Fan Help

[coolben]

I am putting together my new light system and I need some help with what fans to purchase. I have a 55g with 2 250w MH with either 130w pc or 260w pc. The hood is opened in the back. Should I use 2 5" fans or 4 3" fans. It is about the same price. Should the fans blow in or out? Thanks

what i did was go to radio shack and got a 12v 300ma power supply and ordered a couple 80mm fans from new egg.. all together i spent about $25
also you want the fans blowing in.. they aren't sealed and if u use them to suck out they'll get salt in em and won't last long.. doesn't matter what kind of fan.. i don't think any are sealed
