Hood Oppinions Needed

[SkiFletch]

So as some of you know, I'm building a hood for my tank and am looking for some oppinions on fans. The framing of the hood is allready cut and the inside stained white. Next step is to notch out my overflows in the back and notch out some holes with the jig saw. I've designed the hood with a lot of room for fans since its 12" tall. I was thinking some 120mm A/C fans (since I'll have plenty of A/C wiring for the lights). But how many should I put in there? I was leaning towards having two pushing air into the hood and two interior pointed at my water level for extra evap cooling. Exhaust would happen through the extra room created by notching out the overflows. What do you guys think of that?

I would go for two in at one end and two out at the other as low down on the hood as I could.

Sounds pretty good also if u adapt it to say a pc case, have one sucking out the hot air on one side then one next to it blowing air in. then have the same but opposite on other side. that way the hood is being cooled but also helps to take out the hot air.
