ventilation help pleaseee

[im high right now]

is a 50cfm exhaust fan powerful enough for my 3x3.5x7.5 closet? or do i need to get a higher powered fan? i have 1 70w hps, 2 65w cfls, and 7 26w cfls. the two big cfls are up above inline with the hps in the center with the cfl heights off a little from the hps to be closer to plant tops. i will either be getting another 70w hps or a 150w hps in the next week or so, so i need to get my vents strait by then to deal with the heat. i know the hps are small but heat and price are factors right now for this grow
