Why should I keep my computer cool?
If you notice that you’re able to play games fine for a few hours before you start seeing issues, this is a sign that your computer may be overheating. If your computer can’t cool itself, it may damage your hardware and shorten the life span of your PC.
If you suspect this could be happening, check your computer’s fans and vents for dust or blockages that could prevent airflow. Use a can of compressed air to clean the inside of your computer and keep it looking brand new. This will help ensure you don’t run into any heating issues.
