Purpose for the PWR_FAN plug on a mb

I just acquired an Asus board with a plug marked "PWR_FAN"
I just acquired an Antec Trio 650 PS that has a small matching socket with black & blue wires.
This socket has no markings on it that I can see.

Of course the Antec manual doesn't even acknowledge the existence of the latter, and the Asus manual doesn't specify any particular purpose for the former. :cool:

Since I don't fathom the logic where the PS fan takes back input from the mb that it is contemporaneously powering, my question is: Should I plug the damn line from the PS into the PWR_FAN pins on the board? tia
