It's not the fans, they only draw a few watts each. The PCI-E cables run off Rail 3 or Rail 4. When you put 2 overclocked 470's on there, I'm sure they are trying to draw more than 25A per rail.

I'd try it with one 6+2-pin and one 6-pin to each card, at stock. If it runs ok, put your OC back on and see if you have issues. If so, get a single-rail PSU, or one with more Amps on each rail.
