You could throw in 26 watters instead of the 42's during really hot weather. Sounds like me, you might not have an air conditioner and it's the general temperature of your rooms that the problems and not just the CFLs.
A closed space, intake and outake is the best way i would imagine, or a really open concept grow room with fans. Everyone here has really good advice about using fans.
What I ended up having to do was install this special fan into my window that costs 30 bucks. It has two 7" fans and is meant to seal into your windowsill, creating suction in the entire room. this fan lowered the general temp in my room and conveniently blew the cool air constantly coming in right towards my closet. Mostly any major harware store has em cheap.
