I had the same problem! This specific laptop is prone to collecting dust and debris in the fan overtime, so it's not your fault. The dust is what is causing the laptop to overheat--it can easily be fixed by disassembling the laptop and cleaning out the fan with compressed air. That should do the trick! If not, you may need to replace the fan. Another tip is to make sure you're allowing the fan to ventilate while you're using the laptop, so try to avoid using it on your lap, blanket, or any other soft surfaces. Hope this helps!
