running fans on slims

[ironcobra570]

i know that voltage for the ps2 is 8.5 and i want to try and run 1 or 2 12v fans without sacrificing air flow. at this point i havnt totaly figured out my disign but i want one fan intake and one fan exaust for cross ventalation, but i dont think a ps2 can power an extra 24v so i think ill be stuck with one fan (probly intake)
 so any ideas leme know,pics to show points would be mad sic

can be done wth one 12 volt fan ... i got  4 leds clear fan ($4 from hong kong) on my ps2 slim ...  all i did was cut out the window of slim and install the fan .    and added a switch for it too .....  looks good .. and works fine
