Just hook the 5 volt fan on 1 battery - esc lead. I'm powereing 1 5 volt fan and 1 12 volt fan off 1 battery and it does the trick easy.

I'm not a comp nerd at all, but sucking air away from the cpu is not the way you want to cool thing's. I've done some modding to a few pc's, including putting sweet cpu cooler's on which all blow air on the cpu, not sucking heat away from it. You can alway´s try, but be prepaired for a over heating cpu.
