I have a pretty bulky Acer PC, and I've noticed that after about 30 minutes of gaming, my room gets incredibly hot—like a sauna level! My air conditioning isn't helping much since the thermostat is in a different room. During the winter, I can just open the window to cool things down, but it's summer now. I'm considering a standalone AC unit that I could vent out of my door since my window setup is not compatible with most AC designs. I'm curious if anyone has other solutions or experiences with this kind of problem. Thanks!

If you can, undervolting your CPU and GPU can help reduce heat. Setting a frame rate cap could also help; there’s no need to run above your monitor’s refresh rate.
Consider relocating your PC to another room and using USB/HDMI cables to connect it. This way, the heat won’t be a problem in your main room!
Using a box fan could help circulate the air in and out of your room. Also, consider enhancing the efficiency of your PC components. Just a heads up, an AC venting out of the door isn’t optimal. If your windows open, there are portable units that can vent through a window opening. Also, have you checked to see if there's a way to modify the window for a better fit?
The best real option might be to decentralize the heat. If you can’t vent the heat outside with fans or AC, moving the PC to another room could be your best bet.
I keep my gaming PC in my office and it works well! I use a ceiling fan and a small desk fan that blows warm air out. Plus, I've got a vent booster that pulls extra air into the room, which really helps with cooling.

1. I can definitely try the box fan, but I like to keep my door closed most of the time.
2. My PC needs to maintain max performance for reasons beyond just gaming.
3. I thought about making a custom exhaust for the AC that slips under the door, but it might not work as planned since my casement window opens outwards.
