I had the same problem but solved it! with my home made air conditioner!!
this is what i have, i made a box out of Lexon Plastic, and i have a big radiator in it, in the back of the box i have drier hose running from my computer power supplies into the box and a fan on the front of the box to pull the cooled air out. then i have a small fill-point resivour on top of the box with a pump that pumps water into the radator and out, then i have water lines running to my bassment, to another small radior so the water can be cooled. i have pics of it online go to...

my room was getting to 88 degrees too, and with this cooler i managed to keep it in the low 70s. the cool box itself takes in air from 88-95 degrees and cools it an average of 15 degrees, so the head my computers produce never goes into my room!
it works great, it cost around $300 total, but i am in the processes of adding some more to get it to actually "air-condition" my room!
