UPDATE.

thanks for the link, bug. it did help. i watched it and the guy showed the case sans guts. a thing i never noticed ... BOTH sides of the case open up. who knew?

i opened the right side and saw where the lead from the old dead fan went. followed it to it's connection. disconnected and tossed it.

i also discover FOUR fan leads there and discovered that there is an intake fan in the front lower part of the case (it's not obvious from the outside). i connected two of the four to the two new fans. there is a fan speed switch on the top of the case and now it controls my two new fans.

again, thanks everyone <3
