buckdatass, I had the same brob with temp in my room i had 2 large exaust fans taking air out,but i found it didnt do much good so i got more fresh air pumped in and took 1 of the exaust fans out now i can control the temp better as more fresh air keeps temp down better and if the exaust isnt getting all thehot air out it will escape from some were and new air will keep temp down. well it works for me ,
