Warm air being pushed through will still help a great amount, my room is normally 80-85 and I have not problems with any of my computers that have fans, use fans even if your room is hot. Just think about it like this, if a room is extremely hot you can still do something to cool yourself off like a fan to blow the air around or directly at you to help comfort yourself from the heat. The same works for computers, even if the room was 100 degrees and you had enough fans your system still would stay cool enough, without any fans your system with most likely overheat with any kind of load.
