Off-topic: True, fans can't cool below the ambient temperature, but as the safe operating temp. of your PC is between say 50-80 degrees Celsius, I doubt that is lower than the ambient.
Iirc, you use an Acer laptop with integrated Intel graphics, so extra fans aren't easily placed. You could though get a stand with fans to increase the circulation of air and at the very least use a stand to raise the laptop off whatever surface you play on.
A can of compressed air aimed through all your vents and fan openings may also help with any overheating problems.
