What are the ambient temps in the room that you are drawing air from?
Take you thermometer or hygrometer whatever you use and measure the temps outside the "room".
You can only get your temperatures down to the temp of the air you are pulling in.
Hence, if it is 80F outside the room you won't get your room below 80F ever...(without an airconditioner)
