6x 120mm PC fans.

4 - Exhaust
2 - Intake

One small oscillaiting fan aimed at the hood.

What are the temps and RH in there when the lights are on? If it's autoflower why don't you grow them outside the box?

I honestly think with temps like your reporting, i would go with CFL's in that closed space. Your light is too powerful for your grow cabinet.

Here looks like a lot of reading but its not and it IS worth it just start poking around the CFL sub forum https://www.rollitup.org/cfl-growing/107992-tutorial-growing-cfls.html

Have you looked into T5's? It looks like a 2 foot 4 bulb would fit in there well.
