good I am glad you did not feel too angry.
so lets go slow to a fix.
1 unit in the box how big is the box and how big are the tubes you use?
also how long are the tubes?
big tube diamater help 10 inch not six inch.
shorter tubes help
how warm is the room?
70f = good
80f = okay
90f = not so good
100f = bad
next the exhaust tube gets the air out of the room correct?
If you have a long exhaust tube it will need a fan to pull the air out.
I'm attaching two pics:

Temperature in the room is okay. And in fact pipes are 6 inchs.
I'm planning to build this cooler:
