t diasy chain all 5 fans to it as it would go over 1A. If I get a powered PWM hub like the one in the image, can I connect the fans to the hub, then the hub to my 1 SysFan header and still get PWM control using software?
Only one of the fans actually has an ARGB cable and a small 2 pin cable (that’s connected to my reset button, to switch through RGB modes as I don’t have a hub yet) coming out of it, all the rest are daisy chained to it. If I connect that one to a powered ARGB hub, and daisy chain the rest (as they don’t have a ARGB cable), Will I be able to control all the fan RGBs through the hub?
