Need lighting help please - first time

I have a pc server box, measures 15x7.5 and about 23inches tall. covered with mylar, taped with chrome duck tape. two 120mm intake fans, and two 80mm exhaust fans. the 2 intake fans are on the side. one exhaust fan on top back, and other one on bottom front. I have three 26watt 1750lumens each cfl bulb, but the temperature is in the higher 80's, what do I need to do? any help is appreciated. thanks.
