is it a big deal the the new pwr supply fan is sucking air into the pc , where as the old one blew air off the pwr supply and out of the pc ?

It's a big deal if you have more than one fan. You need a good flow of air, so one should be pulling air in and the other pushing it out. THE PSU one nomally extracts air. I'd agree - RMA it.
