two exhaust with one inline on the intake. but only if the intake can match the exhaust so as to not create negative pressure in the tent.

in that case i would use the inline to air cool your light and the other two as intakes.

the aircooled light would be your exhaust you would need to use ducting to direct the air away(exhaust).

i have a tent and to keep it cool i use 2 fans and 2 exhaust, with one fan and 2 exhaust it makes no sense, and negative pressure is what you want in order to keep temps in check, if you want to maxamize the fans keep them on their own exhaust
