Dorms are too hot!

I'm in Harper. All Winter I have had my windows FULLY open. The only time it gets remotely chilly in the room is when it is 10 F outside. Anything above that and it is impossible to sleep because of how hot the dorm is. I have tried turning the thermostat off or on at the coldest I can turn the knob too, and it never feels any different. Why? Now that it's warming up outside, too, it is genuinely unbearable. Can't even bedrot comfortably :(
