I've had my PC for about two years, and it seems to be running well. When I'm gaming, temperatures sit between 65-75°C, which I believe is normal. However, my setup gets quite warm, and I find that it makes me a bit anxious about overheating, even though I know it's not. I really don't want to mess with the inside of my PC because building it was a hassle for me. I'm considering using external fans, maybe positioning one behind the PC to blow air toward me. Has anyone tried this? Is it a good idea? I'd appreciate any advice!

Just keep in mind that temperature and heat output are different. If your PC is generating too much heat for the room, you might need to either vent that heat out or look into better efficiency options instead of just circulating air faster. Placing fans nearby won’t change the overall outflow from the components – it’ll just warm the room up quicker.
Using external fans might help prevent heat buildup around the PC, but it really depends on how effective they are in reality. Just remember, they can contribute noise too, so choose wisely if noise levels are a concern for you.
External fans won’t significantly change your internal thermodynamics. With your temps being optimal, you might just need airflow directed towards you to avoid discomfort. Just ensure not to block any rear exhaust vents, as your case is designed for a certain airflow balance.
If you're just trying to move warm air away from you, adding a small fan could work fine. Just avoid pointing it directly at any exhaust vents to keep airflow optimal.
Yeah, I agree! Just keep the design of your setup in mind to prevent any obstruction.
Honestly, using external fans might just heat up your room faster. I’d recommend keeping your case clean, maybe re-pasting your CPU if you haven’t done it in a while. That’s usually a better way to ensure good cooling without changing your setup too much.

Good point! Moving the PC to a cooler room or improving airflow around it might help more long-term.
