Please see images in linked album above.
The 4pin to 4pin cable is plugged into the CPU FAN header on my mobo.
The 4pin does not power the fans if I plug it into the 4pin port on the hub, with or without the SATA power plugged in.
The 4pin will power the fans if I plug it into a 3pin port on the hub, with or without the SATA power plugged in (this is no use to me as I want to control the fans).
The hub LED will light up if I plug SATA powr in, but fans will not spin unless the cable from mobo is connected to a 3pin port.
4pin port on hub does not seem to do anything.
This is the product I purchased http://www.phanteks.com/PH-PWHUB.html
