I have my PC in my room and it makes it like a sauna in there. It gets to 80+ degrees. Even with the colder weather now its still super hot in there.
Is there any way to cool the room without using AC or opening a window?
I have a ceiling fan that runs on high 24/7 and I have another smaller fan that I run quite often but they don't do much.
The ceiling fan HEATS your room. Ceiling fans alone CANNOT cool a room. Same goes with your smaller fan. All you are doing is creating additional heat. Fans make you think it is colder, but they do not actually cool.
Now, if you have adequate room ventillation, your fans can aid in that ventillation. In that case, they can have a very small impact on the temperature. But if that were the case, you wouldn't have posted this thread.
So the first step is to turn off things that generate heat when you aren't using them. That would be your computer, your lights, and your fans.
The next step would be to get proper ventillation. Since we aren't allowed to use the AC, can we at least tell you to turn on the building fan. If your vents and return are unblocked, that'll pump the heat out of your room into the rest of the house/apartment. Opening windows would help, but that is forbidden too.
The next step would be to do as people did for eons: wear less clothing. I know, it sounds impossible. But, believe me, if you are hot, then removing clothing actually helps! Sadly cavemen knew it, but 21st century man has mostly forgotten that little bit of information. Did you know the opposite is true if you are cold? You don't need to turn on a heater you can wear a sweater!
Finally, the most fun thing would be to vent your computer heat out of the room. A hole in a wall/floor and some ghetto tubing would work well. I'm thinking cereal boxes as tubing should be adequate. Plenty of duct tape will seal everything.
