I've got a bulky Acer PC that turns my room into a sauna after about 30 minutes of gaming. My air conditioning isn't very effective since the thermostat is in another room. In winter, I could just crack open a window, but with summer heat, that's not an option. I'm considering getting a portable A/C unit to vent heat out the door, but since my window isn't suitable for any venting solutions, I'd love to hear your suggestions or alternatives to keep my room cool while I game. Thanks!

Honestly, your best bet might be to decentralize the heat source. If you can't vent the heat out using fans or AC, consider moving your PC to another room entirely. It will help reduce the heat in your gaming space!
If possible, undervolt your CPU and GPU to reduce heat output. If that's not an option, A/C might be your only reliable solution. Also, capping your frame rates can help too; there's no need to run above your monitor's refresh rate!
One option is to move your PC to another room and use USB or HDMI cables to connect it to your setup. That way, you won't have to deal with the heat in your room while gaming.
I have my gaming setup in my office and I manage the heat by using a ceiling fan along with a small desk fan that pushes warm air out. Plus, I added a vent booster to draw in more cool air, which really helps!
Using a box fan can really help circulate air in and out of the room. Also, try maximizing the efficiency of your PC components. I wouldn’t recommend venting an AC unit out the door since it might not work effectively. But if your windows open at all, there are units designed to fit those openings that might work better than you think. Let me know what you decide!

1. I might give the box fan a shot, but I prefer to keep my door shut.
2. My PC needs to perform at its peak for several tasks beyond just gaming, unfortunately.
3. I thought about making a custom exhaust attachment for the portable AC that fits under the door, but I'm worried that may be impractical. My window only opens outward with vertical hinges, so I'm not sure if that's a viable option.
