I've got a 172cfm Vortex fan for the carbon scrubber, but I'm also gonna need cooling for my 6" Cool Breeze reflector (holding a 600w Hortilux).

It'll be inside of a DR 120 (3.9' x 3.9' Secret Jardin Dark Room), which size fan will I need to keep it around 75-80 degrees? Would something like this: 6 In. 110VAC 250CFM In-Line Duct Fan - 3011 at The Home Depot work? 250 CFM inline duct fan from Home Depot for $33.99.
