While increasing fan speed would be helpful, I don't think adding cooling devices is necessarily good advice. Rather than trying to cool the room down, try to exhaust the heat outside the room, so that you are removing heat as opposed to cooling it.
Thx i think this is better idea!
my room is this actually!!!
