OK. So my grow box keeps moving from 24-31 depending on temperature outside. ( I don't have central air ). I will be putting in sir conditioner in apartment next week... but it's not even hot yet outside.. reached a high of 20 Celsius and my box was 32. So regardless if i cool the room it wont do that much when the heat really comes in thus summer. 20160418_183135.jpg 20160418_183122.jpg 20160418_183052.jpg 20160418_183042.jpg 20160418_183023.jpg 20160418_182942.jpg 20160418_183034.jpg What am I doing wrong ? I'm using 200w cfl and will be adding 2 t5 cdl vertically on wall for flowering. What can I do to make it cooler ?

If that is an HID lamp in that small area you definitely need to rethink your grow room. It either has to be big enough to allow more airflow AND adequately house an air-cooled reflector. Or, you may want to consider another lighting source.

It is CFL 200w. I just drilled 2 more holed added my fan to top hole and leaving other 2 holes open they seem to be pulling in lots of air without 2 more fans. Should I add 2 more computer fans for intake? Temps seem to be good.20160419_082711.jpg 20160419_082756.jpg

No no, im saying get rid of the computer fans. Buy a 6" or 8" inline fan. those computer fans are not enough for a space that large. Even if your temps are okay, your plants still need fresh air regardless of temperature.
